What You Need Before Estimating Child Support
Gathering four basic pieces of financial information will ensure your estimate is as close to an official court worksheet as possible.
Gross or Net Monthly Incomes
Recent pay stubs, W-2 forms, or self-employment profit-and-loss statements for both parents. Our state calculators specify whether your jurisdiction uses gross or net income.
Annual Parenting Overnights
The number of overnight stays the children spend in each household annually. States apply major credit adjustments once specific overnight thresholds are met.
Healthcare & Childcare Premiums
The monthly incremental cost to add children to employer health insurance, plus out-of-pocket work-related childcare or daycare tuition.

Frequently Asked Questions About Child Support
Answers to common questions regarding calculation rules, court enforcement, and online estimates.
Is this an official government child support calculator?
No. This website is an independent educational and computational utility. We are not a government agency, court system, or law firm. However, our engines are programmed to replicate the official statutory formulas and economic schedule tables enacted in each state's statutes.
Does 50/50 equal custody mean no child support is owed?
In almost all cases, no. While equal physical custody reduces the transfer amount, if one parent earns more than the other, the higher-earning parent is still ordered to pay child support under state cross-credit guidelines to maintain balanced living standards across both households.
Is child support taxable or tax-deductible?
Under federal IRS rules (IRC § 71 and § 215), child support is completely tax-neutral. Payments are neither tax-deductible for the paying parent nor countable as taxable income for the recipient parent.
Can parents privately agree to waive child support?
No. In U.S. family law, child support is the legal right of the child, not the parent. Family court judges will not enforce a private agreement or waiver unless parents submit an approved calculation showing that the child's financial needs are fully met.
