Important: This calculator provides estimates using a simplified Income Shares Model for educational purposes only. Actual child support calculations vary significantly by state (Your State) and individual circumstances. Courts consider many factors including deviations, caps, and state-specific guidelines. Consult with a family law attorney in Your State for accurate calculations specific to your situation.
Understanding Child Support
Child support is financial obligation paid by non-custodial parent to custodial parent to help cover costs of raising children. Unlike spousal support which varies widely, child support uses standardized formulas in all 50 states based on either Income Shares model, Percentage of Obligor Income model, or Melson Formula.
Child Support Models by State
Income Shares Model (41 States)
Most common approach used by 41 states. Based on principle both parents should contribute to child costs in proportion to their income as if family were intact. Combines both parents income, determines base obligation from state schedule, prorates amount by each parent income percentage.
How It Works: Step 1 - Add both parents gross monthly income. Step 2 - Look up combined income on state schedule to find base child support obligation based on number of children. Step 3 - Calculate each parent percentage of combined income. Step 4 - Multiply base obligation by non-custodial parent income percentage. Step 5 - Add extraordinary expenses like health insurance and childcare prorated by income share.
Example Calculation: Parent A earns 5000 monthly Parent B earns 3000 monthly. Combined 8000. Two children. State schedule shows base obligation 1400 monthly for 8000 combined income with 2 kids. Parent A percentage: 5000 divided by 8000 equals 62.5 percent. Parent B percentage: 3000 divided by 8000 equals 37.5 percent. Non-custodial Parent A pays: 1400 times 0.625 equals 875 monthly. Add health insurance 200 monthly times 0.625 equals 125. Add childcare 600 monthly times 0.625 equals 375. Total: 875 plus 125 plus 375 equals 1375 monthly.
States Using Income Shares: Alabama, Arizona, California, Colorado, Connecticut, Delaware, Florida, Georgia, Hawaii (Melson variation), Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Montana (Melson variation), Nebraska, New Hampshire, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Utah, Vermont, Virginia, Washington, West Virginia, Wyoming.
Percentage of Obligor Income Model (7 States)
Simpler model based solely on non-custodial parent income. Applies percentage to obligor gross or net income based on number of children. Custodial parent income not considered in basic calculation but may factor in shared custody adjustment.
How It Works: Calculate obligor net or gross income. Apply state percentage based on number of children. Common percentages: 20 percent for 1 child, 25-28 percent for 2 children, 30-35 percent for 3 children, 35-40 percent for 4 plus children. Add health insurance and childcare as percentage of obligor income or flat amounts.
Example Calculation - Texas: Non-custodial parent earns 6000 gross monthly. Two children. Texas percentages: 25 percent of net income for 2 children. Net income approximately 4500 after taxes. Support: 4500 times 0.25 equals 1125 monthly. Texas caps at lesser of percentage or 9200 monthly (adjusted annually).
States Using Percentage Model: Alaska: 20-27-33-36-40 percent gross based on children 1-5 plus. Arkansas: 14-20-23-25-26 percent net for 1-6 plus children (hybrid Income Shares over 25000 combined). Mississippi: 14-20-22-24-26 percent adjusted gross for 1-5 plus children. Nevada: 18-25-29-31-34 percent gross for 1-5 plus (40 percent custody adjustment). North Dakota: 14-20-22-24-27 percent net for 1-5 plus. Texas: 20-25-30-35-40 percent net for 1-5 plus children (lesser of percentage or dollar cap). Wisconsin: 17-25-29-31-34 percent gross for 1-5 plus.
Melson Formula (3 States)
Complex three-tier approach: ensures minimum self-support reserve for each parent, covers basic child needs, enhances standard of living if income exceeds basic needs. Promotes child sharing in parent increased prosperity beyond necessities.
Three Tiers: Tier 1 - Self-Support Reserve: Each parent entitled to keep income sufficient for basic self-support (poverty level amount). Tier 2 - Primary Support: Child entitled to primary support covering basic needs from remaining parental income. Tier 3 - Standard of Living Allowance: If income exceeds basic needs after self-support and primary support, child shares in additional prosperity through percentage of remaining income.
States Using Melson: Delaware, Hawaii, Montana. Most complex calculation requiring detailed worksheets. Accounts for each parent actual basic needs and child needs at different income levels.
What Income Counts for Child Support
Income Included
Employment Income: Wages and salary, overtime pay and shift differentials, bonuses and commissions, tips and gratuities, severance pay, contract or 1099 income, military basic pay and BAH (Basic Allowance for Housing).
Self-Employment Income: Gross receipts minus ordinary and necessary business expenses. Courts scrutinize deductions to prevent income manipulation. Personal expenses disguised as business added back. Depreciation often added back as non-cash expense. Cash businesses face extra scrutiny.
Investment and Property Income: Rental property income (gross rents minus expenses), interest and dividends, capital gains, royalties, partnership or trust distributions, estate or inheritance income flows.
Government Benefits: Unemployment compensation, workers compensation (wage replacement portion), temporary disability benefits, Social Security retirement or disability benefits (not SSI), veterans benefits, pension and retirement income.
Other Income: Spousal support or alimony received from prior relationship, annuity payments, lottery or gambling winnings (if regular), severance packages, signing bonuses.
Income Excluded
Means-Tested Benefits: Supplemental Security Income SSI, Temporary Assistance for Needy Families TANF, food stamps SNAP, public housing assistance, Medicaid.
Child-Related: Child support received for other children, foster care payments, adoption subsidies, child tax credits.
One-Time or Windfall: Gifts (unless regular pattern), inheritance lump sums (not ongoing income), personal injury settlement (pain and suffering portion), life insurance proceeds.
Adjustments and Add-Ons
Health Insurance
Cost of health insurance premiums covering children added to base support. Prorated by income share in Income Shares states. Paid by obligor or added to monthly payment in Percentage states. Include only portion attributable to children not parent coverage. If employer subsidizes, use actual out-of-pocket cost. Dental and vision insurance also included.
Childcare Costs
Work-related childcare expenses for children under 13 or special needs older children. Must be necessary for parent to work or attend education increasing earning capacity. Actual costs not theoretical. Prorated by income share. Before and after school care, daycare, summer programs, nanny or babysitter during work hours. Not extracurricular activities or enrichment unless agreement.
Extraordinary Medical Expenses
Unreimbursed medical, dental, vision expenses not covered by insurance. Orthodontia, therapy, prescription medications, medical equipment. Typically prorated by income share. May require threshold (first 250 dollars per year) before sharing kicks in. Include only expenses for children not parent.
Educational Expenses
Private school tuition if established pattern or agreed. Special education for learning disabilities. Tutoring if medically necessary. Most states do not require private school unless historical pattern or agreement. College expenses typically not included in child support, separate issue.
Extracurricular Activities
Sports, music lessons, clubs, camps. Generally not required but can be agreed. If child historically participated or activity provides special benefit, may be ordered. Typically capped at reasonable amount.
Shared Custody and Parenting Time Adjustments
Thresholds for Adjustment
Most states adjust support when non-custodial parent has significant parenting time. Common thresholds: Ohio: 90 overnight visits per year (approximately 25 percent time), Illinois: Over 146 overnights (40 percent plus), Pennsylvania: 40 percent plus overnights, Connecticut Maryland: 35 percent plus time, Texas: 35 percent plus possession, Wisconsin: 25 percent plus time, North Carolina: Over 123 days, Alabama: 127 plus overnights.
Rationale: When child spends substantial time with non-custodial parent, that parent incurs direct expenses for housing, food, utilities, clothing during their parenting time. Reduces custodial parent expenses for those days. Fair to reduce support payment to account for expenses both parents incur.
Calculation Methods
Shared Parenting Worksheet: Many states have separate worksheet for shared custody. Calculates each parent theoretical support obligation if they were non-custodial. Offsets obligations resulting in net payment from higher earner to lower earner or reduced payment. Accounts for percentage of time child with each parent.
Example - Colorado Worksheet C: Parent A earns 7000 monthly has child 40 percent time. Parent B earns 4000 monthly has child 60 percent time. Combined 11000. Two children base obligation 1900. Parent A theoretical obligation: 1900 times 0.636 (7000/11000) equals 1208. Parent B theoretical obligation: 1900 times 0.364 equals 692. Apply time adjustment. Net payment Parent A to Parent B after adjustment approximately 400-600 monthly much less than standard calculation.
Income Disparity Still Matters
Even with equal 50-50 parenting time, if large income disparity exists, higher earner typically pays something to lower earner. Goal is child enjoys similar standard of living in both households. Equal time does not always mean zero support.
Duration of Child Support
Age Limits by State
Age 18 or High School Graduation: Most common rule. Support continues until child turns 18 AND graduates high school, whichever is later, but typically not past age 19. Examples: Ohio, California, Florida, Pennsylvania, Virginia. If child turns 19 before graduating, support usually ends at 19.
Age 19: Some states extend to 19 regardless of graduation. Alabama (19 or graduation whichever first), Alaska, Indiana, Nebraska, South Dakota, Utah. Nebraska extends to age 19 or high school graduation if still enrolled.
Age 21: Extended support in some states. Mississippi (21), New York (21), Oregon (21 if still in school), New Hampshire (21 if in high school full-time).
Age 23 or Beyond: Hawaii (23), Massachusetts (21-23 depending on circumstances), New Jersey (may extend through college to age 23).
Termination Events
Child support ends when: child reaches age specified in order, child graduates high school (in states using graduation trigger), child becomes emancipated (marries, joins military, self-supporting), child is adopted by another person, child or parent dies, court order terminates or modifies support.
Emancipation: Legal status where child no longer under parental control. Factors: child financially independent, child married, child enlisted in military, child living independently with parental consent. Must petition court for emancipation declaration in most states, not automatic.
College Support
Varies dramatically by state. Some states can order parents contribute to college: Massachusetts, New Jersey, Illinois, Connecticut, New York (in some cases), Hawaii, Indiana (if agreed), Oregon. Other states cannot order college support: Texas, Florida, North Carolina, Arizona. If parents want college support, must agree in settlement and specify terms: which colleges acceptable, how much each pays, conditions (grades, full-time enrollment), duration (4 years, specific degree).
Modification of Child Support
Grounds for Modification
Income Changes: Either parent income increases or decreases significantly. Threshold typically 10-20 percent depending on state. Job loss or reduction in hours. Promotion or raise. Change in self-employment income. Involuntary changes stronger grounds than voluntary.
Parenting Time Changes: Custody arrangement changes (sole to joint or vice versa). Parenting time increases or decreases crossing shared custody threshold. Child moves from one parent to other. Substantial change in overnight visits affecting calculations.
Child-Related Changes: Number of children supported changes (younger child emancipates). Child expenses increase (health insurance, childcare costs). Extraordinary medical needs develop. Child starts private school if obligor agrees.
Other Substantial Changes: Either parent remarries and household income substantially changes (some states). Payor has additional children creating new support obligations. Recipient cohabits reducing expenses (limited recognition). Cost of living increases in some states (COLA provisions).
Periodic Review
Many states allow review every 3 years even without change. Either party can request review. Child support enforcement agency conducts review. Ensures guideline amounts kept current as incomes change over time. Particularly important for young children where support relationship lasts 15-18 years.
Retroactivity
Modifications typically effective from date of filing motion not hearing date. Cannot be retroactive before filing except in limited circumstances. Important to file modification quickly when change occurs to avoid accumulating arrears at old rate. Some states limit retroactivity to 3-6 months before filing.
Imputed Income
When Courts Impute
Court assigns income based on earning capacity not actual earnings if parent voluntarily unemployed or underemployed without good cause. Prevents parent from avoiding support by refusing to work or taking lower-paying job.
Factors Considered: Recent work history and earnings (past 5 years). Education level and training. Professional licenses and certifications. Age and health affecting employability. Local job market and available positions. Skills and experience in field. Reason for reduced earnings or unemployment.
Good Cause for Reduced Income
Acceptable Reasons: Caring for child under age 3 or disabled child. Documented disability preventing work. Attending approved education or training program increasing future earning capacity. Verified economic conditions (recession, plant closing). Retirement at reasonable age after long career.
Unacceptable Reasons: Voluntary career change to lower income to avoid support. Quitting job without good reason. Refusing available work in field. Taking lower job when higher paying available. Voluntary unemployment to pursue hobby or personal interest. Early retirement solely to reduce support.
Calculation Methods
Imputed income based on: median income for person with obligor education and experience in local market, income at last full-time employment, minimum wage for 40 hours weekly (baseline), actual offers of employment declined, vocational expert testimony on earning capacity. Court has discretion in choosing method but must use reasonable basis.
Enforcement of Child Support
Automatic Income Withholding
Federal law requires immediate income withholding for all child support orders. Employer withholds from paycheck and remits to state agency or custodial parent. Begins when order entered not after arrears accumulate. Most effective enforcement method with over 70 percent collection rate. Can withhold up to 50-65 percent disposable income depending on whether supporting other children.
State Enforcement Agencies
Every state has Child Support Enforcement (CSE) agency providing free services: locate absent parents, establish paternity, establish support orders, enforce support orders, collect and distribute payments, modify orders when appropriate. Services free or nominal fee. Particularly helpful for low-income custodial parents who cannot afford private attorney.
Federal Enforcement Tools
Tax Refund Interception: Federal and state tax refunds intercepted for past-due child support. Automatically applied to arrears. One of most effective tools recovering billions annually. Notice sent to payor before interception. Can contest if not owe or amount incorrect.
Credit Bureau Reporting: Arrears over 1000 dollars or 2 months delinquent reported to major credit bureaus. Damages credit score affecting ability to obtain loans, mortgages, credit cards. Negative marks remain 7 years. Can challenge if information inaccurate.
License Suspension: Driver license suspended for significant arrears. Professional licenses suspended (doctors, lawyers, nurses, contractors). Business licenses. Occupational licenses. Recreational licenses (hunting, fishing). Cannot be renewed until arrears paid or payment plan established.
Passport Denial: Arrears over 2500 dollars triggers passport denial. State Department notified. Cannot obtain or renew passport. Powerful tool for parents attempting to flee country or avoid via international travel.
Other Enforcement Methods
Contempt of Court: Motion for contempt filed. Hearing scheduled requiring payor explain non-payment. Sanctions: jail time up to 6 months per violation, fines, attorney fees, wage garnishment, property liens. Willful non-payment can result in immediate incarceration. Must show ability to pay and willful refusal.
Property Liens and Levies: Judgment liens placed on real property. Prevents sale or refinance until support paid. Bank account levies freeze and seize funds. Vehicle liens. Investment account seizure. Effective when payor has assets but not paying.
Self-Employment and Business Owners
Income Calculation Challenges
Self-employed income harder to determine than W-2 wage earner. Opportunity for manipulation through deductions. Courts scrutinize carefully.
Gross Income Calculation: Start with gross receipts or revenue. Subtract only ordinary and necessary business expenses. Personal expenses claimed as business added back. Examples: personal vehicle use, home office exceeding actual business use, travel mixing business and pleasure, family members on payroll for minimal work, excessive owner compensation.
Depreciation: Non-cash expense often added back to income. Does not represent actual cash outflow. Parent still has use of equipment or property depreciated. Some states allow legitimate depreciation deduction, others add back entirely. Depends on circumstances and state law.
Documentation Required: Minimum 2-3 years tax returns (personal and business). Profit and loss statements. Balance sheets. Bank statements business and personal. General ledger. 1099s and receipts. Credit card statements. Cash flow analysis.
Lifestyle Analysis
When claimed income does not support actual spending, court may conduct lifestyle analysis. Examines: housing costs and mortgage or rent, vehicle expenses, vacations and travel, private school tuition, club memberships, dining and entertainment, purchases and acquisitions. If lifestyle exceeds claimed income, court may impute higher income based on spending patterns. Presumption parent has income to support lifestyle.
Forensic Accountant
For complex self-employment or business ownership, hire forensic accountant. Services: analyze financial records, identify personal expenses claimed as business, calculate actual available income, trace hidden income or assets, prepare detailed income report for court, testify as expert witness. Cost 3000-10000 dollars depending on complexity. Often worth investment when substantial support at stake.
Special Situations
Multiple Families
Parent with children in multiple relationships. How support calculated varies by state. Some states reduce first family support when second family created (low income deviation). Others protect first family support amount. Consider prior support obligations when calculating new order. May impute income for subsequent children born after support order to prevent voluntary reduction of income available for first family.
High-Income Parents
When combined income exceeds state schedule maximum. Methods: extrapolate from schedule using trend, apply discretion based on child needs, use percentage of income above schedule cap, maintain child standard of living. Child support not punitive but ensures child shares in parent prosperity. Reasonable needs of child considered. Lavish lifestyle not required but should approximate marital standard.
Low-Income Parents
When income at or below poverty level. Most states have minimum support amount (often 25-50 dollars monthly). Self-support reserve protects income needed for parent basic needs. Cannot impoverish parent to point of inability to work. May suspend support if parent incarcerated or institutionalized with no income. Can be reinstated when income resumes.
Disability and Benefits
Parent receiving disability benefits. Social Security Disability Income SSDI counts as income. May receive derivative benefits for children automatically reducing support. If child receives benefit on account of parent disability, often credited dollar-for-dollar against support obligation. SSI not counted as income as means-tested. Disability must be verified. Earning capacity still imputed if able to work in some capacity.
Using the Child Support Calculator
Our calculator provides estimates for all 50 states:
Step 1 - Select Your State: Calculator uses state-specific guideline formula. Income Shares, Percentage, or Melson model applied. Critical to choose correct state as formulas vary significantly. Use state where child resides or custody order filed.
Step 2 - Enter Income Information: Both parents gross monthly income from all sources. Include wages, bonuses, self-employment, rental income, investment income, unemployment, disability. Exclude child support received and means-tested benefits like SSI TANF. Use actual current income not historical or projected.
Step 3 - Number of Children: Total children subject to support order. Children from this relationship only not other relationships. Enter 1-6 or more. Percentage increases with each additional child.
Step 4 - Custody and Parenting Time: Primary physical custody arrangement: sole, joint, split. Overnight visits per year with non-custodial parent. Used to determine if shared custody adjustment applies. If exactly 50-50 time specify to calculate offset or credit.
Step 5 - Additional Expenses: Monthly health insurance premium for children. Monthly childcare costs work-related. Extraordinary medical expenses if known. Private school tuition if applicable. Calculator prorates by income share in Income Shares states.
Step 6 - Review Calculation: Calculator shows: base support obligation from state schedule or formula, prorated share for non-custodial parent, add-ons for insurance childcare medical, custody adjustment if applicable, total monthly support payment, annual support amount. High and low estimates if factors create range.
Step 7 - Understand Limitations: Estimates based on guideline calculations. Courts can deviate from guidelines with findings. Special circumstances may increase or decrease. Calculator cannot account for all unique factors. Use estimates for planning and negotiation not definitive orders. Actual order requires court filing or agreement.
How to Reduce Child Support
Increase Parenting Time
Most effective way to reduce support. Increase overnight visits to reach shared custody threshold (typically 25-40 percent depending on state). More time with child reduces custodial parent expenses and increases your direct costs. Must genuinely exercise parenting time, not just claim it. Court examines actual overnight stays not schedule on paper. Provides benefit of more time with child plus support reduction.
Demonstrate Income Reduction
File for modification if income substantially decreased. Job loss, pay cut, hours reduced, business downturn. Must be involuntary and substantial (10-20 percent threshold). Document reason for decrease. Good faith job search efforts. Cannot voluntarily reduce income to avoid support. Burden on payor to prove involuntary change.
Acceptable Income Reductions: Layoff or termination through no fault. Company downsizing or closure. Hours reduced by employer. Documented medical condition preventing full-time work. Retirement at reasonable age after long career. Economic recession affecting industry.
Unacceptable Reductions: Voluntary job change to lower income. Quitting without good reason. Refused promotion or overtime. Career change to pursue passion at lower pay. Early retirement to avoid support. Starting new business with initial low income.
Challenge Imputed Income
If court imputed income higher than actual, challenge with evidence. Show good faith efforts to find higher-paying work. Demonstrate local market conditions limiting opportunities. Provide documentation of applications and interviews. Medical evidence if health limits employment. Vocational evaluation showing realistic earning capacity lower than imputed.
Prove Other Parent Income Increased
If custodial parent income substantially increased, file for modification. In Income Shares states both parents income affects calculation. If recipient now earning significantly more, support obligation may decrease. Burden on payor to prove other parent income and increase. May need discovery including subpoenas, interrogatories, tax returns.
Seek Shared Physical Custody
Move from sole custody to joint physical custody. Requires showing shared custody in child best interest. Benefits child having substantial time with both parents. Reduces support payment through custody adjustment. Must demonstrate ability to co-parent and provide stable environment. Child age and preference if over 12-14 may be considered.
Cost Information
Administrative Process: Through state child support agency: free or minimal fee. Agency establishes and enforces orders. No attorney needed. Best for straightforward cases. Can take longer than court process. Limited ability to negotiate terms.
Uncontested Agreement: Parents agree on support amount and terms. Document in settlement or consent order. Attorney review recommended: 500-1500 dollars. Court filing fees: 50-200 dollars. Total: 500-2000 dollars. Fastest and least expensive approach when parents cooperate.
Mediation: Mediator helps parents negotiate support terms. Cost: 150-400 dollars per hour. Typically 2-4 sessions. Total: 500-3000 dollars split between parents. Much less than litigation. Preserves parental relationship. Still need attorney review of agreement.
Contested Litigation: Attorney representation for disputed support. Cost: 3000-10000 dollars plus per parent. Complex cases with income disputes or business valuations: 8000-25000 dollars plus. Includes discovery, financial analysis, court hearings, trial if necessary. Expert witnesses (forensic accountants, vocational evaluators) add substantial cost.
Modification Costs: Agreed modification: 500-1500 dollars. Contested modification: 2000-8000 dollars per parent. Less than initial determination but still significant. Filing fees, updated financial disclosures, possible hearing. Can use state agency for enforcement modifications often free.
Divorce.com Packages: Child support included in divorce services. Paperwork Only 499 dollars includes child support worksheet and documents. We File For You 999 dollars includes filing support order with court. Fully Guided 1999 dollars includes mediation to resolve support disputes.

Frequently Asked Questions
Q: How is child support calculated? A: Depends on state model. Income Shares (41 states) combines both parents income finds base from schedule prorates by income percentage. Percentage of Obligor Income (7 states) applies percentage 20-40 percent to non-custodial parent income based on number of children. Melson Formula (3 states) uses three-tier approach ensuring self-support reserves then child needs.
