Formula
How this calculator works
This formula converts source operating values into ari for quick review.
ARI = (Hotel ADR ÷ Comp Set ADR) × 100
Context
Why this metric matters
Index >100 means rate premium over comp set. High ARI with weak MPI may indicate pricing above market absorption.
Hotel insight
Industry context
- Index >100 means rate premium over comp set. High ARI with weak MPI may indicate pricing above market absorption.
- Small changes in denominator rules can move the result, so keep the same reporting basis when comparing periods.
Operational notes
Before you act on the number
- $150 ÷ $145 × 100 = 103.45
- Confirm whether internal-use, complimentary, adjustment, or excluded activity should be included before comparing periods.
- Use this result as an operating guide and review it with the supporting business context.
