Idaho Child Support Calculator | Guidelines

The Idaho Child Support calculator is based on the Idaho Child Support Guidelines. The Guidelines set forth the method of calculating child support requirements for each child and they are based on a number of factors including each parent’s income, costs and other adjustments. The amount you come up with using these guidelines is an estimate only and may differ from an actual child support order due to other factors that a court may take into account.
