Updated for 2026 guidelines
Indiana Child Support Calculator 2026
Indiana does something almost no other state does: the whole child support worksheet runs in dollars per week. Income, schedule, credit, order, all weekly. This page runs that arithmetic the way the Guidelines write it, including the parenting time credit bands, and shows the monthly equivalent beside the weekly order.

Estimate Indiana child support (weekly)
Estimated child support (monthly equivalent of the weekly order): $576.94
The paying parent pays this amount to the receiving parent each month.
Assumptions
- Indiana computes child support in WEEKLY dollars: incomes, the schedules, and the order are all per-week figures (Guideline 3). The monthly figure shown is weekly times 52 divided by 12, for comparison with other states only.
- Weekly gross incomes are taken as given; potential-income findings for unemployed or underemployed parents and in-kind benefit valuation (Guideline 3A) are court determinations this tool does not make.
- Guideline 9 lets a court round the order to the nearest whole dollar; this tool keeps cents so the arithmetic stays visible.
- The guideline amount is a rebuttable presumption (Support Rule 2); a court may deviate with written findings (Support Rule 3), and child support plus temporary maintenance together may not exceed 50 percent of the paying parent weekly adjusted income (Guideline 2).

How the Indiana guidelines work
Indiana child support comes from the Indiana Child Support Rules and Guidelines, adopted by the Indiana Supreme Court as court rules rather than a statute. The model is income shares: each parent starts with weekly gross income from any source, subtracts a few specific items to reach weekly adjusted income, and the two adjusted figures are combined. The combined number is looked up on the Guideline Schedules for Weekly Support Payments, and each parent covers a slice of that basic obligation in proportion to income. The guideline amount is a rebuttable presumption; a judge who departs from it must explain why in writing.
The weekly basis is not a display choice. The schedules themselves run from $100 to $9,200 of combined weekly adjusted income in $10 steps, with columns for one through eight children. An Indiana order is set in dollars per week, and the official worksheet never mentions a month. If your pay is monthly, multiply by 12 and divide by 52 to get the weekly figure the worksheet wants.
Between those $10 rows, Indiana rounds to the NEAREST schedule amount. That is its own rule: Maryland jumps up to the next higher row, Colorado interpolates, Indiana snaps to whichever row is closer. Above $9,200 a week the schedule does not simply stop. It adds a marginal percentage of the income above the cap to the top-row amount: 8.1 percent for one child, rising by steps to 20.4 percent for eight. Below $100 a week the schedules provide no amount at all; support is case by case, no minimum obligation exists, and a $0 order can be proper, because the court may not take a parent below a minimum subsistence level.
The 2024 amendments changed real numbers. Effective January 1, 2024, the schedule was re-based on newer economic data, ordinary health care costs came OUT of the schedule, and the old 6 percent rule for uninsured medical expenses was abolished. Uninsured health costs are now ordered separately, shared in proportion to income. Work-related child care and the children’s weekly health insurance premium still join the basic obligation on the worksheet, with a credit to the parent who pays the bill directly.
Parenting time earns a calculated credit, not a discount picked from the air. From 52 overnights a year, the Guideline 6 table assigns each 5-overnight band two factors, a total expense factor and a duplicated expense factor. The credit is the basic obligation times the total factor, minus the basic obligation times the duplicated factor times the noncustodial parent’s income share. The credit grows band by band to 183 overnights, and when near-equal time meets a higher-earning custodial parent, the arithmetic can flip the order so the custodial parent pays. Below 52 overnights there is no automatic credit, though courts keep discretion for infants, toddlers, and long-distance parenting.
Indiana also publishes a real official calculator at public.courts.in.gov/csc, which generates the court-ready worksheet and parenting time credit worksheet. Use this page to see every step of the math; use the state tool to file.
Worked example: the parenting time credit, band by band
- Take one child. The receiving parent earns $600 a week in adjusted income; the paying parent earns $800 a week and has the child 98 overnights a year, roughly what the Parenting Time Guidelines produce without extended weeknight stays.
- Combined weekly adjusted income is $1,400. The schedule row for $1,400 and one child is $233 a week. The paying parent earns $800 of the $1,400, a 57.1 percent share, so that parent’s slice of the basic obligation is $133.14 before any credit.
- Now the credit. 98 overnights falls in the 96 to 100 band of the parenting time table, which carries a total expense factor of 0.253 and a duplicated expense factor of 0.158.
- The formula runs: $233 times 0.253 is $58.95 of recognized parenting time expense. From that, subtract the duplicated share: $233 times 0.158 is $36.81, and 57.1 percent of it is $21.04. The credit is $58.95 minus $21.04, which is $37.91 a week.
- The order is $133.14 minus $37.91: $95.23 a week. That weekly figure is what an Indiana court orders. For comparison with other states, $95.23 times 52 weeks divided by 12 months is $412.66 a month.
The steps above follow the calculation method described on our methodology page.

- Guideline amendments on the four-year review cycle; most guidelines in the compiled official PDF still carry this effective-date stamp.source
- The Supreme Court order of October 17, 2023 took effect: the weekly schedule was re-based on 2013 to 2019 economic data, ordinary health care costs were removed from the schedule, the 6 percent uninsured-expense rule was abolished, and the parenting time credit table was recalibrated to start at 52 overnights.source
- The compiled official rules PDF was updated; the substantive provisions remain the January 1, 2024 amendments.source
Indiana child support FAQs
How is child support calculated in Indiana?
On a weekly income shares worksheet. Both parents’ weekly adjusted incomes are combined and looked up on the Guideline Schedules for Weekly Support Payments for the number of children. Work-related child care and the children’s health insurance premium join that basic obligation, each parent owes a share in proportion to income, and the noncustodial parent’s share, minus any parenting time credit and direct-payment credits, becomes the weekly order.
Why is Indiana child support weekly instead of monthly?
Because the Guidelines are built that way. The schedules are titled "Guideline Schedules for Weekly Support Payments," the worksheet lines are weekly, and orders issue in dollars per week. Websites that quote Indiana support as a monthly number are converting, and some convert badly by multiplying by four. The honest conversion is weekly times 52 divided by 12, and this tool shows both figures.
How many overnights change Indiana child support?
The credit table starts at 52 overnights a year and moves in 5-overnight bands to 183. Each band carries two factors, and the credit equals the basic obligation times the total factor minus the duplicated portion weighted by the paying parent’s income share. One overnight can matter: 95 overnights sits in one band and 96 in the next, and the weekly order steps at that line. Below 52 overnights there is no automatic credit, though courts may grant one for infants, toddlers, or long-distance parenting.
Can the custodial parent end up paying in Indiana?
Yes. When parenting time is near equal and the custodial parent earns more, the parenting time credit can exceed the noncustodial parent’s share. The Guidelines say the result should be an order running from the custodial parent to the noncustodial parent. This calculator computes that flip instead of stopping at zero, and labels the direction plainly.
What happened to the 6 percent rule for medical expenses?
It was abolished effective January 1, 2024. Before then, the custodial parent covered uninsured health costs up to 6 percent of the basic obligation. Now ordinary health care costs are out of the schedule entirely, and uninsured expenses are ordered separately, shared in proportion to income. If a guide still tells you to budget the 6 percent, it is describing the old law.
What if combined income is above $9,200 or below $100 a week?
Above $9,200, the schedule adds a percentage of the excess to the top-row amount: 8.1 percent for one child up to 20.4 percent for eight. Below $100, the schedules provide no amount at all. Support there is case by case, no minimum obligation exists, and a court may not deprive the paying parent of the means of self-support at a minimum subsistence level, so this tool declines to print a number in that zone.
Is there an official Indiana child support calculator?
Yes, and it is good. The Indiana Supreme Court runs a calculator at public.courts.in.gov/csc that produces the Child Support Obligation Worksheet and the Parenting Time Credit Worksheet in court-ready form, and you can save calculations with a free account. Use this page to understand each step and check the bands; use the court tool for filing.
Do prior children lower Indiana child support?
Through the income side. Court-ordered support actually paid for prior-born children comes off weekly gross, and prior-born children living in the parent’s home with no order earn a deduction computed from the schedules at that parent’s own income. The official commentary works the example: a parent grossing $400 a week with one prior-born child at home deducts $68, the one-child schedule amount at $400. This calculator runs the same lookup.
Good to know in Indiana
- The Guidelines are court rules, so changes come by Supreme Court order rather than legislation; the amendments in force took effect January 1, 2024, and the four-year federal review cycle points at 2028 for the next set.
- Support Rule 3 requires written findings for any deviation, and Guideline 2 caps child support plus temporary maintenance together at 50 percent of the paying parent’s weekly adjusted income.
- Children with different overnight counts get the credit computed at each count and averaged, a method the Court of Appeals blessed in Blanford v. Blanford (2010); this tool asks for one overnight figure, so use the average or run the official calculator for the exact split.
- A handful of the 911 official schedule rows are transcribed here. When your combined income snaps to a row we have not transcribed, the tool interpolates between the neighbors, marks the result an estimate, and points you to the official calculator for the exact cell.
How to use this estimate
Enter WEEKLY figures. Every money field on this form is dollars per week, because that is the unit the Indiana worksheet runs on. If you know a monthly amount, multiply it by 12 and divide by 52 first; the form hints repeat that shortcut.
Start from weekly gross income from any source, before taxes. If the paying parent already pays support for prior-born children under another order, has prior-born children at home with no order, or pays court-ordered spousal maintenance, use the dedicated fields; the Guidelines subtract each of those before the schedule lookup, and the in-home deduction is computed from the schedules themselves at that parent’s own income.
Count overnights honestly. The credit starts at 52 overnights and moves in 5-overnight bands, so a single overnight near a band edge changes the number, and the step is visible in the result lines. Above 183 overnights the roles are reversed: the parent with more than half the year is the custodial parent on this worksheet.
Read the result as the guideline figure a court starts from. The weekly line is the order; the monthly line is arithmetic for comparison. For filings, the Indiana Supreme Court calculator produces the worksheet the court wants, and a judge can deviate from the guideline amount with written findings.
What this estimate includes
- The Guideline Schedules at the rows our fixtures verify, in weekly dollars, with the nearest-row rule between rows
- The above-$9,200 marginal percentage extension, 8.1 to 20.4 percent by child count
- The full Guideline 6 parenting time table, 52 to 183 overnights, with the credit formula the official worksheet uses
- Prior-order support, in-home prior-born children, and court-ordered maintenance deductions from weekly gross
- Weekly child care and health insurance add-ons with direct-payment credits
- The flip to a custodial-parent-pays order when the credit exceeds the obligation
What it leaves out
- The income-finding itself: potential income for unemployed or underemployed parents and in-kind benefit values are court determinations
- Uninsured health care costs, which since 2024 are ordered separately in income proportion rather than added to the worksheet
- Combined weekly incomes below $100, where the schedules provide no amount and support is case by case
- Split custody, which Indiana handles through paired worksheets, and credit averaging for children with different overnight counts
- The exact values of untranscribed schedule rows; when the nearest row is not transcribed the tool interpolates and says so
