What MPI, ARI and RGI mean
These three indexes compare your hotel with a competitive set of similar hotels nearby. A score of 100 means you earn exactly your fair share; above 100 means you outperform the market, below 100 means competitors are winning. This free calculator works them out from your occupancy and ADR and your competitive set's figures.
| Index | Formula | Measures |
|---|---|---|
| MPI | Your occupancy ÷ comp set occupancy × 100 | Share of demand |
| ARI | Your ADR ÷ comp set ADR × 100 | Price position |
| RGI | Your RevPAR ÷ comp set RevPAR × 100 | Overall revenue share |
How to read the result
- High ARI, low MPI: you may be priced too high for your reviews or content.
- High MPI, low ARI: you fill rooms but leave money on the table — raise rates on high-demand dates.
- RGI above 100: you are beating the market; protect it with consistent pricing.

Frequently asked questions
Where do I get competitor occupancy data?
Benchmarking services collect anonymised data from hotels in a market. Without them, estimate from rate shopping, OTA availability and local knowledge, and treat the result as a guide.
What is a good RGI?
An RGI above 100 means you earn more than your fair share of revenue in your competitive set. Consistently improving RGI is a strong sign your pricing and distribution are working.
Which hotels should be in my competitive set?
Four to six nearby hotels that guests genuinely compare with yours — similar category, price range and location.
