Balloon Payment Calculator

Calculate balloon payments on loans with shorter terms than amortization periods. See the lump sum due, interest paid, and compare different balloon terms.

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.

Why Use This Balloon Payment Calculator?

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 This Calculator

  1. Enter the property or loan price.
  2. Subtract any down payment.
  3. Set the interest rate.
  4. Choose the amortization period (payment calculation basis).
  5. Set the balloon term (when the lump sum is due).
  6. Optionally add extra monthly payments to reduce the balloon.
  7. Review the balloon amount and compare different terms.

Formula

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.

Frequently Asked Questions

What happens if I cannot pay the balloon?

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.

Why would someone choose a balloon loan?

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 (inheritance, bonus), or situations where long-term financing is unavailable. Use this as a practical reminder before finalizing the result.

How much of the loan is paid off before the balloon?

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.

Can I make extra payments to reduce the balloon?

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.

Is a balloon loan the same as an interest-only loan?

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.

What is a typical balloon loan term?

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.
