Calculate balloon loan payments with large final payment — see monthly, balloon and total interest.
Enter values above and click Calculate — results will appear here with the formula explained.
A balloon loan amortizes the principal net of the final large payment as though it were a fully amortizing loan, then adds interest on the balloon balance that sits untouched until maturity. Monthly payment therefore roughly equals the amortizing payment on principal minus balloon plus balloon times monthly rate, which noticeably lowers the payment at the cost of a large terminal liability. The calculator separates the regular amortizing portion from the balloon interest so the trade-off is legible: for a $300,000 purchase with a 30% balloon over 7 years at 6.5%, payment drops by hundreds but $90,000 remains due at once.
Balloon structures suit short horizons where a sale or refinance is planned before the balloon, and they punish holders who remain past maturity without a plan. Test how the payment moves with balloon percentage — each 10-point increase in balloon share reduces payment modestly but linearly increases the maturity cliff — and ensure savings or equity clearly cover the lump sum.

Formula: Balloon = P*balloonPct; Payment amortizes P-balloon over n, balloon due at end
Balloon Payment Calculator computes calculate balloon loan payments with large final payment — see monthly, balloon and total interest. Formula: Balloon = P*balloonPct. Example: With $30k, 6% for 5y, 30% balloon $9k: monthly about $438 vs $579 fully amortizing, saving $141/mo but $9k due at end.
