In detail: Road Trip Cost Splitter for a 500-Mile Trip

A 500-mile road trip costs roughly £75.77 in fuel at 45 mpg and £1.50/litre. Split between 3 people that's about £25.26 each. That's the core number — but the useful context is how sensitive it is to the inputs. Change any one of the assumptions by even 10–20% and the final figure can move meaningfully, which is why a calculator like this is better than a rule-of-thumb memorised from a magazine article.

Looking at the alternate scenarios below, the spread tells you how robust (or fragile) your answer is: if small changes produce big swings, plan for the pessimistic case; if it's stable across the range, you can commit more confidently.
