What it means
Most business software is sold per seat, meaning one paid licence for each person who can use it. Seats are bought in bulk during a rollout or negotiated annually, and over time people leave, change roles or stop using the tool.
Without a regular check, the company keeps paying for licences nobody touches, and nobody notices because the invoice looks the same every month. Utilisation matters because software is now one of the largest overheads in many organisations, often growing faster than headcount.
A small gap between seats bought and seats used looks harmless on one tool, but across dozens of subscriptions it can add up to a significant annual cost. The measure needs a clear definition of active.
Some teams count anyone who logged in during the last 30 days, while others require meaningful activity, such as creating a document or running a report. The stricter the definition, the lower the utilisation, so the definition should be fixed before comparing tools.
For the customer, low utilisation is a prompt to reduce seats, renegotiate or retire the tool. For the software vendor, the same figure is an early warning of churn, because customers who barely use a product are the ones most likely to cancel at renewal.
Finance teams combine utilisation with price to calculate the cost of unused seats. This turns a vague feeling that the company has too many licences into a dollar figure that can be put in front of budget owners.
A sensible target is rarely 100%. Some spare capacity is useful for new hires and seasonal staff, so many teams treat a band such as 80% to 90% as healthy and investigate anything well below it.
In practice
Real-world examples.
Example
A marketing agency reviews its design software and finds 60 of 100 seats were active in the last month. By removing 30 seats and keeping a small buffer, it saves $9,000 a year before the next renewal.
Example
A software vendor's customer success manager sees that a large client's utilisation has fallen from 85% to 45% in two quarters. She schedules training sessions and a usage review before the renewal conversation.
Example
A hospital group's finance team compares utilisation across its scheduling, billing and messaging tools. The messaging platform shows only 38% utilisation, so the group asks the vendor to move it to a smaller plan. The vendor agrees to a lower price per seat in return for a longer contract.
Formula
Calculation
Seat utilisation = Active seats / Paid seats x 100
Cost of unused seats = (Paid seats - Active seats) x Price per seat
A company pays for 400 seats at $30 per seat per month, of which 280 are active. Utilisation = 280 / 400 = 0.70, or 70%. Unused seats = 400 - 280 = 120. The monthly cost of unused seats = 120 x 30 = $3,600, which is 3,600 x 12 = $43,200 a year.Case study
Seen in the real world.
Kestrel Logistics is an illustrative, fictional freight company that had signed up for a collaboration tool with 500 seats during a rapid expansion. Two years later the finance manager noticed the invoice had never changed even though several offices had closed.
An audit showed that only 310 of the 500 seats had been used in the last 60 days. At $25 per seat per month, the unused 190 seats were costing $4,750 each month.
The manager reduced the order to 340 seats, keeping a buffer for new staff, and set up a quarterly review. In this illustrative story, the saving of $2,000 a month paid for the work of auditing every other subscription as well. The manager also asked each department head to confirm their seat list once a quarter. Within a year, the company had cut its total software spend by a noticeable margin without removing a single tool that staff relied on.
Watch out
Common mistakes.
- Counting a seat as used because it was assigned to someone, when the person has not logged in for months.
- Aiming for 100% utilisation, which leaves no room for new joiners and can force expensive mid-term upgrades.
- Reviewing utilisation only at renewal, when it is too late to negotiate from a position of knowledge.
Questions
People also ask.
How often should seat utilisation be checked?
Quarterly is a sensible rhythm for most tools, with monthly checks for the most expensive ones.
What counts as an active user?
That is a policy choice, but a common rule is at least one meaningful action in the last 30 days.
Can low utilisation ever be acceptable?
Yes, for specialist tools that are only needed seasonally, as long as the cost is small compared with the value delivered when they are used.
