How the results are calculated
Single trip: fuel = distance × economy (metric L/100 km or US mpg), then × pump price. Buffer increases fuel quantity once per segment — it is not applied again to the money total.
Two segments: each segment is priced separately, then fuel and cost are summed and multiplied by trip count.
This is trip fuel only — not tolls, parking or full ownership cost (TCO).
Using this motoring calculator
- Quick mode: distance, economy and pump price — a fast single-trip budget.
- Advanced mode: two segments, adjustment, buffer, repeat trips and optional split between people.
- The segment chart appears only when two segments are active.
- Carry the figure into fuel consumption, annual running cost or TCO.
