What Is Yield Maintenance?

Yield maintenance is a prepayment penalty clause often found in commercial loans or mortgages. It ensures lenders don’t lose interest income if a borrower pays off a loan early. The calculation compensates the lender for the “lost interest” they would have earned if the loan had continued to maturity.

Key terms to know:

Loan Original Balance: The initial amount borrowed
Remaining Balance: What you still owe on the loan
Treasury Rate: The benchmark interest rate (e.g., U.S. Treasury yield)
Time to Maturity: Years left until the loan’s end date

Without the right tools, calculating this penalty manually can lead to errors. That’s where our Chatham Yield Maintenance Calculator comes in.

Why Yield Maintenance Calculations Matter

Understanding your prepayment penalty helps you:

Avoid surprises: Know precisely what you’ll owe before making early payments.
Plan finances: Decide whether refinancing or prepaying is cost-effective.
Negotiate better terms: Use the data to discuss options with your lender.

For example, knowing your yield maintenance fee upfront can save thousands of dollars if you sell a property or refinance a mortgage.

Common Questions About Yield Maintenance

How Do You Calculate Yield Maintenance?

Yield maintenance is calculated to compensate lenders when borrowers pay off loans early. Here’s the simple formula:

Yield Maintenance = Remaining Loan Balance × (Loan Interest Rate − Treasury Rate) × Time to Maturity

Example:

Remaining Balance: $500,000
Rate Difference: 5% (Loan Rate) − 3% (Treasury) = 2%
Time Left: 5 years
YM =
500,000×0.02×5=
500,000×0.02×5=50,000

What Is the Minimum Yield Maintenance?

The “minimum yield maintenance” is the lowest prepayment penalty you’ll pay, even if market rates rise. This floor is usually:

Defined in your loan agreement (often 1-3% of the remaining balance)
Protects lenders if Treasury rates exceed your loan rate

Why it matters: You’ll never pay less than this minimum, even if the formula suggests a lower amount.

What is the difference between defeasance and yield maintenance?

3. Defeasance vs Yield Maintenance: Key Differences

Factor	Yield Maintenance	Defeasance
Cost	Cash payment	Purchase Treasury securities
Speed	Instant payoff	Takes 30-90 days
Flexibility	Simpler process	Complex legal/financial setup
Best For	Short-term loans	Long-term commercial mortgages

Simple analogy:

Yield maintenance = Paying a fee to exit a gym membership early
Defeasance = Finding a replacement member to take over your contract

**difference between defeasance and yield maintenance**

Can Yield Maintenance Be Negative?

No, yield maintenance cannot be negative. Here’s why:

If Treasury rates > Loan rates, the penalty defaults to the minimum yield maintenance (see #2 above)
Lenders never pay you for prepaying – they only recover lost profits

Exception: Some rare loans allow “negative prepayment,” which is uncommon in commercial real estate.

Tips for Accurate Calculations

Double-check Treasury rates from reliable sources like the U.S. Treasury website.
Use the exact remaining balance numbers from your latest loan statement.
If unsure about the time to maturity, contact your lender for clarity.
