Why fuel costs are worth calculating properly

Fuel and energy prices change often, and it's easy to underestimate what a long journey, a daily commute, or running a car for a year actually costs. These calculators use UK units (miles, MPG, pence per litre) and update instantly as you type, so you can plan a road trip, split costs fairly with passengers, or decide whether an electric car would save you money.
