Balloon Payment Calculator

A balloon payment calculatoris a financial tool that calculates the payments and costs associated with balloon loans - loans where you make regular payments for a set term followed by one large "balloon" final payment. Unlike fully amortizing loans that pay off the entire principal over the term, balloon loans leave a significant portion of the principal due at the end. The balloon payment calculator takes the loan amount, APR, term, balloon amount (or percentage), and payment frequency, then computes the regular payment amount, the balloon payment due at maturity, total interest paid, total cost, loan-to-value ratio at balloon, and a refinance risk assessment - all with a full amortization schedule. Everything runs entirely in your browser with no data uploaded to any server.

1. Enter Your Loan Details: Input the total loan amount, annual percentage rate (APR), and the loan term in months or years. Select the payment frequency - monthly, bi-weekly, or weekly - to match your actual payment schedule.
2. Configure Balloon Payment Terms: Specify how the balloon payment is determined. You can either enter the balloon amount as a dollar value (e.g. $50,000 due at end) or as a percentage of the original loan amount (e.g. 30% balloon = 30% of principal due at maturity). The calculator also supports an interest-only period option for loans that start with interest-only payments.
3. Review the Complete Analysis: The calculator displays the regular payment amount, the balloon payment due at maturity, total interest paid over the life of the loan, total cost (principal + all interest + balloon), loan-to-value ratio at balloon maturity, and a refinance risk assessment. View the full amortization schedule showing payment-by-payment breakdown of principal, interest, and remaining balance leading up to the balloon payment.

• Regular Payment Amount: The amount due each payment period (monthly, bi-weekly, or weekly) throughout the loan term before the balloon payment comes due. This is calculated using the standard amortization formula adjusted for the balloon balance remaining at the end.
• Balloon Payment at Maturity: The large lump-sum payment due at the end of the loan term. This represents the remaining principal balance that was not amortized over the regular payment period. The balloon payment can be specified as a fixed dollar amount or as a percentage of the original loan amount.
• Total Interest & Total Cost: The total interest paid over the life of the loan (excluding the balloon payment principal) and the total cost including all regular payments plus the balloon payment. This gives you the true cost of the balloon loan structure compared to a fully amortizing loan.
• LTV Ratio & Refinance Risk Assessment: The loan-to-value ratio at the balloon maturity date, calculated as the balloon payment relative to the original collateral value. The refinance risk assessment provides a qualitative evaluation of how likely refinancing will be available based on the LTV ratio, current rate environment assumptions, and loan structure.

The balloon payment calculator is 100% free with no signup required. All calculations are performed locally in your browser - your loan amounts, interest rates, and financial details never leave your device. There are no usage limits or restrictions. The tool supports multiple payment frequencies (monthly, bi-weekly, weekly), custom balloon amounts or percentages, interest-only periods, and generates a complete amortization schedule you can review payment by payment. Use it as many times as you need to structure balloon loans, compare financing options, or plan refinance strategies.
