How the Road Trip Fuel Stops Calculator works
Usable range = full-tank range × (1 − reserve ÷ 100). Stops = ceil(distance ÷ usable range) − 1, because you start with a full tank. Example: with Trip distance 900 km, Range on a full tank 550 km, and Safety reserve 15%, the result is Fuel stops needed = 1; Usable range per tank (km) = 467.5; Distance before the first stop (km) = 467.5.
