Balloon Payment Calculator

Calculate payments for loans with a large final balloon payment

Balloon loans are common in commercial real estate and short-term business financing. They amortize over a longer period (say, 25 years) but the full remaining balance comes due at a shorter maturity (say, 5 years). This calculator shows your monthly payment, the balloon amount at maturity, and total interest paid.

  • Daily interest accrual — weekend payment dates shift to Monday with extra days counted
  • Full amortization table through the balloon date, with the balloon payment highlighted
  • Enter extra principal payments per row to see how prepaying reduces the balloon
  • Balance paydown chart with a balloon-due marker

Interest accrues daily (annual rate ÷ 365 × days in period). Weekend payment dates shift to Monday; extra days accrue interest. The balloon row shows the full remaining balance due at maturity. Extra principal payments reduce the balance and lower the balloon amount.

Frequently Asked Questions

What is a balloon payment?

A balloon payment is a large lump-sum payment due at the end of a loan term. The loan amortizes (calculates payments) as if it were a 25-year loan, but becomes due in full — the remaining principal balance — at year 5 or 7.

Are balloon loans common in commercial real estate?

Very common. Most commercial mortgages are 5-, 7-, or 10-year balloons amortized over 20–25 years. At maturity, borrowers typically refinance the remaining balance.

What's the risk of a balloon loan?

If rates have risen significantly at maturity, refinancing could be expensive. If the property value has declined, you may not qualify to refinance. Always have a plan for the balloon date.
