Courts use the guidelines in the Child Support Percentage of Income Standard for setting child support payment amounts. The guidelines are based on the belief that both parents are responsible for supporting their children, whether they live together or not.

Only a court may change the ordered payment amount. Your child support agency might be able to help.

The following are guidelines and resources for calculating child support payment amounts:

• Guidelines for Setting Child Support Payment Amounts 
• Tables to estimate child support amounts: Low-Income Payer Table 
• Calculators to estimate support amount:
  • Shared-Placement Support Calculator - Estimates support payments in shared-placement cases
  • High-Income Payer Support Calculator - Estimates support payments if the payer's income is over $7,000 per month ($84,000 per year)
• Administrative Rule DCF 150:
  • DCF 150 Worksheet - Estimates income for child support when the parent is self-employed
