Tool Introduction

Work out how much fuel your car really drinks - and what it costs. Choose the data you have: a fuel receipt plus the price per liter, the liters pumped over a known distance, or a full-tank fill-up with the trip meter reset.

You get consumption in liters per 100 km, the US miles-per-gallon figure, liters per km, and - when costs are involved - the price per kilometer and per mile. An efficiency rating puts the number in context, from excellent to very poor. All calculations run in your browser; nothing is uploaded.
