How this calculator works
The monthly payment is calculated as if the loan ran the full amortization period.
The balloon is the remaining balance after the regular payments through the balloon date.
Formulas
Balance after k payments = L(1+r)^k − PMT × ((1+r)^k − 1) ÷ r Assumptions & limits
- Fixed rate; balloon paid on the due date in addition to the final regular payment being made.
- Plan your exit (refinance or sale) well before the balloon date. Refinancing depends on future rates and values.
- Default interest rates are illustrative examples, not quotes or current market rates (last reviewed 2026-10-18). Enter the rate from your lender.

Frequently asked questions
What happens if I can't pay the balloon?
You would need to refinance, sell, or negotiate an extension with the lender. If none is possible, the lender may pursue foreclosure, which is why balloon loans need a clear exit plan.
Are balloon mortgages common in seller financing?
Yes. Seller-financed deals often use a 30-year amortization with a 3–7 year balloon so the seller is paid in full sooner.
