Balloon Mortgage Calculator
Estimate a balloon mortgage payment and lump sum, then optionally compare a future home sale or refinance amount with the payoff, cash gap, and estimated replacement payment.
Method and assumptions
Figur calculates the monthly payment over the stated amortization period, applies those payments through the earlier maturity, and finds the remaining principal due as the balloon.
- The rate stays fixed and is divided by 12.
- Equal monthly payments use an amortization period longer than the loan's maturity.
- Remaining principal is due immediately after the stated final monthly payment.
- Estimated sale proceeds must be net of transaction costs; property value and a future sale are neither forecast nor guaranteed.
- The refinance comparison assumes the entered amount, rate, and term; it does not guarantee approval or represent lender terms.
- Taxes, insurance, escrow, points, fees, penalties, and refinancing costs are excluded.
Educational estimate, not a loan quote or financial advice. Confirm payment timing, rate changes, fees, maturity options, and every actual term with your lender.

Frequently asked questions
Why is there a balloon payment?
Regular payments are calculated over a longer amortization period than the loan's maturity, so the unpaid principal becomes due as a lump sum.
Is the balloon amount extra interest?
No. It is primarily the principal still unpaid at maturity; the calculator shows interest through that date separately.
What happens at maturity?
The contract may require payoff, sale, or refinancing. This estimate cannot predict approval or lender-specific options.
What does the exit-plan comparison assume?
Sale proceeds must be entered net of transaction costs. A refinance amount, rate, and term are planning assumptions—not approval, a property-value forecast, or lender terms.
