RevPAR, ADR, and Occupancy Rate: Core Hospitality Metrics

RevPAR, ADR, and occupancy rate are the three foundational performance metrics used across the commercial lodging industry to evaluate revenue efficiency, pricing strength, and demand capture. Understanding how these metrics are defined, calculated, and interrelated is essential for operators, asset managers, investors, and analysts working within any segment of the US hospitality market. This page provides a comprehensive reference treatment of all three metrics, including their mechanics, causal drivers, classification boundaries, common misconceptions, and comparative context.

Definition and Scope

RevPAR (Revenue Per Available Room) is the single most widely cited performance indicator in commercial lodging. It represents the revenue a property generates per available room per night, regardless of whether that room was sold. RevPAR integrates both pricing and occupancy into a single figure, making it the standard metric for benchmarking competitive set performance and evaluating revenue management effectiveness across hotel classifications and segments.

ADR (Average Daily Rate) measures the average rental income received per occupied room per day. Unlike RevPAR, ADR only reflects rooms that were actually sold — it does not account for unsold inventory.

Occupancy Rate expresses the percentage of available rooms that were sold during a given period. It is a pure demand metric: it captures how effectively a property fills its room inventory but carries no information about the rate at which rooms were sold.

Together, these three metrics form the foundational triangle of hotel performance analysis. STR (a CoStar Group company and the primary benchmarking data provider for the US lodging industry) collects and publishes these metrics across tens of thousands of properties and uses them as the basis for competitive set benchmarking reports.

Core Mechanics or Structure

RevPAR

RevPAR is calculated by two equivalent formulas:

Formula 1: RevPAR = Total Room Revenue ÷ Total Available Rooms

Formula 2: RevPAR = ADR × Occupancy Rate

Both formulas yield identical results. The second formula exposes the multiplicative relationship between ADR and occupancy — a critical structural feature of the metric.

Example: A 200-room hotel generates $40,000 in room revenue on a given night.
- RevPAR = $40,000 ÷ 200 = $200.00
- If ADR is $250 and occupancy is 80%, then RevPAR = $250 × 0.80 = $200.00

ADR

ADR = Total Room Revenue ÷ Total Rooms Sold (Occupied Rooms)

ADR excludes complimentary rooms, staff rooms, and out-of-order rooms from both numerator and denominator. The precise exclusion methodology can vary by property management system configuration, but the STR methodology excludes complimentary rooms from revenue and from the occupied room count.

Occupancy Rate

Occupancy Rate = Rooms Sold ÷ Rooms Available × 100

Available rooms in the denominator exclude rooms that are out of order (OOO) due to maintenance or renovation — these rooms are removed from the denominator for the duration of the OOO period. This distinction matters significantly for properties undergoing phased renovation, where available inventory fluctuates throughout the measurement period.

TRevPAR and Beyond

A related metric — TRevPAR (Total Revenue Per Available Room) — expands the numerator to include all revenue streams: food and beverage, spa, parking, resort fees, and ancillary charges. TRevPAR is particularly relevant in full-service hotel and resort contexts where non-room revenue is substantial.

Causal Relationships or Drivers

RevPAR is jointly determined by ADR and occupancy. The drivers that influence each component differ and can conflict.

Drivers of Occupancy Rate

• Demand segments: Leisure, corporate transient, group, and government segments each contribute differently to occupancy across different days of week and seasons. Seasonality and demand patterns have a direct and measurable effect.
• Distribution channel mix: Properties with strong presence on online travel agencies and global distribution systems typically achieve higher occupancy at the cost of higher distribution fees.
• Competitive supply: New hotel openings within a competitive set directly compress occupancy for incumbent properties by distributing the same demand pool across more available rooms.
• Event and group demand: A single citywide convention can drive occupancy above 90% across an entire market for a limited period.

Drivers of ADR

• Rate tier positioning: Brand classification, quality tier, and perceived value anchor the rate ceiling for a given property relative to its competitive set. Hotel brand families and flag affiliations influence rate perception directly.
• Length of stay: Longer stays are often associated with lower negotiated rates, reducing ADR even while supporting occupancy.
• Revenue management practices: Dynamic pricing algorithms, rate fencing, and channel rate parity enforcement all affect ADR. Revenue management strategy is the primary operational lever for ADR optimization.
• Discount depth: Deep discounting to fill rooms raises occupancy but suppresses ADR, compressing the RevPAR benefit.

The Multiplicative Effect

Because RevPAR = ADR × Occupancy Rate, a 10% gain in ADR at constant occupancy produces the same RevPAR increase as a 10% gain in occupancy at constant ADR. However, volume-driven occupancy gains typically require lower rates to attract incremental demand, making pure occupancy-driven RevPAR growth often less profitable than rate-driven growth on a net operating income basis.

Classification Boundaries

These metrics apply at multiple levels of aggregation, and the classification of what is "available" determines the denominator across all three:

STR classifies US hotels into six chain scales — Luxury, Upper Upscale, Upscale, Upper Midscale, Midscale, and Economy — and publishes RevPAR, ADR, and occupancy benchmarks by chain scale, market, and submarket. These classifications determine the peer group against which a property's metrics are evaluated.

RevPAR Index (MPI, ARI, RGI): Benchmarking services calculate three derivative indices:
- MPI (Market Penetration Index): Property Occupancy ÷ Comp Set Occupancy × 100
- ARI (Average Rate Index): Property ADR ÷ Comp Set ADR × 100
- RGI (Revenue Generation Index): Property RevPAR ÷ Comp Set RevPAR × 100

An index of 100 indicates exactly fair share. Above 100 indicates outperformance; below 100 indicates underperformance relative to the competitive set. These indices are the standard output of STR STAR reports, which are the industry-standard benchmarking product.

Tradeoffs and Tensions

Occupancy vs. Rate: The Core Tension

Filling rooms at any price increases occupancy and may improve RevPAR in the short term. But aggressive discounting conditions the market to lower rate expectations, erodes ADR over time, and introduces high variable costs (housekeeping, amenity delivery, utility load) that reduce gross operating profit. Revenue management in commercial hospitality is fundamentally a discipline of managing this tension through controlled rate acceptance by segment.

RevPAR vs. Profitability

RevPAR does not measure profitability. A property can achieve high RevPAR while operating at a loss if fixed costs, labor costs, or debt service are disproportionately high. Gross Operating Profit Per Available Room (GOPPAR) is a more complete profitability indicator, but it is less standardized and less universally reported than RevPAR.

Short-Term RevPAR vs. Guest Experience

Maximizing RevPAR through last-minute rate spikes or overselling can damage guest experience standards and generate negative reviews that suppress future demand. This is a structural tension: revenue optimization models optimize for near-term revenue, while brand value and repeat business depend on consistent guest satisfaction.

Group vs. Transient Mix

Group bookings fill occupancy at negotiated rates and typically produce lower ADR than transient bookings. However, group business provides displacement protection — rooms sold in advance at a known rate reduce revenue uncertainty. The optimal group-to-transient ratio depends on the property's cost structure, demand variability, and market position.

Common Misconceptions

Misconception 1: High occupancy means strong performance.
A property running 95% occupancy at rates 30% below its competitive set is underperforming on RevPAR and likely on profitability despite high room utilization. Occupancy in isolation conveys nothing about rate quality or revenue efficiency.

Misconception 2: RevPAR includes all hotel revenue.
RevPAR is a rooms-only metric. Food and beverage, spa, resort fees, and parking revenue are excluded from the standard RevPAR calculation. TRevPAR or Total Revenue benchmarks must be used for whole-property performance evaluation — particularly important for casino hospitality and full-service resort contexts.

Misconception 3: ADR is the same as rack rate.
Rack rate is the published maximum rate. ADR is the realized average across all sold rooms — it reflects the blend of rack, negotiated corporate, OTA, group, government, and promotional rates. ADR is almost always lower than rack rate.

Misconception 4: RevPAR index above 100 means the property is profitable.
An RGI above 100 means the property is capturing more than its fair share of market revenue relative to the competitive set. It does not account for cost structure. A property with a 110 RGI and excessive fixed costs can still post a net operating loss.

Misconception 5: Occupancy rate denominator is always total rooms in the building.
Out-of-order rooms are excluded from the available rooms denominator. A 300-room property with 20 rooms undergoing renovation has 280 available rooms, not 300. Failing to apply this correctly overstates available inventory and understates calculated occupancy and RevPAR.

Checklist or Steps

Metric Calculation Verification Sequence

The following sequence identifies where errors most commonly occur when calculating or auditing RevPAR, ADR, and occupancy rate at the property level:

1. Confirm the available room count — Subtract out-of-order (OOO) rooms from total physical rooms. Verify OOO log against property management system records.
2. Confirm the occupied room count — Exclude complimentary rooms per the STR methodology. Verify that staff rooms and house-use rooms are excluded from both numerator and denominator for ADR.
3. Calculate rooms revenue — Pull from the rooms revenue line of the property management system night audit report. Exclude food and beverage, resort fee pass-throughs (where applicable), and ancillary charges.
4. Calculate ADR — Divide confirmed rooms revenue by confirmed occupied room count.
5. Calculate occupancy rate — Divide confirmed occupied room count by confirmed available room count. Multiply by 100 for percentage expression.
6. Calculate RevPAR via Formula 1 — Divide total rooms revenue by total available rooms.
7. Verify via Formula 2 — Multiply ADR × Occupancy Rate (as a decimal). Compare to Formula 1 result; any discrepancy indicates a data inconsistency in the source inputs.
8. Compare to STR STAR report — Match the property's self-reported figures against the STR STAR report for the same period. Investigate discrepancies greater than 0.5 percentage points in occupancy or $1.00 in ADR.
9. Calculate index metrics — Divide property metrics by competitive set averages (from STR report) to produce MPI, ARI, and RGI. Confirm comp set composition is current and reflects the intended peer group.
10. Document the period and time zone — All three metrics are calculated for a specific date or date range. Confirm that checkout conventions (e.g., midnight cutoff vs. 11:00 AM) are applied consistently across the full measurement period.

Chain Scale Benchmarking Context (STR Classifications)

Note: ADR ranges are structural and relative — they reflect tier positioning, not absolute dollar values, which vary significantly by market. STR publishes absolute benchmarks by chain scale and market in its monthly Trend reports.
