Revenue Per Available Night (or RevPAR) gives you a snapshot of how well your listing is booking and for how much by incorporating your revenue and occupancy for a given month.
To calculate the Revenue Per Available Night, you would take the total amount of revenue including cleaning fee and divide that by the number of bookable nights for each month.
Example
Your listing earned $3,000 last month and you only had 25 days available.
$3000 / 25 days = $120 per day is your RevPAR.
