Post-judgment interest
Oklahoma's post-judgment interest rate is 8.75% per year. Oklahoma’s 2026 general post-judgment rate is 8.75%. Under 12 O.S. §727.1, a covered judgment begins at the certified rate for the calendar year in which it is rendered and reprices each January 1 while unpaid. Previously accrued post-judgment interest joins the interest-bearing balance, so the statutory path compounds annually rather than using simple interest.

Section 727.1(C) expressly applies each new year’s rate to the judgment together with post-judgment interest previously accrued. That is annual compounding. StatuteRates keeps the calculator disabled because day count, partial-payment allocation, every special-law judgment, government-cap application, contract terms, and older statutory regimes are not calculator-complete. General post-judgment interest begins on the earlier of the expressly stated rendition date or filing with the court clerk. Allowed costs and attorney fees use their own earlier-of-pronouncement-or-filing trigger. The balance then reprices each January 1 at the certified rate for the new calendar year.
