⛽ Fuel Cost Calculator
Estimate trip fuel cost from distance, mileage and fuel price.
About this tool
Estimates how much a trip will cost in fuel, based on the distance, your vehicle's fuel efficiency, and the current price of fuel — handy for budgeting a road trip or comparing commute costs.
Splitting a road trip's fuel cost with passengers afterward? The Split Bill Calculator can divide that total evenly.
Worked example
A 400-mile road trip in a car that gets 28 mpg, with gas at $3.60 a gallon, costs roughly $51.43 in fuel.
How to use it
- Enter the trip distance.
- Enter your vehicle's mileage (miles or km per unit of fuel).
- Enter the fuel price per unit and press Calculate.
Tips
- Use your car's actual average mileage rather than the manufacturer's rated figure for a more realistic estimate.
- Fuel prices fluctuate — check a current local price for accuracy rather than an old receipt.
- For a round trip, double the distance before calculating, or calculate one way and double the result.
FAQ
Does this account for traffic or driving style?
No — it's a straight calculation based on the mileage figure you enter, which already reflects real-world driving if you use your actual average.
Can I use this for electric vehicles?
Not directly, since it's built around fuel volume and price rather than kWh — though you could approximate by treating kWh as the "fuel" unit.
What if I don't know my exact mileage?
Check your vehicle's manual or trip computer for an average MPG or L/100km figure.
