Maximum Child Support Payment Calculator
Find out the maximum child support you could be ordered to pay, including federal CCPA garnishment limits, state guideline caps, and how courts handle high-income cases above the formula.
Federal Consumer Credit Protection Act Limits
The Consumer Credit Protection Act (CCPA) sets the federal ceiling on how much of your disposable income can be garnished for child support through wage withholding. These limits apply to the enforcement mechanism, not to the court order itself. A judge can order any amount, but wage garnishment to collect that amount is federally capped.
The CCPA establishes four tiers. If you are currently supporting another spouse or child, the limit is 50% of disposable income. If you are supporting another family and are also 12 or more weeks behind on payments, the limit increases to 55%. If you are not supporting another family, the limit is 60%. And if you are single (not supporting another family) and 12 or more weeks in arrears, the maximum garnishment is 65% of disposable income.
Disposable income for CCPA purposes means gross income minus mandatory deductions: federal, state, and local taxes, Social Security, Medicare, and mandatory retirement contributions. Voluntary deductions like 401(k) contributions, union dues, or health insurance premiums are generally not subtracted.
State Guideline Income Caps
Every state's child support formula has an income level above which the standard formula no longer applies. This is the guideline income cap. Texas caps at net resources of $9,200 per month ($110,400/year). New York's cap is $203,000 in combined parental income. California caps at approximately $360,000. Illinois extends to $500,000.
Above the cap, the formula stops producing a number, and the court must exercise discretion. This does not mean support is capped at the formula amount. Courts regularly order above-guideline support for high-income families based on the child's established standard of living, actual needs, and the paying parent's ability to pay. The cap is where the formula ends, not where the obligation ends.
For parents with income above the state cap, the high-income child support calculator provides a more detailed analysis of the range of possible outcomes.
Difference Between Formula Caps and Court-Ordered Caps
There is an important distinction between what the formula can calculate and what a court can order. The guideline cap limits the formula. The CCPA limits wage garnishment. But the actual court order can exceed both. A court can order $10,000 per month in support even if the guideline formula only produces $5,000 and even if CCPA limits garnishment to $8,000.
When the court order exceeds the CCPA garnishment limit, the difference must be collected through other enforcement methods: asset seizure, contempt proceedings, license suspension, tax refund intercepts, or voluntary payment. This is most common in high-income cases where guideline support is a small fraction of the obligor's total resources.
In high-profile cases, courts have ordered support payments reaching tens of thousands of dollars per month. These extreme amounts reflect the principle that a child is entitled to share in a parent's high standard of living, regardless of what percentage of income that represents.
What Percentage of Income Is Typical?
For most families, child support falls between 15-30% of the obligor's gross income. The percentage varies by the number of children: roughly 17-20% for one child, 25-28% for two children, and 30-35% for three or more children. These percentages decrease as income increases because children's basic needs do not scale linearly with parental income.
At very high incomes, the percentage often drops to 10-15% of gross income even though the dollar amount is substantial. A parent earning $1 million per year might pay $8,000-$12,000 per month (10-15%) rather than $15,000-$20,000 (18-24%). Courts recognize that at a certain point, additional dollars do not proportionally benefit the child and may instead constitute an indirect wealth transfer to the custodial parent.
Frequently Asked Questions
What's the most child support can be?
There is no absolute dollar ceiling. The practical maximum is constrained by the CCPA garnishment limits (50-65% of disposable income for wage withholding) and the court's assessment of the child's reasonable needs. For most families, support ranges from 15-30% of gross income. In high-income cases, courts have ordered payments exceeding $50,000 per month when the obligor's income justified it.
Can I pay more than 50% of my income?
A court order can technically require more than 50% of your income, but wage garnishment is capped by the CCPA at 50-65% of disposable income depending on your circumstances. If the court orders more than can be garnished, you would need to pay the remainder through other means. This situation is uncommon for average-income families but occurs in high-income or arrears cases.
What are CCPA garnishment limits?
The Consumer Credit Protection Act limits child support wage garnishment to: 50% of disposable income if supporting another family, 55% with another family and arrears, 60% if not supporting another family, and 65% single with arrears. Disposable income is gross pay minus mandatory deductions (taxes, Social Security, Medicare). Voluntary deductions are generally not subtracted.
