HOW IT WORKS

Four steps. No car-buying jargon required.

You can start with only the numbers on your quote. When a number is unfamiliar, tap the ? next to it for a plain-English explanation and where to find it.

01

Enter the deal

Price, total price, state and any fees you know.

02

Add financing

Trade-in, down payment, APR and loan term — when available.

03

Add ownership

Fuel, insurance, maintenance and mileage. Estimates are clearly labeled.

04

Get your checklist

See the important numbers, warnings and questions to ask.

WHY THIS EXISTS

Most car calculators stop at the payment.

A payment is only one part of the decision. A low monthly payment can come from a longer loan, while a trade can hide negative equity and dealer add-ons can change the amount you actually pay.

TrueCarCost starts with the deal and walks through the rest. The result is not a black-box “AI score.” Each warning is tied to a number you can verify on the quote or loan paperwork.

Built for two moments

  • At the dealership: use the deal analyzer while you review a written offer.
  • Before shopping: use the comparison tool to understand which option fits your budget and ownership plans.

Important: This is a planning tool. Tax rates, dealer fees, financing offers, insurance and vehicle values vary. Verify the final contract and actual quotes before signing.
