Calculating Daily Occupancy rate of hotel

[stampgeorge]

Hello, I want to calculate the daily occupancy of two hotels. Right now, I have two tables, one is named RESORT, with two Columns, Name of Resort and Total Number of Rooms. I also have a table named Statistics, where each row represents a reservation, I also have a column called business date and I have a column with the resort name and a column named Room Nights which is always 1. 

Each row has only 1 reservation. The same reservation is repeated per business date. 

For example, if a guest arrives at 1/6/24 and checks-out at 7/6/24, they have 7 rows, one per night.

I have figured out how to calculate it for today, but not in total.

I also have a reservations table, where each reservation has only 1 row, but there are no business date column. How can I calculate it best?

Thank you!

@stampgeorge Sample data would help tremendously. However, I would think that you could break the problem down along these lines:

Measure = 
  // This measure assumes RESORT[Name of Resort] is in the visual
  // Also, Statistics is related to RESORT based upon the name of the resort
  VAR __Rooms = MAX( 'RESORT'[Total Number of Rooms] )
  VAR __Days = COUNTROWS( DISTINCT( SELECTCOLUMNS( 'Statistics', "date", [business date] ) ) )
  VAR __Reservations = COUNTROWS( 'Statistics' )
  VAR __TotalRooms = __Rooms * __Days
  VAR __Result = DIVIDE( __Reservations, __TotalRooms )
RETURN
  __Result

@Greg_Deckler Thanks! This worked! The thing is, that it shows the correct % per resort, but it doesn't show the correct result for both the resorts. Is there a way to show the total occupancy in both resorts?

This looks like a measure totals problem. Very common. See my post about it here: https://community.powerbi.com/t5/DAX-Commands-and-Tips/Dealing-with-Measure-Totals/td-p/63376
