Definition

Retention refers to the set of strategies and practices implemented to keep employees in the organisation and reduce voluntary turnover. It encompasses working conditions, pay, career prospects, company culture and management quality.

How to calculate your retention rate

Formula: Retention rate (%) = (End of period headcount − New recruits) / Start of period headcount × 100

Example: 100 employees on 1 January, 8 departures, 12 new recruits → retention rate = (104−12)/100 × 100 = 92%

A healthy rate typically sits between 85% and 95% depending on sector. Segment this calculation by tenure, department and profile to identify at-risk populations.

Effective retention strategies by phase

Before day 1

Recruitment phase

Recruit culturally aligned candidates. Provide realistic job preview (no broken promises). Quality recruitment is the foundation of retention.

Weeks 1–12

Onboarding (0–3 months)

Structured integration with mentor. Weekly check-ins first month. Clear objectives from day one. Good onboarding cuts early turnover by 30–50 %.

Months 3–12

Development (3–12 months)

Clear career path with milestones. Regular training and certifications. Constructive feedback and recognition of contributions.

After 12 months

Long-term retention

Facilitate internal moves, regular 1-to-1s with manager, engagement surveys, personalised development plans. Celebrate milestones.

Ongoing

Warning signs and prevention

Regular stay interviews to identify risk factors early. Monitor engagement indicators and take swift corrective action.

Stay interviews: an underused tool

Unlike exit interviews (too late), stay interviews involve regularly asking employees: 'What makes you want to stay? What could make you leave?' This allows you to act before departures and shows you value their perspective.

Frequently asked questions about retention

What's the average retention rate in the UK?
Retention rates vary significantly by sector: 90–95 % in public sector and finance/insurance, 80–88 % in manufacturing and B2B services, 70–80 % in retail and distribution, 60–75 % in hospitality. For an SME, a global retention rate of 88–92 % is generally satisfactory. Most important is comparing to your own sector.
How do you identify employees at risk of departure?
Early warning signs include reduced meeting participation, fewer social interactions, decreased long-term project involvement, questions about training or career development, and repeated LinkedIn profile browsing in your sector. Engagement tools (regular surveys, structured 1-to-1s) help detect these signals before resignation.
Should you make counter-offers to departing employees?
Counter-offers are risky. Studies show 80 % of employees accepting a counter-offer still leave within 12 months. Resignation usually signals deeper dissatisfaction that salary alone won't resolve. If you make a counter-offer, pair it with action plans addressing the real departure causes (management, career progression, working conditions).
How do you measure ROI on retention initiatives?
Calculate replacement cost (recruitment + training + lost productivity = 150–200 % annual salary) and multiply by avoided departures. Compare to retention programme costs (training, benefits, pay increases). A good retention programme typically delivers 3:1 to 5:1 ROI over 2–3 years.
What retention actions work best for SMEs?
For resource-constrained SMEs, highest-impact actions are: management quality (train managers in feedback and recognition — most cost-effective), formalised annual career conversations, work flexibility (partial remote, flexible hours) and transparency on strategy and prospects. Daily recognition, though non-financial, has very high impact for minimal cost.
