UK Staff Turnover Calculator

The average UK staff turnover rate is around 35% annually, though this varies widely by sector. Hospitality and retail typically see 50–70%; professional services average 15–25%. A rate below your industry benchmark is generally considered healthy. Use our calculator above to compare your rate against your sector's average.

Turnover rate = (number of leavers ÷ average headcount) × 100. Average headcount is typically calculated as (employees at start of period + employees at end of period) ÷ 2. For an annual rate, measure over a 12-month period. For shorter periods, annualise by dividing the period rate by the number of months and multiplying by 12.

The CIPD estimates average replacement cost at 6 months' salary per leaver, covering recruitment, onboarding, lost productivity, and management time. For a £25,000/year employee, that's approximately £12,500 per leaver. High-turnover businesses can spend hundreds of thousands per year on replacement costs without realising it — the hidden costs of lost productivity and management time are often larger than the obvious recruitment fees.

The most common causes in UK SMEs are: poor scheduling (unpredictable shifts, last-minute changes), slow or unfair leave approval, lack of visibility into hours and pay, and management communication issues. Many of these are operationally addressable — they don't require pay increases or structural changes. Better systems that give staff clarity and fairness make a measurable difference.

Practical steps: give staff visibility of their schedule further in advance, approve leave requests quickly and consistently, make it easy to submit time tracking and track hours, and use an absence management system that flags problems early. TimeTally addresses all of these — time tracking in 60 seconds, one-tap leave approval, full schedule visibility for all staff, and automated absence tracking.
