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 2024. 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.

How Child Support is Calculated in Idaho


Child support payments in Idaho are calculated using the income shares category method. Payments depend on the combined incomes of the parents as well as the number of children. A larger combined income or more children usually means greater payments.

The amount paid or received by an individual parent also depends on their income percentage. The higher your percentage of combined parent income, the more you pay or less you receive.

Payments are also affected by which parenting time category applies. Payments may be lower because of a "shared" (fairly equal) care arrangement.

Idahoans paying the most child support have high incomes and limited parenting time. Conversely, the biggest receivers are parents who (a) work little (b) have their kids most of the time and (c) have a high earner as the other parent.

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.
