Can I enter a balloon percentage instead of an amount?

Convert the percentage to dollars first (loan × percent) and enter that figure.

What if I refinance before the balloon is due?

Use the planned payoff month as your term to approximate monthly payments until refinancing.

Plan monthly payments when a lump-sum balloon is due at the end of the term.

Enter the loan amount, APR, term, and balloon amount due at maturity.
We adjust the amortization to reflect the balloon and compute the reduced monthly payment.
Review total interest, total paid, and the balloon you need to cover at the end.

We use the amortization formula but subtract the balloon (discounted back to today) from the financed balance.

Total paid = monthly payments × number of payments + the balloon check you write at the end.

Monthly r = APR ÷ 12
Payments = Years × 12
Payment = [(P − B / (1+r)^n) × r] ÷ [1 − (1+r)^{-n}]
Total paid = Payment × n + Balloon

Comparing balloon mortgages against fully amortizing options.
Planning a business loan where you expect to refinance or sell an asset before maturity.
Stress-testing cash needs when a large payoff is looming.

Balloon loans typically assume you’ll refinance or sell—plan that exit early.
Include closing costs or refinance fees separately when evaluating total cost.
Check if the lender has yield maintenance or prepayment penalties when paying the balloon early.
Assumes fixed-rate payments until the balloon date.
Does not include taxes, insurance, fees, or prepayment penalties.
Balloon amount is treated as a lump sum—no partial amortization of that portion is modeled.

See monthly payments and the lump-sum payoff for balloon loans by entering APR, term, and balloon size.

Great for real estate investors and business owners who need to map out cash flow before refinancing or selling.
