Fuel Price and Fleet Cost Calculator
Enter either miles and MPG, or measured gallons per vehicle. Add idle/generator fuel only if it is excluded from your driving or measured-gallons figure. One consistent reporting period.
Use a decimal point and optional comma thousands: 1,234.56. Enter zero explicitly where appropriate. Prices and costs must share the same scope and currency. Examples are illustrative, not live prices.
Nothing saves automatically. Keep downloaded files private. Restoring a project does not refresh its price assumptions.

Fuel, fleet & generator cost
Enter either miles and MPG, or measured gallons per vehicle. Add idle/generator fuel only if it is excluded from your driving or measured-gallons figure. One consistent reporting period.
Formula: Gallons = vehicle count × (miles/MPG OR measured gallons + separately counted idle/generator hours × burn); fuel cost = gallons × USD/gallon.
Example uses illustrative prices only. Select Load illustrative example to inspect every input. Values can be zero or negative in results where costs exceed proceeds.

Provider prices are references, not execution promises. Dealer terms, purity, quantities, condition, collectible premium, shipping, taxes and market availability require your matching evidence. No automatic risk probabilities, future price forecasts or investment recommendations are generated. Downloaded receipts are editable and unsigned; they preserve calculation assumptions, not proof of authenticity or a completed trade.
These free workspaces support ordinary browser printing and JSON calculation receipts. They are not new paid products, and their full multi-table studies are not automatically included in the existing paid report packs.
