THE NUMBERS, EXPLAINED
How to use this calculator.
Contribution target is before fixed hotel overhead. All cleaning visits, including checkout if needed, must be counted explicitly.
Start with your inputs
Enter long-stay nights, utilities per occupied night (currency), cleaning visits during stay, cost per cleaning visit (currency), booking commission (%), desired stay contribution (currency). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Long-stay nights | 14 |
| Utilities per occupied night (currency) | 5 |
| Cleaning visits during stay | 2 |
| Cost per cleaning visit (currency) | 20 |
| Booking commission (%) | 10 |
| Desired stay contribution (currency) | 250 |
A worked example
With the example inputs above, stay variable cost (currency) is 110. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Stay variable cost (currency) | 110 |
| Required nightly rate (currency) | 28.571429 |
| Required gross stay revenue (currency) | 400 |
How this is calculated
Stay variable cost (currency)
Combine nightly utilities and planned cleaning visits.
Required nightly rate (currency)
Gross up costs and desired contribution for commission, then divide by nights.
Required gross stay revenue (currency)
Calculate revenue that leaves the requested contribution after commission.

Questions about this tool
What does the result tell me?
Stay variable cost (currency); Required nightly rate (currency); Required gross stay revenue (currency). The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Contribution target is before fixed hotel overhead. All cleaning visits, including checkout if needed, must be counted explicitly.
