How Iowa Calculates Child Support

Iowa calculates child support using the Income Shares Model as defined in Iowa Code §598.21B. Both parents' gross incomes are combined to determine the total support obligation from the state schedule, then each parent's share is allocated proportionally based on their percentage of the combined income. The model estimates the amount of support that would have been available to the child if the parents had remained together.

The calculation begins by determining each parent's gross monthly income from all sources. These incomes are combined, and the state schedule is used to find the basic support obligation for the number of children involved. Health insurance premiums and childcare costs are added to the base obligation, and adjustments are made for shared physical care arrangements, extraordinary visitation credits, and the self-support reserve of $1,100 per month.

Iowa is notable for allowing courts to order college expense contributions through age 22. Courts may deviate from guideline amounts when justified by the specific circumstances of the case, including the child's special needs or extraordinary expenses.
