How the Auto Loan Calculator Works

Auto loans use the same standard amortization formula as other fixed-rate loans: M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1 ]

Where P is calculated as: Vehicle Price − Down Payment − Trade-in Value (if applicable).

  2. Enter your down payment and/or trade-in value
  3. Select your loan term (typically 36-72 months)
  4. Enter your interest rate
  5. Click Calculate to see your monthly payment and total loan cost

Frequently Asked Questions

How much should I put down on a car?

A common recommendation is 10-20% down for a new car, and 20% or more for a used car, though this varies based on your budget and loan terms.

Does my credit score affect my auto loan rate?

Yes, significantly. Higher credit scores typically qualify for lower interest rates, which can save substantial money over the life of the loan.

Should I choose a longer loan term for a lower payment?

Longer terms reduce monthly payments but increase total interest paid and can lead to being "upside down" on the loan for longer.

Does this calculator include taxes and fees?

This calculator estimates payment based on the loan principal you enter. Sales tax, registration, and dealer fees should be added to your vehicle price if financed.
