How commercial balloon loans work in the United States
Commercial real estate (CRE) loans and small business term loans in the United States frequently use a partially amortizing balloon structure. Rather than fully amortizing the debt over the contractual term, lenders calculate monthly debt service payments using a long-term amortization period, typically 20, 25, or 30 years. However, the loan note matures after a much shorter duration, such as 3, 5, 7, or 10 years.
This structure, commonly referred to as a 5/25 or 10/30 commercial loan, keeps regular debt service affordable for the borrowing business while limiting the lender's interest rate exposure. Because early payments primarily cover interest, only a small portion of the loan balance is amortized over the initial years. At the maturity date, the entire remaining principal balance falls due in a single lump-sum balloon payment.
Borrowers typically exit the balloon by refinancing into a new long-term commercial loan, selling the commercial real estate asset, or paying down the balance from accumulated corporate cash reserves.
Commercial balloon methods: amortization schedule vs percentage balloon
Commercial lenders evaluate balloon structures in two primary ways:
1. Amortization schedule (partial amortization): The monthly principal and interest (P&I) payment is calculated over an extended amortization period (such as 25 years or 300 months). The loan agreement specifies that the note matures at year 5 (month 60). The balance remaining on the amortization schedule at month 60 is the balloon payment.
2. Specified balloon percentage or fixed lump sum: Common in asset financing and private commercial lending, where the borrower agrees to pay a predetermined residual (such as 25% or 30% of the loan amount) at maturity. The regular monthly payments are sized to cover interest and the exact principal required to reduce the loan to that target balance.
Both methods lower monthly debt service but leave a significant refinancing or liquidity obligation at maturity.
Worked example: $500,000 commercial loan over 5 years with 25-year amortization
Borrow $500,000 at 7.0% annual interest over a 5-year loan term with a 25-year amortization schedule, repaid monthly, with a 1.5% origination fee of $7,500 deducted from proceeds. You receive $492,500.00. The regular monthly payment is $7,533.90 for 60 months, paying $44,189.24 of principal and $167,844.52 of interest over the term. At month 60, the final balloon payment due is $455,810.76, which is 91.16% of the initial principal.
In total you repay $667,844.52 including the final balloon payment. With the $7,500 origination fee, the total cost of borrowing is $175,344.52, which is 35.07% of the amount borrowed, giving an estimated annualized cost of 7.37%. After 12 months you owe $492,350.93, having paid $34,757.68 in interest in the first year.
By comparison, fully amortizing $500,000 over five years without a balloon would require a monthly payment of $9,900.60. The balloon structure saves $2,366.70 in monthly cash flow, but incurs $73,808.56 in additional interest because the outstanding note balance stays elevated throughout the term.
Comparing monthly cash flow savings to extra interest cost
The primary benefit of a commercial balloon note is immediate cash flow conservation. Saving $2,366.70 per month allows a business to reinvest capital into operating expansion, payroll, marketing, or property improvements to increase net operating income (NOI).
However, this cash flow comes at a cost. Because interest accrues on the outstanding balance, and principal amortizes very slowly in the early years of a 25-year schedule, the borrower pays $167,844.52 in interest over 5 years compared to $94,035.96 on a fully amortizing 5-year loan. Business owners and real estate investors must verify that the capital freed up yields a higher return than the extra interest expense.
Exit strategies for paying off the balloon note
Because commercial balloon payments routinely exceed 90% of the original loan balance, planning a reliable exit strategy is essential:
1. Commercial refinancing: Applying for a new commercial real estate loan or SBA 504/7(a) refinance loan 6 to 12 months before maturity. Lenders will evaluate the property debt service coverage ratio (DSCR), current loan-to-value (LTV), and market interest rates.
2. Property disposition: Selling the commercial building or facility on the open market, using proceeds to satisfy the balloon and capturing the property appreciation as equity.
3. Cash payoff: Utilizing retained business earnings or partner capital contributions to pay off the balance without incurring new debt.
Prepayment penalties and step-down structures
Many commercial balloon loans include prepayment penalties to guarantee lender yield. Common structures include step-down penalties (such as 5-4-3-2-1% over a 5-year term), yield maintenance, or defeasance. If you plan to sell or refinance before maturity, verify the penalty formula in your loan documents and enter the prepayment percentage in the calculator to evaluate early settlement costs.

Inputs for the commercial loan balloon payment calculator

CALCULATOR QUESTIONS
US commercial loan balloon payment calculator questions
What is a commercial loan balloon payment?
A commercial balloon payment is the lump-sum balance due at the end of a commercial loan term. The monthly payments are calculated using a 20- to 30-year amortization schedule to keep debt service low, but the note matures after 3, 5, 7, or 10 years, requiring the remaining balance to be paid in full.
Why do commercial banks prefer balloon loans?
Commercial banks prefer balloon loans because they limit their exposure to long-term interest rate fluctuations and allow them to re-evaluate the borrower's financial health, property performance, and market loan-to-value (LTV) every 3 to 10 years.
How is a balloon payment calculated on a 5/25 commercial loan?
On a 5/25 commercial loan, monthly payments are calculated based on a 25-year (300-month) amortization schedule. At month 60 (the 5-year maturity date), the lender calculates the remaining principal balance on the amortization table, which becomes the final balloon payment.
What happens if a borrower cannot refinance a commercial balloon loan?
If a borrower cannot refinance or pay off the balloon payment at maturity, the loan goes into technical default. The lender may grant a short-term extension for an additional fee, or they may initiate foreclosure proceedings on the commercial collateral. Borrowers should begin refinancing discussions 6 to 12 months prior to note maturity.
What is the difference between loan maturity and amortization term?
Loan maturity is the date when the entire loan balance must be settled in full (e.g. 5 or 10 years). The amortization term is the theoretical timeframe over which payments are calculated (e.g. 25 or 30 years) to establish manageable monthly payments.
How does a commercial balloon loan affect DSCR?
Because monthly payments are calculated on a longer 20- or 25-year amortization schedule rather than a short term, the monthly debt service is much lower. This improves the property debt service coverage ratio (DSCR), making it easier for commercial properties to qualify for financing based on net operating income (NOI).
How do fees affect the estimated annualized cost?
The estimate uses the net cash you receive after any fees paid or deducted at completion, then compares it with the scheduled repayments and balloon. It is an illustrative cash-flow estimate, not a lender quote or a statutory APR determination. Confirm the applicable disclosure with your lender.
