How this calculator works

Indiana calculates child support using the income shares model under the Indiana Child Support Rules and Guidelines, adopted by the Indiana Supreme Courtsource verified 2026-07-21. Unlike most other states, Indiana's guideline runs entirely in weekly gross income, not monthly or annual. The state estimates what two parents would have spent on their child if they lived together, then splits that amount between them in proportion to each parent's income.

Step by step

1. Start with each parent's weekly gross income from nearly all sources (Guideline 3A).

2. Add both incomes to get combined weekly adjusted income, then look up the Basic Child Support Obligation on the official Guideline Schedules for Weekly Support Payments, which runs from $100 to $9,200 in $10 steps for one to eight children (Guideline 3D). Above $9,200, the guidelines switch to a fixed percentage of combined income.

3. Add each parent's share of work-related child care and the children's health insurance premium to reach the Total Child Support Obligation (Guideline 3E).

4. Divide that total between the parents in proportion to their income share (Guideline 3F).

5. Apply the Parenting Time Credit: using the official Parenting Time Table, the noncustodial parent's obligation is reduced by a percentage of the Basic Child Support Obligation that grows with the number of overnights, from 52 overnights a year up to 183 (equal time) (Guideline 6).

Worked example — Two children, noncustodial parent earns $800/week, custodial parent earns $500/week (combined $1,300/week), $60/week child care and $20/week health insurance currently paid by the custodial parent, noncustodial parent has 100 overnights a year.

Combined weekly adjusted income: $1,300. The schedule's Basic Child Support Obligation for two children at $1,300 is $333/week. Adding $60 child care and $20 health insurance gives a Total Obligation of $413/week. The noncustodial parent earns 61.5% of the combined income, so their share is $254.15/week. At 100 overnights, the Parenting Time Table gives a 25.3% credit on the $333 basic obligation — a $84.25/week reduction. The estimated order is about $170/week, or roughly $736.67/month.

Why Indiana works in weekly income

Most states run their child support worksheets on monthly or annual income, which can make Indiana figures look unfamiliar at first. The state's own Guideline Schedules for Weekly Support Payments and Child Support Obligation Worksheet are built entirely around weekly gross income (Guideline 1). This calculator keeps that weekly basis to match what a court will actually use, and shows an approximate monthly figure (weekly × 52 ÷ 12) only for convenience.

Estimation limits

  • This tool reads the official schedule at the nearest $10 income bracket, the method the guidelines direct (Guideline 3D) — results are estimates, not a court order.
  • It does not apply the income adjustments for subsequent-born children (Guideline 3C.1) or spousal maintenance paid (Guideline 3C.4), or any credit for a prior-born child (Guideline 3C.2–3).
  • It does not model imputed or potential income for an unemployed or underemployed parent, split custody (two-worksheet method), different overnight counts for different children, Social Security benefit credits, or discretionary deviations.
  • For equal parenting time (181–183 overnights), the court must also designate which parent pays the "controlled expenses" (clothing, school costs); this tool calculates the parenting time credit but does not resolve that designation.
  • Above the schedule maximum ($9,200 combined weekly income), the guidelines apply a fixed percentage of income rather than a table lookup; this tool applies that percentage rule automatically.

Frequently asked questions

How is child support calculated in Indiana?

Indiana uses an income shares model based on weekly gross income: you add both parents' weekly gross incomes, look up the basic obligation for that combined income and number of children on the official Guideline Schedules for Weekly Support Payments, and split it in proportion to each parent's income — with credits for parenting time, child care, and health insurance.

Why does Indiana use weekly income instead of monthly or annual?

Indiana's guideline schedule and Child Support Obligation Worksheet are built entirely around weekly gross income. This calculator works in weekly figures to match the official worksheet, and also shows an approximate monthly equivalent for comparison with other states.

How many overnights do you need for a parenting time credit in Indiana?

The Parenting Time Table begins at 52 overnights a year (roughly alternate weekends). Below that, no credit applies. The credit grows steadily from 52 overnights up to 183 overnights (equal parenting time).

How is child support calculated with 50/50 custody in Indiana?

Equal parenting time (181 to 183 overnights a year) still uses the same worksheet and the top of the Parenting Time Table. The court must also decide which parent pays the "controlled expenses" (like clothing and school costs); that parent does not receive the parenting time credit.

What counts as income for Indiana child support?

Weekly gross income from nearly all sources — wages, salaries, commissions, bonuses, self-employment (gross receipts minus reasonable expenses), pensions, Social Security, unemployment, and more. Means-tested benefits like TANF, SSI, and food stamps are excluded (Guideline 3A).

Is there a minimum or maximum in the Indiana schedule?

The published schedule runs from $100 to $9,200 in combined weekly adjusted income. Above $9,200, the guidelines apply a fixed percentage of combined income instead of a table lookup — from 8.1% for one child up to 20.4% for eight children.

Does Indiana child support include health insurance?

Yes. The weekly cost of the children's portion of health insurance premiums is added to the basic obligation and shared between the parents, and the parent who actually pays it receives a credit (Guideline 3E, 7).

When does child support end in Indiana?

Generally when the child turns 19, Indiana's statutory age of emancipation (IC 31-16-6-6). It can end earlier for marriage, military service, or self-support, or continue longer for a child still in high school or with a disability.

What if a parent is unemployed or underemployed?

A court can impute potential income based on that parent's work history, education, and local job opportunities if the unemployment or underemployment is voluntary and without just cause (Guideline 3A.3). This calculator does not model potential income — enter actual current income.

Is this an official Indiana child support calculation?

No. It's an educational estimate using the state's guideline method. Indiana's own online calculator and the Child Support Obligation Worksheet, filed with the court, produce the binding figure, and a judge may deviate from the guideline amount.
