Free calculators · no account, nothing saved
Run the numbers before they do.
The same math the finance office uses: out-the-door price, loan cost, lease payments, trade equity, the true monthly cost of owning a car, and rebate versus 0% APR. Free, in your browser, and nothing you type is sent anywhere.
The calculators
Out-the-door price
Turn a selling price into the number you actually pay: fees, add-ons, tax, title, trade and payoff.
Car loan cost
Payment, total interest and total paid for two loan offers side by side, plus what a dealer rate markup costs.
Lease checker
Check a lease quote line by line: depreciation, rent charge, tax, and the APR hiding in the money factor.
Trade equity
Are you ahead or upside-down on your trade, and what does that do to your next loan?
True monthly cost
Payment is only part of it. Add insurance, fuel or charging, and maintenance to see the real monthly and per-mile cost.
Rebate vs 0% APR
The factory offers cash back or a promo rate, usually not both. See which one costs less in total.
