How Indiana calculates child support
Indiana's Supreme Court sets child support guidelines that work in weekly amounts. The court adds both parents' weekly adjusted income, finds the basic child support obligation in the Guideline Schedules, adds work-related child care and the children's health insurance premium, and splits the total by each parent's share of the combined income (Guidelines 3D to 3F).
The noncustodial parent pays their share, minus credits for child care or premiums they pay directly and a parenting time credit for overnights with them (Guideline 6). The steps follow the state's Child Support Obligation Worksheet.
| 1. Weekly income | Each parent's weekly gross income, less any support ordered for children born earlier, maintenance paid, and a credit for children born later (Guideline 3C). The calculator starts from gross income. |
|---|---|
| 2. Schedule amount | The combined weekly income, rounded to the nearest amount in the schedule, and the number of children (1 to 8). |
| 3. Add costs | Work-related child care and the children's part of the health insurance premium. |
| 4. Split by income | The noncustodial parent's percentage of combined income × the total. |
| 5. Credits | Child care and premiums the noncustodial parent pays, and the parenting time credit from Table PT. |
Example: $600 and $850 a week, three children
This family comes from the Guidelines' own parenting time example (Guideline 6 Commentary): the noncustodial parent earns $600 a week and the custodial parent $850. Here the children spend 120 nights a year with the noncustodial parent.
| Combined weekly income: $600 + $850 | $1,450 |
|---|---|
| Schedule amount, three children | $444.00 |
| Noncustodial share: $600 ÷ $1,450 = 41.38% × $444 | $183.73 |
| Parenting time credit, 120 nights: $444 × 0.438 − 41.38% × ($444 × 0.324) | −$134.94 |
| Weekly child support | $48.79 |
The Guidelines' example gives the same credits: $28.95 at 56 nights, $134.94 at 120 nights and $206.95 at 180 nights. Choose "Week" in the calculator and enter $600, $850, three children and the nights to see them.
Parenting time and equal time
The parenting time credit starts at 52 overnights a year and grows with more nights. It reflects that the noncustodial parent pays some costs directly during their time, and that some costs, like housing, are duplicated in both homes.
Time is "equally shared" at 181 to 183 overnights each. Then one parent is designated to pay the controlled expenses, such as clothing and school supplies, and the other parent gets the credit. When the custodial parent earns much more, the credit can mean that parent pays support to the other (Guideline 3F commentary).
| 0 to 51 nights | No credit, though a court may give one, for example for an infant or long distance. |
|---|---|
| 52 to 183 nights | Credit = schedule amount × the TOTAL factor − the parent's share × schedule amount × the DUPLICATED factor, from Table PT. |
| Not automatic | The court decides whether the credit would jeopardize a parent's ability to support the children. |
Questions people ask
How is child support calculated in Indiana?
Add both parents' weekly adjusted income and find the basic obligation for that amount and the number of children in the Guideline Schedules for Weekly Support Payments. Add work-related child care and the children's health insurance premium. The noncustodial parent owes their percentage share of the total, minus credits for costs they pay directly and a parenting time credit for overnights with them.
Is Indiana child support weekly or monthly?
The Indiana guidelines and the schedule use weekly amounts, so orders are usually stated per week. The calculator shows the weekly amount and an approximate monthly figure (weekly × 52 ÷ 12).
When did the Indiana guidelines last change?
The current guidelines and weekly schedule took effect January 1, 2024. The Guidelines' commentary says the schedule was changed then to reflect more recent estimates at all levels of income, and the old "6% rule" for uninsured health care costs was dropped; those costs are now shared in proportion to income (Guideline 7).
What is the parenting time credit?
A reduction in the noncustodial parent's support for overnights the children spend with them, starting at 52 a year. It is figured from Table PT in Guideline 6, using a TOTAL factor and a DUPLICATED factor for the number of overnights. The court can decline to apply it if it would leave a parent unable to support the children.
Is there a minimum child support amount in Indiana?
No set minimum. The guidelines say a numeric amount should be ordered, but the court must make sure the paying parent keeps enough for a minimum subsistence level, and a $0 order can be appropriate in some situations (Guideline 2). Below $100 a week of combined income, support is set case by case.
