Employee retention vs turnover.

Retention and turnover sound like opposites, but they are calculated differently and answer different questions. Using the right one, or both, makes workforce decisions clearer.

What is the difference between retention and turnover?

Retention measures how many of the people you had at the start of a period are still with you at the end. Turnover measures how many people left during the period, compared with your average headcount. Retention focuses on stability of the existing workforce; turnover focuses on how much the workforce churned. They do not always add up to 100%, because turnover also counts people hired and lost within the same period.

Key takeaways
  • Retention rate: share of starting employees still employed at the end.
  • Turnover rate: leavers divided by average headcount.
  • They do not simply add up to 100%.
  • Report both, and split turnover into voluntary, involuntary and regretted.
  • Early warning comes from engagement and capacity, not from either rate.

A worked example.

A team starts the year with 50 people. During the year, 8 of them leave. The team also hires 10 people, and 2 of those new hires leave before the end of the year. It ends with 50 people.

Leavers8 original + 2 new hires10
Average headcount(50 + 50) ÷ 250
Turnover rate10 ÷ 50 × 10020%

Retention (84%) and turnover (20%) add up to 104%, not 100%, because two people were hired and left within the year. That gap is why the two metrics should not be treated as mirror images.

Types of turnover.

  1. 1
    Voluntary. People choose to leave.
  2. 2
    Involuntary. The organization ends the employment.
  3. 3
    Regretted. People you wanted to keep leave. The most important number.
  4. 4
    Early turnover. People leave within their first year, often a sign of hiring or onboarding problems.

Which metric to report.

Report both if you can, and pick one as the headline for each audience. Leaders interested in stability and key talent usually prefer retention. Finance and workforce planning usually prefer turnover, because it links to hiring volume and cost. Whatever you choose, define it clearly and keep the definition stable so trends are comparable. See how to calculate turnover rate and how to calculate retention rate.

Common calculation mistakes.

  1. 1
    Using end-of-period headcount. Use average headcount for turnover to avoid distortion in growing or shrinking teams.
  2. 2
    Counting internal moves as turnover. Transfers between teams are not leavers for the organization.
  3. 3
    Mixing contractors and employees. Decide who is in scope and keep it consistent.
  4. 4
    Comparing different periods. Monthly and annual rates are not comparable without conversion.
  5. 5
    Ignoring small-team noise. One leaver in a team of five is 20%; look at trends, not single figures.

Context: how much people move.

Turnover varies widely by industry, role and labor market. For context, the US Bureau of Labor Statistics reported 3.4 million quits in the United States in September 2026, a monthly quits rate of 2.1%, and total separations of 5.3 million, a rate of 3.3%. Compare your own rates with your history and with similar roles rather than with a single universal benchmark.

Why both metrics look backward.

Retention and turnover tell you what already happened. By the time they move, the reasons have been building for months. The earlier signals are falling engagement and falling capacity: people losing commitment, or losing the energy, recovery and focus to keep going. Exhaustion is one of the most common reasons good people leave. Read more in engagement and retention.

Retention and turnover in the same report.

A simple quarterly report can show both: retention of the people you started the year with, turnover against average headcount, regretted turnover and first-year turnover, each by team. Add engagement and capacity scores for the same teams. Leaders then see stability, churn and early warning in one place, and can ask the right question: which teams are about to move in the wrong direction, and what will we do about it?

When the two tell different stories.

Sometimes retention looks healthy while turnover looks high. That usually means a stable core of long-serving people and heavy churn among new hires, a sign of hiring or onboarding problems. The opposite pattern, low turnover but falling retention of key people, can mean you are losing experienced staff while replacing them quickly. Reading both together shows which problem you have.

Reporting to leadership.

Leaders need both numbers, clearly defined, with a trend and a short explanation. Show retention of key roles, regretted turnover and first-year turnover by team, next to engagement and capacity. Highlight teams where the early signals are falling.

Bringing it together.

Retention shows stability, turnover shows churn, and regretted turnover shows where to focus. Add engagement and capacity to see who might leave next.

Using retention and turnover together.

  1. 01
    Track both by team. Company averages hide the teams where people leave.
  2. 02
    Separate regretted turnover. Focus effort where it matters most.
  3. 03
    Watch first-year turnover. A sign of hiring or onboarding problems.
  4. 04
    Read exit themes. Group reasons into manager, growth, pay, workload and personal.
  5. 05
    Add early signals. Engagement and capacity scores from regular surveys.
  6. 06
    Act and re-measure. Compare each team with its own baseline every quarter.

Monthly and annual rates.

Monthly turnover is useful for spotting changes quickly. To compare with annual figures, add up the monthly leavers over twelve months and divide by the average headcount across the year, rather than multiplying one month by twelve, which exaggerates seasonal spikes. Report the period clearly every time you share a rate.

Keep definitions consistent.

Write down your definitions once and use them everywhere.

Breaking rates down by segment.

Company-wide rates hide the story. Break retention and turnover down by team, role, location, tenure band and manager, and look for outliers. A team with twice the turnover of similar teams doing the same work usually has a management or workload problem, not a labor market problem. First-year turnover by hiring channel shows which sources bring people who stay. Keep segments large enough to be reliable, and read small-team figures as trends over several quarters rather than single numbers.

The cost of turnover.

Each leaver brings recruiting costs, onboarding time, lost output and extra load on colleagues, which can push the next person to leave. Putting a number on it helps make the case for earlier action. See the cost of employee turnover.

What a good rate looks like.

There is no single good turnover or retention rate. It depends on industry, role, location and the labor market. Entry-level and hourly roles usually turn over faster than specialist and senior roles. Compare each team with its own history and with similar roles inside your organization, and pay most attention to regretted turnover in roles that are hard to fill.

Measure it

thrive at work measures engagement (purpose, leadership, connection, growth) and capacity (energy, recovery, focus, resilience) in one anonymous assessment: see how the assessment works.

See who is about to leave

Turnover numbers only show who has already gone. thrive at work is a workforce performance platform: an employee engagement platform that reads engagement next to capacity to perform, so you can spot the teams at risk months earlier. Read more about employee engagement.

Common questions

Is retention the opposite of turnover?
Not exactly. Retention looks at the people you started with; turnover counts all leavers against average headcount, including new hires who leave.
How do you calculate retention rate?
Employees at the start of the period who are still employed at the end, divided by employees at the start, times 100.
How do you calculate turnover rate?
Leavers during the period divided by average headcount, times 100.
Why don't retention and turnover add up to 100%?
Because turnover also counts people who were hired and left within the same period.
Which is better to track?
Both. Retention for stability, turnover for planning and cost, and regretted turnover for focus.
