Trip Cost Calculator

All distances, efficiency and prices are supplied by you. No maps, route planning, live prices or currency conversion. Lodging is for the whole group; food and other costs are per person for nights + 1 days. Trips multiply fuel use, fuel cost and tolls only. Each trip has 1 leg, or 2 for a round trip; the entered one-way toll applies equally to each leg. Nights, lodging and daily food/other costs describe the entire stay and are counted once. For removal journeys, set unused non-transport costs to zero. Enter km/L or L/100 km; convert UK imperial mpg first (L/100 km = 282.480936 / UK mpg), never enter mpg directly.

Formula and assumptions

One-way distance: mi × 1.609344 → km; Round trip: × 2; Transport trips: km × Transport trips; Fuel used (L): km ÷ (km/L) = km × (L/100 km) ÷ 100; Fuel cost: L × Fuel price per litre; Total tolls: Toll per one-way leg × Transport trips (Round trip: × 2); Lodging cost: Nights × Lodging per night (whole group); Food cost: (Nights + 1) × Travelers × Food per person per day; Other cost: (Nights + 1) × Travelers × Other cost per person per day; Total trip cost: Fuel cost + Total tolls + Lodging cost + Food cost + Other cost; Cost per person: Total trip cost ÷ Travelers. Trips multiply fuel use, fuel cost and tolls only. Each trip has 1 leg, or 2 for a round trip; the entered one-way toll applies equally to each leg.
