Before you can calculate child support payments in Indiana, gather these essential documents and information:
Income Documentation
- Your most recent paystubs (minimum 3 months, preferably 6-12 months)
- Tax returns for the past 2 years (including W-2s and 1099s)
- Year-to-date earning statement from your employer
- Documentation of bonuses or commissions received in the past year
- If self-employed: Profit & loss statements and business tax returns
Other Parent's Income Information
- Same documentation as above for the other parent
- If unavailable, you may need to file for discovery or use income imputation
Child-Related Expenses
- Health insurance premium statements showing child's portion
- Childcare invoices or contracts with costs
- Extraordinary medical expense records not covered by insurance
- Special education costs if applicable
Parenting Time Schedule
- Current or proposed parenting time schedule
- Calendar showing overnight count for past year (if modifying existing order)
Step-by-Step Calculation Process
1Calculate Each Parent's Weekly Gross Income
Start by determining the weekly gross income for both parents. This includes:
- Wages and salary (before taxes)
- Self-employment income (after ordinary business expenses only)
- Bonuses and commissions (averaged over the past year)
- Rental income, interest, dividends
- Social Security Disability (SSDI)
- Unemployment compensation
- Workers' compensation
Example:
- Parent 1: $52,000/year salary = $1,000/week
- Parent 2: $36,400/year salary = $700/week
2Apply Income Adjustments
Deduct qualifying obligations from each parent's gross income:
- Prior child support orders for other children
- Spousal maintenance (alimony) paid to another party
Example:
- Parent 1: $1,000 - $0 = $1,000/week adjusted
- Parent 2: $700 - $100 (prior support) = $600/week adjusted
3Calculate Combined Weekly Gross Income
Add both parents' adjusted weekly incomes together:
Example: $1,000 + $600 = $1,600/week combined
4Determine Basic Child Support Obligation
Use the Indiana Child Support Obligation Schedule found in the official guidelines to look up the basic weekly obligation based on combined income and number of children.
Approximate percentages:
- 1 child: ~14.5% of combined income
- 2 children: ~21.5%
- 3 children: ~27.5%
- 4 children: ~31.5%
- 5+ children: ~35.5%
Example (2 children): $1,600 × 21.5% = $344/week basic obligation
5Add Child-Related Expenses
Add these weekly costs to the basic obligation:
- Health insurance premiums (child's portion only)
- Work-related childcare costs
- Extraordinary medical expenses
- Special educational expenses (if court-approved)
Example:
- Basic obligation: $344/week
- + Health insurance: $50/week
- + Childcare: $150/week
- = Total obligation: $544/week
6Calculate Parenting Time Credit
If the non-custodial parent has 52+ overnights per year, apply the Parenting Time Credit per Guideline 6.
Credit formula (simplified):
- 52-127 overnights: 10-25% credit on basic obligation
- 128-182 overnights: 25-50% credit on basic obligation
Example (80 overnights):
- Credit ≈ 18% of $344 = $62/week credit
7Divide Obligation by Income Share
Determine each parent's proportionate share of the combined income:
Example:
- Parent 1: $1,000 ÷ $1,600 = 62.5%
- Parent 2: $600 ÷ $1,600 = 37.5%
8Calculate Final Payment Amount
Multiply the total obligation by the non-custodial parent's income share, then subtract their parenting time credit:
Example (Parent 1 is non-custodial):
- Total obligation: $544/week
- Parent 1's share: $544 × 62.5% = $340
- Less PTC: $340 - $62 = $278/week payment
Complete Calculation Example
Let's walk through a full calculation from start to finish:
Scenario:
- Parent 1: $900/week gross, no prior obligations, 65 overnights/year
- Parent 2: $600/week gross, no prior obligations
- 2 children
- Parent 2 pays $60/week health insurance for children
- Childcare costs $140/week
Step-by-Step:
- Combined income: $900 + $600 = $1,500/week
- Basic obligation (2 children, $1,500 combined): ~$323/week
- Add expenses: $323 + $60 + $140 = $523/week
- Parent 1's share: 60% ($900÷$1,500)
- Parent 1's portion: $523 × 60% = $314
- PTC for 65 overnights: ~$48 credit
- Final: Parent 1 pays $266/week

Calculate Now →Common Calculation Mistakes to Avoid
1. Using Net Income Instead of Gross
Always use gross income (before taxes and deductions). Using take-home pay will result in significantly incorrect calculations.
2. Forgetting to Convert to Weekly Amounts
Indiana calculations are done on a weekly basis. If you're paid monthly or bi-weekly, convert everything to weekly:
- Monthly salary: Multiply by 12, divide by 52
- Bi-weekly salary: Multiply by 26, divide by 52
3. Miscounting Overnight Visits
An overnight is only counted if the child sleeps at that parent's home. Daytime visits don't count. Be precise—even 10 nights can change your payment by $50+/month.
4. Including Non-Qualifying Income
Don't include means-tested benefits (TANF, SNAP), SSI, or child support received for other children.
5. Using Outdated Guidelines
Always use the most current year's guidelines. Our Indiana child support calculator is always updated with the latest rules.

Frequently Asked Questions
Do I need a lawyer to calculate child support?
No. You can calculate support yourself using the Indiana child support calculator for estimates, or the official state calculator for court filings. However, complex cases benefit from attorney review.
What if I don't know the other parent's income?
You can file a discovery request to obtain their financial information. If they don't respond, the court may impute income based on earning capacity or use other evidence.
How often should I recalculate?
Recalculate when:
- Either parent's income changes significantly
- Parenting time schedule changes
- Childcare or insurance costs change substantially
- It's been 12+ months since your last review
Can we agree to an amount different from the calculation?
Yes, but the court must approve it. Judges will only approve deviations if they're convinced the children's needs are met and it's in the child's best interest.
