For the general MCL 600.6013(8) branch, Michigan’s current rate is 4.959%: the State Treasurer’s five-year Treasury benchmark for the period beginning July 1, 2026, plus one percentage point. General interest usually runs from complaint filing through satisfaction and compounds annually. Written instruments, future damages, tort settlement offers, medical-malpractice cases, and older complaint dates can follow different rules, so this page is a verified reference rather than a payoff calculator.
How Michigan post-judgment interest works
Which rate applies
The headline is Michigan’s general MCL 600.6013(8) branch. Complaint-date rules, written instruments, tort settlement offers, medical-malpractice provisions, and future damages can change the applicable treatment. For current written-instrument complaints, a specified lawful rate can govern, subject to the statutory 13% ceiling and other conditions.
When interest accrues
The general statute runs interest from complaint filing through satisfaction. For covered complaints, subsection (1) excludes the future-damages component between complaint filing and judgment entry; that component begins accruing at judgment.
Compounding and rate lock
Interest under the general and current written-instrument branches compounds annually. The statute calculates the general path in six-month intervals from complaint filing using benchmark rates certified for January 1 and July 1. Exact interval, anniversary, day-count, partial-payment, and branch mechanics remain withheld from calculation.
Official history coverage
Michigan Treasury publishes 80 semiannual five-year Treasury benchmark observations from January 1, 1987 through July 1, 2026. The general statutory rate is each benchmark plus one percentage point. Older complaint-date branches are documented separately rather than being flattened into this series.
