Employee Turnover Rate Calculator

How to calculate employee turnover rate

1. Choose the period – a month, quarter or year.
2. Count separations: every employee who left for any reason during the period (resignations, dismissals, layoffs, retirements and deaths). Do not count internal transfers or promotions.
3. Work out the average headcount: (employees at start + employees at end) ÷ 2. For a year, averaging the twelve month-end headcounts is more accurate if your workforce changes a lot.
4. Divide separations by average headcount and multiply by 100.

Example: a company starts the year with 120 employees and ends with 130. Fifteen people left during the year. Average headcount = (120 + 130) ÷ 2 = 125, so the annual turnover rate = 15 ÷ 125 × 100 = 12%.

Monthly, quarterly and annual turnover

Many HR teams calculate turnover monthly and add up the months for the year. If an average of 100 employees saw 2 departures in March, March's turnover was 2%. A 2% monthly rate sustained all year adds up to roughly 24% annual turnover. To compare a part-year figure with full-year benchmarks, annualise it: a 5% rate over one quarter is about 20% annualised. Annualising assumes the same pace continues, so label it as an estimate – seasonal businesses can be very different from quarter to quarter.

Types of turnover worth separating

With 15 leavers – 11 voluntary and 4 involuntary – and an average headcount of 125, voluntary turnover is 8.8% and involuntary turnover is 3.2%. The calculator shows each rate so you can see which kind drives the total.

Turnover rate vs retention rate

Turnover and retention measure different things, so they do not always add up to 100%. Retention looks only at the people you had at the start: if 108 of your 120 starting employees are still with you at year-end, retention is 90%. Turnover includes everyone who left, including people hired and lost during the same year. A company that hires and loses many short-stay employees can have high turnover and still retain most of its long-standing staff.

What is a good turnover rate?

There is no single good number. Turnover varies widely by industry, job type, region and the economy: hospitality and retail typically see far higher rates than government or utilities, and hourly roles turn over faster than salaried ones. The most reliable external comparison in the US is the Bureau of Labor Statistics Job Openings and Labor Turnover Survey (JOLTS), which publishes monthly separation, quit and layoff rates by industry. Compare your monthly rate with the JOLTS rate for your industry, and – more importantly – with your own past figures.

Estimating the cost of turnover

Each departure costs money: recruiting and advertising, interview time, onboarding and training, overtime or agency cover while the role is empty, and lower productivity while a new hire gets up to speed. Estimates vary so much by role that the calculator asks you for your own cost per replacement. If replacing one employee costs about $12,000 and 15 people leave, turnover costs about $180,000 a year – a figure that makes retention programmes easier to justify.

How to reduce employee turnover

• Hold exit interviews and short 'stay interviews' with current staff to learn why people leave and stay.
• Check pay against the market for roles with the highest voluntary turnover.
• Improve onboarding: much early turnover happens in the first months.
• Train managers – an employee's direct manager has a large effect on whether they stay.
• Offer clear development paths and internal moves before people look elsewhere.
• Track turnover by team, manager, role and tenure so problems show up early.

Example: a year of monthly turnover

Adding the quarterly rates gives about 12.2%, close to the 12.1% you get by dividing the 15 leavers by the average headcount for the year. Small differences between the two methods are normal; pick one and use it consistently so year-on-year comparisons are fair.

Turnover by team, role and tenure

A company-wide rate can hide problems. If one team of 20 people loses 6 employees while the rest of a 200-person company loses 14, the company rate is 10%, but that team's rate is 30%. Run the calculator for each department, manager, location, job family and tenure band (for example, under one year, one to three years, over three years). Patterns – a single manager, a particular shift, new hires leaving in their first 90 days – point to fixes far more clearly than the overall number.
