Post-Judgment Interest Calculator.
Apply dated rates, partial payments, costs, and per diem calculations in a transparent attorney-review worksheet.
This calculator prepares an attorney-review worksheet based on the selected assumptions and available rate data. Post-judgment interest rules, rate changes, compounding, day-count conventions, taxable costs, and payment application can vary by jurisdiction and judgment. Confirm the governing law and court requirements before relying on or filing the calculation.
See the math behind every payoff dollar.
Changing statutory rates, partial payments, interest-first allocation, costs, leap years, and per diem can make a payoff difficult to reconstruct. TORO separates the assumptions from the arithmetic and preserves each interval in a reviewable ledger.
Judgment.
Enter the judgment dates, matter references, and opening amounts.
Principal is interest-bearing. Classify each other opening component independently from the judgment and governing rule.
TORO does not assume that costs, fees, or prejudgment interest earn post-judgment interest.Interest rate.
Use the applicable state statutory rate or enter a simple annual rate.
Attorney-entered assumption. Confirm before use.
Costs and Additions.
Add dated amounts and choose whether each amount bears post-judgment interest.
No dated additions. Opening costs and fees are recorded above.
Payments.
Only Cleared payments reduce the estimate; excluded transactions remain in the ledger.
No payments entered. Add cleared, pending, returned, or voided payments to keep a complete audit ledger.
Assumptions.
Make the legal and mathematical choices visible before relying on or exporting the worksheet.
Under this selection, a cleared payment applies first to accrued unpaid interest, then interest-bearing principal, then non-interest-bearing costs. The attorney must confirm the controlling rule for the judgment.
Save this calculation with a free Lawyer account.
Recalculate through a later date, preserve rate snapshots and payment history, duplicate versions, add attorney notes, and explicitly attach a saved worksheet to an authorized Engagement.
Understand the worksheet before relying on it.
How is post-judgment interest calculated?
The worksheet divides the timeline at each rate change, payment, addition, and payoff date, then calculates interest for every interval using the selected rate and day-count assumption.
What is the United States Rule?
In this calculator it is an allocation option that applies a cleared payment first to accrued unpaid interest, then principal, then costs. It is not presented as the controlling rule for every judgment.
Are payments always applied to interest first?
No. The controlling judgment and jurisdiction may require a different rule. The worksheet also supports principal-first, pro-rata, jurisdiction-defined, and manual assumptions.
Does every state use the same rate?
No. Rates, categories, reset rules, compounding, costs, and date treatment vary. Unsupported or unreviewed jurisdictions require an attorney-entered rate assumption.
What happens when the statutory rate changes?
A changing-rate schedule is split into separate dated periods. A fixed judgment-date rate remains fixed when that is the reviewed rule.
Does interest accrue on court costs and attorney fees?
Not automatically. The user must classify additions as interest-bearing, non-interest-bearing, excluded, or a credit after reviewing the judgment and applicable rule.
How are leap years handled?
Actual/Actual uses the number of days in each calendar year. Actual/365 and Actual/366 use their stated fixed denominators, and 30/360 uses its selected convention.
Is the result guaranteed to be accepted by a court?
No. It is an attorney-review estimate. Confirm the judgment, governing law, court requirements, official rates, and calculation assumptions before relying on or filing it.
Can I use a custom rate?
Yes. You can enter a fixed rate or a dated rate schedule and preserve its citation or basis in the worksheet.
Can I export the calculation?
Yes. Public users can print or save a clean PDF worksheet after confirming the displayed assumptions.
Do I need a TORO account?
No. The public calculator works without an account. A free Lawyer account adds saved calculations, history, duplication, notes, versioning, and authorized Engagement attachment.
Is my public calculation stored?
No. Public inputs stay in the current browser tab and are not sent to TORO storage by the calculator.
Can I attach a calculation to an Engagement?
An authenticated Lawyer can explicitly attach a saved calculation to an authorized Engagement. Saving alone does not update balances, payments, milestones, or client-visible records.
