Post-judgment interest in Colorado
An unpaid Colorado money judgment earns 8% a year unless the judgment or a contract says otherwise. On a $5,000.00 judgment that is $400.00 in the first year, about $1.10 a day.
How the rate is set
Fixed in the statute at 8% a year, compounded annually, for a judgment with no contract rate that is not appealed. It changes only when the legislature acts.

When a different rate applies
- A contract's stated rate governs.
- A personal-injury tort judgment bears 9% compounded annually from the date the suit was filed.
- An appealed judgment uses a rate the Secretary of State certifies each January, never below 8%.
- Medical debt is capped at 3%.
Work out your own judgment
Colorado is prefilled at 8%. Enter the amount and the date the judgment was entered. The calculator uses simple interest; Colorado compounds annually, so a judgment older than a year has earned a little more than this shows.
How Colorado's rate is set, and where it comes from
Uses simple interest at the rate you enter — pre-filled with each state's standard statutory rate, editable since some states publish a new rate quarterly or annually. Some states apply a different rate to specific debt types (noted above where it applies) or when a contract specifies its own rate. Informational only, not legal advice; confirm the current rate and any exceptions with your court clerk before relying on this figure.
The formula, worked
Last reviewed: October 2026
Interest = principal × rate × days ÷ 365. For $5,000.00 at 8%: $5,000.00 × 0.08000 × 365 ÷ 365 = $400.00 after one year, and $1.10 for each further day. Because Colorado compounds annually, year two accrues on $5,400.00: $432.00.
What this page does not know
- The rate written on your judgment. If the court stated a rate, that one applies, whatever the default is today.
- Partial payments. Interest accrues only on what is still unpaid.
