How to calculate interest in Indiana

Quick takeaways

• Indiana generally awards post-judgment interest on money judgments from the date of verdict/findings until satisfaction under Ind. Code §§ 24-4.6-1-101 through 24-4.6-1-103.
• If your contract specifies an agreed interest rate, Indiana’s judgment interest framework typically uses “the rate agreed upon”—but Indiana caps that contract rate at the statutory maximum in Ind. Code § 24-4.6-1-101.
• DocketMath’s interest calculator is designed for a jurisdiction-aware workflow: enter your start date (verdict/findings return), choose the appropriate rate logic, and compute interest through the satisfaction date.
• No special “claim-type” sub-rule was identified in the provided Indiana default framework—so this guide treats Indiana’s general/default post-judgment interest period as the governing approach.

Inputs you need

To calculate Indiana interest in DocketMath, gather the following items before you open the calculator:

• Judgment interest start date

  • Indiana ties accrual to “the date of the return of the verdict or finding of the court.” (Ind. Code § 24-4.6-1-101)
• Satisfaction date

  • Interest ends “until the satisfaction thereof.” (Ind. Code § 24-4.6-1-101)
• Interest rate basis

  • Contract rate (if applicable): the statute uses “the rate agreed upon in the original contract sued upon,” but Indiana limits it with a statutory maximum. (Ind. Code § 24-4.6-1-101)
  • Otherwise statutory rate: if no contract rate applies under your facts, DocketMath can apply the default Indiana approach using the statutory framework referenced in Ind. Code §§ 24-4.6-1-101 through 24-4.6-1-103.
• Cap/limit confirmation

  • The contract rate is subject to a cap: “shall not exceed an annual rate …” as stated in Ind. Code § 24-4.6-1-101.
• Compounding vs. simple interest setting

  • DocketMath’s UI may include options (depending on the calculator design). Use the option that aligns with the rate/accrual structure you intend to model for the Indiana judgment interest framework.

Checklist for a clean run in DocketMath:

• I have the verdict/findings return date (not just a later judgment entry date)
• I have the satisfaction/payment date (or an estimate, if you need a projection)
• I know whether there is an original contract sued upon that includes an agreed interest rate
• I can confirm whether the statutory maximum cap limits the contract rate

How the calculation works

1) Choose the accrual period (Indiana default rule)

Indiana’s default framework for post-judgment interest on money judgments is:

• Interest accrues from: the date of return of the verdict or finding of the court
• Interest accrues until: satisfaction of the judgment

This wording is in Ind. Code § 24-4.6-1-101:

“Except as otherwise provided by statute, interest on judgments for money whenever rendered shall be from the date of the return of the verdict or finding of the court until the satisfaction thereof…”

Important clarification (based on the provided note): no claim-type-specific sub-rule was found in the Indiana default rule set you provided. So this walkthrough applies the general/default period above.

Practical impact on your numbers

• Changing the start date earlier (even by a few days) increases total interest because more days accrue.
• Changing the satisfaction date later increases total interest because the accrual continues.

2) Determine the interest rate to apply

Indiana’s statute links the rate to what is agreed upon in the underlying contract, subject to a statutory cap.

In Ind. Code § 24-4.6-1-101, the statute includes:

• “the rate agreed upon in the original contract sued upon”, and
• a cap: “which shall not exceed an annual rate …”

So in DocketMath, mirror that logic:

• If a contract rate applies:

  • Use the contract’s agreed rate, but ensure it does not exceed the Indiana cap in Ind. Code § 24-4.6-1-101.
• If a contract rate does not apply:

  • Use the Indiana statutory rate framework described in Ind. Code §§ 24-4.6-1-101 through 24-4.6-1-103.

If you’re unsure whether a contract rate “applies” to your judgment under Indiana law, treat the rate-selection step as a facts-validation step before you finalize the output.

3) Convert the annual rate to daily accrual (calculator mechanics)

Indiana’s statute is written in annual-rate terms, but interest is typically calculated over elapsed time. In practice, calculators (including DocketMath) commonly:

• compute a daily rate derived from the selected annual rate (often annual/365 unless the tool uses a different basis), and
• multiply the judgment principal by the daily rate and the number of days between the start and end dates.

What changes as you update inputs?

Typical DocketMath sensitivity looks like this:

• Earlier verdict/findings return date → more days → higher interest
• Later satisfaction date → more days → higher interest
• Higher rate (within the cap) → higher daily accrual → higher interest
• Switching from contract rate to statutory rate → could significantly change total interest

4) Set up the DocketMath calculation

Use the interest calculator:

1. Open DocketMath interest: /tools/interest
2. Enter:

   • Start date = verdict/findings return date (Ind. Code § 24-4.6-1-101)
   • End date = satisfaction date
   • Principal = judgment amount subject to interest
3. Select the rate method that matches Indiana’s framework:

   • Contract rate (capped) if there is an agreed contract rate that applies, and enforce the cap from Ind. Code § 24-4.6-1-101
   • Otherwise Indiana statutory rate using Ind. Code §§ 24-4.6-1-101 through 24-4.6-1-103
4. Confirm any day-count and compounding/simple settings shown by DocketMath.
5. Review the results (total interest and any breakdown provided by the tool).

Common pitfalls

1) Using the wrong start date

Indiana uses “the date of the return of the verdict or finding of the court” (Ind. Code § 24-4.6-1-101), not the date the court later “enters judgment.”

Common mistakes:

• using the judgment entry date instead of verdict/findings return date
• using the date you filed a motion rather than the verdict/findings return date

2) Ignoring the “until satisfaction” end point

The statute runs “until the satisfaction thereof” (Ind. Code § 24-4.6-1-101).

Pitfalls:

• stopping at the date a judgment is entered (rather than the date money was actually satisfied)
• using an estimate end date and forgetting to update it when satisfaction occurs

3) Forgetting the statutory cap on contract rates

Indiana requires that the contract rate “shall not exceed an annual rate …” (Ind. Code § 24-4.6-1-101).

Pitfall:

• entering a contract rate that is above the cap without limiting it

4) Mixing pre-judgment and post-judgment frameworks

This statute section is about interest on judgments for money whenever rendered (Ind. Code § 24-4.6-1-101). Pre-judgment interest rules (if relevant) may come from different doctrines/statutes.

Pitfall:

• applying the post-judgment statute to a pre-judgment damages period

5) Assuming a claim-type-specific Indiana branch exists

Based on your note, no claim-type-specific sub-rule was found in the Indiana default framework you provided. This guide therefore applies the general/default accrual rule.

Pitfall:

• creating special branching logic without a cited Indiana basis
