Talk to AI AdvisorHow Child Support Is Calculated
Most states, including Indiana, use an income-shares model that considers both parents' incomes to determine how much the child would have received in an intact household.
Both parents' gross income
Wages, salaries, bonuses, commissions, self-employment income, investment income, and sometimes imputed income if a parent is voluntarily underemployed.
Number of children
More children = higher support, but not proportionally. The per-child amount decreases slightly with each additional child.
Custody arrangement
The more overnights the paying parent has, the lower the support amount. 50/50 custody typically reduces the obligation significantly.
Healthcare and childcare costs
Health insurance premiums, uninsured medical expenses, and work-related childcare costs are typically added to the base amount.
What Child Support Covers
- ✓Housing (rent/mortgage contribution for the child's home)
- ✓Food, clothing, and basic necessities
- ✓Education expenses (school supplies, tuition in some cases)
- ✓Healthcare premiums and medical expenses
- ✓Transportation costs
- ✓Extracurricular activities (may be shared separately)
When Child Support Ends
- ✓Child turns 18 (or 19 if still in high school in some states)
- ✓Child becomes emancipated (joins military, gets married, becomes self-supporting)
- ✓Parental rights are terminated
- ✓Court modifies the order based on changed circumstances
Modifying Child Support in Indiana
Either parent can request a modification when there's a significant change in circumstances: job loss, major income increase, change in custody arrangement, or a child's special needs. You'll need to file a motion with the court — don't just stop paying or informally agree to a different amount.
