Work out rail fare per kilometre instantly with clear inputs, formula shown and shareable results.
Fare per kilometre makes journeys of different lengths comparable and exposes tapered fare structures, where the rate per kilometre falls with distance. Setting the monthly cost of singles against a pass price gives the break-even number of journeys, the only figure that decides whether the pass is worth buying.
Fare metrics
fare per km = fare / distance; break-even journeys = pass price / single fare
Rail results are planning estimates only. Verify against the infrastructure manager's rule book, approved braking curves and applicable railway safety regulations.
Most fare tables taper, because a large part of the cost is fixed per journey — booking, station and access costs — rather than proportional to distance.
Yes, count each leg. A commuter making two legs a day needs about 40 legs a month, which is where most passes break even.
