MPG Calculator

Understanding your vehicle's fuel economy can save you significant money over time. A car with good MPG (40+ UK MPG) could save you £500-£1,000 annually compared to an inefficient vehicle. For a typical driver covering 12,000 miles yearly, even a 5 MPG improvement can save over £150 annually at current fuel prices.

Fuel-efficient vehicles produce fewer carbon emissions. Each gallon of petrol burned produces about 10kg of CO2. Improving your MPG by just 5 miles per gallon can reduce your carbon footprint by approximately 1-2 tonnes of CO2 per year, equivalent to planting 50 trees.

Poor fuel economy often indicates underlying mechanical issues. Monitoring your MPG can help detect problems early, potentially avoiding expensive repairs. Well-maintained vehicles with good fuel efficiency typically have longer lifespans and better resale value.

Many regions have implemented or are planning emissions-based taxation systems. In the UK, Vehicle Excise Duty (road tax) is directly tied to emissions for newer vehicles. Understanding your MPG helps estimate your vehicle's emissions and potential tax implications.

With fuel prices subject to significant fluctuations and the trend toward stricter emissions standards, driving an efficient vehicle provides more stability in your transportation costs. Low-MPG vehicles may face increasing restrictions in urban areas as cities implement clean air zones.
