What Is a Yield Maintenance Penalty?
Yield maintenance is one of the most punishing prepayment penalty structures in commercial lending. Borrowers who do not understand it before signing can find that prepaying or refinancing early costs hundreds of thousands of dollars more than they expected.
What It Does
Yield maintenance is designed to keep the lender economically whole if the borrower prepays. The penalty is calculated as the present value of the difference between the remaining contract interest payments and what the lender could earn by reinvesting the prepaid principal at current Treasury rates.
Why It Can Be Huge
When rates have dropped since origination, yield maintenance can be substantial — easily 5–10% of the loan balance, sometimes more. When rates have risen, the penalty may be zero. The math is rate-environment dependent.
Common in Agency and Long-Term Bank
Yield maintenance is standard on Fannie Mae and Freddie Mac multifamily loans, life company loans, and many longer-term bank commercial loans. It is less common on short-term debt and SBA loans.
Step-Down and Open Periods
Alternative prepayment structures include step-down penalties (e.g., 5% in year 1, 4% year 2, declining annually) and open periods near maturity (typically the last 3–6 months) when prepayment is free. Negotiate these provisions where possible.
