Post-judgment interest in Oklahoma
An unpaid Oklahoma money judgment earns 8.75% a year unless the judgment or a contract says otherwise. On a $5,000.00 judgment that is $437.50 in the first year, about $1.20 a day.
How the rate is set
The prime rate listed in the first edition of the Wall Street Journal published each calendar year, plus 2%, as certified by the State Treasurer. An unpaid judgment rolls to each new year's rate on January 1, and that year's rate applies to the interest already accrued, so interest compounds annually in effect.

Work out your own judgment
Oklahoma is prefilled at 8.75%. Enter the amount and the date the judgment was entered. The calculator uses simple interest; Oklahoma compounds annually, so a judgment older than a year has earned a little more than this shows.
How Oklahoma'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 8.75%: $5,000.00 × 0.08750 × 365 ÷ 365 = $437.50 after one year, and $1.20 for each further day. Because Oklahoma compounds annually, year two accrues on $5,437.50: $475.78.
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.
- Whether a change has already applied to your judgment: Oklahoma re-rates existing judgments on its schedule, so an older judgment has carried more than one rate.
Informational only, not legal advice. Every figure is cited to the statute or the office that publishes it; confirm the current rate with the court clerk before relying on it.
Frequently asked questions
What is the post-judgment interest rate in Oklahoma right now?
8.75% a year for an ordinary money judgment, for calendar 2026, under 12 O.S. §727.1(I).
How is the Oklahoma rate set?
The prime rate listed in the first edition of the Wall Street Journal published each calendar year, plus 2%, as certified by the State Treasurer. An unpaid judgment rolls to each new year's rate on January 1, and that year's rate applies to the interest already accrued, so interest compounds annually in effect.
Is it simple or compound interest?
Compound, added to the balance once a year, so the second year's interest is calculated on principal plus the first year's interest.
Can my Oklahoma judgment carry a different rate?
Yes. Against a government defendant the total including interest is capped by the Governmental Tort Claims Act. The judgment itself may also state a rate, and that controls.
