On a residential mortgage you can usually pay the loan off early without a penalty. Commercial loans are different. Most commercial loan agreements include a prepayment penalty, and it can be large enough to change the math on a sale or a refinance. If you do not understand which penalty structure your loan carries, an early payoff can cost you a six figure surprise.
This matters because commercial borrowers prepay far more often than they expect to. You sell the property. Rates move and a refinance makes sense. A partner wants out. A balloon date approaches and the takeout lender will not cover the old loan. Every one of these situations can trigger the prepayment terms.
Why commercial lenders penalize early payoff
Commercial lenders price loans for a long expected life. They commit capital, do underwriting, and expect a stream of interest income over years. When you pay the loan off early, they get their money back sooner than planned, in a market where they may have to reinvest it at lower rates. The prepayment penalty compensates them for that loss.
This is standard across the commercial lending world, not a quirk of one lender or one loan type. Bank loans, life company loans, and conduit loans all carry some version of it. The difference is not whether a penalty exists. It is how the penalty is calculated and when it applies.
Yield maintenance: the most common structure
Yield maintenance is the most common prepayment penalty on commercial loans. The idea is straightforward: if you pay off the loan early, you owe the lender the interest they would have earned if the loan had run to its normal term, adjusted to current market rates.
In practice, the calculation compares the interest rate on your loan to the current yield on a comparable government security. If rates have fallen since you borrowed, the difference is larger and the penalty is larger. If rates have risen, the penalty shrinks, sometimes to a floor set in the loan documents.
Two things about yield maintenance surprise borrowers. First, the penalty applies even when you are selling the property, not just when you refinance. The lender does not care why you are paying off. The trigger is the payoff itself. Second, the penalty can decline over the life of the loan, because fewer months of interest remain to make up. A payoff in year two costs far more than a payoff in year nine.
Before you model a sale or a refinance, ask your loan servicer for a current payoff quote that includes the prepayment amount. Do not estimate it yourself. Servicers run the actual contractual calculation, and the number is rarely what borrowers guess.
Defeasance: replacing the loan instead of repaying it
Defeasance is a second way to get out of a commercial loan early, and it works differently from a cash penalty. Instead of paying a fee, you substitute the loan with a portfolio of government securities that pays the lender the exact payments the loan would have produced. The lender keeps its scheduled income. You get released from the loan.
Defeasance is common on larger securitized loans. It has some real advantages: it avoids a negotiated penalty, and it is a defined contractual path rather than an argument. But it has real costs too. The securities purchase can be expensive, especially when rates have fallen. Legal and administrative fees are higher than a simple payoff. And the process takes time, typically weeks of coordination between your team, the servicer, and the securities provider.
Defeasance is almost never a do it yourself exercise. It requires servicer approval, a legal opinion, and a custodian for the securities. If your loan offers defeasance as an option, start the process well before your target closing date.
Stepdowns: penalties that shrink on a schedule
A stepdown prepayment penalty is the simplest of the three structures. The loan documents set a percentage penalty that declines over time. A common pattern is a higher penalty in the early years that steps down each year until it reaches zero or a small floor near the end of the term.
Stepdowns are attractive because the number is knowable in advance. You can look at the schedule and compute the penalty for a payoff in any given year. There is no interest rate calculation and no securities purchase. What you see is what you pay.
The catch is that stepdown penalties in the early years can still be substantial. Before you assume a stepdown is cheap, run the percentage against your actual balance. On a large loan, even a small percentage is real money.
Stepdowns often pair with a lockout period, a window at the start of the loan during which you cannot prepay at all, at any price. If your loan has a lockout, no penalty calculation matters during that window. The door is simply closed.
Lockout periods and partial prepayment limits
Many commercial loans restrict prepayment entirely for the first one to three years. During the lockout, an early payoff is not expensive. It is unavailable. Borrowers who plan to hold a property for only a couple of years sometimes discover this after they have already committed to a sale.
Even after the lockout, many loans limit how you can prepay. Some allow a full payoff only. Some allow partial prepayments up to a capped amount per year. Some charge the penalty on a partial prepayment exactly as they would on a full one. If your strategy involves paying down a portion of the balance, read the partial prepayment section of your note. It is one of the least read and most expensive clauses in commercial lending.
How prepayment terms change your planning
Once you know the structure, the planning follows. If your loan carries yield maintenance, every potential refinance has to clear the penalty hurdle, not just beat the rate. If it offers defeasance, large payoffs need a longer runway and specialist help.
Model the exit before you sign the loan, not when you want out. A loan with a lower rate and a heavy prepayment penalty can be more expensive than a loan with a slightly higher rate and a friendlier exit. The right comparison is the total cost of the loan over your actual expected hold period, penalty included.
When a refinance is the reason you are looking at the exit, the timing pressure is real. For how to think through an early refinance decision, read: How to Refinance a Commercial Loan Before the Balloon Hits.
Negotiating before you sign
Prepayment terms are negotiable at origination, and they are much harder to change afterward. Borrowers with leverage, a strong property, a large loan, competing term sheets, can often negotiate a shorter lockout, a lower stepdown schedule, or a defeasance option in place of yield maintenance. Ask for the prepayment language in the term sheet stage, when you still have the option to walk.
Pay particular attention to the penalty on a sale versus a refinance. Some lenders will agree to waive or reduce the penalty if the loan is assumed by the buyer rather than paid off. An assumable loan with a qualified buyer can save the penalty entirely, which is worth raising before the documents are final.

The bottom line
Prepayment penalties are not fine print. They are a core economic term of your commercial loan, and they determine when you can sell, when you can refinance, and what either move will actually cost. Know your structure: yield maintenance, defeasance, or stepdown. Know your lockout. Get a real payoff quote from the servicer before you model anything.
