Results are estimates and depend on real fuel consumption, driving style, and road conditions.
Frequently Asked Questions (FAQ)
Enter the distance, your car's fuel consumption (in L/100km, km/L, or mpg), and the fuel price. The calculator computes one-way cost, round-trip cost, cost per km, and monthly/yearly budget.
We support three formats: L/100km (standard in Bulgaria and the EU), km/L, and mpg (US gallon). The tool automatically converts the value into the internal L/100km standard for the calculation.
Mpg (miles per gallon) is a consumption measure used mainly in the US. The calculator converts mpg into L/100km using the standard US gallon formula, so you can compare values from different sources.
Yes. Check the "Include toll/vignette fee" option and enter the amount per direction — it is automatically doubled when calculating the round-trip cost.
Enable the "Compare with a second car" option, enter the data for both vehicles, and the calculator will show which car is cheaper for this trip, plus the monthly and yearly difference.
Currently the tool is optimized for petrol, diesel, and LPG. Support for electric vehicles (kWh-based calculation) is planned for a future version.
The calculator supports EUR, USD, and TRY. Choose the currency you buy fuel in — the tool does not perform currency conversion, it simply displays the result in the selected currency.
Note the odometer reading at a full tank, drive as usual, then refill to full again. Divide the distance travelled by the liters used and multiply by 100 — that's your real consumption in L/100km.
Just type the city names into the "Point A" and "Point B" fields — as you type, suggestions from a mapping service will appear. Pick the cities from the list and the real driving distance will fill in the distance field automatically.
Yes. Use the "+ Add waypoint" button to add up to 3 extra stops between the start and end point. The calculator computes the total distance for the whole route in the correct travel order.
Yes, the feature works for cities anywhere in the world, not only in Bulgaria — you can search for any location.
No. Recently searched routes are stored only in your browser (localStorage) for quick reuse — they are never sent to or stored on our server. You can clear them anytime with the "Clear history" button.
Results are estimates and depend on your car's real consumption, driving style, load, and road conditions. We recommend entering your real average consumption rather than the manufacturer's stated figure.
No. The tool is completely free and requires no account or registration — just enter your details and get an instant result.
Enter the number of travellers in the "Number of travellers" field — the calculator automatically splits the round-trip cost equally among everyone.
