JJ Ben-JosephThe modern office is undergoing a quiet revolution. Remote work, hybrid schedules, and rising real estate costs force organizations to reconsider how they allocate space. One increasingly popular approach is hot-desking, where employees share a pool of workstations instead of owning a permanent desk. Yet deciding whether to switch from dedicated seating to hot desks is not trivial. The cost of desks, chairs, and floor space is tangible, but determining how many shared seats you truly need requires a bit of math. This calculator bridges that gap by quantifying the financial impact. Enter the total number of employees, the average percentage of staff present on any given day, and the monthly costs associated with each desk and the square footage it occupies. The tool computes how much you would spend under a traditional setup where every employee has a personal desk and compares it with a hot-desking arrangement sized to your actual attendance.
Unlike general office cost estimators, this page zeroes in on one of the most pressing questions for facility managers: can we shrink our footprint without stifling productivity? Many online discussions debate the cultural pros and cons of hot-desking, yet hard numbers are scarce. By offering an interactive model alongside detailed explanations, worked examples, and considerations, this calculator fills an important niche. Whether you are a startup trying to stretch limited funds or a large organization facing a lease renewal, the data provided here helps guide your strategy.
The difference between dedicated and hot desks can be described with a simple formula. The cost of giving everyone a permanent desk is the number of employees multiplied by the combined desk and space cost per workstation. For hot desks, you multiply the number of desks needed—which equals the number of employees times the average attendance rate—by the same per-desk cost. In MathML, the monthly cost of a dedicated layout is:
where Cd is the dedicated cost, E the number of employees, C the cost of furniture per desk, and S the space cost per desk. For hot desks the expression becomes:
where U is utilization expressed as a fraction between 0 and 1. The savings are simply the difference between these two costs. The calculator uses the ceiling function when determining how many hot desks are needed so that you never run short on seats.
Suppose a company employs 100 people. Each desk and chair cost $150 per month, and the office lease equates to $300 of space per desk. Historically, only 60% of staff show up on any given day. With dedicated seating the monthly bill is 100 employees × ($150 + $300) = $45,000. A hot-desking policy sized for 60% attendance needs only 60 desks, resulting in 60 × ($150 + $300) = $27,000. The savings amount to $18,000 per month, or $216,000 annually. Those numbers help stakeholders grasp the stakes and motivate change management efforts.
| Utilization | Dedicated Cost | Hot Desk Cost |
|---|---|---|
| 50% | $45,000 | $22,500 |
| 60% | $45,000 | $27,000 |
| 80% | $45,000 | $36,000 |
The table shows how sensitive the outcome is to attendance. As utilization rises, the savings from hot-desking shrink because you need more desks to accommodate the crowd. When attendance hits 80%, hot-desking still saves $9,000 but offers less flexibility. Such comparisons help determine whether to invest in reservation software, more collaboration zones, or perhaps a mixed approach with some dedicated offices and a hot desk area.
While the calculator captures core financial metrics, it does not address cultural or operational factors. Hot-desking can hinder team cohesion, reduce opportunities for spontaneous collaboration, or cause frustration if employees struggle to find space. Organizations may incur additional costs for lockers, digital reservation systems, or enhanced cleaning regimes. Likewise, the space cost per desk is averaged across the entire office and may not reflect variations in real estate markets or amenity-laden floors. The calculation assumes that attendance is independent day-to-day, yet in reality employees may cluster around midweek meetings, causing temporary seat shortages. As with any financial model, use these results as a starting point for conversation rather than the final word.

The move toward hot-desking is often part of a broader shift to activity-based working, where environments are tailored to specific tasks rather than individuals. That means creating quiet zones, collaboration rooms, and touchdown spaces where employees can work according to their needs. Cost savings from hot-desking can fund these improvements, but they also raise the bar for facility management. Reliable Wi-Fi, plentiful power outlets, ergonomic chairs, and effective booking systems become essential. Moreover, organizations must establish clear etiquette guidelines to prevent territorial disputes and ensure that shared spaces remain tidy. All of these considerations are easier to approach once you understand the financial context, which this calculator seeks to provide.
Another factor is employee satisfaction. Some people thrive in ever-changing environments, while others crave the stability of a personal desk adorned with family photos and ergonomic accessories. Hybrid policies might allocate dedicated desks to employees with specialized equipment while offering hot desks to mobile workers. Monitoring usage patterns over time can reveal whether the initial assumptions hold, allowing you to recalibrate the number of shared desks. The calculator simplifies that iterative process by letting you plug in new attendance figures as policies evolve.
Finally, consider the environmental impact. Reducing the number of desks and the square footage of your office lowers embodied carbon from furniture manufacturing and ongoing emissions from heating, cooling, and lighting. When combined with remote work, hot-desking can play a small but meaningful role in corporate sustainability efforts. By framing the decision in both financial and ecological terms, leaders can make informed choices that align with organizational values.
