Route Fuel Cost Planner
Estimate the true fuel cost of a trip, how many fill-ups you'll need, and when it's worth detouring for cheaper fuel.
Beta data note: Station locations are map-based (OpenStreetMap). Prices are regional estimates unless a live price source is shown — we do not display per-station prices we can't verify.
Enter a US ZIP (e.g. 43555) or Canadian postal code (e.g. K1A 0B1).

- Are the station prices live?
- No. FuelHere shows real station locations from OpenStreetMap, but pump-level prices aren't connected to a live feed yet. We show your regional EIA average at the top as honest context — individual station prices may be higher or lower.
- How does FuelHere estimate detour savings?
- We measure approximate out-and-back distance from your route to each station. Combined with your MPG and tank size, that gives a break-even table: how many cents per gallon cheaper a station must be to make a given detour pay off.
- How far should I detour for cheaper fuel?
- It depends on your MPG, tank size, and how much cheaper the alternative is. At 25 mpg, a 5-mile out-and-back burns ~0.4 gallons — so for a 15-gallon fill you need savings of ~10¢/gal just to break even. Use the break-even table to set a sensible max detour.
Editorial disclaimer: these are estimates, not financial advice. Real-world costs vary with traffic, terrain, weather, driving style, regional taxes, and fuel-card terms. Need the simpler weekly view? Try the Fuel Cost Calculator.
