Indiana Child Support Calculator

Indiana Rules of Court Child Support Guidelines & Parenting Time Credit Tables
In the State of Indiana, child support is governed by the comprehensive Indiana Child Support Rules and Guidelines promulgated by the Indiana Supreme Court. Grounded in the Income Shares framework, the Indiana guidelines operate on a unique weekly accounting methodology: all parental earnings, work-related childcare expenses, health insurance premiums, and final support obligations are calculated and expressed on a weekly dollar basis.
A distinctive feature of Indiana family law is the Parenting Time Credit Table. Rather than using an abrupt mathematical threshold, the Indiana Supreme Court establishes an extensive tiered lookup table spanning 52 to 183 overnights. The guidelines recognize that as a non-custodial parent exercises more overnight parenting time, they directly absorb duplicate variable child expenses (such as food, entertainment, and utilities), justifying a graduated percentage discount against their weekly basic support obligation.
ToolQix's Indiana Child Support Calculator accurately models the weekly gross income shares algorithm, incorporates allowable prior-born child deductions, applies the official Indiana Parenting Time Credit table, and provides instantaneous conversion to monthly budget figures.
Weekly Gross Income Shares, Prior Child Deductions & Credit Interpolation
Indiana guidelines calculate Weekly Gross Income ($W_1, W_2$) by summing wages, self-employment, and irregular income, then subtracting legal credits for prior-born children or court-ordered spousal maintenance. The Combined Weekly Gross Income is $W_c = W_1 + W_2$, with percentage shares $S_1 = W_1 / W_c$ and $S_2 = W_2 / W_c$. The Basic Child Support Obligation is derived from the Indiana Child Support Guideline Schedule. Work-related childcare and weekly child health insurance premiums are added to establish the Total Weekly Obligation. The paying parent's preliminary weekly obligation is discounted using the official Indiana Parenting Time Credit Table percentage based on annual overnights.

Best Practices & Operational Tips
- Always use weekly figures: convert bi-weekly pay by multiplying by 26 and dividing by 52; convert monthly pay by multiplying by 12 and dividing by 52.
- The Indiana Parenting Time Guidelines establish a standard minimum schedule (alternating weekends, one weekday evening, half of all holidays, and 4 weeks in summer = roughly 96 to 100 overnights).
- Do not omit the 6% rule for uninsured health care expenses: the custodial parent is legally expected to absorb uninsured medical costs up to 6% of the annual basic support obligation before the non-custodial parent must contribute.
- Remember that Indiana terminates child support at age 19 (emancipation), not age 18, unless an earlier legal emancipation occurs.

Frequently Asked Questions about Indiana Child Support Calculator
When does child support end in Indiana?
Under Indiana Code § 31-16-6-6, the legal duty to support a child ceases when the child turns 19 years old, unless the child is legally emancipated earlier (e.g., marries, enters active military service) or is incapacitated.
What is the 6% rule for medical expenses in Indiana?
In Indiana, the basic child support schedule assumes that 6% of the annual basic support obligation is spent on ordinary medical expenses (band-aids, over-the-counter medicine, routine co-pays). The custodial parent must pay this initial 6% threshold out-of-pocket each calendar year before requesting proportional contribution from the other parent for uninsured extraordinary medical expenses.
Does Indiana consider overtime pay when calculating gross income?
Yes. Indiana includes overtime and second job earnings in gross income. However, judges have the discretion to exclude or discount irregular or non-mandatory overtime if the parent demonstrates that working extra hours is not sustainable or was undertaken solely to pay down marital debt.
