Rider Requirement Calculator

Work out rider requirement instantly with clear inputs, formula shown and shareable results.

About Rider Requirement Calculator

Rider requirement follows from trips per hour multiplied by round trip duration, divided by the utilisation you can realistically sustain. Targeting 100% utilisation guarantees late deliveries, because orders arrive unevenly and riders need slack to absorb clustering.

Formulas

Trips per hour

Trips = Peak orders per hour / Orders per trip

Riders required

Riders = ceiling(Trips per hour x Round trip minutes / 60 / Target utilisation)

Worked example

With the default values below, Rider Requirement Calculator returns Riders required at peak of 17. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 4 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 2 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

What utilisation is realistic?

70-80% at peak. Above that, waiting time for dispatch grows quickly and promised delivery windows start to slip.

How does batching change the answer?

It reduces trips directly, so raising orders per trip from 1.2 to 1.8 cuts rider requirement by a third at the same order volume.
