Introduction

Plan before you borrow

A personal loan usually provides a fixed amount of money that is repaid in equal monthly installments. This calculator helps you compare offers by translating the loan amount, annual percentage rate, and repayment term into an estimated monthly obligation.

Use the result to evaluate affordability and compare scenarios. A longer term may lower the monthly payment while increasing total interest. A lower APR can reduce both the payment and total borrowing cost.

How it works

The formula behind the answer

The calculator converts the annual rate into a monthly rate and the term into a number of monthly payments. It then applies the standard amortizing-loan formula:

M = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1]

P is the principal, r is the monthly interest rate, and n is the number of monthly payments. Total interest equals all payments minus the original principal.

Example calculation

A $15,000 personal loan

  1. Enter a loan amount of $15,000.
  2. Use a 10.5% APR and a three-year term.
  3. Review the estimated monthly payment and full interest cost.
  4. Adjust the term or rate to compare alternatives.
