Balloon Loan Calculator — Monthly Payment and Final Balloon
I’m Selina Marquez, Finance Consultant & Investment Specialist. Use this balloon loan calculator to estimate two outcomes: the fixed monthly payment based on a full-term amortization and the remaining balance due as the balloon at your chosen earlier payoff point.
Quick Start
Enter loan amount in $.
Enter annual interest rate in % (APR, no fees).
Enter total loan term in years.
Enter balloon term in years (when the large final payment is due).
Press Calculate. You’ll see monthly payment and balloon balance.
How It Works
The tool treats your monthly payment as if the loan fully amortizes over the total term. However, you stop earlier and pay a balloon equal to the remaining principal at the end of the balloon term. Interest compounds monthly. Payments are monthly, level, and on-time. No fees or taxes included.
Inputs → Outputs
Inputs (units): Loan Amount ($), Annual Interest Rate (%), Loan Term (years), Balloon Term (years).
Validation: All values must be positive; balloon term must be ≤ loan term; rate > 0 in standard case.
Outputs: Monthly Payment ($/month), Balloon Payment ($ at balloon date).
Formula / Method
Assumptions: monthly compounding; level monthly payments; no fees; no prepayment penalties.
Scenario: $25,000 loan; 6.50% annual rate; 5-year term; balloon at year 3.
monthly_rate = 6.50 / 12 / 100 = 0.0054166667
n_payments = 3 × 12 = 36
monthly_payment = $488.13
balloon_balance at month 36 = $14,217.37
Result: You’d pay about $488.13 per month, then a final balloon of $14,217.37 at month 36.
Applications / Use Cases
Auto or equipment loans structured with lower interim payments and a large final payoff.
Bridge financing where a refinance or asset sale is expected before full amortization.
Investor scenarios managing cash flows while anticipating future liquidity.
Tips / Common Mistakes
Balloon term must be ≤ loan term. Otherwise the balloon isn’t reached.
Rate is APR for interest only; fees and taxes increase real cost but aren’t modeled.
Higher rates raise both monthly payment and balloon balance materially.
If you extend the total term (keeping balloon date fixed), monthly payment falls but the balloon rises slightly.
Insight / Trade-offs
Balloon structures improve near-term cash flow but concentrate principal risk at maturity. Ensure realistic refinancing or sale plans. ESG-minded operators should assess the financial resilience of projects under rate shocks before adopting balloon debt structures.

Frequently Asked Questions
What is a balloon payment?
A balloon payment is a large final payoff due at a set date after making smaller regular payments that don’t fully amortize the loan by that date.
How does this calculator compute the monthly payment?
It uses a standard amortization payment over the full term, then calculates the remaining balance at the balloon term using monthly compounding.
Can the balloon term be longer than the loan term?
No. The balloon term must be less than or equal to the total loan term to be valid.
Does the calculator include fees or taxes?
No. It models interest and principal only. Origination fees, taxes, and insurance are excluded.
What if my interest rate is 0%?
At 0%, the monthly payment equals loan_amount divided by total months, and the balloon equals the unpaid principal at the balloon date.
How sensitive is the balloon to the interest rate?
Highly. Higher rates slow principal reduction, increasing the remaining balance due at the balloon date.
Is a balloon loan right for me?
It suits borrowers needing lower interim payments with a credible plan to refinance or pay off the balloon at maturity; assess risks and liquidity carefully.
