Agent attrition cost calculator

Attrition in contact centres is rarely framed in its true cost. This calculator converts your attrition rate into a hard annual number — and shows the persistent capacity drain that makes understaffing worse than your rota suggests.

All channelsRecruitment + productivity model
iCosts are illustrative — the multipliers reflect common industry ranges for the UK/US/EU markets. Your actual recruitment cost, ramp curve, and oncost rate will produce a more precise result. The capacity drain calculation (steady-state FTE in ramp) is a planning constant regardless of the currency values.

Steady-state capacity drain

1.2FTE equivalent always in ramp

2.3% of your seated capacity is occupied by ramping agents at any given time.

What this means for staffing: you need 52 rostered agents to deliver the capacity of 50 fully productive agents — a 2.3% buffer purely from attrition churn.

Frequently asked questions

What is a typical contact centre attrition rate?

Contact centre attrition typically runs 25–40% per year in most markets, with some high-volume outbound or BPO environments exceeding 60–80%. In-house operations with stronger culture and career paths tend to sit in the 15–25% range. Anything below 15% is considered low for the industry.

What does it cost to replace a contact centre agent?

Total replacement cost typically ranges from 0.5× to 1.5× annual salary when you include recruitment fees or time, onboarding administration, training facilitator time, and the productivity gap while the new agent ramps. For a frontline agent earning £25,000/year, this often works out to £5,000–15,000 per leaver.

How does attrition affect service levels?

Beyond the direct cost, attrition creates a continuous capacity drain. Agents in ramp deliver only 50–70% of a tenured agent's productivity. At 25% attrition with a 12-week ramp, a 50-agent team is effectively running at the capacity of a 47-agent team at any given time — a persistent shortfall that must be offset by either overhiring or accepting worse service levels.

What does 'steady-state capacity drain' mean?

At a steady attrition rate, a predictable number of agents are always somewhere in their ramp period. This number can be estimated: if 25% of 50 agents (12.5) leave each year, and the ramp is 12 weeks at 60% productivity, roughly 1.7 FTE-worth of capacity is permanently consumed by the ramp gap. This is a planning constant you should add to your seated requirement.

Factor attrition into your staffing plan

Turnella lets you set an annual attrition buffer on each workstream — it adds the attrition headcount into your hiring recommendation automatically, so your plan stays accurate as your team churns.
