Loan Payment Formulas & How to Figure a Loan

Understanding how do you figure out a loan payment with interest and how do you work out loan repayments helps you compare offers from any lender.

Standard Loan Payment Formula

M = P × [r(1+r)n] ÷ [(1+r)n−1]

Where: P = principal, r = periodic rate, n = total payments. This is how our credit calculator and loan calculator balance solver works.

Extra Payments Strategy

With our additional payment loan calculator, each extra dollar paid goes directly to principal reduction, cutting interest that compounds on the remaining balance. Even $50–$100 extra monthly can save thousands.

Balloon Mortgage Risks

The amortization schedule for mortgage with balloon payment calculates payments as if fully amortizing, but requires a large lump-sum at the end. Our amortization schedule for balloon mortgage tool shows the exact balance due on that date.
