Auto Loan Calculator - Monthly Car Payment Estimator

Calculate your monthly car payment, total interest, and total loan cost. Compare different loan terms and down payments to find the best car financing option for your budget.

How Your Car Payment is Calculated

Your monthly car payment is determined by three main factors: the loan amount (price minus down payment), the interest rate (APR), and the loan term (number of months). Shorter terms mean higher monthly payments but lower total interest.

Smart Buying

Consider the total cost of ownership including insurance, maintenance, and fuel before committing to a loan.

The Mathematical Auto Loan Formula

M = P [ i(1 + i)ⁿ ] / [ (1 + i)ⁿ - 1 ]

M is the monthly payment. P is the principal loan amount. i is the monthly interest rate (annual rate divided by 12). n is the total number of months in the loan term.
