Balloon Loan Final Payment Calculator

balloon = P · (1 + r)^n − M · [((1 + r)^n − 1) / r].

Compute the final balloon payment on a partially-amortising loan. The borrower pays a smaller fixed monthly payment M (insufficient to fully amortize) for n months, then a single balloon payment at month n+1 covers the remaining balance: balloon = P · (1 + r)^n − M · [((1 + r)^n − 1) / r] (r = monthly rate).
