If the contract is silent, no contractual interest accrues before suit; once a complaint is filed, the judgment-interest formula applies (5-yr Treasury auction average +1 pt, reset semi-annually, compounded annually).

Michigan's default (contract silent): no automatic rate. Published figure: 4.959% (Jul–Dec 2026) — see the note above for when it applies, confirm it on the official page, then enter the rate that applies (or your contract's rate).

The cited statute provides for annual compounding; this calculator shows simple interest, so multi-year totals under the statute will be slightly higher.

About this page

Michigan rent late fee law

Michigan's landlord and tenant statutes (the Truth in Renting Act and MCL chapter 554) contain no late fee provision, so they neither cap a late rent fee nor give a grace period.

Read in full for this check: Michigan Compiled Laws: Truth in Renting Act (1978 PA 454), 1972 PA 348 (landlord and tenant relationships) and the rest of MCL chapter 554, and Revised Judicature Act chapter 57 (summary proceedings to recover possession). Official source, read from the copy archived on 2026-01-06 · checked .

Before you send the late rent notice: it is a reminder letter about overdue rent and a late charge, not an eviction notice. A notice to pay rent or quit is a separate document, and Michigan has its own rules for it. Nothing on this page is legal advice.

What Michigan law says about invoice interest

The interest of money shall be at the rate of $5.00 upon $100.00 for a year, [...] except that in all cases it shall be lawful for the parties to stipulate in writing for the payment of any rate of interest, not exceeding 7% per annum.

Corporations/business entities may agree to any rate (civil usury defense barred), but the 25%/yr criminal-usury cap still binds them — that is the real B2B ceiling.
