ROI Calculator: How Fast Green Choice Pays for Itself in a Hotel

Three calculation examples for 50, 150, and 500+ rooms. Here's how fast Green Choice pays off.
Why an ROI calculator helps with the decision
Before hotels invest in new technology, they rightly ask: does it pay off? With Green Choice, this question can be answered with unusual precision — because the savings are directly measurable and start from day one.
The variables in the calculation
Three factors determine the ROI of Green Choice: the number of rooms and occupancy, the average cost per cleaning (8-15 euros depending on hotel category), and the opt-out rate or chosen operating model. In the opt-out model, Green Button customers achieve an average skip rate of around 40 percent. In the opt-in model, savings of up to 70 percent are possible.
Calculation example 1: small boutique hotel with 50 rooms
50 rooms at 70 percent occupancy result in 12,775 occupied room-nights per year. Conservatively calculated with a 25 percent opt-out rate, 3,194 cleanings are saved. At an average of 12 euros per cleaning, that's an annual saving of around 38,300 euros. With an average skip rate of around 40 percent in the Green Button opt-out model, the savings potential is correspondingly higher. On top of that come savings in water (approx. 160,000 liters), electricity, and cleaning supplies.
Depending on hotel size, occupancy, and operating model, the Green Choice implementation often pays for itself within a few months.
Calculation example 2: city hotel with 150 rooms
150 rooms at 75 percent occupancy: 41,063 occupied room-nights. At a 25 percent opt-out rate, 10,266 cleanings are skipped. Savings at 13 euros per cleaning: around 133,500 euros annually. That's equivalent to roughly 2.5 full-time housekeeping positions.
Calculation example 3: hotel group with 500+ rooms
For a hotel group with 500 rooms across multiple properties and 78 percent occupancy, that's 142,350 occupied room-nights. At a 25 percent opt-out rate: 35,588 saved cleanings. Annual savings at 14 euros per cleaning: around 498,000 euros. On top of that come savings in water (over 1.7 million liters) and a significantly improved CO₂ footprint.
Additional savings that are often forgotten
Direct cleaning cost savings are only part of the picture. Fewer cleanings also mean: less textile wear (towels, bed sheets), less coordination effort for the housekeeping manager, better guest reviews due to fewer disruptions, and a measurable sustainability contribution for ESG reports.
Conclusion: the numbers speak for themselves
The numbers speak a clear language: Green Choice pays for itself in weeks, not months. Whether small boutique hotel or large hotel group — the savings potential is significant proportional to hotel size. And unlike many investments, there's no risk here: fewer unnecessary cleanings are always a good decision.
Frequently asked questions
How quickly does Green Choice pay for itself?
In most hotels, within a few weeks of introduction, depending on hotel size and occupancy.
What opt-out rate is realistic?
In the opt-out model, Green Button customers achieve an average skip rate of around 40 percent. In the opt-in model, savings of up to 70 percent are possible depending on hotel operations.
How do I calculate the savings for my hotel?
Multiply your occupied room-nights by the expected opt-out rate (25 percent as a benchmark) and your average cleaning cost per room. For an individual calculation, contact the XINGULAR team.
