The real cost of a car lives beyond the sticker — the payment you can carry, the lease behind the monthly quote, the fuel, and everything you'll spend keeping it running. Run a few of these side by side and the smart buy tends to stand out.
Start from a monthly budget, APR, term, down payment, and trade-in to find the car price you can actually afford.
Add up a year of fuel, insurance, maintenance, and other costs, divide by miles driven, and see what each mile costs.
Estimate a monthly lease payment from price, residual, money factor, term, and down, split into depreciation and finance.
Compare two cars by MPG over a year of driving at a set fuel price to see the annual gas savings between them.
Multiply tank size by MPG for your range on a full tank, plus what it costs to fill up at today's fuel price.
Fold in purchase price, fuel, insurance, maintenance, and resale value for the true total and annual cost of a car.
Frequently asked questions
Which auto calculator should I start with?
Depends on where you are. Still shopping? The Car Affordability Calculator sets your ceiling. Torn between two cars? Run each through the Cost of Ownership Calculator. Comparing a lease to a loan? The Lease Payment Calculator lines it up against a monthly loan payment.
Are these numbers exact?
They're solid estimates, not final quotes. Real deals carry taxes, dealer fees, and rate details that shift the figures a little. Use these to compare options and walk in informed, then confirm the specifics on the paperwork.
Do the fuel tools use my real driving?
They use whatever you enter, so the closer your MPG and mileage are to reality, the better. Window-sticker MPG is a lab average; if your city commute drags it down, plug in the number you actually get for an honest result.
Why does cost of ownership beat the monthly payment?
The payment ignores depreciation, fuel, insurance, and upkeep, which together often cost more than the loan itself. A cheaper monthly can hide a pricier car to own, and the Cost of Ownership Calculator is where that shows up.
