What is Loan Calculator?

Loan Calculator computes monthly payments, total interest, and provides an amortization summary for any fixed-rate loan based on principal, interest rate, and term.

When to use this tool

How it works

Uses the amortization formula: M = P × [r(1+r)^n] / [(1+r)^n - 1], where P is the loan amount, r is the monthly interest rate, and n is the total number of months. Generates a full amortization schedule showing principal vs interest split per payment.
