Punch in what you want to borrow, the yearly rate a lender is offering, and the number of years to pay it back; the monthly payment, lifetime total, and interest cost refresh as you type.
Inputs are clamped so a blank or negative amount, rate, or term cannot produce a divide-by-zero or negative result.
Select "Show first 12 months" to see a month-by-month breakdown of principal and interest, capped at 12 rows even when the term itself is longer.
Loan Calculator
Work with a personal, auto, or student loan: give the amount you are borrowing, the yearly interest rate, and how long you will repay, and the monthly payment appears at once.
Change the loan amount, rate, or term at any time - the monthly payment, total paid, and total interest recalculate immediately, with no submit button to click.
Key features
- Enter the loan amount, annual interest rate, and term in years; the monthly payment, total paid, and total interest update as you type.
- The math runs locally using the standard amortization formula - no upload and no account.
- An optional 12-month amortization table breaks down how each monthly payment splits between principal and interest, even when the loan term itself runs longer than a year.
When to use it
Line up two lenders side by side - nudge the amount or rate and watch the monthly payment and total interest move, so you can tell a cheaper offer from a costlier one before you sign.
