# Sizing the market: US and Europe by the numbers
A pitch deck lands on your desk claiming "the US hotel market is worth $500 billion." Is that true, inflated, or measuring something else entirely? Within thirty seconds you should be able to tell. This lesson gives you that thirty-second sanity check.
"Hotel market size" can mean at least four different things: room revenue only, total hotel spend (rooms plus food, beverage, events), gross booking value through online platforms, or the value of hotel real estate assets. A founder pitching a hotel tech startup and a REIT (Real Estate Investment Trust, a company that owns income-producing property and trades like a stock) analyst valuing buildings are using the same phrase for different numbers. Your first job is always: revenue of what, to whom, over what period?
Three metrics roll up into every hotel revenue figure you'll see.
Occupancy: percentage of available rooms sold. A 200-room hotel selling 150 rooms on a given night has 75% occupancy.
ADR (Average Daily Rate): average price paid per occupied room. Total room revenue divided by rooms sold.
RevPAR (Revenue Per Available Room): the single most-watched hotel metric. Calculated two equivalent ways:
RevPAR = Occupancy % × ADR
RevPAR = Total Room Revenue ÷ Total Available RoomsWorked example: a hotel has 75% occupancy and a $160 ADR.
RevPAR = 0.75 × $160 = $120.
Multiply RevPAR by available room-nights across a whole market and you get total room revenue, the backbone of any credible market-size figure. This is also why RevPAR is the number hoteliers obsess over daily: it captures both pricing power and demand in one figure, unlike occupancy or ADR alone (a hotel can have high occupancy at bargain-basement rates and look "busy" while actually underperforming).
As of 2025-2026 (industry estimates, figures rounded), the US hotel industry is commonly cited at roughly $200-210 billion in annual room revenue, per data from STR (part of CoStar Group), the main benchmarking firm hoteliers and investors rely on for occupancy, ADR and RevPAR data.
Structural facts worth knowing:
Rooms × average occupancy × ADR × 365 ≈ total market room revenue.
5.5 million rooms × 0.64 occupancy × $155 ADR × 365 days ≈ $200 billion. That's how the headline number is actually built, and why it roughly matches STR's reported figures. If a deck claims $500 billion for "the US hotel market," ask whether they've included food and beverage, meetings and events, or bundled in short-term rentals (Airbnb-style stays), which run as a separate multi-billion-dollar layer on top.
Europe has no single "national" hotel market data source like STR's US panel is often benchmarked against; instead, it's a patchwork of country markets with different regulators, currencies (eurozone vs. UK, Switzerland, etc.), classification systems (star ratings aren't standardized across countries), and seasonality patterns.
Rough scale, by estimate:
This is the key contrast to remember: the US market is a story of scale and brand consolidation; Europe is a story of fragmentation, country-level variance and independent ownership. Any pitch that treats "Europe" as one homogeneous market the way you might treat the US is oversimplifying.
Knowledge check
1. A pitch deck claims 'the US hotel market is worth $X billion.' Before evaluating whether the number is reasonable, what is the most important question to ask?
2. Why is RevPAR considered more informative than occupancy or ADR alone when evaluating hotel performance?
3. A hotel tech startup founder and a REIT analyst are both citing 'the hotel market size' but arrive at very different numbers for the same country. What is the most likely explanation?
4. Select ALL correct answers about how RevPAR can be calculated or interpreted.

Year-over-year RevPAR growth is the headline metric analysts quote on every earnings call from Marriott, Hilton, Accor and IHG. Watch whether growth is coming from occupancy (more room-nights sold, a demand signal) or ADR (pricing power, which can mask flat or declining demand). Post-2023 recovery cycles have shown ADR-led growth in many markets, meaning revenue looks healthy while occupancy still trails pre-2019 levels in some segmentssegmentsDividing a market into distinct groups of customers who share similar needs, characteristics or behaviours, so each group can be served with a tailored approach.View full definition → (notably US urban/business travel).
Also check RevPAR versus inflation. Nominal RevPAR growth of 3-4% during a period of similar overall inflation is roughly flat in real terms, not genuine sector growth. This is one of the most common places pitch decks quietly inflate a growth story.
1. Revenue of what? Rooms only, or total hotel revenue (add F&B, events)?
2. Which geography, precisely? "Europe" spanning 44 countries is not one market.
3. Chain scale vs. independent: does the claim assume brand-level distribution economics that don't apply to the independent majority?
4. Source and date
5. Does the RevPAR math tie out? Occupancy × ADR should equal the RevPAR quoted. If it doesn't, the deck is mixing time periods or datasets.
