📌 Quick Answer: Yield maintenance = Loan Balance × (Loan Rate − Treasury Yield) × PV Factor. For a $5M loan at 5.5% with 4.0% Treasury and 48 months remaining, the calculated penalty is ~$262,500. A 1% minimum floor ($50,000) applies if the calculation falls below it .
📋 Key Takeaways — Yield Maintenance 2026
YM = Present Value of spread between loan rate and Treasury yield
Higher rate differential = higher penalty
If Treasury ≥ Loan Rate, calculated YM is zero
Most loans have a 1%–3% minimum floor
Common in CMBS, Fannie Mae, Freddie Mac, life company loans
Cheaper than defeasance for loans with under 3 years remaining
Final 3–6 months often have an open prepay window
ℹ️ This yield maintenance calculator uses the standard commercial real estate formula. It estimates the prepayment penalty for CMBS, agency, and life company loans .
💡 Important: In a rising-rate environment, Treasury yields may exceed your loan rate, making the calculated YM zero. But the minimum floor still applies .
This yield maintenance calculator 2026 estimates the prepayment penalty on commercial real estate loans using the standard industry formula. Yield maintenance protects lenders from losing interest income when a borrower pays off a loan early .
The formula has three components: the rate differential (loan rate minus Treasury yield), the present value factor (which discounts the remaining payment stream), and the loan balance. Multiply them together, then apply the minimum floor if the result falls below it .
For a $5M loan at 5.5% with 48 months remaining and a 4.0% Treasury yield, the rate differential is 1.5%, the PV factor is approximately 3.5, and the calculated penalty is about $262,500 — roughly 5.25% of the loan balance .
When Yield Maintenance Is Zero
If the current Treasury yield equals or exceeds your loan rate, the spread is zero or negative. The calculated yield maintenance is zero. This happens in rising-rate environments, where the lender can reinvest the prepaid principal at a higher rate and doesn't need compensation .
However, most loan documents include a minimum penalty floor of 1%–3% of the outstanding balance. So even when the formula produces zero, the borrower still pays the floor amount .
Yield Maintenance vs. Defeasance
Both are prepayment penalties, but they work differently :
Yield Maintenance: Borrower pays a cash penalty calculated from the rate differential. Simpler, faster, and often cheaper for loans with under 3 years remaining.
Defeasance: Borrower purchases Treasury securities to replace the loan's cash flow. More complex, with fixed costs of $60,000–$150,000+, but may be cheaper for longer remaining terms.
For a loan with 48 months remaining, yield maintenance is typically the more economical exit. For a loan with 8+ years remaining, defeasance may be cheaper depending on the rate environment .
Why the Rate Environment Drives Everything
The same loan, prepaid at the same time, can have wildly different penalties depending on Treasury yields. A loan originated in 2021 at 3.40% with a 5.01% Treasury yield in 2026 produces a negative spread and a zero calculated YM — floored at 1%. But if that same loan were prepaid in a low-rate environment (1% Treasury), the penalty could reach 12% of the balance or more .
This sensitivity is why commercial real estate borrowers model yield maintenance before making any prepayment decision. The difference between a $50,000 floor and a $2.7M penalty is entirely determined by where rates are when you exit .

❓ Frequently Asked Questions
What is yield maintenance in commercial real estate?
Yield maintenance is a prepayment penalty that compensates a lender for lost interest income when a borrower pays off a commercial loan early. It equals the present value of the spread between the loan's rate and a comparable Treasury yield over the remaining term .
How is yield maintenance calculated?
Formula: YM = Loan Balance × (Loan Rate − Treasury Yield) × Present Value Factor. The PV Factor = (1 − (1 + Treasury)^(-Months/12)) ÷ Treasury. A minimum penalty (typically 1%–3% of balance) often applies .
When is yield maintenance zero?
If the current Treasury yield is equal to or higher than the loan rate, the spread is zero or negative, and the calculated yield maintenance is zero. However, most loans still apply a minimum floor of 1%–3% of the outstanding balance .
What loans use yield maintenance?
Yield maintenance is common in CMBS loans, Fannie Mae DUS loans, Freddie Mac multifamily loans, and life company commercial mortgages. It is less common in bank portfolio loans, which may use step-down prepayment penalties instead .
Is yield maintenance cheaper than defeasance?
For shorter remaining terms (under 3 years), yield maintenance is often cheaper because the penalty declines as maturity approaches. Defeasance has higher fixed costs ($60,000–$150,000+) but may be more economical for longer remaining terms .
💡 Expert Tips for Yield Maintenance
Tip #1: Check your loan documents for the exact PV factor formula and floor percentage. The difference between 1% and 3% floors can be hundreds of thousands of dollars .
Tip #2: Time your prepayment. If Treasury yields are rising, waiting can reduce your penalty. If they're falling, prepaying sooner may be cheaper.
Tip #3: Model both yield maintenance and defeasance before choosing. The cheaper option depends on your remaining term and the rate environment .
Tip #4: The final 3–6 months often have an open prepay window. If you can wait, you may avoid the penalty entirely .
Tip #5: Ask your servicer for an official payoff quote before making any financial commitments. This calculator is an estimate, not a binding quote.
