About the Loan Calculator

This calculator finds the fixed monthly payment required to fully pay off a loan, along with the total interest paid over its life, using the standard installment loan formula.

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 number of monthly payments.

This applies to personal loans, auto loans, student loans and any other fixed-rate, fixed-term installment loan.
