⚠️ 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.
