Fuel Calculator: Carculate

Gas Mileage & Cost Calculator helps you calculate gas costs in seconds—and now lets you choose from an offline database of more than 100,000 vehicles instead of entering every value yourself.

New: Offline Vehicle Database

Browse over 100,000 vehicle configurations covering 238 makes and more than 6,700 models. Search by make, model and year, then save your car to preload its mileage and fuel data in the calculators.

- Search and filter cars offline
- Filter by data source, powertrain and gas mileage
- View combined, city and highway figures when provided by the source
- See engine, transmission, drivetrain and CO₂ details when available
- Save vehicles for quick calculations and side-by-side comparisons

The catalog combines public vehicle data from government and public-sector agencies across North America, Europe and Asia. Each vehicle shows its source and test standard when available.

Four Useful Calculators

- Trip Cost: Estimate the gas cost of any drive
- Distance: Calculate how far you can travel with the gas you have
- Gas Mileage: Calculate fuel economy from distance and fuel used
- Fuel Needed: Find how much gas you need for a trip

Compare Cars

Compare trip costs and fuel use across saved vehicles. Clear lowest- and highest-cost indicators make it easy to choose the most economical car for a drive.

Flexible Units and Settings

Use miles, kilometers or meters; US gallons, UK gallons or liters; MPG, L/100 km, km/L and other consumption units; plus multiple currencies. Set preferred units for each vehicle and choose light, dark or dynamic color themes.

The vehicle database and calculators work offline. The free version contains ads and supports up to two saved vehicles. A one-time Premium purchase removes ads and unlocks unlimited vehicle profiles.
