Alimony Child Support in Iowa

Iowa law sets child support and spousal support (alimony) using separate statutes with distinct rules. Child support under Iowa Code § 598.21B applies a guideline formula based on each parent’s income and custodial time, with a statutory annual adjustment of 6% applied to the support amount. Spousal support under § 598.21A is determined by a court considering statutory factors, without a fixed formula or automatic 6% adjustment. The official source for child support guidelines is the linked PDF. For a precise estimate, the DocketMath calculator applies the code’s rules to your specific income and custody arrangement, avoiding the need to manually reconstruct the formula. Consult the official source for exceptions and details.
