What is Attrition Rate?
Attrition rate (also called employee turnover rate) measures the percentage of employees who leave an organization during a given period. It is one of the most important HR metrics for understanding workforce stability, hiring needs, and the overall health of an organization.
High attrition rates indicate potential issues with employee satisfaction, compensation, management, or workplace culture. Tracking attrition helps HR teams identify patterns, plan recruitment budgets, and take corrective action before turnover becomes a problem.
Attrition rate is calculated as separations divided by average headcount, multiplied by 100
The average attrition rate across Indian industries is 18-22% annually
Attrition includes voluntary resignations, terminations, retirements, and all other separations
Track Employee Retention with Attendo
Attendo maintains complete employee records from joining to exit. Track attrition trends, generate headcount reports, and identify retention risks across branches.
Healthcare: 15-20% annually (moderate, varies by role and location)
Startups: 25-40% annually (high growth phases, role uncertainty)
If your attrition rate is significantly above your industry benchmark, it may be worth reviewing compensation, work culture, growth opportunities, and management practices.

FAQ
Frequently Asked Questions
Common questions about attrition rate calculation.
What is the formula for attrition rate? +
Attrition Rate = (Number of Separations / Average Headcount) x 100. Average headcount is calculated as (Start headcount + End headcount) / 2.
What is the difference between attrition and turnover? +
In most HR contexts, attrition and turnover are used interchangeably. Technically, attrition sometimes refers to positions that are not refilled after an employee leaves, while turnover includes all separations regardless of replacement. This calculator treats them the same.
What is a good attrition rate? +
It varies by industry. Generally, 10-15% annually is considered healthy. IT companies average 20-25%, BPOs 30-40%, and manufacturing 10-15%. Compare your rate against your specific industry benchmark.
How do you annualize a monthly attrition rate? +
Multiply the monthly attrition rate by 12. For example, if monthly attrition is 2%, the annualized rate is 24%. This is an approximation that assumes a constant rate throughout the year.
Should I include involuntary terminations in attrition? +
Yes, the standard attrition rate includes all separations: voluntary resignations, involuntary terminations, retirements, and any other exits. For deeper analysis, calculate voluntary and involuntary attrition separately.
What is retention rate? +
Retention rate is the inverse of attrition: Retention Rate = 100% - Attrition Rate. If your attrition rate is 15%, your retention rate is 85%, meaning 85% of employees stayed during the period.
How does attrition affect business costs? +
Replacing an employee costs 50-200% of their annual salary, including recruitment, onboarding, training, and lost productivity. For a company with 100 employees and 20% attrition, that could mean replacing 20 people per year at significant cost.
How often should attrition be measured? +
Most companies track attrition monthly and report it quarterly and annually. Monthly tracking helps catch sudden spikes early. Annual rates provide the big picture for strategic planning and benchmarking.
