Length Of Stay Average Calculator

Work out length of stay average instantly with clear inputs, formula shown and shareable results.

About Length Of Stay Average Calculator

Average length of stay is room nights divided by arrivals, and raising it reduces the operational cost per room night sold because check-in, check-out and deep cleaning are per-stay rather than per-night activities. A high single-night share is the main drag.

Formulas

Average length of stay

ALOS = Total room nights / Total arrivals

Arrivals at target

Arrivals = Total room nights / Target average stay

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 3 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

Why does ALOS matter commercially?

Because each arrival consumes fixed servicing effort. Selling the same nights to fewer, longer-staying guests is materially cheaper.

How do I raise it?

Minimum-stay restrictions on peak nights, length-of-stay discounts, and packaging that makes an extra night attractive rather than merely cheaper.
