Every number below comes from the same small set of formulas, published on the methodology page, and the same vehicle data used throughout this site. Pick a tool below.
-
Rideshare profit
Turn a gross weekly fare number into an honest net: energy, wear, depreciation, insurance, and the car payment all come out first.
-
Cost per mile
Depreciation, fuel or electricity, insurance, maintenance, tires, and registration, combined into a single cents-per-mile figure and compared with the IRS standard mileage rate.
-
Break-even
Compare two cars — a cheaper one to buy against a cheaper one to run — and find the mileage where the pricier car catches up.
-
Payback period
How many weeks of driving it takes to earn back what a car cost to buy and put on the road.
All four calculators share the same tested cost library and the same fuel, electricity, and IRS-rate figures — see methodology for how each number is sourced and how the formulas are derived.
