- Using an outdated fuel price.
- Forgetting this is a one-way estimate — double it for round trips.
How fuel cost is calculated
The math behind the estimate
Liters needed = Distance ÷ Mileage. Total cost = Liters needed × Fuel price per liter. For example, a 250km trip at 15km/l needs 16.67 liters.

Accuracy & limitations
This calculator is built for speed and accuracy, but it's worth understanding what it does and doesn't account for:
- Assumes constant mileage. Real-world mileage varies with traffic, terrain, load, and driving style.
- Manual fuel price. This tool doesn’t fetch live fuel prices — enter the current local price yourself.
- One-way estimate. Enter the round-trip distance directly if you're planning a return journey.

Yes, just enter the total round-trip distance instead of the one-way distance.
Convert to km per liter first (divide km/gallon by ~3.785) before entering.
No. All calculations run entirely in your browser, and nothing you enter is ever sent to a server or stored.
