Background
In my 15 years working with commercial borrowers, exit fees are one of the most common sources of unexpected closing costs when owners refinance, sell, or relocate. Lenders introduced these provisions decades ago to protect projected interest income on large, long‑term loans.
Common calculation methods
-
Flat fee: A fixed dollar amount specified in the loan agreement (for example, $15,000). Simple and predictable.
-
Percentage of remaining balance: A stated percent times the outstanding principal when you prepay (for example, 5% of the remaining balance).
-
Yield maintenance (prepayment premium based on present value): The lender calculates the present value of the remaining scheduled payments at the contract rate and subtracts the present value of what the lender can reinvest those funds to earn at current market rates (often using a comparable U.S. Treasury yield plus a spread). The shortfall becomes the exit fee. This method aims to compensate the lender for the economic loss caused by early repayment.
-
Defeasance (commercial mortgages/CMBS): Rather than paying a cash penalty, the borrower buys a portfolio of government or Treasury securities to replace the loan’s cash flows and transfer the collateral cash flows to the lender (common in securitized commercial mortgages).
How yield maintenance works (plain language)
- Lender totals the remaining scheduled principal and interest payments.
- Lender determines a replacement yield (often based on Treasuries of similar maturity plus a contract spread).
- The remaining payments are discounted to present value using that replacement yield. The difference between the original loan’s remaining cash flows and the discounted replacement value is the yield‑maintenance fee.
Small example
- Original loan: $1,000,000 at 5.00% fixed, 10‑year amortization.
- After 5 years the remaining principal is $500,000.
Possible exit fees:
- Flat fee: $15,000 (if specified).
- Percentage: 5% of remaining principal = $25,000.
- Yield maintenance: if current reinvestment yields are lower than 5%, the PV difference could be larger; if market yields are higher, the fee could be lower or zero (depending on the contract).
Who is affected
Small businesses, commercial real estate investors, and corporations with fixed‑rate or securitized loans are the most affected. Borrowers who plan to refinance, sell an asset, or pay down a loan early should check prepayment language before committing to property purchases or capital projects.
Negotiation and mitigation strategies
- Negotiate the clause at origination: ask for a capped fee, a step‑down schedule, or a short prepayment window without penalty.
- Request a short look‑back or breakpoints that reduce the fee over time.
- Ask for alternative remedies such as a flat fee option or ability to defease (if available).
- Time the payoff: some agreements waive penalties in a narrow early‑term window or after certain anniversary dates.
- Shop lenders: different lenders and loan products use different methods—compare the total cost of exit provisions along with interest and other fees.
Practical notes and red flags
- Always read the prepayment/prepayment‑premium clause in the loan agreement. Wording matters: “prepayment penalty,” “prepayment premium,” “yield maintenance,” and “defeasance” are different legal and economic outcomes.
- For CMBS or securitized loans, defeasance and prepayment premiums can be complex and costly—get counsel and a broker experienced in those markets.
- Confirm the replacement yield or Treasury curve the lender will use; some lenders use proprietary spreads or different Treasury maturities.
Tax and accounting considerations
Treatment of an exit fee for tax purposes can vary by business type and how the fee is characterized (e.g., interest expense vs. capital expense). Consult your CPA or tax advisor before assuming deductibility. (See IRS guidance or speak to a tax professional.)

Professional tips (from practice)
- Ask the lender for a written payoff quote showing the method used and the inputs (Treasury curve or spread). If the lender cannot provide a transparent calculation, negotiate for clearer terms.
- Run a worst‑case scenario: compare highest reasonable exit fee to the cost of staying in the loan.
- If refinancing is likely, build an exit fee contingency into your pro forma and cash reserves.
