What is Average Rate Index (ARI)?

Updated 2026-05-28

Average Rate Index (ARI) is a key performance indicator (KPI) used in revenue management to measure how a property's rates compare to the average rates of its competitors. Calculated by dividing your property's Average Daily Rate (ADR) by the ADR of your competitive set and multiplying by 100, it provides a clear benchmark of pricing performance.

An ARI of 100 means your rates are on par with the market, a score above 100 indicates you are priced higher, and below 100 means you are priced lower.

How it works

To calculate ARI, a host or property manager first identifies a 'competitive set'—a group of similar properties in the same geographical area. They then collect the ADR for their own property and the average ADR for the competitive set over a specific period (e.g., a month, quarter).

The formula applied is: (Your Property's ADR / Competitive Set's ADR) x 100 = ARI. This data is typically sourced from specialized market data tools or integrated within property management software.

For instance, platforms with dynamic pricing features often use this market data to help hosts optimize their pricing strategy.

Why it matters

ARI provides essential context for a property's pricing strategy, making it a critical metric for effective revenue management. A high ADR is not inherently positive without knowing how it stacks up against competitors; ARI clarifies whether you are leading the market or simply following a market-wide rate increase.

This index empowers hosts to make data-driven decisions, adjusting rates to either maximize revenue when demand is high or increase occupancy by remaining competitive during slower periods.

Examples

  • A host's mountain cabin has an ADR of $350 for the peak ski season. The average ADR for similar cabins in the area is $320. The host's ARI is ($350 / $320) * 100 = 109.4, indicating their pricing is almost 10% higher than the direct competition.
  • During the off-season, a beachfront condo owner lowers their ADR to $180 to attract bookings. The market average for their comp set is $225. Their ARI is ($180 / $225) * 100 = 80, showing a deliberate strategy to price 20% below the market to boost occupancy.
  • A property manager reviews a portfolio and finds a city apartment has an ARI of 92 during a major conference week. This signals a missed opportunity, as their pricing was 8% below the market average when demand was at its highest, prompting a strategy review for future events.
  • A new luxury rental is priced with an ARI of 115 to establish a premium position. The host monitors bookings closely to ensure this higher rate doesn't negatively impact their occupancy rate compared to the market.

Frequently asked questions

What is considered a good Average Rate Index (ARI)?+
An ARI of 100 means your rates are aligned with your competitive set. An ARI above 100 is often considered favorable, as it shows you are capturing a higher rate. However, a 'good' ARI is relative to your goals; a very high ARI combined with low occupancy might be less profitable than an ARI of 95 with a high occupancy rate.
How is ARI different from RevPAR?+
ARI focuses exclusively on rate performance by comparing your ADR to your competitors' ADR. In contrast, RevPAR (Revenue Per Available Room) measures your own property's overall revenue efficiency by multiplying your ADR by your occupancy rate. They are often analyzed together for a complete performance picture.
Where can I find my competitive set's ADR data?+
Data for a competitive set's Average Daily Rate is available through specialized short-term rental data platforms like AirDNA, PriceLabs, and Wheelhouse. Many modern property management systems also integrate this data into analytics and reporting dashboards to simplify the process.
Should a vacation rental's ARI always be above 100?+
Not necessarily. While an ARI over 100 indicates strong rate performance, it's not always the optimal strategy. For instance, a property might intentionally price with an ARI below 100 to quickly build occupancy, attract initial reviews for a new listing, or penetrate a highly competitive market.
