About the Balloon Payment Calculator
A balloon payment is a large lump sum due at the end of a loan term that is shorter than the amortization period. For example, a loan amortized over 30 years but with a 5-year term means you make normal monthly payments for 5 years, then must pay the entire remaining balance at once — the balloon payment.
Balloon loans are common in commercial real estate, land contracts, and some residential mortgages. They offer lower monthly payments during the loan term because the full principal is not repaid through regular payments. However, the borrower must be prepared to pay, refinance, or sell when the balloon comes due.
This calculator shows your monthly payment, the balloon amount due, total interest over the term, and what percentage of the loan you actually pay off before the balloon date. The term comparison table lets you see how different balloon periods affect the lump sum, helping you plan your exit strategy.
When This Page Helps
Balloon loans carry significant risk — if you cannot refinance or sell when the balloon comes due, you could lose the property. This calculator quantifies that risk by showing exactly how much you will owe. It helps you plan ahead, evaluate whether a balloon structure makes financial sense, and set realistic expectations about the lump sum commitment.
How to Use the Inputs
- Enter the property or loan price.
- Subtract any down payment.
- Set the interest rate.
- Choose the amortization period (payment calculation basis).
- Set the balloon term (when the lump sum is due).
- Optionally add extra monthly payments to reduce the balloon.
- Review the balloon amount and compare different terms.
Formula used
Monthly Payment M = L × [r(1+r)^N] / [(1+r)^N − 1] where L = loan amount, r = monthly rate, N = amortization months. Balloon Payment = remaining balance after B months of payments, where B = balloon term in months.Example Calculation
Result: $1,439/mo — $224,735 balloon due after 5 years
A $240,000 loan at 6% amortized over 30 years has a $1,439 monthly payment. After 5 years (60 payments), only $15,265 of principal is paid off — leaving a $224,735 balloon payment. You will have paid $71,094 in interest during those 5 years.
Tips & Best Practices
- Have a clear exit strategy — refinance plan, sale timeline, or savings plan for the balloon.
- Extra monthly payments directly reduce the balloon amount and total interest.
- Longer balloon terms reduce the lump sum but increase total interest paid.
- Interest rates may be higher when you need to refinance — factor potential rate increases into your plan.
- Some balloon loans include a reset option allowing conversion to a fixed-rate at maturity.
- Commercial balloon loans often have 5-7 year terms — plan for refinancing costs.
Why Balloon Loans Feel Affordable Up Front
The regular payment is based on a long amortization period even though the actual loan term ends much sooner. That gap is why the monthly payment can look manageable while a very large balance is still outstanding when the balloon comes due.
Planning the Exit Strategy
Most borrowers handle a balloon by refinancing, selling the property, or bringing cash to closing at maturity. The real planning question is whether your likely property value, credit profile, and market rates will support that exit when the term ends.
Stress-Testing the Risk
Run several balloon terms and extra-payment scenarios. If the remaining balance is still too large to refinance comfortably after a few years of payments, the structure may be too aggressive for the transaction.

Methodology
This page calculates the regular payment from the long amortization period, then stops the amortization schedule at the shorter balloon term and reports the remaining principal as the balloon amount due. Optional extra payments are applied to principal before the balloon date so the user can see how they shrink the final lump sum.
It is a planning worksheet rather than a commitment-letter replica. Actual balloon notes can include rate resets, extension options, refinancing costs, or lender-specific default terms that are outside this simplified model.

Frequently Asked Questions
You must refinance the remaining balance, sell the property to pay it off, or negotiate a loan modification with the lender. Failing to pay typically results in default and potential foreclosure.
Balloon loans may offer lower rates than fully amortizing loans, making them attractive for investors planning to sell before maturity, borrowers expecting a large future payment, or situations where long-term financing is unavailable. The tradeoff is refinancing risk at the balloon date.
Very little in the early years. On a 30-year amortization with a 5-year balloon, only about 6–8% of the principal is paid off. With a 7-year term, roughly 9–12% is paid. The majority of early payments go to interest.
Yes, if the loan allows prepayment without penalty. Every extra dollar goes to principal, directly reducing the balloon amount. Even modest extras can make a meaningful difference.
No. A balloon loan makes regular principal and interest payments (just not enough to fully repay). An interest-only loan pays zero principal, so the entire loan amount is due at maturity.
Residential balloons are typically 5 or 7 years. Commercial balloons range from 3 to 10 years. The amortization period is usually 15-30 years, resulting in lower payments but a large remaining balance at term.
