FanCulator: what a car costs and earns

FanCulator answers one question: would renting this car out be worth it?

What you tell it

Year, make and model, plus the city and state it would be rented in. Trim helps if you know it. Three more optional fields sharpen the answer: the car's value, its current mileage, and how much of it is paid off. If there is a loan, add the interest rate.

What it gives back

The top row shows the daily rate for your market, gross rental revenue per year, how many days a month the car would realistically be rented, and the payback period.

Underneath is the monthly breakdown: revenue, then depreciation (including the miles renters add), financing, insurance, maintenance, and other costs like cleaning, registration and storage. It ends at net profit per month and per year. Costs that do not apply, such as financing on a paid-off car, are left out.

The break-even view

The chart plots cumulative profit across five years. It starts below zero at the car's value and climbs as profit banks up. The line is grey until the car has paid for itself and green after. Hover any point to see how much is left until break-even, or how much has been made since. If the car never crosses zero in five years, the chart says so.
