Idaho Child Support Calculator

Simple Child Support Calculator

For a simple and easy calculation of child support in Idaho, we suggest trying the ChildSupportNet calculator. Idaho appears to lack an official, government calculator that is easy to use.

The ChildSupportNet calculator is quite simple and easy to use. But note that the estimator may not always be accurate and up to date for 2021. For a more reliable assessment, you can try the official version.

In the state of Idaho, the result of an online calculation should be interpreted carefully. You should treat the estimate as just a preliminary indication of the child support amount you could receive or be required to pay.

Idaho Parenting Time Calculator

While Idaho child support guidelines focus on which parent is the "custodial parent", parenting time shares have the potential to affect child support. Actual parenting time percentages could influence the order a judge makes or how much parents agree to.

Use this overnights calculator to work out your parenting time percentage. Most states measure parenting time based on overnight stays.

How Child Support is Calculated in Idaho


Child support payments in Idaho are calculated using the income percentage method. Payments are calculated as a fraction of the non-custodial parent’s income. The more children involved, the higher amount that will generally have to be paid.

Idahoans paying the most child support have high incomes and multiple children. The biggest recipients of child support are parents with primary care of multiple children where the paying parent has a high income.

The Idaho child support calculator may be reliable for a parent who is giving child support. But you have to reveal your financial details to determine how much you can afford for child support. Gross salary and how many children receive child support will determine how much you have to contribute.

Child support is based upon factors which include each parents’ income; the number of overnights each parent has with the child; which parent is paying for health insurance; the age of the child; and whether there are other children in the home who are not the offspring of the divorcing parents. In some instances, support orders can deviate from the standard calculation.
