The True Cost of an Empty Desk: The Calculation No CFO Asks For, But Should

In the spring of 2021, HSBC announced something no major bank had ever said so plainly: it would cut its global office footprint by 40%. Not because of a business crisis – profits had fallen, but the bank remained solidly capitalized – but because the desks, quite simply, were no longer being used. The final figure, disclosed over the following years, came to nearly 800,000 square meters of abandoned space worldwide: the equivalent of 112 football pitches. In London, the bank began weighing an exit from its iconic Canary Wharf tower, the skyscraper that had been the very symbol of its headquarters for two decades, in favor of an office less than half the size.

This did not happen because someone at HSBC suddenly discovered hybrid working. It happened because someone, for the first time, looked at the badge data, the occupancy numbers, and ran a calculation that most companies never actually run: how much does an unused desk cost, every single day?

The Number No One Asks For at Budget Time

When discussing the facility management budget, the typical question is “how much does the rent cost” or “how much does energy cost.” Almost never does anyone ask: what is our real desk utilization rate? Yet that is the figure that explains everything else. According to CBRE’s Global Workplace & Occupancy Insights report, global average office utilization climbed to 53-54% in 2025, a sharp rise from 38% in 2024, but still below the 65% threshold most organizations set as an internal target. JLL’s Global Occupancy Planning Benchmark, drawn from 99 organizations managing a combined 745 million square feet, finds a similar figure: 56%.

The average, though, hides the more uncomfortable part of the story. In CBRE’s 2025 Occupier Sentiment survey, 66% of organizations report utilization below 60% on a typical day, while 73% confirm that on peak days, Tuesday through Thursday, offices are effectively full. On Mondays, global attendance drops to an average of 46%; on Fridays, to 35%. The desk stays the same, the rent stays the same: what changes is only how many of the five days it is actually paid for get used.

What an Empty Desk Actually Costs, in Hard Numbers

This is where the calculation stops being a workplace-strategy problem and becomes a finance problem. The cost of a desk is not just its share of rent: it includes fit-out, averaging $1,950 per square meter according to JLL’s Global Office Fit-Out Cost Guide, utilities, cleaning, security, and facility management – all fixed costs that stay identical regardless of how many people actually sit down. If a desk is occupied 50% of the time it is being paid for, half of that fixed cost produces nothing: no productivity, no collaboration, no presence. It is capital locked into an empty chair.

Global Workplace Analytics estimates that a company can save an average of $11,000 a year for every employee who works remotely half the time, once all real costs are properly accounted for; IWG puts the figure even higher, at $14,300 per employee, including utilities. Across a 500-person organization, the gap between these two estimates is worth between $5.5 million and over $7 million a year – a number that rarely shows up on a CFO’s slide, because it is scattered across dozens of different expense lines instead of appearing as one.

Why No One Runs This Number First

The reason this calculation almost always stays implicit is not technical, it is organizational. The cost of an empty desk never shows up as a single line item on a budget: it is spread across the lease, utilities, the IT budget, and the HR budget. None of the people who own these line items has, on their own, the complete picture – and traditional badge systems, where they exist, often only log who entered the building, not whether or for how long they actually occupied a workstation. Kastle Systems, which tracks badge-in access across ten major U.S. cities, publishes a weekly average occupancy rate that remains one of the most cited figures in the industry precisely because it is one of the few sources making visible, city by city, how far real usage lags behind contracted capacity.

The Calculation That Turned HSBC Into a Textbook Case

Back to HSBC: what made the case notable was not the size of the cut itself, but the fact that the decision was driven by real utilization data, not a hunch. The bank had observed that during the pandemic, up to 70% of its 226,000 employees worldwide worked remotely at certain points, and that even after the return to office, most buildings housing support functions and head-office activity never filled back up. The cut did not touch customer-facing branches, where physical presence carries direct value – it targeted exactly the offices where a desk had become a fixed cost with no daily return. In 2021 alone the bank freed up more than 3.4 million square feet – about 18% of its global portfolio – as the first step of a plan that would eventually reach 40%.

The lesson finance teams should take from this case is not “cut office space by 40%”: it is that the cut was only possible because someone had made visible, in numbers, the gap between space paid for and space used. JLL notes that Fortune 500 companies that pursue genuine consolidation – not simply letting people work from home while keeping the same square footage – achieve portfolio cost reductions of over a million dollars a year; CBRE estimates a range of 10% to 50% in space-cost savings for organizations that tackle the problem with real utilization data, compared with those that simply observe the trend without acting on it.

The Calculation Belongs Before Lease Renewal, Not After

The moment this calculation delivers real value is not once the problem is already obvious, but before the lease expires, while there is still room to negotiate. Organizations that collect occupancy data continuously – not a one-off headcount, but a steady stream of real attendance by time slot and day of the week – arrive at the lease-renewal table knowing exactly what percentage of their floor space they are paying for without using. Those that do not only discover the problem once the broker presents the new rent, and by then the only lever left is to accept it or move.

The question every CFO should ask before signing the next renewal is not “how much does this space cost,” but “how much of this space are we actually occupying, day by day” – because it was that second question, not the first, that let a bank headquartered in one of Europe’s most photographed skyscrapers decide to leave.
