A small startup or an established enterprise losing its employees isn’t just an HR challenge: it’s a business risk. Hence understanding employee attrition, measuring the attrition rate, recognizing early signs, and acting decisively can help reduce the exits. And build a stronger, more committed workforce. This article takes you through each step– from meaning to measurement, from analysis to action – in simple language and clear examples. Let’s begin.
What is Attrition?
Attrition refers to a continuous decrease in the size of the workforce when employees leave and their roles remain unfilled for a period. It is often characterised by natural exits (resignations, retirements, relocations) rather than forced exits like mass layoffs.
For example: If an organisation has 150 employees, and 10 employees resign during a year that are not replaced immediately, the workforce shrinks and you have experienced attrition.
At manageable levels, this may be intentional (cost-optimisation, restructuring). Yet, when uncontrolled, high attrition signals deeper issues.
What is Employee Attrition?
Employee attrition is the term used when employees permanently leave your organisation and the roles may not be immediately filled. It’s a metric of change in workforce stability rather than just movement.
When this happens repeatedly or across key teams, your organisation may lose momentum, institutional memory and critical skills.
For example, an experienced software developer leaves in an IT startup and the company delays hiring a replacement – over time, that gap may slow product delivery, burden remaining team members and eventually lead to further churn.
What is Employee Attrition Rate?
The Employee attrition rate is a key metric: it tells you how many employees leave your organisation over a defined period compared to the average workforce size during that period.
Attrition Rate Definition
The percentage of employees leaving your organisation over a given period (voluntary or involuntary), relative to the average headcount in that period.
Attrition Formula
Attrition Rate Formula= (Number of employees who left ÷ Average number of employees) × 100
Example
Suppose at the start of the year you had 200 employees, at the end you have 190, and during the year 20 employees left.
Average employees = (200 + 190) ÷ 2 = 195
Attrition rate = (20 ÷ 195) × 100 = 10.26%
Tracking this gives you visibility on workforce stability and helps compare across years, departments or industries.
Employee Attrition vs. Employee Turnover
These terms are often used interchangeably but they differ:
- Employee attrition = when employees leave and aren’t immediately replaced → workforce shrinks.
- Employee turnover = when employees leave and are replaced → workforce remains stable in size, but there is churn.
Here’s a comparison:
Basis | Employee Attrition | Employee Turnover |
What it shows | Net reduction in workforce size | All exits and replacements |
Workforce impact | Fewer people over time | Same number or stable headcount |
Example | Retirement of senior staff and role left open | Resignation and quick hire to fill the spot |
Strategic focus | Long-term stability, cost control | Hiring velocity, short-term staffing health |
Understanding this distinction is important so you can choose the right metric and focus your retention strategy appropriately.
Types of Employee Attrition
It comes in different flavours. Here are key types you should recognise:
- Voluntary Attrition – Employees choose to leave (better offers, dissatisfaction, relocation).
- Involuntary Attrition – Company initiates exit (termination, restructuring).
- Retirement – Employees retire and the role may remain vacant or is removed.
- Internal Attrition – Employees move to different roles or departments internally; the original role may stay vacant.
- Demographic – When certain groups (by age, gender, skill level, tenure) leave at higher rates, signalling structural issues.
- Functional vs Dysfunctional Attrition – Functional: people whose departure has low impact. Dysfunctional: key talent leaving, very negative.
Recognising the types helps you tailor your response: losing critical talent requires different action than a routine retirement exit.
Is Employee Attrition Always Bad?
Not necessarily. The question is why and how fast employees are leaving.
When Attrition Can Be Healthy
- You are removing redundant roles or outdated positions deliberately.
- Your workforce is evolving and you are hiring new talent in place of old.
- Strategic restructuring leads to better fit between roles and business needs.
When Attrition Becomes Harmful
- High performing employees frequently resign.
- You experience exit rates above industry norms or escalate suddenly.
- Knowledge drain, client disruption, or morale drops follow.
- Remaining employees face increased workload and burnout.
Reasons for Employee Attrition and Leading Indicators
To reduce attrition, you first need to understand the reasons and watch the early warning signs.
Reasons for Employee Attrition
Here are key drivers:
- Lack of career growth or internal mobility – Employees feel stuck.
- Compensation-mismatch or non-competitive pay – They find better offers.
- Poor leadership or management quality – Bad managers drive talent away.
- Work-life imbalance, burnout – Excessive hours, no flexibility.
- Weak workplace culture or recognition – When employees feel undervalued.
- Lack of learning opportunities – Particularly for younger workforce.
- Cultural or demographic mismatch – When groups feel excluded or unsupported.
Leading Indicators / Early Warning Signs
These are metrics or signals that suggest the risk is rising:
- Engagement/pulse survey scores dropping or participation falling.
- Increase in absenteeism, sick leaves or overtime hours.
- Employees staying long in the same role with no promotion.
- Manager feedback ratings dipping or number of complaints rising.
- New hire exits within first 30-90 days (early churn rate).
- Pay raise or bonus delays, or large number of unused leaves.
By monitoring these, you can intervene before exit levels spike.
How to Calculate the Attrition Rate
Here’s a step-by-step guide:
1. Count the number of employees who left during the period (resignations, retirements, terminations if you include).
2. Calculate the average headcount during that period.
- Simple method: (Headcount at start + Headcount at end) ÷ 2
- For more accuracy (especially in growing organisations): arithmetic mean of monthly headcounts.
3. Apply the formula:
Attrition Rate = (Employees who left ÷ Average employees) × 100
Example:
- Start of year: 120 employees
- End of year: 100 employees
- Employees who left during year: 30
- Average headcount = (120 + 100) ÷ 2 = 110
- AR = (30 ÷ 110) × 100 = 27.3%
A rate this high should prompt immediate review of retention policies.
Remember: always define clearly what counts as a “leaver” (resignation, termination, transfer, retirement) to ensure consistency.
Employee Attrition Analysis
Measuring the attrition rate is just the first step towards developing employee retention. The real value comes when you analyse it. Therefore, it’s crucial to drill down into which teams, which tenures, which managers are experiencing higher employee loss and why.
Here’s how to do it:
- Define your counting policy and timeframe (who is a leaver, what constitutes attrition).
- Compute both overall and early attrition (0-90 days) to check onboarding or early fit issues.
- Segment the data — for example by tenure, department, location, manager, role level.
- Overlay leading indicators — engagement scores, manager ratings, promotion velocity, overtime, pay percentile.
- Prioritise root causes and set targets — pick 2-3 key drivers, set a realistic attrition reduction target (e.g., reduce early attrition to <10% in next 6 months).
Also, visualising attrition trends (monthly/quarterly) helps spot unusual spikes and track whether interventions are working.
Actionable Tips for Attrition Management
Here are seven practical, specific steps you can take now to reduce attrition:
- Implement quarterly stay-interviews: Ask top performers why they stay, what might make them leave; act on 1-2 insights immediately.
- Publish clear career maps for each role: Show employees how they can progress (role → senior role → lead → manager) and what training/skills are needed.
- Use real-time recognition tools: Set up a peer-to-peer digital ‘kudos’ system; track monthly recognition counts and tie them to rewards.
- Benchmark compensation every six months: Create a market-pay matrix for your region/industry; adjust pay for top 20% talent and critical roles.
- Train managers in leadership & feedback: Run a 4-week “manager effectiveness” programme focusing on communication, coaching, and retention mindset.
- Offer flexible work options and monitor overtime: Allow hybrid or remote work; track overtime hours per employee – if someone logs >45 hrs/week consistently, schedule a workload review.
- Deploy engagement / pulse dashboards: Send monthly 3-question pulse survey (e.g., “I’m clear about my role”, “I feel valued”, “I intend to stay 12 months”). If score drops below set threshold, trigger one-on-one with manager and HR.
These action-oriented tips help you not just react to attrition, but build proactive retention culture.
How HRMS Tools Can Help
Modern HRMS platforms are vital in tracking, analysing and acting on attrition data. Here’s what a good HRMS should offer, especially dashboards & reports:
1. Dashboards:
Real-time visibility of overall attrition rate, early churns, team-wise attrition levels, high-risk managers, and trending heat-maps.
2. Reports:
Custom reports showing attritions by tenure, department, manager, reason for exit, and comparison to industry benchmarks.
3. Analytics & visualisations:
Cohort survival curves (new-hire retention over first 90 days), pop-up alerts when attrition crosses thresholds, predictive risk scores for upcoming exits.
4. Automated surveys & feedback:
Built-in pulse survey tools to gather engagement/manager feedback, aggregated on dashboards.
5. Exit & stay interview workflows:
Exit interviews are a digitized process to capture why people leave and why they stay, feeding data into attrition dashboards.
6. Leader-specific views:
Managers see their own team’s attrition risk, HR sees organisational overview.
With these tools your HR team can move from spreadsheets to actionable insight, spotting attrition risks early and intervening effectively.

FAQ (Frequently Asked Questions)
What is employee attrition?
Employee attrition means the gradual loss of employees over time when they leave an organization and their positions are not immediately replaced. It shows how the workforce size reduces naturally through resignations, retirements, or other exits.
Is 20% attrition high?
Yes, 20% attrition is considered high for most industries. A healthy attrition rate usually ranges between 10% to 15%, depending on the sector. Anything above 20% signals potential retention issues.
What is attrition vs turnover?
Attrition occurs when employees leave and their roles remain unfilled, leading to a smaller workforce. Turnover happens when employees leave but are replaced, keeping the overall headcount stable.
What does 90% attrition mean?
A 90% attrition rate means that 90 out of every 100 employees left the organization during a certain period. It indicates an extremely unstable workforce and serious retention challenges.
How to prevent employee attrition?
To prevent attrition, focus on improving work culture, offering career growth, providing competitive pay, recognizing employee efforts, and maintaining open communication through regular feedback.
Which job has the highest attrition rate?
Industries like BPO, retail, hospitality, and IT services often face the highest attrition rates due to long working hours, high stress, and limited growth opportunities.
