How commercial loans with balloon payments work
A commercial loan with a balloon payment is a partially amortising debt facility. Rather than repaying the entire debt to zero over the contract term, regular instalments are calculated on a longer amortisation profile, typically 20 to 25 years. However, the loan contract itself matures much earlier, commonly after 3, 5, or 10 years.
Because instalments are based on a 25-year schedule, the monthly commitment is significantly lower than a standard 5-year fully amortising loan. However, because early payments consist largely of interest, only a small portion of the principal balance is paid down. At maturity, the entire remaining loan balance falls due immediately as a lump sum balloon payment.
Commercial lenders use balloon structures extensively for commercial real estate, trading business acquisitions, and working capital loans where predictable, manageable monthly cash flow is required during the initial holding or trading period.
Balloon calculation methods: amortisation profile vs fixed lump sum
Commercial facilities structure balloon payments in one of two ways:
1. Amortisation profile: The lender calculates payments using an extended amortisation period (for instance 25 years or 300 months) at the quoted interest rate. The monthly instalment pays interest plus a small amount of principal. When the loan term ends at year 5 (month 60), the remaining balance on the amortisation table becomes the balloon payment.
2. Percentage or fixed balloon: In asset finance or structured commercial loans, a pre-agreed residual value or balloon percentage (such as 20% or 30%) is set. The regular payments are sized to cover all interest plus only enough principal to bring the balance down to the agreed balloon level at maturity.
Both structures create lower monthly payments during the term but leave a substantial liability that must be settled at maturity.
Worked example: £250,000 over five years on a 25-year amortisation profile
Borrow £250,000 at 7.5% nominal over a five-year loan term with a 25-year amortisation profile, repaid monthly, with a 1.5% arrangement fee of £3,750 deducted from the loan. You receive £246,250.00. The regular monthly repayment is £1,847.48 for 60 months, paying £20,668.63 of principal and £90,180.05 of interest over the term. At month 60, the remaining balloon payment due is £229,331.37, which is 91.73% of the initial loan.
In total you repay £340,180.05 including the final balloon payment. With the £3,750 arrangement fee, the total cost of borrowing is £93,930.05, which is 37.57% of the amount borrowed, giving an estimated annualized cost of 8.17%. After 12 months you owe £246,460.23, having paid £18,629.96 in interest in the first year.
By comparison, fully amortising £250,000 over five years without a balloon would require a monthly repayment of £5,009.49. The balloon structure saves £3,162.01 in cash flow each month, but incurs £39,610.82 in additional interest because the loan balance remains high throughout the holding period.
Cash flow savings vs long-term interest cost
The primary advantage of a balloon commercial loan is immediate cash flow flexibility. In our worked example, the business frees up more than £3,100 per month, which can be reinvested into operational expansion, stock, hiring, or property refurbishment.
However, this cash flow relief carries an interest penalty. Because interest is charged on the outstanding balance every month, and the balance declines very slowly, total interest on the balloon loan is £90,180.05 over 5 years, compared to £50,569.23 on a fully amortising 5-year loan. Borrowers must evaluate whether the cash flow benefits outweigh the £39,610.82 in extra interest costs.
Exit strategies: handling the final balloon payment
Because balloon payments frequently represent 80% to 92% of the original borrowing, businesses must have a credible exit strategy agreed well in advance of maturity:
1. Commercial remortgage or refinancing: The most common exit strategy. At month 54 to 58, the borrower applies for a new commercial mortgage with an alternative lender or rolls the facility into a new term with the incumbent bank.
2. Asset or property sale: If the loan financed commercial property or development assets, the borrower sells the property on the open market, using proceeds to clear the balloon and banking the surplus equity.
3. Cash accumulation: If trading cash flow has been strong, the accumulated retained profits can be used to pay down the balloon in cash without taking on replacement debt.
Early settlement and refinancing penalties
Many commercial balloon loan contracts include early repayment charges (ERCs), typically 1% to 3% of the outstanding balance if the loan is redeemed before a specified date. If your business plans to refinance before year 5, check whether the contract has a stepped ERC structure (such as 3% in year one, 2% in year two, 1% in year three) and factor that penalty into your refinancing appraisal.

CALCULATOR QUESTIONS
UK commercial loan balloon payment calculator questions
What is a commercial loan balloon payment?
A commercial loan balloon payment is a large lump sum due at the end of a loan term. The monthly payments are calculated as if the loan were to last 20 to 25 years, but the contract ends after 3, 5, or 10 years, leaving the remaining principal balance to be paid in full.
Why do commercial lenders use balloon payments?
Commercial lenders use balloon payments to manage long-term interest rate risk and reassess the borrower and collateral periodically. It allows lenders to offer competitive, lower monthly repayments while ensuring they can re-underwrite or re-price the loan every 3 to 10 years.
How is the balloon payment calculated on a 25-year amortisation profile?
The calculator first determines the monthly payment required to fully pay off the loan over 25 years (300 months) at your quoted rate. It then projects the loan balance forward for the actual loan term (such as 60 months). The remaining principal balance at month 60 is the balloon payment.
What happens if I cannot pay the balloon payment when it is due?
If you cannot refinance, sell the property, or pay the balloon in cash, the loan goes into default. The lender may agree to a temporary facility extension for an additional fee, or they may enforce their security by appointing a receiver or repossessing the commercial asset. Start refinancing preparations at least 6 to 12 months before maturity.
Can I make overpayments to reduce the final balloon payment?
Yes, many commercial lenders permit capital reductions, though some restrict annual overpayments to 10% of the balance without penalty. Any principal overpayment directly reduces the final balloon sum due at maturity.
What is the difference between loan term and amortisation term?
The loan term is the contractual duration of the loan facility until full repayment or balloon settlement is required (e.g. 5 years). The amortisation term is the theoretical timeline used to spread out regular monthly payments (e.g. 25 years) to keep them manageable.
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.
