How Indiana Child Support Is Calculated

Indiana child support follows the Income Shares Model established by the Indiana Supreme Court Child Support Guidelines. The calculations operate primarily on Weekly Gross Income amounts, converting weekly schedule figures into monthly transfer obligations.

Step-by-Step Calculation Breakdown ($5,000 vs $3,000 Monthly Gross, 2 Children, 96 Overnights)
Step 1: Convert Monthly Incomes to Weekly Amounts & Shares
• Parent 1 Weekly Income: $5,000 ÷ 4.333 = $1,154 / week
• Parent 2 Weekly Income: $3,000 ÷ 4.333 = $692 / week
• Combined Weekly Gross: $1,846 / week
• Parent 1 Share: $1,154 ÷ $1,846 = 62.5%
Step 2: Lookup Basic Weekly Obligation & Add-On Expenses
• Indiana Basic Weekly Obligation (2 Children on $1,846/wk): $295 / week ($1,278/mo)
• Parent 1 Base Pro-Rata Share (62.5%): $1,278 × 62.5% = $799 / month
• Healthcare ($120) + Childcare ($250) Add-On Share (62.5%): +$231 / month
Step 3: Apply Indiana Parenting Time Credit & Calculate Final Transfer
• 96 Overnights = 21.0% Parenting Time Credit Reduction
• Monthly Parenting Time Credit: $1,278 × 21.0% = -$268 / month
• Less Direct Insurance/Childcare Paid: -$370
Estimated Net Monthly Child Support Transfer: $392 / month

Frequently Asked Questions

How does the Indiana Income Shares Model work?
Indiana uses the Income Shares Model codified by the Indiana Supreme Court. Calculations start on a weekly basis, combining both parents' weekly gross incomes to lookup the basic child support obligation, which is then divided proportionally based on income share.
How does the Indiana Parenting Time Credit reduce support?
Under Indiana Child Support Guideline 6, the non-custodial parent earns a Parenting Time Credit based on annual overnights (from 52 overnights up to 183 overnights). The percentage credit offsets the weekly basic child support obligation.
What counts as weekly gross income in Indiana?
Indiana includes all actual weekly income: salaries, overtime, bonuses, tips, self-employment profits, pensions, disability benefits, and investment returns, less self-employment taxes and prior legal child support obligations.
How are childcare and health insurance apportioned in Indiana?
Work-related childcare costs and the child's portion of health insurance premiums are added directly to the basic weekly obligation and shared according to each parent's weekly percentage share.
At what age does child support terminate in Indiana?
In Indiana, child support generally terminates when the child turns 19 years old (unless the child is emancipated earlier or incapacitated). Note that educational support for post-secondary college expenses can be petitioned separately.
