Quick Summary
Employee retention rate at a glance
Employee retention rate measures the percentage of employees who remain with an organization during a defined period. The basic calculation compares the number of employees who stayed through the period with the number employed at the beginning.
Employee Retention Rate = (Employees remaining at the end of the period ÷ Employees at the beginning of the period) × 100
For example, if a company starts the year with 100 employees and 88 are still with the company at year-end, its employee retention rate is 88%.
Tracking the percentage is only the first step. Organizations can gain much more value by comparing retention trends with performance reviews, employee engagement, manager feedback, goals, workload, productivity, and project results.
The Basics
What is employee retention rate?
Employee retention rate is the percentage of employees who remain employed by a company throughout a selected measurement period. Organizations commonly calculate retention monthly, quarterly, or annually depending on their workforce size and HR reporting requirements.
The metric helps management understand workforce stability. A consistent retention rate can indicate that employees find enough value, direction, development, or satisfaction in their roles to stay with the organization. A declining rate may signal issues involving management, workload, compensation, career development, job clarity, workplace culture, or employee engagement.
Retention should not be viewed only as a measure of how many employees leave. It can also provide valuable context about the overall employee experience when combined with performance information.
For example, a department with strong performance results but declining retention may have workload or management problems not immediately visible through productivity numbers alone. Similarly, a department with strong retention but declining performance may need clearer goals, better training, or more frequent feedback.
The Formula
How do you calculate employee retention rate?
The most common employee retention rate formula is:
Employee Retention Rate = (Number of employees who remained throughout the period ÷ Number of employees at the beginning of the period) × 100
Suppose your company had 150 employees at the beginning of the year. During the year, 18 of those employees left. This means 132 original employees remained. The calculation would be 132 ÷ 150 × 100 = 88%, so your annual employee retention rate would be 88%.
New employees hired during the measurement period are normally excluded from this calculation because the objective is to determine how many employees from the original workforce stayed throughout the entire period.
Two Metrics
Retention rate vs. employee turnover rate
Employee retention and employee turnover are related, but they measure different aspects of workforce movement.
| Retention rate Retention measures how many employees remain with an organization. It shows workforce stability. | Turnover rate Turnover focuses on how many employees leave during a particular period. Turnover analysis can help identify when, where, and potentially why employees leave. |
A company could therefore monitor both numbers simultaneously. Retention shows workforce stability, while turnover analysis can help identify when, where, and potentially why employees leave.
Don’t interpret either metric without context. A certain amount of employee movement is normal for most organizations. What matters more is whether valuable employees leave unexpectedly, whether turnover is concentrated in specific departments, and whether recurring patterns connect to performance, management, workload, engagement, or career development.
Why It Matters
Why is employee retention important?
Employee retention affects much more than HR administration. Employee departures can disrupt projects, reduce institutional knowledge, increase recruitment costs, add workload for remaining employees, and delay business objectives.
When experienced employees remain with a company, teams can generally maintain greater continuity. Managers spend less time repeatedly onboarding replacements and can focus more on employee development, performance improvement, and strategic priorities.
Retention can also influence customer relationships. Employees who understand customers, internal processes, products, and projects often carry knowledge that new hires take time to develop.
For project-driven organizations, workforce stability can also influence delivery schedules and financial performance. When key team members leave mid-project, organizations may face additional training costs, resource changes, delays, and unplanned hours. This is where connecting workforce information with project profitability analysis becomes particularly valuable.
Performance Reviews
How performance reviews can help improve retention
Traditional annual performance reviews often identify employee concerns too late. Employees may spend months with unclear expectations, limited recognition, unrealistic workloads, or insufficient development opportunities before management notices the issue.
Modern performance review software lets managers collect feedback more often and track employee progress throughout the year.
Regular evaluations create opportunities to discuss expectations, achievements, development areas, career goals, workloads, and challenges before problems become serious.
Employees also gain greater clarity about what is expected from them. When employees understand their responsibilities and can see how their work contributes to broader organizational goals, performance conversations become more meaningful.
Performance reviews should therefore be viewed not simply as scoring exercises but as an ongoing communication process that can support employee retention.
Spotting Risk
Using performance evaluation software to identify retention risks
Performance information becomes especially valuable when you can review it over time.
With performance evaluation software, organizations can monitor KPIs, feedback, goals, evaluation trends, employee engagement, and performance changes from one system. Managers may notice situations where employee performance is declining gradually, goals repeatedly remain incomplete, or feedback indicates reduced engagement.
These signals do not automatically mean an employee intends to leave. However, they can help managers identify situations that deserve attention. An early conversation may reveal that an employee needs additional training, more realistic targets, greater recognition, clearer responsibilities, or opportunities to take on different work.
Systems such as AssessTEAM help organizations maintain continuous visibility into employee performance rather than relying entirely on occasional review meetings. Managers can use ongoing evaluations, goals, KPIs, and feedback to understand performance trends and provide support when it is most useful.
Employee Goals
Connect retention with employee goals
Employees are more likely to understand their contribution when their personal goals clearly connect to team and organizational objectives.
Goal setting creates structure around expectations and gives managers a measurable way to discuss progress. Instead of telling an employee simply to improve performance, managers can define specific objectives, milestones, and measurable outcomes.
Regular goal discussions can also reveal when employees have outgrown their current responsibilities or want more opportunities for professional development.
AI-driven goal-setting tools can further simplify this process by helping managers develop relevant goals based on job responsibilities, performance priorities, and organizational objectives.
Clearer goals can improve accountability while also helping employees understand how they can progress within the business.
KPIs & Clarity
Use KPIs to improve job clarity
Employees often become frustrated when they do not know how their performance is being measured.
Well-defined KPIs create measurable expectations around job responsibilities. Instead of relying on subjective judgments at the end of a review cycle, employees and managers can discuss performance using agreed-upon indicators.
For example, customer service employees may be evaluated using customer satisfaction, response times, resolution quality, or service consistency. Project employees may be evaluated using delivery accuracy, productivity, quality, profitability contribution, and deadline performance.
Performance management platforms with preconfigured KPI libraries can make it easier for organizations to establish relevant measures without building every evaluation process from scratch.
The objective should not be to measure everything employees do. Instead, organizations should focus on the performance indicators that best represent success in each role.
Profitability & People
Why project profitability analysis matters for retention
Employee retention and project profitability may seem like separate business concerns, but they can influence each other considerably.
Imagine a project team consistently working additional hours to deliver projects that regularly exceed their budgets. Financial reports may show shrinking project margins, while employee data may reveal increasing workload or declining engagement.
Looking only at project financials could lead management to conclude that the team needs to work more efficiently. Looking only at employee performance could miss the possibility that budgets, staffing, timelines, or project expectations are unrealistic.
Combining employee performance information with project profitability analysis gives managers a broader view. Organizations can examine whether high workloads affect employee engagement, whether resource allocation contributes to project overruns, and whether certain teams repeatedly face both profitability pressure and employee turnover.
This type of analysis can help managers make decisions that support both business performance and employee sustainability.
Segment The Data
Measure retention by department and manager
A company-wide retention rate provides a useful benchmark, but it can hide major differences between teams.
For example, an organization may maintain an overall retention rate of 90%, while one department retains 97% of employees and another retains only 72%.
Segmenting retention data can help reveal where management should investigate further. Organizations can compare retention across:
Departments and teams
Managers
Locations
Job roles
Employee tenure
Project teams
Combine these comparisons with qualitative information such as employee feedback and performance discussions. Numbers can reveal where something is happening, while conversations often help explain why.
How Often
How often should you calculate employee retention rate?
Annual retention remains useful for long-term reporting, but many organizations benefit from reviewing retention quarterly or monthly. More frequent tracking makes it easier to detect changes, rather than discovering a problem at year-end.
Large organizations may calculate retention every month because their employee population generates enough data to reveal meaningful patterns. Smaller organizations may find quarterly analysis more practical because individual departures can have a greater impact on monthly percentages.
The most important factor is consistency. Organizations should use the same calculation method and measurement periods so they can compare trends accurately over time.
Improve Retention
How to improve employee retention
Improving retention usually requires addressing why employees disengage, not just the final resignation.
Clear job expectations, regular communication, meaningful feedback, realistic goals, recognition, development opportunities, and effective management can all influence the employee experience. Performance management technology can support these practices by giving managers better visibility into employee progress.
Instead of discovering performance or engagement issues during annual reviews, organizations can establish continuous feedback processes. Managers can review goals regularly, recognize achievements as they happen, identify development opportunities, and address problems sooner.
Organizations should also examine operational factors such as workloads and project demands. Employee engagement initiatives will have limited impact if employees repeatedly work on understaffed projects with unrealistic deadlines. Connecting people data with operational and financial information provides a more complete foundation for retention decisions.
From Data To Action
Turning retention data into action
An employee retention percentage is valuable only when organizations use it to investigate patterns and improve workplace decisions.
Rather than viewing an 85% or 92% retention rate in isolation, compare the figure with previous periods. Examine which teams changed the most. Review performance and engagement information for those groups. Look at workloads, managers, goals, development opportunities, and project conditions.
Modern performance management systems can help centralize much of this information. AssessTEAM, for example, lets businesses manage employee evaluations, continuous feedback, KPIs, goals, OKRs, employee engagement, 360-degree feedback, and project performance information in a connected performance management environment.
That gives managers more context for understanding both employee performance and the conditions influencing it.
Common Questions
FAQs about employee retention rate
What is a good employee retention rate?
No single retention rate fits every organization. Retention varies based on industry, job type, workforce demographics, labor-market conditions, business growth, and company structure. The most useful approach is to compare your current retention rate with previous periods and investigate significant changes across departments or employee groups.
What is the formula for employee retention rate?
The standard formula is: Employee Retention Rate = (Employees remaining at the end of the period ÷ Employees at the beginning of the period) × 100. Employees remaining should typically represent workers who were present at the beginning and remained throughout the full measurement period.
How is employee retention different from turnover?
Employee retention measures the percentage of employees who remain with an organization, while turnover measures employees who leave. Tracking both can provide a clearer picture of workforce stability.
Can performance review software improve employee retention?
Performance review software can support retention by helping managers provide regular feedback, establish clear expectations, track employee goals, recognize achievements, and identify performance or engagement problems earlier. The software itself does not guarantee higher retention, but it can give managers better information to improve the employee experience.
How does performance evaluation software help HR teams track retention risks?
Performance evaluation software gives HR teams visibility into employee goals, KPIs, feedback, evaluation trends, and performance changes. Reviewing these patterns alongside retention and engagement data can help managers identify teams or employees that may require additional support.
How does project profitability analysis relate to employee retention?
Project profitability analysis can reveal workload, resource, budget, and productivity pressures that may also affect employees. Comparing project profitability with performance and retention trends can help managers identify situations where excessive workloads, poor resource allocation, or unrealistic project targets may be contributing to employee dissatisfaction.
Final Thoughts
The percentage is the start, not the answer
Employee retention rate is simple to calculate, but understanding what drives it requires a broader view of employee performance and the workplace experience. Start with the basic retention formula, track the metric consistently, and analyze results by team, role, manager, or location. Then connect those insights with employee goals, KPIs, feedback, engagement information, and performance reviews.
Performance review and evaluation software can make that process easier by giving managers ongoing visibility into employee progress, rather than relying solely on annual evaluations. For organizations managing client work or complex projects, combining workforce information with project profitability analysis can add another layer of insight. It helps leaders understand not only whether employees are staying, but also how workloads, project performance, productivity, and business results shape the employee experience.
Ultimately, retention becomes more actionable when organizations move beyond asking How many employees stayed? and begin asking What can our performance data tell us about why they stay?
