About Tour Guide Ratio Calculator

Guide-to-guest ratios are driven by safety and audibility, not economics: adventure activities require roughly one guide per ten participants, walking tours around one per 25, and coach tours can run one guide for a full coach because the microphone carries.

Formulas

Guides required

Guides = ceiling(Group size / Maximum group per guide)

Guide cost per guest

Cost per guest = Guide cost per departure / Group size

Worked example

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

Are ratios legally mandated?

For adventure and water-based activities, frequently yes, and insurance cover usually depends on adhering to them.

Why do larger groups get cheaper per guest?

Because guide cost is a step function: it stays flat until the ratio limit is crossed, so per-guest cost falls until the next guide is needed.
