📊 MPG Calculator
Knowing your vehicle's true MPG (miles per gallon) is essential for budgeting, comparing vehicles, and understanding your fuel costs. While car manufacturers provide official MPG figures, real-world driving conditions — including traffic, weather, and driving style — often give different results. Our MPG Calculator helps you work out your actual fuel economy.
Whether you're a business owner tracking fleet efficiency, a self-employed driver claiming mileage, or just someone who wants to know their car's real MPG, this calculator gives you accurate results based on your actual driving data.
What our MPG calculator does:
- 📏 Miles Driven — Enter the distance you've travelled since your last fill-up.
- ⛽ Litres Used — Enter the exact litres you've used (from your fuel receipt).
- 📊 MPG Result — Get your vehicle's actual MPG in UK gallons.
- 📋 Trip Tracking — Use it for any trip length to monitor your car's efficiency.
💡 Pro Tip: For the most accurate results, fill your tank to the brim, reset your trip counter, drive as normal, then fill up again. Use the miles driven and litres used to calculate your true MPG. Repeat this process over several fill-ups for an average figure.
