Child support for two children has no fixed amount — it depends on your state's formula, both parents' income, custody arrangement, and other factors like health insurance costs.
There is no national child support table. Each state writes its own formula, and most use income shares — a method that divides the cost of raising children based on what each parent earns. A parent in California with two children and $60,000 annual income will owe a different amount than a parent in Texas with the same income, because the formulas differ.
The paying parent (called the obligor) typically owes a percentage of their gross income, but the exact percentage varies by state and by the number of children. States also adjust for custody time, existing child support obligations, and sometimes childcare or health insurance costs. A court order sets the amount, not a calculator or website.
Key Takeaways
- Each state has its own child support formula, so the amount owed for two children depends on which state issued the order.
- Most states use income shares, meaning the obligor pays a percentage of gross income that increases with the number of children.
- The court considers both parents' income, custody time, and sometimes childcare or insurance costs when setting the amount.
- A family court judge or administrative hearing officer enters the order; you cannot calculate it yourself without knowing your state's exact formula and both parents' full financial details.
How states calculate child support for two children
The income shares model is used by most states. Under this method, the court adds both parents' gross income, looks up what percentage of that combined income is needed to support two children (this percentage is set by state law), and then divides that obligation between the parents based on their individual income shares.
For example, if Parent A earns $50,000 and Parent B earns $30,000, their combined income is $80,000. If the state says 25% of combined income supports two children, the total obligation is $20,000 per year. Parent A earns 62.5% of the combined income, so Parent A pays 62.5% of the $20,000 obligation — roughly $12,500 per year or about $1,042 per month. Parent B pays the remaining 37.5%, or about $625 per month. However, if Parent B has primary custody, Parent A's payment is adjusted upward because Parent A is not providing direct support through housing and food.
Some states use a flat percentage model instead, where the obligor simply pays a set percentage of gross income for two children — often between 20% and 30% depending on the state. This method is simpler but does not account for the other parent's income.
Income and custody factors that change the amount
The obligor's gross income is the starting point, but "gross income" is defined differently by each state. Most include wages, salary, self-employment income, rental income, and sometimes bonuses or commissions. Some states include unemployment benefits or disability payments; others do not. A parent who is self-employed or has irregular income may face a different calculation than a salaried employee.
Custody time directly affects the amount owed. If both parents share custody roughly equally, the obligor's payment is lower than if the other parent has primary custody. A parent with 50% custody pays less than a parent with 20% custody, because the obligor is providing direct support during their parenting time. The court uses the actual custody order or, if no order exists, the arrangement the parents report.
Other adjustments include existing child support obligations to other children (which reduce the current obligation), childcare costs paid by the obligor, health insurance premiums the obligor pays for the children, and sometimes extraordinary medical or educational expenses. A few states also consider the standard of living the children would have had if the parents remained together, though this is less common.
What "gross income" includes and excludes
Gross income for child support purposes is not the same as taxable income. It typically includes all earned and unearned income before taxes and deductions. Wages, salary, bonuses, commissions, self-employment income, rental income, interest, dividends, and pension or retirement distributions usually count.
What is usually excluded: income-based tax credits (like the Earned Income Tax Credit), means-tested benefits (like SNAP or TANF), child support received from another obligor, and sometimes spousal support received. Some states exclude workers' compensation or disability benefits; others include them. If a parent is deliberately underemployed — earning less than they could — some states will "impute" income, meaning the court assigns an income level based on what the parent could earn, not what they actually earn.
Self-employed parents must provide tax returns, profit-and-loss statements, and sometimes bank records to prove income. A parent who claims low income must document it; the court will not simply accept their word.
How to find your state's specific formula and amounts
Your state's child support guidelines are published in statute or regulation and are usually available on your state's child support enforcement website or family court website. Search "[your state] child support guidelines" or "[your state] income shares model" to find the official percentage or formula.
Many states publish a child support table that shows the base obligation for different income levels and numbers of children. For example, a state might publish a table showing that for combined parental income of $80,000 and two children, the base obligation is $1,600 per month. You can then look up your combined income and number of children to see the ballpark figure, though the actual order will account for custody, insurance, and other factors.
If you are in a court case, the judge or hearing officer will calculate the amount using the state formula and enter it in the order. If you are negotiating with the other parent outside court, you can use your state's published guidelines to estimate what a court would order, then agree to that amount or negotiate from there. Some states offer free online calculators on their child support enforcement website, though these are estimates only and do not replace a court order.
Modifications when income or custody changes
A child support order is not permanent. If either parent's income changes significantly — a job loss, a major raise, a career change — or if custody changes, the obligor can request a modification. Most states allow a modification if income has changed by 10% or more, or if there has been a substantial change in custody.
The parent requesting the change must file a motion with the court that issued the original order and provide documentation of the income change or custody change. The court will recalculate using the new figures and issue a new order. Until the new order is entered, the old amount is still owed. A parent cannot simply stop paying because they believe they should owe less.
Modifications are common when a parent loses a job, receives a promotion, retires, or when custody shifts — for example, if the children move in with the obligor. The process varies by state but typically takes a few weeks to a few months.
Frequently Asked Questions
Is there a standard amount for two kids across all states?
No. Each state has its own formula and percentages. A parent owing child support for two children in one state may owe significantly more or less in another state with the same income. The only way to know the amount is to look up your specific state's guidelines or have a court order entered.
Does the obligor's new spouse's income count toward child support?
Generally no. The new spouse's income is not included in the obligor's income calculation. However, if the new spouse's income allows the obligor to reduce their own work hours or spend money differently, a court may consider that in a modification case. The focus is on the obligor's own income.
What if the obligor is unemployed or disabled?
If a parent is truly unable to work, the court may impute income based on their earning capacity or may set a minimal obligation. However, courts are skeptical of claims of unemployment and often impute income based on the parent's education, work history, and local job market. A parent cannot simply claim zero income and owe nothing.
Can child support be modified if the obligor's income goes down?
Yes, if the income decrease is substantial and documented. The obligor must file a modification request with the court and provide proof of the income change — pay stubs, tax returns, or a termination letter. The court will recalculate and may lower the obligation, but the obligor still owes the old amount until a new order is signed.
Do both parents' incomes affect the amount owed?
Yes, in income shares states. Both parents' income is added together to calculate the base obligation, then divided between them based on their income percentage and custody time. In flat percentage states, only the obligor's income matters. Your state's formula determines which applies.
