How to Calculate Employee Retention Rate: The Formula

Understanding the employee retention rate formula is essential for any organization focused on long-term growth, talent development, and workplace stability. Retention is not just about keeping people—it’s about keeping the right people, and ensuring they thrive. As a Talent Acquisition Leader or HR professional, your ability to measure and act on retention metrics can significantly impact your company’s success, workforce strategy, and bottom line.

Why Employee Retention Matters

Effective employee retention is a cornerstone of sustainable HR strategy. High retention rates signal a healthy workplace culture, engaged employees, and optimized hiring practices. Low retention, on the other hand, is often a red flag—indicating issues with satisfaction, compensation, career development, or even poor leadership.

Retention isn't just about saving on hiring costs (though it does); it directly influences productivity, morale, and company reputation. A consistently high employee retention rate supports business continuity and team cohesion.

Understanding the Employee Retention Rate Formula

So, what’s the actual formula? Let’s break it down.

The Retention Rate Formula:

Retention Rate = (Number of Employees Who Remain During a Period / Number of Employees at the Start of the Period) × 100

This rate formula gives you a percentage of employees who stayed with your organization over a given period.

For example, if you started the year with 100 employees, and 85 of them are still on your team at the end of the period, your employee retention rate would be:

(85 / 100) × 100 = 85%

That’s a solid retention rate, especially in high-turnover industries.

How to Calculate Your Employee Retention Rate

Let’s walk through the steps to calculate employee retention effectively:

Step 1: Set Your Time Frame

Determine the period of time you're evaluating—typically a year, quarter, or month, depending on your organization’s review cycles.

Step 2: Identify the Total Number of Employees at the Start

This is your baseline. It's the total number of employees on day one of your selected period.

Step 3: Determine How Many Employees Stayed

Count the employees who remain at the end of the period who were also present at the beginning (i.e., not new hires).

Step 4: Plug Into the Formula

Divide the number of retained employees by the original count and multiply by 100 to get your employee retention rate.

Step 5: Analyze and Act

Use this metric to track trends, compare retention rates across departments, and calculate retention across varying lengths of employment.

Why Retention Rate Can Make or Break Talent Strategy

A strong employee retention rate indicates your organization is doing something right—be it development opportunities, a great work environment, or attractive compensation and benefits. Conversely, a low retention rate can also point to high turnover, low employee satisfaction, and disengagement.

This rate isn’t just a number—it’s a reflection of how well your company supports its people.

Common Pitfalls in Calculating Retention Rates

Even seasoned HR teams can make missteps in their rate calculation. Watch out for:

• Including new employees who joined mid-period
• Failing to define a clear time period
• Not accounting for voluntary turnover vs. layoffs

If you're trying to calculate employee retention accurately, consistency is key. Always align your rate analysis with clearly defined terms and policy guidelines.

Retention and Turnover: Two Sides of the Same Coin

To calculate your employee retention rate, you're essentially flipping the logic used for turnover rate. The turnover rate looks at how many employees leave, while retention rate focuses on those who stay.

Here’s a comparison:

• Turnover Rate = (Employees Who Left / Average Number of Employees) × 100
• Retention Rate = (Employees Who Stayed / Number at Start) × 100

Both rates provide valuable insight. By measuring both, companies can get a full picture of the workforce dynamics.

What Is a Good Employee Retention Rate?

While industry benchmarks vary, a high retention rate is generally above 85–90%. However, a “good” employee retention rate depends on your sector, company stage, and employee experience strategy.

Early-stage startups, for instance, might experience higher turnover due to rapid scaling, while mature enterprises often aim for greater stability.

Regularly tracking your retention rate allows you to find gaps and improve retention strategies that match your unique goals.

Factors That Impact Employee Retention

To increase your retention rate, consider the following employee retention strategies:

1. Offer Development Opportunities

Clear career paths, internal mobility, and ongoing training programs all help employees stay and grow.

2. Prioritize Job Satisfaction

Foster employee satisfaction through consistent feedback, fair compensation, and recognition.

3. Improve the Work Environment

Focus on health insurance, work-life balance, and a company culture that promotes well-being.

4. Leverage Data and Analytics

HR teams can use predictive tools to track turnover rates and understand what drives employees to leave or stay.

How to Use Retention Rate Insights

Once you’ve done your retention rate calculation, it’s time to act. Here’s how you can help your organization turn numbers into strategy:

• Identify patterns across teams or locations with low retention
• Boost employee development and support programs
• Introduce solutions like GoPerfect to intelligently source and match better-fit talent who are more likely to stay
• Use feedback loops (like pulse surveys) to monitor employee satisfaction

By tapping into these insights, your company can improve employee retention and build a culture where employees want to stay.

What Makes Retention Rate Important for Recruiters?

Recruiters need to measure their retention impact just as much as their placement rate. A high employee retention rate suggests that hires are aligned with the organization’s culture, expectations, and job fit.

This feedback loop helps hr teams and talent leaders continuously improve recruitment practices—especially when it comes to sourcing candidates who align with long-term success.

And if you're using a platform like GoPerfect, which combines semantic search, outreach automation, and smart integrations, you can get ahead of turnover rates by sourcing employees who stay.

Retention Rate in Action: A Quick Example

Let’s calculate the retention rate with this scenario:

• You had 120 employees at the start of Q1.
• 10 employees left, and 110 remained at the end of the period.
• The number of employees at the start = 120
• The number who stayed = 110

Retention Rate = (110 / 120) × 100 = 91.6%

This rate reflects a strong ability to retain talent and could signal that your retention strategies are working well.

Take Action on Retention Insights

Tracking your employee retention rate isn’t a one-off task—it’s an ongoing priority. Use your retention rate formula as a diagnostic tool, then use the insights to improve retention, reduce turnover, and better support your employees.

The more you invest in employee experience, the more likely employees will stay—and that’s what makes retention rate important for every talent leader.

If you're ready to go beyond measurement and drive real change, platforms like GoPerfect can provide the AI-powered support your hr team needs to source, engage, and retain top talent—smarter and faster.
