ARI (Average Rate Index)

Definition

ARI measures your ADR against the compset average, expressed as a percentage. If your ADR is €120 and the compset average is €100, your ARI is 120. An ARI of 100 means you’re priced exactly at the compset average.

What it tells you

ARI tells you where you sit on rate. Above 100 = premium positioning; below 100 = discount relative to the set. ARI movement matters more than absolute level — a rising ARI means you’re pulling away on rate; falling means the compset is moving up faster than you.

How to track it

Computed from STR reports (the industry-standard benchmarking service) or equivalent. Requires rate-shopping data on the compset.

Where it fits

One of the three STR indices (ARI, MPI, RGI) on most owner-level reports. The natural companion to compset analysis — when compset performance shifts, ARI catches it.
