Indiana Child Support Calculator

Indiana uses the income shares model under the Indiana Child Support Guidelines. Both parents' weekly gross incomes are combined to determine a basic support obligation from a schedule. That obligation is then split proportionally based on each parent's share of the combined income. The non-custodial parent typically pays their share to the custodial parent, with adjustments for parenting time, childcare costs, and health insurance.

Gross income in Indiana includes all income from any source: wages, salary, bonuses, commissions, overtime, self-employment income, pensions, Social Security, unemployment benefits, disability payments, rental income, and investment income. Certain deductions are allowed, such as support obligations for other children, but the calculation starts with gross income before taxes.

Indiana provides a parenting time credit when the non-custodial parent has 52 or more overnight visits per year. For 52-142 overnights, a 6% credit is applied to the basic obligation, reducing the support amount. For 143 or more overnights (approximately equal parenting time), an adjusted offset calculation is used where each parent's obligation is compared and the difference is paid by the higher-earning parent.

Yes, either parent can petition for a modification if there has been a substantial and continuing change in circumstances. Common reasons include significant income changes, job loss, changes in parenting time, changes in the child's needs, or changes in childcare or healthcare costs. Indiana also allows review if the current order differs from the guidelines by 20% or more.

In Indiana, child support generally continues until the child turns 19. However, it may end at 18 if the child is emancipated, married, or joins the military. Support may also continue past 19 if the child has a disability. Indiana courts can also order educational support for college expenses under certain circumstances.

Indiana child support guidelines use weekly gross income as the basis for calculations. If you receive a monthly salary, divide by 4.33 to get your weekly gross income. If you are paid biweekly, divide your biweekly gross pay by 2. The support obligation is calculated weekly and then converted to a monthly or biweekly payment schedule for the support order.

This calculator provides an estimate based on the Indiana income shares model. Actual child support orders may differ because courts also consider childcare expenses, health insurance costs for the child, extraordinary medical expenses, educational expenses, and other relevant factors. The court has discretion to deviate from the guidelines when appropriate. Always consult with a family law attorney for an accurate assessment.
