Fuel & Trip Cost Calculator: Tolls, Parking, EV & MPG

About Fuel & Trip Cost Calculator

Compare the cost of driving before you set off. Estimate multi-leg fuel or EV charging costs with explicit US and UK units, tolls, parking, passenger splitting and monthly trip counts. All prices are entered by you. The core workflow is designed to run in your current browser.

Compare driving costs without mixing gallons or charging loss

Add one-way legs and mark return legs; their tolls double while parking stays once per trip.
Match fuel vehicles to L/100km, km/L, US/UK MPG and the correct price unit; match EVs to electricity units.
Generate per-leg and period totals, inspect rounded shares and export assumptions.

US and UK MPG differ

At 30 MPG, US gallons equal about 7.84 L/100km while imperial gallons equal about 9.42 L/100km. Price gallons convert independently.
