Fuel Cost Calculator — Trip Fuel & Petrol Cost Estimator
Calculate the fuel cost for any road trip by entering your distance, fuel efficiency, and local fuel price. Supports km and miles for distance; L/100km, km/L, US MPG, and UK MPG for efficiency; and litres, US gallons, or UK gallons for fuel pricing. Plan for multiple vehicles or calculate the per-person cost when splitting among passengers. Average fuel efficiencies for reference: city car ~6–8 L/100km (35–47 MPG US), family SUV ~10–14 L/100km (17–24 MPG US), electric vehicle equivalent ~1.5–2.5 L/100km.
