Balloon Loan Calculator
Balloon loans offer low monthly payments based on a long amortization schedule (often 30 years), but the remaining principal comes due as a single large 'balloon' payment at the end of a much shorter term (often 5 to 7 years). They are common in commercial real estate and some auto and mortgage products, and they appeal because the low payments improve cash flow in the near term. This calculator shows the monthly payment, the balloon amount due at the end of the term, and the total interest paid over the term, so you can see both the affordable near-term payment and the large obligation waiting at the end. Enter the loan amount, the interest rate, the loan term (years until the balloon), and the amortization period the payment is based on, and the calculator returns the monthly payment, the balloon balance due, and the total interest. The central risk of a balloon loan is that you owe a large lump sum at once; if you can't refinance or sell the asset by the balloon date, you may default, so you need a clear exit strategy before signing. Refinancing is often possible if you qualify and rates are favorable, but it's not guaranteed — if rates rise, your income drops, or the asset's value falls, you may be unable to refinance and forced to sell or face default. The monthly payment is calculated using the longer amortization period, which is what keeps it low; the balloon is simply the remaining principal after the shorter actual term. Use this calculator to understand the full structure of a balloon loan before committing, to plan a refinance or sale well before the balloon date, and to stress-test what happens if rates or your circumstances change before the balloon comes due.

Frequently Asked Questions
What is a balloon payment?
A large lump-sum principal payment due at the end of a balloon loan's term, after a period of smaller amortized payments.
Why are balloon payments risky?
You owe a large sum at once. If you can't refinance or sell, you may default. Plan an exit strategy before signing.
How is the monthly payment calculated?
It is based on the longer amortization period (e.g., 30 years), which keeps it low. The balloon is the remaining principal after the shorter term.
Can I refinance a balloon loan?
Often yes, if you qualify and rates are favorable. But refinancing is not guaranteed — especially if rates rise or your finances change.
Where are balloon loans common?
Commercial real estate, some jumbo mortgages, and certain auto and equipment loans. They are less common in standard residential mortgages.
