Retention Rate:
Definition & Comparison

Employee retention rate is a metric that measures the percentage of employees who remain employed at a company over a specific period of time. This vital measurement allows organizations to gauge the success of their human resource practices, including aspects such as employee development and engagement initiatives. It's the inverse of turnover rate, which measures the rate at which employees leave their jobs.

Retention rates reflect how employees feel about an organization, their work environments, and their roles. A high retention rate indicates that your organization is effectively managing the needs of its workforce, leading to greater loyalty, productivity, and better overall working performance. Conversely, a low retention rate could signal potential issues such as poor communication, inadequate compensation, or a work environment that doesn't nurture employee development.

The retention rate formula is straightforward and provides a clear snapshot of workforce stability. The calculation is: (Total workforce headcount – Number of employees who leave) / Total workforce headcount × 100.

When calculating retention rate, it's important to outline a timeframe you would like to measure, most commonly quarterly or annually. The calculation should not include employees who were hired during the middle of the measurement period, as this can skew results. Here are 3 practical examples:

• Example 1: A research and development company had 100 employees at the start of the year. Within the last year, 5 employees left. Retention rate = ((100 – 5)/100) × 100 = 95%
• Example 2: A large manufacturing company had 10,000 employees at the start of the fiscal year, but 1,500 employees left by the end of the year. Retention rate = ((10,000 – 1,500)/10,000) × 100 = 85%
• Example 3: A multi-national chain with 50,000 employees worldwide closes 500 stores, affecting 15,000 employees. Retention rate = ((50,000 – 15,000)/50,000) × 100 = 70%

A more accurate alternative to annual calculations is to look at length of service, or employee tenure, by determining the number of people employed for each year of service. Tenure helps organizations understand where institutional knowledge resides, anticipate retirements, and approach recruitment, training, and succession planning strategically.

As a rule of thumb, a retention rate of 85-90% or higher is considered good for most industries. According to the Bureau of Labor Statistics, the average turnover rate in 2024 was 3.3%, which means the average retention rate is around 96.7%.

However, what constitutes a good retention rate varies significantly by industry, organization size, and job type. ADP data shows that hospitality, retail, and resources and mining have the lowest monthly retention rates of 97% or lower. Education and health, finance, manufacturing, information, and professional services have the highest monthly retention of 97.7% or higher.

Organization size is also significant. Retention rates at smaller organizations can vary widely, from 95% to 100%. As organizations grow, turnover declines and retention rates increase, partly due to scale. Industries such as retail or entertainment commonly see higher levels of employee turnover compared to more stable sectors.

It's worth noting that a very high retention rate, like 99%, may not always be optimal. Some turnover helps create career paths for high-performing employees within your company or allows you to attract external talent. Employers may also want to address low-performing employees through involuntary turnover to make the company more productive and efficient.

Employee retention rate is important because it directly impacts your organization's financial health, productivity, and workplace culture. Poor retention rates can be an expensive problem, even replacing just one employee can cost an organization one-half to two times the employee's yearly salary. That cost rises significantly if many employees leave.

High retention rates deliver 4 key business benefits:

1. Reduced company costs: According to Bain & Company research, a 5% increase in customer retention generates more than a 25% boost in profit. This principle applies to employee retention as well, as you avoid constant recruitment and onboarding costs like job ads, interviews, and lengthy training sessions
2. Increased employee productivity: Employees who stay longer know the ins and outs of their roles, leading to increased efficiency and quicker problem-solving. Organizations with strong onboarding see productivity rise by over 70%
3. Improved engagement and satisfaction: High retention rates signal a work environment where employees feel respected and supported. Almost 90% of employees report being engaged after a positive onboarding experience
4. Protected institutional knowledge: High turnover can harm the morale and productivity of current staff, disrupt client relationships, and rob organizations of competitive skill sets and institutional knowledge

Talented workers are your organization's most valuable asset. Without them, you won't be able to achieve business goals or drive key initiatives. Almost 40 million people quit their jobs in 2024, representing an 11% reduction from 2023 quit rates but still a significant disruption to business operations.

Employee retention rate and turnover rate are two sides of the same coin, as they each represent different aspects of an organization's ability to nurture and maintain a workforce. One is the inverse of the other.

Retention rate measures how well an employer keeps valued employees, the percentage of employees who stay with a company over a given timeframe. Turnover rate measures how many employees leave a company during that same period, whether through voluntary or involuntary departures.

If a company has a turnover rate of 3% during a given period, the retention rate for that same time is 97%. Your retention rate complements your turnover rate metric. Analyzing both together gives you a holistic view of employee transition compared to either metric alone.

Separating calculations by voluntary and involuntary turnover allows you to compare the percentage of terminated staff members to the percentage of employees who left your organization by choice. This data helps you make necessary changes to your retention strategy.

Improving employee retention rate requires understanding the wants and needs of your workforce through data-driven strategies rather than assumptions. Employee reasons for staying and leaving are individualistic, which means one-size-fits-all approaches rarely work.

There are 6 proven strategies to increase retention rates:

1. Improve recruiting and onboarding processes: Organizations with strong onboarding improve new-hire retention by 82% and productivity by over 70%. Successful companies are 35% more likely to start onboarding before an employee's first day
2. Provide competitive compensation and benefits: When employees perceive a pay gap, it results in a 16% decrease in intent to stay. Ninety-two percent of employees value health benefits as part of their compensation package
3. Create a positive work environment: Cultivate a workplace that encourages open communication and supports work-life balance. Fifty-three percent of workers say they'd be willing to take a pay cut for better work-life balance, and 50% say they'd take less money to guarantee flexibility in how they structure their hours
4. Offer career growth and development opportunities: When employees see a clear path for growth within your organization, they're 63% more likely to stay motivated and committed for the long term. Ninety-four percent of employees are more likely to stay with their employer if they provide learning and development opportunities
5. Implement reward and recognition programs: Celebrate achievements through formal and informal recognition programs to boost morale and reinforce the value each employee brings to the company
6. Check in with employees frequently: Team members who are fully engaged are at least 1.8 times less likely to leave voluntarily within six months. Regular feedback through surveys and exit interviews helps identify areas for improvement

Retention rates are the symptom of a potential problem, not the cause. To reduce turnover, employers must understand the wants and needs of their workforce through data-driven approaches. According to Forbes, it can cost a business five times more to attract and earn a new customer than retain an existing one, the same principle applies to employees.

It's common practice to review retention rates quarterly. This timeframe helps employers identify turnover before it becomes a wide-scale problem and assess whether retention initiatives are effective.

Calculating retention rates regularly allows you to compare data over time and identify trends. Choosing specific time spans and jobs to analyze enables you to discover weak areas in need of adjustment. Additionally, calculating the retention rate for each department, as well as for the company as a whole, provides a comprehensive picture of overall employee retention status.

Modern HR technology solutions and analytics tools can track and analyze employee data continuously. By leveraging HR tech such as human resource information systems (HRIS) and employee management software, HR leaders can store and manage employee data, monitor performance, and generate reports on various HR metrics, including retention and turnover rates.

Retention rates vary significantly across different industries based on job characteristics, workforce demographics, and industry dynamics. Industries with the highest retention rates include government and finance, while the lowest rates are in the food and hospitality industry.

Average retention rates by sector show distinct patterns. Education and health, finance, manufacturing, information, and professional services maintain monthly retention rates of 97.7% or higher. In contrast, hospitality, retail, and resources and mining sectors experience lower monthly retention rates of 97% or below.

These variations reflect the nature of work in each sector. Industries with seasonal employment, part-time positions, or entry-level roles tend to experience higher turnover. Sectors requiring specialized skills, offering career advancement opportunities, and providing competitive benefits typically maintain higher retention rates.

Retention rate is often compared to 3 related HR metrics:

Retention Rate vs. Turnover Rate

Retention rate measures the percentage of employees who stay with a company, while turnover rate measures the percentage who leave. If a company has a 3% turnover rate, it has a 97% retention rate for the same period. Both metrics provide complementary insights, retention shows what's working well, while turnover highlights areas needing improvement.

Retention Rate vs. Churn Rate

Churn rate is essentially synonymous with turnover rate, though it's more commonly used in subscription-based businesses and customer relationship contexts. In HR, churn rate refers to the rate at which employees leave, making it the inverse of retention rate. Some organizations prefer "churn" terminology when analyzing voluntary departures specifically.

Retention Rate vs. Employee Tenure

Employee tenure tracks how long individual employees have worked at an organization, while retention rate measures the percentage of the workforce that stays over a defined period. Tenure provides granular, individual-level data about length of service, helping identify where institutional knowledge resides and anticipate retirements. Retention rate offers a broader, organizational-level view of workforce stability and the effectiveness of HR practices.
