Calculate your employee turnover rate and compare against UK benchmarks. Understand the cost of attrition.
Employee turnover rate is calculated by dividing the number of leavers by average headcount and multiplying by 100. The UK average annual turnover is approximately 15% according to CIPD research, though this varies significantly by sector.

What is Staff Turnover Rate?
Staff turnover rate measures the percentage of employees who leave an organisation during a given period. It is one of the most important HR metrics because high turnover directly impacts productivity, team morale, and the bottom line.
Turnover can be voluntary (resignations, retirements) or involuntary (dismissals, redundancies). Tracking both separately helps you understand whether employees are choosing to leave or being asked to leave, which requires different interventions.
According to CIPD research, the average UK employee turnover rate is approximately 15% per year. However, this varies dramatically by sector — hospitality sees rates above 30%, while public sector organisations typically see below 10%.
The Turnover Rate Formula
UK Turnover Benchmarks by Sector
| Sector | Avg Annual Turnover | Notes |
|---|---|---|
| Hospitality & Leisure | 30%+ | Seasonal and shift-based roles drive higher turnover |
| Retail | 25-30% | Part-time and student workers contribute to high rates |
| Technology | 15-20% | Competitive market with high voluntary turnover |
| Professional Services | 12-15% | Varies by seniority; graduate schemes have higher churn |
| Manufacturing | 10-15% | Stable sector with longer average tenure |
| Healthcare (NHS) | 12-14% | Vacancy rates remain high in nursing roles |
| Education | 8-12% | Academic year cycle affects timing of departures |
| Public Administration | 6-10% | Pension benefits support retention |

What is the cost of high turnover?
According to CIPD and Oxford Economics research, the average cost to replace an employee in the UK is approximately £30,000, factoring in recruitment, onboarding, lost productivity, and the learning curve for the replacement. For senior or specialist roles, this figure can exceed £50,000.
The costs break down into several categories:
Recruitment costs
Job advertising, agency fees, interview time, background checks
Onboarding costs
Training, IT setup, HR admin, buddy/mentor time
Lost productivity
New hires take 6-12 months to reach full productivity
Knowledge loss
Institutional knowledge and client relationships leave with the person
How can you reduce staff turnover?
Reducing turnover requires understanding why people leave. Exit interviews, engagement surveys, and stay interviews are the best tools for identifying root causes.
- Competitive pay and benefits: Benchmark salaries against market rates regularly. Consider total reward, not just base salary.
- Career development: Provide clear progression paths, training budgets, and internal mobility opportunities.
- Strong onboarding: A structured onboarding programme in the first 90 days significantly reduces early attrition.
- Flexible working: Hybrid and flexible arrangements are now expected, not a perk. Rigidity drives talent away.
- Manager quality: People leave managers, not companies. Invest in management training and feedback loops.
- Recognition and purpose: Regular recognition and connection to company mission improve retention.
Frequently Asked Questions
What is a healthy staff turnover rate?
A healthy staff turnover rate is generally considered to be between 10% and 15% annually, though this varies significantly by industry. Hospitality and retail typically see rates of 20–30% or higher, while public sector and professional services tend to be lower at 8–15%. The key is to benchmark against your specific sector and track trends over time rather than fixating on a single number.
How do you calculate monthly turnover rate?
Monthly turnover rate is calculated by dividing the number of employees who left during the month by the average headcount for that month, then multiplying by 100. The formula is: Monthly Turnover Rate = (Number of Leavers / Average Headcount) × 100. To annualise a monthly rate, multiply by 12. For example, if 3 people left from an average headcount of 100, the monthly rate is 3% and the annualised rate is 36%.
What is the average UK employee turnover rate?
According to CIPD research, the average UK employee turnover rate is approximately 15% per year, though this has fluctuated between 12% and 20% in recent years. Voluntary turnover (resignations) makes up the majority. Sector variation is significant: hospitality sees rates above 30%, while education and public administration are typically below 10%.
How much does employee turnover cost?
The cost of replacing an employee in the UK is estimated at 6 to 9 months of their salary, according to CIPD and Oxford Economics research. For an employee earning £30,000, this means a replacement cost of £15,000 to £22,500. Costs include recruitment advertising, agency fees, interview time, onboarding and training, reduced productivity during the learning curve, and lost institutional knowledge.
What causes high staff turnover?
The most common causes of high staff turnover in the UK include inadequate pay and benefits, lack of career development opportunities, poor management or toxic work culture, limited flexible working options, feeling undervalued or unrecognised, excessive workload or burnout, and better opportunities elsewhere. Exit interviews and employee engagement surveys can help identify the specific drivers in your organisation.
