Payback period calculator

What this calculates

Payback period is the number of weeks of driving needed for net earnings to add up to what the car cost to acquire. This calculator adds purchase price to upfront costs — things like initial registration, an insurance deposit, or a pre-trip detailing job that only happen once — and divides that total by net earnings per week. Net earnings, not gross, is the number that matters here: it should already have energy, wear, depreciation, insurance, and the car payment subtracted, which is exactly what the rideshare profit calculator produces. Feeding gross weekly fares into this tool instead of net earnings will produce a payback period that looks far shorter than reality, since it ignores everything the car costs to keep running.

Assumptions baked in

Net weekly earnings are assumed constant for the whole payback period, which is rarely exactly true — driving hours, seasonal demand, and platform pay rates all move around — so this number is best read as an estimate under current conditions rather than a guarantee. If net weekly earnings are zero or negative, the car never pays for itself under those conditions and the calculator says "Never" rather than dividing by zero or a negative number and returning a nonsense result; in that case, the fix is to check the cost-per-mile breakdown before committing to a purchase, since a car that costs more per mile than it earns will never reach payback no matter how many weeks pass. The calculator does not account for financing interest paid over time, opportunity cost of the money spent, or a car needing an unplanned repair mid-payback, all of which extend the real-world period beyond this estimate. It is a floor on how long payback takes, not a ceiling.
