What is Yield Maintenance in Commercial Real Estate?

You want to sell your property or refinance into a better rate. The timing feels perfect.

But when you request a payoff quote, the lender slaps you with a massive penalty fee. Selling early might suddenly wipe out all your equity just to satisfy the loan terms.

Here is exactly what is yield maintenance, how it protects the lender, and how to do the math before you decide to sell.

Why Yield Maintenance Exists

When a lender gives you a fixed-rate commercial loan, they expect a guaranteed stream of income for the life of that loan.

If interest rates drop, you might want to refinance. If you pay off the lender early, they now have a pile of cash but can only lend it out at the new, lower market rates. They lose money.

Yield maintenance prevents this. It forces you to pay the difference so the lender maintains their original expected yield. It is standard on most CMBS and Agency loans. If you want more flexibility, check our guide to commercial real estate loans for alternatives like bank loans.

The Math Behind It

The yield maintenance formula is complex, but the concept is straightforward.

Yield Maintenance = Present Value of Remaining Loan Payments − Present Value of Reinvesting the Payoff in Treasury Bonds

To figure out how to calculate yield maintenance, you compare two things. First, how much interest would you have paid if you kept the loan? Second, how much interest will the lender earn if they take your payoff money today and buy safe U.S. Treasury bonds?

You write a check for the difference.

A Calculation Example

Here is a simplified yield maintenance calculation example.

Assume you have a $10,000,000 loan at a 6% interest rate. You want to pay it off three years early. If you kept the loan, you would pay roughly $600,000 in interest per year, totaling $1,800,000 over those final three years.

If you pay the lender $10,000,000 today, they will invest it in 3-year Treasury bonds. If the current Treasury rate is 4%, they will only earn $400,000 a year, or $1,200,000 over three years.

They expected $1,800,000. They will only get $1,200,000. Your yield maintenance calculation dictates that you owe them the $600,000 difference (discounted to present value).

When Rates Go Up

Yield maintenance is terrifying when market rates fall. But what happens when rates rise?

If the current Treasury rate climbs to 7%, the lender can take your payoff money and earn more than the 6% you were paying them. In this scenario, the penalty drops to zero.

However, almost all loan agreements include a minimum penalty floor. Typically, this is 1% of the outstanding loan balance. So even if rates skyrocket, you still pay a 1% exit fee.

If you are evaluating whether to buy a property with an existing loan, always factor in the exit penalty. While evaluating debt yield helps you get the loan, understanding prepayment penalties is what allows you to exit it cleanly.
