Transit Load Factor Calculator

Work out transit load factor instantly with clear inputs, formula shown and shareable results.

About Transit Load Factor Calculator

Load factor can be measured against seats or against total capacity including standing, and the two tell different stories. A factor above one on seats simply means some passengers stand, which is normal on urban services. A factor approaching one on total capacity means crush loading, at which reliability and dwell times deteriorate sharply.

Formula

Load factors

Seat load factor = passengers / seats; total load factor = passengers / (seats + standing capacity)

Worked example

With the default values below, Transit Load Factor Calculator returns Load factor against seats of 1.1429. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is the Transit Load Factor figure worked out?

Seat load factor = passengers / seats; total load factor = passengers / (seats + standing capacity). Load factor can be measured against seats or against total capacity including standing, and the two tell different stories.

What load factor should a service target?

Urban peak services commonly plan for 0.8 to 0.9 of total capacity, while interurban and rail services with long journey times plan for a seat for every passenger.

What values do I need to enter?

This calculator takes 3 inputs: Passengers carried, Seats offered, Standing capacity offered. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
