Child Support in Indiana: How It's Calculated
Indiana uses the Income Shares Model to determine child support obligations. This guide walks through how the formula works, what factors Indiana courts consider, and how to modify or enforce an order — with links to official Indiana resources.
Income Shares Model in Indiana
Indiana uses the Income Shares Model under the Indiana Child Support Guidelines. Support is calculated based on the combined weekly gross income of both parents — Indiana uses weekly income (annual income divided by 52) rather than monthly. The resulting obligation is divided proportionally.
Indiana has a tiered parenting time credit system: non-custodial parents who exercise more than 52 overnights per year receive a 15% reduction; more than 127 overnights receive a 30% reduction; and 182+ overnights (near 50/50) receive a 40% reduction. Indiana's guidelines specify minimum support amounts even for very low incomes.
Key Factors Indiana Courts Consider
- Both parents' weekly gross income (annual income ÷ 52)
- Number of children
- Overnights exercised by non-custodial parent — triggers tiered credit reductions at 52, 127, and 182 overnights
- Child's health insurance premium
- Work-related childcare expenses
- Prior support obligations for other children
- Any extraordinary expenses for the child

Step-by-Step: How Indiana's Formula Works
Here is how Indiana applies the Income Shares Model to calculate a child support obligation, step by step:
1. Determine each parent's income
Indiana starts by calculating each parent's income — gross income (before taxes). The specific definition of income is set by Income Shares Model.
2. Combine incomes and find the basic obligation
Both parents' incomes are combined and compared to Indiana's child support schedule. The schedule produces a basic child support obligation based on combined income and the number of children.
3. Add health insurance and childcare costs
Health insurance premiums paid for the child and work-related childcare expenses are added to the basic obligation before it is divided between parents.
4. Divide proportionally based on income share
The total obligation is allocated between the parents in proportion to each parent's share of combined income. The parent with the higher income share bears a larger portion of the obligation.
5. Apply parenting time credits
Overnights exercised by non-custodial parent — triggers tiered credit reductions at 52, 127, and 182 overnights parenting time credit system: non-custodial parents who exercise more than 52 overnights per year receive a 15% reduction; more than 127 overnights receive a 30% reduction; and 182+ overnights (near 50/50) receive a 40% reduction.
