What Is Commercial Loan Amortization and Why It Matters

Commercial real estate mortgages differ significantly from residential loans. While residential loans often feature 30-year fixed terms, commercial loans typically feature shorter loan maturity terms (such as 5, 7, or 10 years) paired with a longer amortization schedule (such as 25 or 30 years). At maturity, the remaining principal balance must be paid off or refinanced via a "balloon payment." Calculating your monthly debt service and balloon payoff is essential for projecting cash flow and refinancing risk.

The Formula

M = P × [ r(1 + r)^n ] / [ (1 + r)^n − 1 ]
M:Monthly Principal & Interest Payment
P:Principal Loan Amount ($)
r:Monthly Interest Rate (Annual Rate / 12)
n:Total Amortization Payments (Amortization Years × 12)

A Real Example

You secure a $2,000,000 commercial mortgage at 6.5% interest, structured on a 25-year amortization schedule with a 10-year balloon maturity. Your monthly payment is $13,496 ($161,952/year). Over the first 10 years, you pay $1,619,520 total ($1,152,192 in interest, $467,328 in principal). At year 10, your remaining balloon balance due is $1,532,672.

Frequently Asked Questions

What is a balloon payment in commercial real estate?

A balloon payment is a lump-sum principal balance due at the end of a loan term when the loan's maturity period (e.g. 10 years) is shorter than its amortization schedule (e.g. 25 years). Investors typically refinance or sell the property before the balloon date.

What amortization period is standard for commercial mortgages?

Most commercial real estate loans use a 25-year amortization schedule. Primary, institutional assets may qualify for 30-year amortization, while older or special-purpose properties may be restricted to 20 years.

How does interest rate impact commercial debt service?

Because commercial loan amounts are large, even a 0.5% interest rate change significantly shifts annual debt service, directly impacting your DSCR and Cash-on-Cash returns.

Are commercial loan interest rates fixed or variable?

Commercial loans can feature fixed rates for 5 to 10 years, or variable/floating rates tied to SOFR or Prime. Hybrid loans often fix the rate for the initial 5 or 7 years before resetting.
