Attrition Rate

What is attrition rate?

Attrition rate is the percentage of employees who leave an organization over a specific period, typically one year.

Unlike sudden layoffs or terminations, attrition usually indicates a gradual reduction in the workforce, often because the employee chooses to leave.

Types of attrition

Several types of attrition can occur in an organization, including voluntary and involuntary attrition.

• Voluntary attrition refers to the voluntary departure of employees from an organization. This can include employees who resign, retire, or are terminated for cause. Voluntary attrition is often seen as a sign of employee dissatisfaction or a lack of job opportunities within the organization.
• Involuntary attrition refers to the involuntary loss of employees from an organization. This can include employees who are laid off, fired, or otherwise forced to leave the organization. Involuntary attrition can be caused by a variety of factors, such as a decline in business or a change in company strategy.

In addition to voluntary and involuntary attrition, other types of attrition can occur in an organization, such as natural attrition and functional attrition.

• Natural attrition refers to the normal turnover of employees that occurs as a result of retirement, resignation, or other personal reasons. This type of attrition is typically seen as a natural part of the employment cycle and does not necessarily indicate a problem within the organization.
• Functional attrition refers to the loss of employees from a specific department or function within an organization. This type of attrition can be caused by a change in business needs or a restructuring of the organization. Functional attrition can have a significant impact on the affected department and may require the organization to hire new employees or reassign existing staff.

How to lower attrition?

Attrition, or the loss of employees from an organization, can have negative impacts on productivity, morale, and the overall success of the business.

Here are a few steps that organizations can take to lower their attrition rates:

1. Identify the causes of attrition: The first step in reducing attrition is to identify the underlying causes. This could include factors such as poor job satisfaction, lack of opportunities for advancement, or a difficult work environment. By understanding the root causes of attrition, organizations can develop targeted strategies to address these issues.
2. Improve employee engagement: Employee engagement is closely tied to retention, and organizations with high levels of engagement tend to have lower attrition rates. To improve employee engagement, organizations can focus on factors such as recognition, communication, and opportunities for growth and development.
3. Offer competitive benefits and compensation: Employees who feel valued and appreciated are more likely to stay with an organization, and one way to show appreciation is through competitive benefits and remuneration. Organizations should regularly review their benefits and pay scales to ensure that they are competitive with other organizations in their industry.
4. Provide opportunities for growth and development: Employees who feel like they are learning and growing in their careers are more likely to stay with an organization. Organizations can provide opportunities for growth and development through training and development programs.
5. Develop a positive work environment: A positive work environment can have a significant impact on employee retention. Organizations should strive to create a work environment that is supportive, collaborative, and inclusive, and that promotes a sense of belonging and engagement among employees.

By taking these steps, organizations can reduce their attrition rates and improve the retention of valuable employees.

Additional hiring-focused tactics, complementary to the steps above:

• Move skills validation ahead of interviews. Screening on a standardized assessment before the interview stage removes the guesswork that produces early mis-hires.
• Run structured interviews, not conversational ones. Consistent question sets scored against a rubric reduce fit-related surprises that show up as attrition inside the first year. A full comparison of structured vs. unstructured interviews breaks down the measurable difference in outcomes.
• Fix the candidate experience, not just the offer. Candidates who go through a disorganized or opaque process arrive with lower trust and leave faster when friction shows up on the job. See what a positive candidate experience looks like in practice.
• Build internal mobility paths before employees start looking outside. LinkedIn's Talent Solutions data shows internal mobility rose 6% year-over-year, and companies that expanded internal moves saw a corresponding dip in voluntary exits among employees who would otherwise have left to advance elsewhere.
• Track attrition by tenure band monthly, not annually, so a spike in first-year exits gets caught while it is still one bad hiring quarter, not a full-year trend.

Attrition vs turnover: what’s the real difference?

Attrition and turnover rate are not interchangeable. Attrition assumes the role stays vacant; turnover assumes it gets backfilled, and mixing the two skews every retention report sent to leadership.

Most HR tech platforms, including applicant tracking dashboards, default to turnover because it is easier to pull from hiring data. If a report only labels one number “employee turnover,” check whether backfilled roles are excluded before using it to model attrition-driven headcount gaps.

Attrition vs retention: two sides of the same coin

While the attrition rate measures how many people leave, retention focuses on how many choose to stay.

• High attrition means fewer employees are staying with the company.
• High retention means your strategies are working to keep employees engaged, motivated, and committed.

Comparing attrition vs retention helps HR leaders track organizational health. A rising attrition rate might signal low employee morale, weak leadership, or a lack of growth opportunities.

Why does your attrition rate matter?

Understanding your employee attrition rate can reveal much about your workplace culture, leadership style, and long-term sustainability. It matters because:

• Cost to replace: Replacing an employee can cost up to 50:200% of their salary.
  
• Knowledge loss: When experienced employees leave, they take valuable institutional knowledge.
  
• Team disruption: High attrition can impact team morale and overall productivity.
  
• Employer branding: A poor retention reputation can hurt your chances of attracting top talent.
  
• Root cause diagnosis: Exit interviews during attrition can uncover deep-rooted issues that need attention.

How to calculate the attrition rate?

Here’s the simple formula to calculate the employee attrition rate:

Attrition Rate (%) = (Number of employee exits during a period ÷ Average number of employees during that period) × 100

Let’s break it down with an example:

• Suppose 12 employees left during the year.
• The average headcount throughout the year was 150.
  

Your attrition rate would be:

(12 ÷ 150) × 100 = 8%

Note: This calculation only includes voluntary separations where the employee chooses to leave, not layoffs or internal transfers.

So, if you’re wondering how to calculate attrition rate, the answer lies in regularly using this simple yet powerful formula and tracking it over time.

Worked example (monthly cadence): a company starts the year with 480 employees and ends with 520, for an average headcount of 500. If 50 employees left during the year and none of those roles were backfilled, attrition rate = (50 / 500) x 100 = 10%. Run the same calculation monthly (for example, 12 exits against an average headcount of 240 in a smaller team) and you get 5% for that month.

Pro Tip: Calculate attrition monthly and roll it into a trailing 12-month average. A single bad month (a reorg, a seasonal spike) will distort an annual figure calculated only once a year, and you will not catch the trend until it is already a retention crisis.

What is considered a ‘high’ employee attrition rate?

There’s no one-size-fits-all benchmark, but generally:

• An attrition rate above 15% is considered high across most industries.
  
• In high-growth sectors like tech or retail, up to 20% may be tolerable.
  
• Even 10:12% can be concerning in stable industries like healthcare or finance.
  

What is considered a ‘high’ employee attrition rate also depends on company size, job function, and geographic location. If you see a rise year-over-year, that’s a sign to dig deeper.

National labor data gives a defensible floor for comparison:

Treat the ~22% annualized quits figure as a national floor, not a target. A company running meaningfully above it, especially concentrated in the first year of tenure, is very likely looking at a hiring-fit problem rather than a market-driven one. A company running well below it may be retaining people who should have moved on, which shows up later as disengagement rather than attrition.

What Causes Employee Attrition?

Attrition has structural causes (retirements, restructuring, planned role elimination) and behavioral causes (voluntary exits driven by fit, management, or growth). The behavioral segment is the one most within HR's control, and it clusters around a small number of drivers.

• Poor role fit at hire: the employee's actual skills or working style did not match what the role required, a mismatch that structured pre-hire assessment is built to catch.
• Manager relationship quality: research from Harvard Business Review's Ethan Bernstein and Michael Horn identifies manager and colleague relationships, alongside career advancement opportunity, as the core “push and pull” forces behind voluntary exits, ahead of compensation alone.
• Lack of internal mobility: LinkedIn's Talent Solutions data shows internal mobility rose 6% year-over-year, and companies that expanded internal moves saw a corresponding dip in voluntary exits among employees who would otherwise have left to advance elsewhere.
• Compensation and workload misalignment: pay or hours that fall out of step with market rate or role scope, typically surfaced in exit interviews within the first 90 days.
• Unclear growth path: employees who cannot see a next role inside the company look for one outside it.

How Does Hiring Quality Affect Attrition?

Most regrettable attrition is decided before an offer letter goes out, not after. When a hire is made on interview charisma or resume keywords rather than validated skills and role fit, the mismatch surfaces inside the first year, exactly the segment of attrition that is most preventable and most expensive to absorb repeatedly.

Testlify built its Fit-First Hiring Framework around that gap. Instead of screening resumes first and validating skills later in the process, Fit-First moves a standardized skills and role-fit assessment ahead of the interview, so hiring managers are choosing between candidates who have already cleared a fit bar, not choosing based on interview performance alone. The framework runs on three checkpoints:

• Validated skills signal: a role-specific assessment, drawn from Testlify's library of 3,500+ tests, replaces self-reported experience with a scored, comparable result.
• Role and culture fit signal: a structured fit check run before the interview stage, so interviewers are confirming fit rather than guessing at it.
• Early-tenure feedback loop: attrition and performance data from the first 12 months are fed back into the assessment criteria, so the fit bar improves with every hiring cycle instead of staying static.

Enterprise teams running structured, skills-first hiring through Testlify report a 55% reduction in time to hire and 94% candidate satisfaction with the process, both of which correlate with lower early-tenure attrition because candidates who go through a clear, fair, well-signaled process are less likely to accept an offer that turns out to be a poor fit for either side. For a deeper look at the mechanics, see how skills-based hiring is changing pre-hire screening, and how skill assessments during the hiring process build higher-performing teams from the first round.

Attrition data only becomes useful once you can see which segment of it is fit-driven. Testlify's skills and role-fit assessments plug in before the interview stage, so hiring teams stop finding out about a bad fit eight months into the role.
