How it works
The calculator applies standard amortization math to estimate monthly principal and interest based on your loan amount, interest rate, and overall term. In a balloon structure, payments may be calculated over a longer amortization period, but the loan requires a remaining balance to be paid in full at a specific month before full amortization occurs. Federal Regulation Z addresses balloon-payment features in the context of ability-to-repay and qualified mortgage provisions, including specific rules for certain balloon-payment qualified mortgages.
Examples
Example scenario: A loan may be structured with payments calculated on a 30-year amortization schedule but with a balloon due after 7 years. During the initial years, payments reflect the longer amortization schedule. At the balloon date, the remaining unpaid principal becomes due in a lump sum. The calculator shows the scheduled payments, the outstanding balance at the balloon month, and total interest paid up to that point based on the inputs provided.
Limitations and important notes
Results are estimates of principal and interest only and rely on a simplified mathematical model. Actual loan contracts may include additional provisions affecting payment allocation, refinancing options, or maturity terms. This calculator does not determine eligibility, does not assess qualified mortgage status, and does not provide a rate quote. It does not include mortgage insurance premiums, funding fees, taxes, or closing costs.

FAQs
What is a balloon mortgage?
It is a mortgage that requires a larger lump-sum payment at a specified maturity date, rather than fully amortizing over the entire term. This calculator estimates principal and interest outcomes based on the structure you enter.
How is a balloon payment calculated?
The balloon amount is the remaining unpaid principal balance at the specified balloon month, based on the interest rate, payment schedule, and amortization assumptions used in the calculation.
Are balloon mortgages regulated under federal law?
Yes. Federal mortgage regulations under Regulation Z address balloon-payment features, including certain ability-to-repay and qualified mortgage provisions.
Does qualifying for a balloon mortgage depend on the lender?
Yes. Federal ability-to-repay standards require lenders to evaluate whether a borrower can meet loan obligations, and specific payment structures and approval decisions depend on lender underwriting within applicable regulations.
