About Balloon Loan Calculator
The Balloon Loan Calculator computes monthly payments based on a long amortization schedule (e.g. 30 years) and calculates the remaining lump-sum balloon payment due at loan maturity (e.g. 5 or 7 years).
Formula & Mathematical Calculation
Monthly Payment = Principal × [ r(1 + r)^n_amortization ] / [ (1 + r)^n_amortization - 1 ]
Balloon Balance Due = Principal × (1 + r)^n_balloon - Monthly Payment × [ ((1 + r)^n_balloon - 1) / r ]
Calculation Example
$250,000 Loan @ 7.0% (30-Year Amortization, 5-Year Balloon): Monthly Payment = $1,663.26/mo. Final Balloon Payment Due at Year 5 = $234,498.24.
