§ 334.01 — Rate of Interest

Plain-Language Summary

The default interest rate in Minnesota is 6% per year. The maximum rate anyone can charge is 8% per year, unless a higher rate is agreed to in writing. Interest cannot be compounded. For loans of $100,000 or more, there are no limits on interest rates. Loans from retirement plans under ERISA are also exempt.

Practical Notes
This is the foundational usury law in Minnesota. For personal loans under $100,000, lenders generally cannot charge more than 8% interest. However, many types of lenders (banks, credit unions) are governed by other statutes that may allow higher rates. Contracts that raise the interest rate after the due date forfeit all interest.
