What is the car loan calculator?

In short

A $25,000 car loan at 7.5% APR over 60 months costs $501/month with $5,042 in total interest. Extending to 72 months lowers payments to $432 but adds $2,100 extra in interest.

This car loan calculator finds your monthly payment, total interest, total paid, and the true cost of the vehicle. It also shows a full amortization schedule and a donut chart of principal vs interest.

How to use this calculator

  1. 1Enter the car price, down payment, and trade-in value.
  2. 2Select the loan term (24–72 months).
  3. 3Enter the annual interest rate (APR).
  4. 4Read the monthly payment and total interest cost.

The formula

M=P×r(1+r)n(1+r)n−1
Monthly payment = loan × r(1+r)^n / ((1+r)^n − 1), where r = monthly rate (APR ÷ 12) and n = term in months.
M
— Monthly payment
P
— Loan amount (price − down payment − trade-in)
r
— Monthly interest rate (APR ÷ 12)
n
— Number of monthly payments

Worked example

The scenario

$28,000 car, $3,000 down, 60-month term, 7.5% APR, no trade-in.

gives

The result

Loan = $25,000. Monthly payment ≈ $501. Total paid ≈ $30,041. Total interest ≈ $5,041. True car cost ≈ $33,041 (price + interest).

Common use cases

  • Comparing different loan terms on monthly payment and total cost
  • Deciding how much to put down to reduce interest
  • Evaluating the true cost of a car after financing
  • Understanding how dealer rate offers compare to credit union rates

Limitations & assumptions

  • Does not model dealer fees, registration, or sales tax.
  • Assumes a fixed interest rate for the entire term.
  • Does not model GAP insurance or extended warranty financing.
  • Does not account for the car's depreciation — the true economic cost also includes value lost over time.
