Balloon Mortgage Calculator
Balloon loans amortize on a longer schedule (often 30 years) but require the entire remaining balance as a single payment on a much earlier date. See the payment, the balloon, and the principal you've reduced by then.

Reading the number
A balloon loan amortizes the payment as if the term were 30 years, but the entire remaining balance is due at year 7. Until then your monthly payment looks like a normal mortgage; on the balloon date you must refinance, sell, or pay the remaining balance in full.
Use balloon loans when you have a clear exit (sale, refinance, takeout commitment). The biggest risk is a refinance market that's worse than today — interest rates, credit standards, or property value can all move against you before the balloon hits.
How to Use
- Enter the loan amount and rate.
- Enter the amortization period — typically 30 years (this drives monthly payment size).
- Enter the balloon date — the year the entire remaining balance is due.
- Read the balloon amount and plan an exit (sell, refinance, payoff) before that date.
Frequently Asked Questions
Where do balloon mortgages show up?
Most often in seller-carry deals, commercial real estate, hard money / private lending, and some non-QM products. They're rare in conventional residential lending today.
What happens if I can't refinance the balloon?
You're either selling the property or defaulting. That's why balloon loans should only be used with a credible exit plan — and ideally a backstop (cash reserve, second-lien capacity, equity headroom).
How is a balloon different from interest-only?
An IO loan eventually fully amortizes after the IO period — the full balance gets repaid through monthly payments. A balloon requires the remaining balance as a lump sum on a fixed date. They're sometimes combined (interest-only with a balloon).
Can I make extra principal payments to reduce the balloon?
Yes, and it's often a smart hedge. Every extra dollar today reduces what you'll need to refinance or pay later, lowering refinance risk if rates rise or values drop before the balloon date.
