Sizing the market: US and Europe by the numbers

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).

US market: the headline numbers

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:

• The US has around 5.5 million hotel rooms (estimate, American Hotel & Lodging Association, AHLA).
• National average occupancy typically sits in the 63-66% range annually (estimate; it dips well below during downturns and spikes in peak leisure season).
• National ADR is commonly cited around $155-160 (estimate, 2024-2025 range).
• Roughly 70% of US hotels operate under a franchise brand (Marriott, Hilton, IHG, Choice, Wyndham) but are owned by independent real estate owners, not the brand companies themselves. This owner/operator/brand split is the single most misunderstood fact in the sector.

Quick sanity check formula

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: fragmentation is the story

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:

• Europe overall has roughly 14-15 million hotel rooms across all countries, more fragmented in ownership than the US, with a much higher share of independent, family-run properties, especially in Southern Europe (Italy, Greece, Spain).
• Combined European hotel revenue is frequently estimated in the €150-170 billion range annually, though this figure is far less standardized than the US one and varies significantly by source and year.
• The largest single markets are typically the UK, Germany, France, Spain and Italy, each with materially different occupancy and ADR profiles. Southern European coastal markets show extreme seasonality (summer peak occupancy above 85-90% versus winter troughs), while major gateway cities like London and Paris run flatter, business-and-leisure-blended demand curves year-round.
• Branded/chain penetration in Europe is much lower than the US, commonly estimated at under 25-30% of rooms versus roughly 70% branded in the US. Independent hotels dominate.

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.

Essential acronyms to keep straight

• ADR: Average Daily Rate
• RevPAR: Revenue Per Available Room
• STR: the benchmarking data provider (now part of CoStar) most cited for occupancy/ADR/RevPAR
• GOP (Gross Operating Profit): hotel profit after operating expenses but before fixed charges like rent, insurance, and depreciation. Comparable across properties via USALI (Uniform System of Accounts for the Lodging Industry), the standard chart-of-accounts framework hotels use for comparable P&L reporting.
• RGI (RevPAR Generation Index), sometimes called RevPAR Index or MPI: a hotel's RevPAR versus its direct competitive set, expressed as an index around 100. An RGI of 110 means outperforming the local competitive set by 10%.
• OTA: Online Travel Agency (Booking.com, Expedia). Commission-based distribution channel, typically 15-20% commission per booking (estimate, varies by contract).
• GDS: Global Distribution System, the legacy booking infrastructure (Sabre, Amadeus, Travelport) still central to corporate and travel-agent bookings.

Growth signals and how to read them

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.Voir la définition complète → (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.

Due diligence checklist for any market-size claim

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: STR, AHLA, national tourism boards, or an unnamed "industry report"? For a free, credible starting point on US data context, see the U.S. Travel Association's research hub.

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.

Key Takeaways

• RevPAR = Occupancy % × ADR is the core formula underlying every hotel revenue figure; always check that a claimed RevPAR ties back to its occupancy and ADR inputs.
• US hotel room revenue is commonly estimated around $200-210 billion annually (STR/AHLA-based estimates), built from roughly 5.5 million rooms, ~64% occupancy, and ~$155-160 ADR.
• Europe has no single unified data source; it's a fragmented patchwork of ~14-15 million rooms across countries with very different seasonality, ownership structure, and branded penetration (estimated under 30% vs. ~70% in the US).
• Always interrogate market-size claims for scope (rooms vs. total revenue), geography precision, and data source/date before trusting the headline number in any pitch deck.
• Distinguish occupancy-led growth (real demand) from ADR-led growth (pricing power), and check RevPAR growth against inflation to see if a "growth story" is real in nominal or real terms.
