Occupancy Index Calculator
An occupancy index of 100 means you are running neck and neck with your market. Above 110 and you are stealing share; below 90 and the market is filling faster than you are. This calculator benchmarks your occupancy against a competitor or market set, and also runs the two companions every hotelier checks next: occupancy plus vacancy, and the revenue KPIs ADR and RevPAR.

Quick Answer
With 150 of 200 rooms sold (75.00%) against a competitor’s 100 of 150 (66.67%), the occupancy index is 112.50, a share gain. The same hotel at 96 of 120 units runs 80.00% occupancy with 20.00% vacancy, and on $22,500 of room revenue from 150 rooms sold out of 200 available it earns an ADR of $150.00 and RevPAR of $112.50. The calculator above is pre-filled with these exact numbers.
Key takeaways
- The index answers “are we beating the market?”, not “are we full?”. A half-empty hotel in a weak market can still post a strong index.
- 100 is parity with your competitive set. Treat 110 and above as gaining share and below 90 as losing it; the band in between is noise worth watching, not celebrating.
- The verdict needs both percentages shown. An index alone hides whether you won by filling rooms or the market collapsed around you.
- RevPAR is the money metric. A hotel can raise occupancy by slashing prices and still lose money; RevPAR catches the trade.

How to use the occupancy index calculator
Pick the tab that matches your question. The three modes share nothing except the Calculate button, and results stay hidden until you click it.
- Index vs market: enter your sold and total units, then the competitor’s or market’s sold and total for the same dates. The tool shows both occupancy percentages and the index with a share verdict.
- Occupancy + vacancy: enter occupied and total units. You get the occupancy rate and the vacancy rate, which is simply 100 minus occupancy.
- Revenue KPIs: enter room revenue, rooms sold and rooms available. You get ADR, occupancy and RevPAR, the three numbers every hotel revenue report is built on.
If you want your own occupancy rate without any market comparison, the occupancy percentage calculator runs that single calculation. For revenue-weighted thinking, the economic occupancy calculator weighs each unit by what it earns.
The math: index, occupancy, ADR and RevPAR
The index is a ratio of two occupancy rates, multiplied by 100 so it reads like a percentage of fair share. This is the same construction the hotel industry calls Market Penetration Index: your occupancy divided by the competitive set’s occupancy, times 100.
Their occupancy % = Their units occupied ÷ Their total units × 100
Occupancy index = (Your occupancy % ÷ Their occupancy %) × 100
Vacancy % = 100 − Occupancy %
ADR = Room revenue ÷ Rooms sold
RevPAR = Room revenue ÷ Rooms available = ADR × Occupancy
Two behaviours are worth knowing before you trust a number. First, the index is undefined when the competitor’s occupancy is zero; the tool refuses instead of dividing by zero. Second, the ADR line shows $0.00 when rooms sold is zero rather than erroring, because a closed hotel genuinely has no average rate, and RevPAR still computes from rooms available. When these KPIs feed a purchase decision rather than a monthly report, the hotel value calculator turns revenue figures into a property valuation.
Worked example: 150 of 200 rooms against a 100-of-150 rival
The pre-filled run pits your 150 sold of 200 (75.00%) against the market’s 100 of 150 (66.67%). Every line below is the tool’s actual output.
| Tab | Inputs | Result |
|---|---|---|
| Index vs market | You 150/200, them 100/150 | Index 112.50, gaining share (75.00% vs 66.67%) |
| Occupancy + vacancy | 96 occupied of 120 | Occupancy 80.00%, vacancy 20.00% (24 empty) |
| Revenue KPIs | $22,500 revenue, 150 sold, 200 available | RevPAR $112.50, ADR $150.00 at 75.00% occupancy |
Read the index as a position on this band. The band is the tool’s own verdict logic, shown so you can place any reading at a glance:
Occupancy index vs occupancy rate: which one do you need?
Use the rate for operations and the index for strategy. They answer different questions, and mixing them up is the most common mistake on this keyword.
Occupancy rate tells you how full you are: 85% of your rooms are sold. It is the number a front desk manages to, and it feeds staffing, housekeeping and daily pricing. It says nothing about the market. The index tells you whether you are winning: your 85% against a market running 95% is an index of 89.47, a losing share despite looking nearly full. Conversely, 60% occupancy in a 50% market is an index of 120, a strong result from a hotel that looks half-empty.
Most pages ranking for “occupancy index” actually sell you a plain occupancy rate under an index label. If the tool never asks for a competitor’s numbers, it is computing a rate, not an index. Watch the trend, not single readings: one month at 108 proves nothing, but three quarters climbing from 96 to 112 is a strategy working. If you plan events rather than hotel nights, the same market-share thinking applies to room blocks, and the event capacity calculator works the planning side of filling a venue.
What competing calculators miss
The rival set for this keyword splits between rate tools mislabelled as index tools and thin index tools that hide the workings:
- Calculator Ultra’s occupancy rate index calculator: computes the genuine index formula with a worked example, but never shows the two occupancy percentages behind the index, so you cannot see whether you won or the market lost.
- BraveCalculator’s occupancy rate index pages: despite the name, these compute a plain occupancy rate, occupied over total, with no competitor input at all. Calling a rate an index is exactly the confusion this page separates.
- Amenitiz’s occupancy rate calculator: strong hotel context with good benchmarks and FAQs, and honest about the difference between occupancy and RevPAR, but it is a rate tool plus marketing content, not a market benchmark.
- The gap this page fills: the true index with both underlying percentages on screen, share-gain verdicts at stated bands, plus the vacancy figure most rate tools skip and the ADR and RevPAR calculations none of the index competitors attempt.
Frequently asked questions
100 means you are running at parity with your competitive set. Treat 110 and above as gaining share and below 90 as losing it, and track the trend over several months rather than celebrating or panicking over a single reading.
The rate is your fill level: occupied units divided by total units. The index benchmarks your rate against a competitor’s or the market’s: your occupancy percentage divided by their occupancy percentage, times 100. The rate answers “are we full”, the index answers “are we winning”.
Yes. If you run 60% occupancy in a market running 50%, your index is 120. The index measures relative performance against the market, not absolute fullness, which is why a half-empty hotel can still post a strong index in a weak market.
Revenue per available room blends rate and occupancy into one number: room revenue divided by rooms available. A hotel can raise occupancy by slashing prices and still lose money; RevPAR catches that trade, which is why it is the money metric in hotel reporting.
Yes for the index and rate tabs. Units can be apartments, desks, beds or storage units; the math is identical. The Revenue KPIs tab is hotel-specific, but the ADR and RevPAR logic adapts to rent per occupied unit.
Monthly for strategy and quarterly for board-level review. Compute the occupancy rate itself daily or weekly for operations, since staffing and pricing need faster signals than market-share trends do.
Use a market average from a data provider such as STR instead of a single rival. A single competitor is noisy; a market set is stable. Keep the set identical every month, because changing the set moves the index even when nothing real changed.
