Free used-car buying calculators

Work through the numbers before you make an offer. These calculators use your inputs, explain their assumptions, and give results without an account or payment.

• Used-Car Out-the-Door Price Calculator

  Estimate a used car’s purchase total from your selling price, tax assumptions and fees. Keep the down payment separate and see what remains unknown.

• Used-Car Offer Calculator

  Plan an opening-offer range and ceiling from your own fair-value estimate and repair allowance. See the complete formula without inventing a market valuation.

• Used-Car Mileage by Age Calculator

  Calculate approximate vehicle age and miles per year from model year and mileage. Understand the calendar-year assumption without treating mileage as a reliability score.
