Frequently Asked Questions

We combine three things: fuel (or EV electricity) consumption based on your vehicle and distance, tolls computed per country from the kilometres you drive in each one, and vignettes for countries that require them. You can override the fuel price, consumption, and currency at any time — your inputs always take priority over our defaults.

We currently cover 30+ European countries plus selected routes outside Europe. Toll and vignette pricing is included for every country where it applies — France, Italy, Spain, Portugal, Croatia, Greece, Poland, Hungary, Austria, Switzerland, Czechia, Slovakia, Slovenia, Romania, Bulgaria, Moldova, North Macedonia, and more.

Yes, it is free, with no sign-up required. The core calculator will never be put behind a paywall. The site is funded by affiliate links and (optional, consent-based) display advertising, which is what allows us to keep the core tool free for everyone.

Yes. Trip Cost Calculator is a Progressive Web App (PWA). Install it from your browser ("Add to home screen" on mobile, install icon in the address bar on desktop) and previously-loaded routes work without an internet connection. New route calculations require connectivity for the directions API.

We seed the calculator with reasonable per-country averages for petrol, diesel, and electricity, refreshed periodically. Because prices vary by station and by day, the real value of the calculator is that you can override the price in two clicks — type the actual €/L (or $/gal, or €/kWh) you expect to pay and the whole trip recalculates instantly.

Toll rates are sourced from official operator websites (ASFA in France, AISCAT in Italy, ANAS, ASFINAG in Austria, and others) and reviewed periodically. Vignette prices come from each country's official issuer (ASFINAG, DARS, NM, etc.). We treat them as estimates because operators occasionally adjust mid-year and exchange rates fluctuate. For a high-stakes trip, always cross-check at the booth or the issuer's website.

Email us at [email protected] with the country, the route, and a link to the official price source if you have one. Pricing corrections usually ship within a week. Feature requests and bug reports go to the same address.

Yes. Switch the vehicle type to electric and the consumption units (kWh/100km or mi/kWh), default per-country electricity prices, and charging cost calculation all adapt automatically. You can override the consumption and the price per kWh just like you can for petrol or diesel.

The fastest route is Google Maps' default — usually motorways with tolls. The cheapest route avoids tolls and vignettes where possible, even if it adds time. We show both side-by-side with full breakdowns (time, distance, fuel cost, fuel volume, tolls, vignettes) so you can pick the trade-off that matches your priorities.

Cost depends on the price you input, but volume depends only on your vehicle's consumption and the trip distance. Showing both lets you sanity-check the estimate against your own experience ("that sounds about right for a tank-and-a-half") and re-price the trip on the fly if fuel prices change.

Yes. The calculator supports 30+ currencies and both metric (km, L) and imperial (mi, gal) units. Pick your preference once and every value on the page converts at consistent reference rates. Your choice is saved in your browser for next time.

We translate the interface into 30+ languages including English, German, French, Spanish, Italian, Portuguese, Polish, Dutch, Czech, Hungarian, Romanian, Greek, Russian, Ukrainian, Turkish, Arabic, Hebrew, Persian, Hindi, Bengali, Chinese, Japanese, Korean, and more. Right-to-left languages are fully supported.

No. There are no accounts, no email collection, and no server-side history. Your trips, preferences, and inputs are stored only in your browser's localStorage. We use Google Analytics and Microsoft Clarity for anonymised traffic analytics, and only after you accept the analytics cookie category in the consent banner. Full detail is in our Privacy Policy.

Yes, transparently. We use affiliate links for hotels (Trip.com / Booking partners) and for online vignette resellers in countries that allow it. If you book through one of these links, we earn a small commission at no extra cost to you. Affiliate CTAs are labelled and disclosed in our Privacy Policy.
