About Wheelwise

Why it exists

The monthly payment is only a slice of what a car costs. Depreciation, interest, fuel, insurance and upkeep add up to a much bigger number. We made this calculator to show the full cost per month and per mile before you buy.

Wheelwise is a free, independent web tool. The real monthly and per-mile cost of owning a car.

We build small, fast tools that run entirely in your browser: no sign-up, no data uploads. The site is funded by advertising and an optional ad-free premium plan.

Who writes the guides

Guides are written by the Wheelwise editorial team, a small independent publisher. We write them in plain language, test every example with the calculator, and link to official sources (such as the IRS, the SEC or the marketplace's own fee pages) so you can verify the rules yourself.

We do not accept paid placements, and we do not recommend specific financial products. If you spot an error, write to us at contact@moneycalcdesk.com and we will correct it and update the date.

Accuracy

We work hard to keep formulas and reference data up to date, and every guide shows when it was last updated. Results are estimates; always double-check important decisions with a qualified professional.
