How to calculate turnover rate: free calculator and formula

The employee turnover rate formula, step by step

The turnover formula HR teams use, also called the turnover rate equation, is short. The care goes into counting the right people.

Turnover rate = separations ÷ average headcount × 100

1. 1Pick the period. A month, a quarter or a year. Use the same one every time you compare.
2. 2Count separations. Everyone who left the payroll during the period, for any reason (see who counts below).
3. 3Work out average headcount. Employees at the start plus employees at the end, divided by two.
4. 4Divide and multiply by 100. Separations divided by average headcount, times 100, is your turnover rate for that period.

Worked example: one month

A company has 120 employees on March 1 and 130 on March 31. Three people left during March.

Average headcount

(120 + 130) ÷ 2 = 125

Turnover rate for March

3 ÷ 125 × 100 = 2.4%

Projected for a year

2.4% × 12 = 28.8%

Worked example: a full year

A team starts the year with 80 people and ends it with 100. Eighteen people left at some point during the year, including some who were hired that year.

Average headcount

(80 + 100) ÷ 2 = 90

Annual turnover rate

18 ÷ 90 × 100 = 20%

If headcount swings a lot during the year, average the 12 month-end headcounts instead of using only the first and last day. It gives a fairer denominator for a company that doubled in size.

Who counts as a separation

Voluntary, involuntary and regrettable turnover

One total rate mixes very different stories. Track these alongside it.

Voluntary turnover

The employee chose to leave: resignations, and often retirements.

Tells you: How well you keep people. Most retention work aims here.

Involuntary turnover

The employer ended the job: dismissals, layoffs, eliminated roles.

Tells you: Hiring fit, performance management and restructuring.

Regrettable turnover

Leavers you would have rehired tomorrow, usually strong performers.

Tells you: The losses that hurt most. Even a small number here matters.

Non-regrettable turnover

Leavers whose departure the team can absorb or even welcomes.

Tells you: Whether a high total is a real problem or a healthy reshuffle.

First-year turnover

People who leave within 12 months of their start date.

Tells you: Hiring and onboarding quality. Divide by the number hired in that group.

The voluntary turnover rate uses the same formula with only voluntary leavers on top: 2 resignations and an average headcount of 125 is a 1.6% voluntary rate. Add the calculator’s optional fields to see both rates side by side.

Monthly vs annual turnover rate

Most HR reports show a monthly rate for spotting changes and an annual rate for the big picture.

• Annual rate from real numbers. All separations in the last 12 months divided by the average headcount over those months. This is the most reliable figure.
• Annual rate projected from a month or quarter. Multiply a monthly rate by 12 or a quarterly rate by 4. Quick, but one unusual month throws it off.
• Year to date. Separations so far divided by average headcount so far, then multiplied by 12 and divided by the months elapsed.
• Adding up months. The 12 monthly rates added together land close to the annual rate when headcount is steady.

Turnover rate vs retention rate

Retention rate is not 100 minus turnover. It follows only the people you had at the start: employees from the start still employed at the end, divided by employees at the start, times 100. Say 114 of your 120 starting employees are still with you at the end of the month. Retention is 95%. If 8 people left in total, including 2 hired that month, turnover is 8 ÷ 125, or 6.4%. The two numbers answer different questions, and a team that hires a lot needs both.

What employee turnover costs

The cost of a departure lands in five places, most of them outside the HR budget.

• Leaving. Exit paperwork, final pay, any unused vacation paid out, and the manager hours spent handing work over.
• The empty seat. Overtime, temps or contractors, work that waits, and customers who notice the gap.
• Hiring. Job ads, recruiter or agency fees, and the hours your team spends screening and interviewing.
• Getting up to speed. Training time, equipment and accounts, and the months before a new hire works at full pace.
• Knock-on effects. Lost know-how, strained client relationships and a heavier load on the people who stay, which can start the next resignation.

Is your turnover rate high? How to benchmark it

A rate means little on its own. Put it next to one of these.

• Your industry, through JOLTS. The US Bureau of Labor Statistics publishes monthly separations, quits and layoff rates by industry and region in its Job Openings and Labor Turnover Survey. Those are monthly rates, so compare them with your monthly rate.
• Your own history. Compare the same month last year, and the last 12 months with the 12 before, so seasonal swings don't fool you.
• Team by team. A company-wide rate hides the one team where people keep leaving. Split it by team, manager, location and role.
• By tenure. Separate first-year leavers from everyone else. A spike in the first 12 months points at hiring and onboarding.
• Voluntary only. Layoffs come in lumps and can swamp the signal. Track the voluntary rate on its own line.

The official numbers live in the BLS Job Openings and Labor Turnover Survey. JOLTS splits total separations into quits, layoffs and discharges, and other separations such as retirements, which maps neatly onto voluntary and involuntary turnover.

Top 10 reasons for employee turnover

The causes of staff turnover are rarely a surprise to the person leaving. They are often a surprise to the manager.

1. Their manager. Unclear expectations, little feedback, credit taken or a relationship that never clicked.
2. No visible next step. They can't see a promotion, a new skill or a bigger project anywhere ahead.
3. Pay that fell behind. Raises didn't keep up, and an outside offer shows them the gap.
4. A workload that never eases. Long hours stopped being a busy season and became the job.
5. The job isn't what was described. The role, schedule or team turned out different from the interview.
6. A rough start. No plan for the first weeks, no one to ask, and no early win.
7. Effort that goes unnoticed. Good work gets the same response as average work: none.
8. No flexibility. A schedule or location rule that clashes with their life, while other employers offer more.
9. No ties to the team. They know their tasks but not their colleagues, which is common for remote staff.
10. A culture they don't trust. Favoritism, unfair decisions, bad behavior that goes unchecked or leaders who say one thing and do another.

Much of this is fixable, and the warning signs come early. In a 2019 Gallup study, 52% of voluntarily exiting employees said their manager or organization could have done something to prevent them from leaving, and 51% of exiting employees said that in the three months before they left, neither their manager nor any other leader had spoken with them about their job satisfaction or future with the organization (Gallup, 2019). People who have quietly checked out show it first: see the signs in our guide to disengaged employees.

12 ways to reduce employee turnover

Start with the first two: they tell you which of the other ten to pick.

1. Find where it's happening. Split your rate by team, manager, role and tenure before you fix anything. Turnover is rarely spread evenly.
2. Get honest exit answers. Have someone other than the direct manager run exit conversations or an exit survey, and read the answers every quarter.
3. Ask the people who stay. Stay interviews tell you what keeps people and what would make them go, while you can still act on it.
4. Show the real job before the offer. Describe the hard parts of the role in interviews, so nobody discovers them in week three.
5. Plan the first 90 days. A written plan, a buddy and a first win cut the early exits that pull first-year turnover up.
6. Measure managers on retention. Give managers their team's voluntary turnover and survey scores, and train the ones who need it.

7. Check pay against the market every year. Fix the biggest gaps before an outside offer does it for you.
8. Make career paths visible. Publish what the next level looks like for each role and how people have reached it.
9. Watch workload signals. Overtime, vacation nobody takes and evening messages warn you before resignations do.
10. Recognize specific work, often. Name what the person did and why it mattered, in public when they're comfortable with it.
11. Offer flexibility where the job allows. Start and finish times, remote days or compressed weeks, with clear rules that apply to everyone.
12. Give people reasons to know each other. Colleagues who know each other are slower to leave. Mix new hires with long-timers at least once a quarter.
