What is the Loan Calculator?

The Loan Calculator works out the fixed monthly payment for any personal loan from its amount, annual interest rate, and term in months. It also shows the total amount you'll pay over the life of the loan, total interest, and the projected payoff date, using the standard fixed-rate amortization formula lenders use.

How to Use It

Enter the loan amount, the annual interest rate the lender quoted you, and the term in months, then press Calculate. The result shows your monthly payment, total payment, total interest, and the month and year the loan would be paid off if you make every payment on schedule.

When to Use It

Use it before signing for a personal, auto, or other installment loan to confirm the payment fits your budget, when comparing offers from different lenders with different rates or terms, or when deciding whether a shorter term's higher payment is worth the interest savings.

Who Benefits

Anyone shopping for a personal loan, car loan, or other fixed-term financing can use it to compare real numbers across lenders rather than relying on advertised rates alone. Tips to reduce total cost: shop multiple lenders for the best APR, make extra principal payments when possible, choose the shortest term you can afford, and improve your credit score before applying.

Frequently Asked Questions

Monthly payment = P × [r(1+r)^n] / [(1+r)^n − 1], where P is the principal, r is the monthly interest rate (annual rate ÷ 12), and n is the number of monthly payments. This is the standard amortizing loan formula used by all lenders.
The interest rate is the annual cost of borrowing the principal. APR (Annual Percentage Rate) includes the interest rate plus fees and other loan costs. APR gives a more accurate picture of the true cost of a loan and is the number to compare across lenders.
A secured loan is backed by collateral (like a car or home). If you default, the lender can seize the asset. Unsecured loans (like personal loans) have no collateral, so lenders charge higher rates to offset the risk.
