Hotel Room Revenue per Available Unit Calculator

This calculator measures hotel room revenue per available room, commonly called RevPAR when the revenue input is room revenue. It combines pricing and occupancy into one metric by spreading room revenue across every room-night available for sale, whether occupied or not.

Because it normalizes revenue by inventory, the result is useful for comparing periods or properties with different occupancy levels. The calculator also shows occupancy and average daily rate from the same inputs, making it easier to see whether a change in revenue per available room came from pricing, volume, or both.

1. Enter room revenue
Use recognized room revenue for the period, excluding unrelated departments if you want standard RevPAR.

2. Enter rooms sold
Add occupied room nights actually sold during the period.

3. Enter available rooms
Use the number of rooms that were available for sale each day under the simplified constant-inventory model.

4. Enter days in the period
Use the same date range as the revenue and rooms-sold data.

5. Review RevPAR, occupancy, and ADR
Read the three metrics together to understand the balance between room rate and sold-room volume.

Available room nights = Rooms available × Days RevPAR = Room revenue ÷ Available room nights Occupancy % = Rooms sold ÷ Available room nights × 100 ADR = Room revenue ÷ Rooms sold

Room revenue — recognized lodging room revenue

Rooms sold — occupied room nights sold

Available room nights — sellable room inventory across the period

ADR — average daily rate based on rooms sold

Assumptions: The model assumes the entered room count is available throughout the period. If rooms are out of order or inventory changes, use the actual available room-night count in a more detailed calculation.

What the result means

The main result summarizes the selected metric using the values entered above. Review the supporting figures to understand the operating drivers behind it.

Use consistent periods and units when comparing results. Actual operating results can differ from estimates because of mix, timing, pricing, and cost behavior.

Given

  • $486,000 room revenue
  • 2,880 rooms sold
  • 125 rooms
  • 30 days

Calculation
Available room nights = 125 × 30 = 3,750. RevPAR = $486,000 ÷ 3,750 = $129.60. Occupancy = 2,880 ÷ 3,750 × 100 = 76.8%. ADR = $486,000 ÷ 2,880 = $168.75.

Result
$129.60 RevPAR.

The property generated $129.60 of room revenue for each available room-night, supported by 76.8% occupancy and a $168.75 ADR.

Is revenue per available room the same as ADR?

No. ADR divides room revenue only by rooms sold, while RevPAR divides it by all available room nights.

Should resort fees be included?

Use the revenue definition your reporting system applies consistently. Standard industry comparisons often focus on room revenue, so keep treatment consistent across periods.

How does occupancy affect RevPAR?

At a fixed ADR, higher occupancy raises RevPAR because more available inventory produces room revenue.

Can RevPAR rise when occupancy falls?

Yes. A sufficiently large increase in ADR can offset lower occupancy, which is why the supporting metrics should be reviewed together.

What if some rooms were out of service?

For a precise metric, available room nights should reflect actual sellable inventory. A constant room-count input may overstate availability when rooms were out of order.
