Calculating the cost of unused desks and rooms

Calculate unused workspace cost in two steps: identify paid capacity that went unused, then determine what spending a workable change could avoid. The first figure describes past allocation; the second supports a decision. The two need not match.

Define the unused capacity

Choose a representative period and identify what was paid for: reserved desks, a private room, prepaid meeting hours or booking credits. Compare each entitlement with use when the team needed that resource. Mark closures, holidays and unusual projects.

A desk empty on several days may still be needed for a recurring team day. A room reserved and left empty differs from one available but never booked. Before assigning a cost, check whether unused credits had a separate price or were bundled into a fee.

Define the unused capacity

Separate allocation from avoidable spending

Where each reserved desk has a separate fee, calculate:

Fee per desk for the period × paid desks consistently unused = allocated unused-desk spending.

If the fee is bundled and has no supported per-desk price, report the unused desks or desk days without inventing a unit cost. An allocation describes the existing bill; it does not establish a saving.

For rooms hired separately, add charges for unused reservations that could not be cancelled or credited under the applicable terms. For rooms included in one membership fee, do not multiply unused hours by an invented hourly rate. Compare the current total fee with a written offer for the room access the team would still need.

The prospective avoidable amount is the difference between the current commitment and a confirmed alternative that supports essential work, after any overlap or change charge and from the date a change can take effect.

Allocated unused spending versus avoidable spending

See why the figures can differ

Suppose, solely to illustrate the arithmetic, four reserved desks cost $400 each per month. If two go unused throughout a representative month, $800 of that month’s fee is allocated to them.

A workable two-desk offer of $900 a month would reduce future monthly spending by $700, provided the change could start immediately with no extra charge. If the current term cannot change for three more months, the empty desks produce no contractual saving during those months.

The example is hypothetical. In a real decision, confirm that the alternative has suitable desks on the team’s busiest recurring day and that its quoted fee and effective date apply.

Avoid double counting

Do not add an attributed share of a bundled fee to a separately calculated alternative-plan saving; both may describe the same money. Keep refundable deposits outside expenditure, and count an advance payment in the period it covers. Compare amounts on the same GST basis.

For each option, report past paid-but-unused allocation, future spending through the earliest practical change date and the difference from a workable alternative. Leave the prospective difference unresolved until price, access and effective date are confirmed.
