Real-World MPG Calculator
Official test-cycle MPG figures are not real MPG. NEDC-era tests (pre-2020 cars) overstate real economy by roughly 20-25%; the newer WLTP test still overstates it by around 10-14%. Enter your car’s official figure and year to see what you’ll actually get.

This is an estimate based on typical NEDC/WLTP test-vs-reality gaps, not a measurement of your specific car — real-world MPG varies with driving style, load and conditions.
