You just landed the contract that lets you kill your business loan two years early. You call the lender for a payoff quote, expecting a pat on the back — and the number comes back thousands of dollars higher than your remaining balance. That gap is the prepayment penalty: the price of ending the lender's interest income ahead of schedule. On some loans it is zero. On others it can wipe out every dollar of interest you hoped to save, and on a commercial mortgage with yield maintenance it can be the single largest check your business writes all year.
This guide walks through every major prepayment structure a small-business borrower meets: the SBA 7(a) subsidy recoupment fee with its 5-3-1 schedule, the SBA 504's declining debenture penalty, and the lockout periods, step-down schedules, yield-maintenance clauses, and make-whole provisions in conventional loans. You will learn the exact math behind each one, how to decide whether paying early still wins, and how to book the penalty on your own books.
Why Lenders Charge You for Paying Early
A lender prices your loan expecting a full term of interest payments. When you prepay — by refinancing into a cheaper rate, selling the business, selling the mortgaged property, or simply paying cash ahead of schedule — the lender gets its principal back but loses the interest it counted on, and must re-lend that money at whatever rates exist now. If rates have fallen, the replacement loan pays less. The prepayment penalty compensates for that lost yield.
Not every loan has one. Competitive pressure over the past decade has pushed many lenders to drop or limit prepayment penalties on ordinary term loans and lines of credit. But three corners of the market still charge them almost universally: SBA loans, where the penalty is set by federal regulation rather than the lender, and commercial real estate loans, where long fixed-rate terms make the lender's reinvestment risk the greatest. Always check your note and loan agreement before you plan an early payoff — the penalty clause, if any, lives there.
The SBA 7(a) Prepayment Penalty: the 5-3-1 Rule
The SBA 7(a) program charges what the regulations call a subsidy recoupment fee. The name tells the story: the government guarantees up to 75 percent of these loans, and an early payoff deprives the SBA of the fee income it expected over the full term. Two things make this penalty unusual. First, it is owed to the SBA, not to your lender — lenders are prohibited from layering their own prepayment penalty on top of a 7(a) loan. Second, it applies only when three conditions are all true at once.
The three conditions that trigger it
Under 13 CFR 120.223, the fee applies only if:
- The loan's original maturity is 15 years or longer. Most 7(a) working-capital loans run 10 years and equipment loans run 10 years, so this condition alone exempts the majority of borrowers. It is almost exclusively long-term real estate 7(a) loans, with maturities up to 25 years, that qualify.
- You voluntarily prepay 25 percent or more of the outstanding balance within a single 12-month period. Involuntary paydowns, such as insurance proceeds applied after a casualty, do not count. And the 25 percent test is per year, not cumulative.
- The prepayment happens within the first three years after the initial disbursement. Prepay any amount in year four or later and there is no fee at all.
Miss any one of these and you owe nothing. A 10-year 7(a) loan can be prepaid in full on day one with no penalty. A 25-year real estate loan prepaid 20 percent in year two also escapes, because the annual prepayment stays under the 25 percent line.
The 5-3-1 schedule
When all three conditions hold, the fee is a percentage of the amount you prepaid — not of the whole balance:
- Year 1: 5 percent of the prepaid amount
- Year 2: 3 percent of the prepaid amount
- Year 3: 1 percent of the prepaid amount
- Year 4 onward: no fee
Suppose you took a $1,000,000 7(a) real estate loan and sell the property eighteen months later, prepaying the full $950,000 balance. That is year two, so the fee is 3 percent of $950,000, or $28,500, paid to the SBA at closing. Had the sale closed six months later, still inside year three, the fee would have been 1 percent, or about $9,500 — a $19,000 difference for half a year of patience. This is why 7(a) borrowers planning a sale or refinance should map the disbursement anniversary dates before they sign anything.
The partial-prepayment escape hatch
Because the trigger is 25 percent or more in one year, borrowers who simply want to pay down faster can often avoid the fee entirely by staying under the line: prepay 20 percent of the balance this year and another 20 percent next year and no fee is ever owed, even inside the first three years. Confirm your lender measures the 25 percent the way you do — against the outstanding balance at the time of prepayment — before relying on it.
The SBA 504 Declining Penalty: Longer and Larger
SBA 504 loans, used to buy buildings, land, and heavy equipment, split your financing into two pieces: a bank's first-lien loan for about 50 percent and a Certified Development Company (CDC) debenture, fully guaranteed by the SBA and sold to investors, for about 40 percent. The prepayment penalty lives on the CDC debenture portion, and it is stricter than the 7(a) fee in every direction.
How the 504 schedule works
Under 13 CFR 120.940, the debenture carries a declining prepayment premium over the first half of its term: the first 10 years of a 20- or 25-year debenture, or the first 5 years of a 10-year debenture. The premium starts at the debenture's own interest rate and declines each year — by one-tenth per year on a 20-year debenture, by one-fifth per year on a 10-year debenture.
Concretely, if your 20-year debenture carries a 6 percent note rate, prepaying in year one costs about 6 percent of the remaining debenture principal. By year five the premium has fallen to roughly 3 percent, by year ten to a fraction of a percent, and from year eleven on it is zero. On a $400,000 debenture balance, a year-two exit at roughly 5.4 percent costs over $21,000 — and that is before the bank's first-lien loan, which carries its own separately negotiated prepayment terms that you must read independently.
Two 504 traps borrowers miss
First, the debenture pays investors on a semi-annual schedule, and a payoff requires accrued interest and servicing fees through the next payment date. Request your payoff quote from the CDC well before a planned sale or refinance so the stub interest does not surprise you at closing. Second, the 504 penalty is computed on the remaining principal, not just the prepaid amount the way the 7(a) fee is — a full payoff always prices against the whole balance. There is no 25-percent-style escape hatch here.
Conventional Loans: Lockouts, Step-Downs, Yield Maintenance, and Make-Whole
Conventional commercial loans — bank CRE mortgages, CMBS conduit loans, and larger term loans — do not follow a federal schedule. Each note negotiates its own structure, but nearly all of them assemble the same four building blocks.
Lockout periods: no prepayment at any price
A lockout period prohibits prepayment entirely for a set window after closing, commonly one to two years on bank loans and longer on securitized loans. During lockout you cannot pay the loan off even if you sell the property or refinance into cheaper debt — the lender simply refuses the payoff. Lockouts exist so the lender, or the investors who bought the loan, can count on a minimum run of payments. When shopping for a loan, treat the lockout length as a hard constraint on your exit plans, because no penalty payment buys your way out of it.
Step-down schedules: a declining fixed percentage
Once any lockout expires, many loans switch to a step-down (or stepdown) schedule: a fixed percentage of the outstanding balance that declines over time. A typical ten-year commercial mortgage might read 5-5-4-3-2-1-1-0-0-0, meaning 5 percent of the balance in years one and two, 4 percent in year three, and so on down to zero for the final years. Step-downs are predictable — you can price any exit date the day you sign — which is exactly why borrowers who expect to sell or refinance often negotiate for a step-down instead of the interest-rate-linked structures below.
Yield maintenance: the lender's lost interest, as a lump sum
Yield maintenance is the most expensive structure most borrowers ever meet, and the least intuitive. Instead of a fixed percentage, you owe the present value of the interest the lender would have earned had the loan run to maturity, discounted at a benchmark rate — usually the yield on a U.S. Treasury of comparable remaining maturity.
The formula, in words: take the loan's remaining scheduled interest payments, subtract the interest those same dollars would earn at the current Treasury rate, and discount the difference back to today. When market rates have fallen since you borrowed, the gap is large and so is the penalty. A simplified example shows the scale: on a $2,000,000 loan at 7 percent with five years left, if comparable Treasuries now yield 4 percent, the lender is losing roughly 3 percentage points of yield for five years — a penalty in the neighborhood of $250,000 to $300,000 after discounting. If rates had instead risen above your loan rate, the formula can produce zero, though most notes impose a floor such as 1 percent of the balance so the lender always collects something.
Because yield maintenance moves inversely with rates, the worst time to refinance a yield-maintenance loan is precisely when refinancing looks most attractive — right after rates drop. Before you celebrate a rate cut, price the penalty.
Make-whole provisions and defeasance
A make-whole provision is the general name for any clause that compensates the lender for its full expected interest; yield maintenance is one type of make-whole. Bond-style make-whole clauses, common in larger private placements, typically discount the remaining payments at Treasury plus a small spread, such as 50 basis points, which slightly reduces the penalty versus a pure Treasury discount rate.
Defeasance achieves the same economics without a cash penalty: instead of paying off the loan, you buy a portfolio of U.S. Treasury securities that replicates the loan's remaining payments, and the lender substitutes those bonds for your property as collateral. The loan technically stays alive until maturity while your property is released. Defeasance dominates in CMBS loans, where the securitization trust needs its cash flows to continue undisturbed. It is complex and carries consultant and legal fees of its own, so price the whole transaction — securities cost plus fees — against a straight yield-maintenance payoff before choosing.
The open period: your free exit window
Most commercial notes end with an open period — typically the last three to six months before maturity — during which you may prepay with little or no penalty. Find this date the day you close and calendar it: starting a refinance a few weeks inside the open period instead of a few weeks before it can save the entire penalty.
Should You Still Pay Early? The Break-Even Math
A penalty does not automatically mean waiting wins. Run three numbers before you decide.
Interest savings versus penalty. Add up the interest you would pay over the remaining term and subtract the penalty plus any closing costs on replacement financing. If you owe $200,000 at 9 percent with three years left, the remaining interest is roughly $29,000; a 3 percent step-down penalty of $6,000 still leaves you about $23,000 ahead by paying now. But if that same loan carried yield maintenance priced at $25,000, the savings nearly vanish.
Cash flow and opportunity cost. Paying off a loan frees monthly payments for other uses, but it also drains cash you might need for payroll, inventory, or emergencies. Compare the loan's after-tax interest rate against what the cash earns elsewhere. With business loan rates often well above safe yields, the payoff usually wins on pure return — but only if the business keeps a comfortable reserve afterward.
Your future borrowing profile. Reducing debt can improve your debt-service coverage ratio and make the next loan cheaper or larger. Lenders look kindly on borrowers who paid early even when it cost a fee. Weigh that against the penalty: sometimes the cheapest path to your next financing is a slightly expensive exit from this one.
How to Book a Prepayment Penalty
For tax purposes, the IRS treats a prepayment penalty as additional interest — a cost of borrowing deductible under Section 163 in the year you pay it, when the payoff closes the loan for good. If the penalty is part of a refinancing rather than a final payoff, the treatment can shift toward capitalizing and amortizing the cost, so confirm the facts with your tax preparer before filing. For your books, record the penalty as an interest expense, not as part of the loan principal and not capitalized into any asset. In plain-text accounting the payoff entry looks like this:
2026-11-15 payoff "Early payoff of SBA 7(a) loan in year 2"
Assets:Checking -82,400.00 USD
Liabilities:Business-Loan:SBA-7a 80,000.00 USD
Expenses:Interest:Prepayment-Penalty 2,400.00 USDThe checking outflow is the full payoff quote — principal plus the 3 percent year-two fee on the $80,000 prepaid — while the liability clears at its carrying amount and the fee lands in its own expense account where it flows straight to your income statement. If you are new to this style of bookkeeping, the introduction to Beancount covers accounts, transactions, and balance assertions from zero. Keeping the penalty in a dedicated subaccount also makes tax time trivial: the deductible amount is one account balance, already separated from ordinary interest.
Your Pre-Signing and Pre-Payoff Checklist
Penalties are cheapest to manage before they bind you. When signing a new loan, ask whether any prepayment penalty applies, which structure it uses, how long any lockout runs, when the open period starts, and whether partial prepayments under a threshold escape the fee — then get the answers as note language, not conversation. When planning a payoff, request a written payoff quote early, map it against your disbursement anniversaries on SBA loans, price yield maintenance at current Treasury rates rather than the rate you remember from closing, and run the break-even math with after-tax numbers. The borrower who does this homework never meets the penalty as a surprise at the closing table.
