⚠️ Important: This is an estimate. Actual yield maintenance calculations vary by lender and loan document. Some use the greater of the YM formula or 1% of the balance. Defeasance (CMBS) is calculated differently. Always review your loan documents or consult your advisor for exact figures.

Understanding Prepayment Penalties

Know what you owe before you refinance, sell, or pay off your CRE loan early.

What Is Yield Maintenance?

Yield maintenance compensates the lender for lost interest when you prepay. It calculates the present value of the difference between your note rate and the current Treasury rate for the remaining term. When rates drop, yield maintenance gets expensive because the rate gap widens.

When Is YM Cheapest?

Yield maintenance is cheapest when current Treasury rates are close to or above your note rate (the rate differential shrinks or disappears), or when you are very close to loan maturity (fewer months of lost interest). In a rising rate environment, YM penalties can be near zero.

YM vs Defeasance

Defeasance replaces your loan collateral with Treasury bonds instead of paying a penalty. Common in CMBS loans. It is often more expensive than yield maintenance because of transaction costs (legal, accountant, securities dealer fees). Defeasance can cost $50K–$150K+ in fees alone.

Step-Down vs Flat Penalties

Step-down penalties (e.g., 5-4-3-2-1%) decrease each year and are simpler to calculate. Flat penalties (1–3% of balance) are the most borrower-friendly. When negotiating new loans, the prepayment structure should be a key consideration — our advisors help you get the best terms.

Frequently Asked Questions

Common questions about yield maintenance and prepayment penalties.

How is yield maintenance calculated?

Yield maintenance = Present Value of (Note Rate − Treasury Rate) × Remaining Balance for each month remaining. In simplified terms, it's the present value of the interest differential the lender would lose. When rates are much lower than your note rate, YM is expensive because the lender loses more income.

What Treasury rate should I use?

Use the Treasury rate matching your remaining loan term. If you have 5 years left, use the 5-year Treasury yield. If 3 years, use the 3-year Treasury. Some loan docs specify which Treasury to use — always check your specific loan agreement for the defined replacement rate.

When does yield maintenance cost the most?

YM is most expensive when: (1) your note rate is much higher than current Treasury rates (large rate differential), (2) you have many years remaining on the loan (more months of lost interest), and (3) Treasury rates are low (deeper discount widens the gap). In a rising rate environment, YM can approach zero.

Can I negotiate to avoid yield maintenance?

On new loans, yes. You can negotiate step-down penalties instead of YM, open prepayment periods after a certain date, or a flat penalty structure. Bridge loans and some portfolio lenders offer open prepay. The prepayment structure should be negotiated before closing — our advisors ensure favorable terms.

What is the difference between yield maintenance and defeasance?

Yield maintenance is a cash penalty paid to the lender. Defeasance replaces your loan collateral with Treasury bonds that replicate the remaining payment stream, then releases the property. Defeasance is common in CMBS loans and typically costs more due to legal and transaction fees ($50K–$150K+).

How does BestLoanUSA help with prepayment penalties?

We review your current loan documents to calculate the exact penalty, determine if refinancing still makes sense after accounting for the penalty cost, and negotiate better prepayment terms on your next loan. Many borrowers overpay on penalties simply because they don't calculate them before committing.
