What Is Agent Utilisation?
Agent Utilisation measures how much of an agent's available time is spent on productive support work — a key lever for capacity planning.
Key Takeaways
- Agent utilisation is the percentage of available time spent handling customer contacts.
- Target utilisation of 70–80% balances productivity with agent wellbeing and responsiveness.
- Over 85% utilisation consistently leads to burnout and quality degradation.
- Utilisation data drives staffing decisions and shift scheduling.
What agent utilisation measures
Agent Utilisation (sometimes called occupancy rate) is the percentage of an agent's logged-in, available time that is spent actively working on customer contacts — handling tickets, on calls, in chats — versus being available but idle. If an agent is logged in for 8 hours and spends 6 hours in active contact handling (including after-call work), their utilisation is 75%. The remaining 25% is 'available but idle' time, which provides the buffer needed to answer new contacts promptly.
Why 100% utilisation is a trap
Maximum utilisation sounds desirable — every minute filled with productive work — but it creates serious operational problems. When agents have no idle time, response times deteriorate the moment volume spikes. Queues build instantly and recovery is slow. Sustained high utilisation also causes burnout: agents handling back-to-back contacts without breathing room make more errors, deliver lower-quality interactions, and leave teams at higher rates. Target utilisation of 70–80% is the operational sweet spot for most support teams — high enough to be efficient, low enough to maintain quality and responsiveness.
Using utilisation for staffing decisions
Utilisation is the foundation of support capacity planning. If average utilisation is below 60%, you are overstaffed for current volume — consider whether headcount can be reduced or redeployed. If utilisation consistently exceeds 85%, you are understaffed and quality and morale will suffer. Combine utilisation data with volume forecasts to model staffing requirements for different growth scenarios. Workforce management tools automate this modelling, but even a simple spreadsheet with volume by hour and target utilisation gives a useful first approximation.
Utilisation versus productivity
Utilisation measures time spent on contacts — it says nothing about the quality or efficiency of those contacts. An agent can be at 80% utilisation while producing poor CSAT scores or very long average handle times. Pair utilisation with CSAT, FCR, and average handle time to get a complete picture of agent performance. The combination of high utilisation, high CSAT, and low handle time is the profile of an efficient, high-quality agent worth investing in and retaining.
