Road trip gas calculator

Enter where you're starting and where you're going, pick your car or type its mpg, and set how full the tank is. FuelWide plans the real driving route, works out how many miles you drive in each state, and prices the gas you burn in each one at that state's latest AAA average — then suggests where refuelling saves money. The US has no public station-price feed, so US suggestions are cheaper states, priced at state averages — not a specific cheapest station.

FuelWide plans the real driving route, splits it into the countries — and in the US, the states — it passes through, and prices the fuel used in each at that place's latest published average (European Commission, AAA, U.S. EIA, Statistics Canada and other registered sources). Verified vignette tariffs are added on top. Every figure in the result shows its source, date and confidence.

It compares two plans for the same trip: stopping wherever the tank runs low, and stopping at the cheapest places within your range — including individual forecourts with published prices near the route in Spain, France, Italy, Portugal, Slovenia and Bulgaria. The difference is the saving. If the difference is too small to be worth changing plans for (under about $3 or 3%), FuelWide says the route is already close to the cheapest option instead of inventing a saving.

Motorway vignettes are included for Austria, Hungary, the Czech Republic, Slovenia, Switzerland and Bulgaria. Selected Greek toll plazas on the A1, A2 and A25 are also included when the route crosses them, using official passenger-car tariffs. Each crossing is itemised, including the return journey. Greek coverage is partial: other plazas, ramps and bridges may add charges. Tolls in France, Italy and on US turnpikes remain unavailable, and incomplete totals are marked as the known cost.

Yes. Electric trips use the same engine with consumption in kWh/100 km, a charging plan that stops at around 80%, and residential electricity estimates where we hold them. Public and rapid charging usually cost more; FuelWide doesn't have charger tariffs yet and says so on every EV result.

They are the latest published averages and forecourt reports, not live pump prices. Station prices come from national price-reporting feeds; national and state figures are averages. Your actual cost depends on the stations you choose, traffic and driving style.
