## About

### Estimate the fuel cost of any trip

Enter the distance, your vehicle's fuel economy, and the current fuel price, and get the total cost for the journey — one way or round trip. It's the quick check before a road trip, a commute comparison, or splitting fuel fairly between passengers.

### Compare routes, cars, and carpooling

Change the economy figure to compare two vehicles, or the distance to weigh a shorter toll route against a longer free one. The maths is distance ÷ economy × price, but running it for real trips — and dividing by the number of people sharing — is where the calculator saves you the effort.

## FAQ

### How do I calculate the fuel cost of a trip?

Divide the trip distance by your vehicle's fuel economy to get the fuel used, then multiply by the fuel price. For example, 300 miles ÷ 30 MPG = 10 gallons; at $3.50/gallon that's $35. This tool handles MPG, km/L, and L/100km automatically.

### What's the difference between MPG, km/L, and L/100km?

MPG (miles per gallon) and km/L (kilometers per litre) measure distance per unit of fuel — higher is better. L/100km measures fuel per 100 km — lower is better. Pick the one on your dashboard and enter distance in the matching unit.

### Can I split the cost between passengers?

Yes. Enter the number of people and the calculator divides the total fuel cost evenly, so everyone knows their share for a carpool or road trip.

### Is my trip data saved?

No. All calculations happen locally in your browser and nothing is uploaded or stored.
