Loan term vs amortization period: why a 5-year loan can have a 20-year schedule

Two numbers that answer different questions

The term answers: when does the lender get all its money back? On that date, the maturity date, whatever is still owed is due. The amortization period answers: how big is each payment? It is the number of years over which the principal would be repaid if the payments simply continued until the balance reached zero.

Most business loans set the two equal. An equipment loan repaid over five years matures in five years, and the last regular payment clears it. But a lender can calculate payments on a longer schedule than it is willing to lend for. A bank that writes a loan on commercial property with a five-year term on a 20-year schedule is saying two things: the payment should be affordable, as if the loan ran 20 years, and the bank wants to look at the loan again in five. The glossary entry on amortization vs maturity gives the short definitions.

Amortization sets what you pay each month. The term sets when you have to find the rest.

How a balloon arises

On a level-payment loan, the early payments are mostly interest, and principal comes down slowly at first. The longer the schedule, the slower it comes down. So when a long schedule is cut short by an early maturity, most of the principal is still there.

A worked example in plain numbers, for every 1,000,000 borrowed at the same interest rate throughout. The payment and the balance at each point depend only on the schedule.

Read across the 20-year row. After five years of payments, the business still owes about 875,000 of every 1,000,000 it borrowed. If the loan matures at year five, that is the balloon. It is not a penalty or a surprise; it is the arithmetic of the schedule. What makes it a risk is that it must be repaid, usually by refinancing, on a date fixed years in advance, whatever rates, property values, the business's results and lenders' appetite look like on that date.

Why a longer schedule raises capacity

Lenders size term debt on debt service coverage: cash flow available for debt service divided by the year's payments. Conventional bank lenders commonly look for at least 1.25x. A smaller payment per dollar borrowed means more dollars can be borrowed for the same cash flow.

Continuing the example: a business with cash flow available for debt service of 500,000, borrowing from a lender that needs 1.25x, can carry payments of 400,000 a year. On a ten-year schedule, that supports a loan of about 2,750,000. On a 20-year schedule, about 3,990,000. On a 25-year schedule, about 4,320,000. The business and the rate have not changed. The schedule alone has moved capacity by more than half.

That is why owners and buyers push for longer amortization, and why lenders tie the schedule to the collateral. A lender gives a long schedule where the collateral outlasts it, as land and buildings do. It gives a short one where the collateral wears out or has no value apart from the business, as with equipment and goodwill. The capacity a long schedule adds is borrowed against the collateral's life, and a lender will not lend beyond it. How much debt a business can carry walks through the full sizing.

How lenders set term and amortization by collateral

SBA 7(a) loans are the main exception to the balloon: they fully amortize over their maturity. A loan financing several things at once, say a building, equipment and goodwill, gets a blended maturity weighted by what each piece of the loan pays for. From 1 October 2026 under SOP 50 10 8.1, change-of-ownership loans amortize over no more than 10 years except the real estate share, so the goodwill in an acquisition cannot be stretched onto a longer schedule by pairing it with other assets. The SBA 7(a) vs 504 comparison and 504 vs conventional mortgage cover the real estate choice in more depth.

Longer SBA schedules come with a prepayment cost of their own: on 7(a) loans of 15 years or more, prepaying more than 25% in any of the first three years costs 5% of the prepaid amount in year one, 3% in year two and 1% in year three. A bank loan with a balloon is shorter, but its own prepayment terms may run to maturity.

Planning for the maturity

The short term is the lender's option to look at the loan again. For the owner it is a date on which a large balance must be refinanced, and the refinancing is underwritten from scratch: current results, current rates, current collateral values. A business whose earnings dipped the year before maturity, or whose rate on the new loan is higher than on the old one, may find the balance it owes is more than a new lender will lend.

• Start early. Put the maturity date on the calendar when the loan closes, and start the refinancing well before it, with a full year of results the new lender can underwrite. Refinancing before a balloon maturity sets out the sequence.
• Test the balloon on day one. Before signing, run coverage on the balance due at maturity at a higher rate. If that refinancing would not work on today's earnings, the structure depends on growth.
• Ask the current lender first. An extension or renewal with the existing lender is often simpler than a new loan. See maturity extensions with your current lender.
• Consider matching term and schedule. A fully amortizing loan, SBA or conventional, costs a higher payment but removes the refinancing. For a long hold, that trade is often worth it.
• Watch interest-only on top. An interest-only period on a loan that already has a balloon makes the balloon larger. The interest-only vs amortizing comparison shows how.

Transparent's financing model shows the balance at every maturity date under each structure offered, alongside coverage in each year, so the refinancing is visible before the loan closes. It is part of the lender package, and the lender book includes lenders that write both balloon and fully amortizing structures.
