Calculating Debt Payoff
If you have unpaid child support debt, you can figure out how long it will take to pay it off with our Arrears Payoff Calculator.
You can choose a payment and see how many months it will take until you’re paid in full, or choose a time frame and it will show you the payment you need to make to have a zero balance by the end date.
The California Child Support Guideline Calculator is based on the same child support legal guidelines used in California courts, and can be used to estimate the amount of child support that may be ordered in your case.
The county child support commissioner or family law judge has the final authority to determine the amount of a child support order. This calculator provides only an estimate and is not a guarantee of the amount of child support that will be ordered. Many factors may affect the amount of child support awarded.
If you have any questions about the child support guidelines, you should talk with a lawyer or contact a Family Law Facilitator.
