Fuel & Trip
Reckonersweight 1reckoner · computes, doesn't store
Before a long drive there is always the same quiet sum: how far, how thirsty the car, what petrol costs these days. Fuel & Trip does that arithmetic — what the journey will drink and what the drinking will cost — before you commit to visiting the in-laws by road. It computes the figure and keeps no record of where you were thinking of going.
This is not a screenshot. It's the real tool, running right here — go on, put something in it.

Questions people ask
How do I calculate fuel cost for a road trip?
Give it the distance, your car's consumption, and the fuel price, and it tells you what the trip will cost. Run it both ways and you have the round-trip figure before you have found your keys.
Does this trip calculator track my location or my journeys?
Neither. It is a single HTML file running offline in your browser — no maps, no GPS, no account. It computes your sums on the spot and stores nothing; your travel plans never leave the page.
Can I use it to compare driving against the train?
Yes, in the practical sense: it gives you the honest cost of driving, and you hold that number up against the ticket price. Sometimes the train wins, and now you have the arithmetic to say so.
