Formula
Worked example
A company begins the year with 120 employees and ends with 114. During the year 12 people left. Average headcount = (120 + 114) / 2 = 117. Turnover rate = (12 / 117) x 100 = 10.3%. If 8 of those 12 left voluntarily, voluntary turnover = (8 / 117) x 100 = 6.8%. With an average salary of $65,000 and a 1.5x replacement cost multiplier, total replacement cost = 12 x $65,000 x 1.5 = $1,170,000.
What is employee turnover rate?
Employee turnover rate is the percentage of your workforce that leaves the organization over a given period, expressed relative to the average headcount during that window. It is one of the most-watched workforce health metrics in HR because it captures attrition cost, engagement, and organizational stability in a single number. High turnover is costly: researchers at the Society for Human Resource Management (SHRM) consistently estimate replacement costs at 0.5 to 2 times an employee's annual salary, covering recruiting fees, lost productivity during the vacancy, onboarding time, and the learning curve for the replacement. A low, stable turnover rate is a signal of healthy culture, competitive pay, and good management. An unusually low rate can occasionally indicate a stagnant workforce, so it is worth reading the number alongside engagement scores and internal mobility data.
Voluntary vs. involuntary turnover: why the split matters
Total turnover lumps together two fundamentally different workforce events. Voluntary turnover covers resignations, retirements, and departures the employee initiated. It reflects how employees feel about pay, culture, career growth, and management. Involuntary turnover covers dismissals, layoffs, and end-of-contract separations driven by the organization. Each type calls for a different response. High voluntary turnover is typically addressed through compensation benchmarking, better onboarding, clearer career paths, or management training. High involuntary turnover might reflect performance management gaps, poor hiring selection, or a business contraction. Tracking both separately lets you target improvement efforts where they will actually have an effect.
How to calculate employee turnover rate
The standard formula recommended by SHRM uses the average headcount during the period rather than a single snapshot: Turnover Rate = (Departures / Average Headcount) x 100, where Average Headcount = (Starting employees + Ending employees) / 2. Using the average smooths out the distortion caused by growth or contraction within the period. For voluntary turnover, replace the numerator with only the voluntary departures. For involuntary turnover, use only the company-initiated separations. Many organizations calculate a monthly rate and annualize it by multiplying by 12, which makes short periods comparable to annual benchmarks. One important note: internal transfers and promotions should not be counted as departures in any of these figures.
Understanding replacement cost and its drivers
Replacement cost is the total financial burden of losing an employee and bringing a replacement to full productivity. It typically includes job posting and agency fees (averaging $4,000 to $20,000+ depending on the role), interviewing and assessment time from hiring managers and HR, the productivity gap during the vacancy and the new hire's ramp-up period, and formal training costs. SHRM places average replacement at around 50% of annual salary for entry-level roles and up to 200% or more for senior specialists or executives. For a team with 12 departures and average salaries of $65,000, even a modest 1.5x multiplier produces a $1.17 million annual cost, which explains why small improvements in retention can generate significant savings.

Frequently asked questions
What is a good employee turnover rate?
For most industries, an annualized turnover rate below 10% is considered low and healthy. The U.S. all-industry average sits around 18-22% per year, so organizations in that range are typical, not excellent. Top-performing companies in most sectors target below 10-12%. Hospitality, retail, and food service have structurally higher rates, often 40-70%, where achieving below 40% is already a strong result. Always compare your rate to your own industry rather than an overall average, because the right benchmark varies considerably by sector.
Should I include new hires who left quickly in the turnover rate?
Yes, any employee who was formally on payroll and then separated during the period should be counted, regardless of tenure. Many organizations track "early attrition" or "30/60/90-day turnover" as a separate supplementary metric, because it specifically flags onboarding and selection problems, but those same individuals still belong in your overall turnover count.
What is the difference between turnover rate and attrition rate?
The two terms are often used interchangeably, and in practice many HR teams treat them as synonyms. When a distinction is drawn, attrition usually refers specifically to positions that are not backfilled after the departure, often used during headcount reductions or natural runoffs, while turnover implies the role will be filled again. For most calculations the same formula applies regardless of which term is used.
How do I annualize a monthly or quarterly turnover rate?
Multiply the period rate by (12 / number of months in the period). A monthly rate of 1.5% annualizes to 1.5 x 12 = 18%. A quarterly rate of 4% annualizes to 4 x (12/3) = 16%. This calculator performs the annualization automatically when you select the measurement period.
Can turnover rate be too low?
Potentially yes. Very low turnover can indicate that poor performers are staying too long, that high performers lack external options (common in niche roles or difficult job markets), or that the organization has little fresh talent coming in. Most workforce experts view a healthy baseline of around 5-8% voluntary turnover as beneficial, because it creates room for promotions, new perspectives, and skills refreshment. A rate near zero for several years is worth investigating alongside engagement and performance data.
Are retirements and internal transfers counted?
Retirements are typically counted as separations because the headcount slot becomes vacant. Internal transfers and promotions are not counted, because the employee remains with the organization. The key test is whether the person is still employed by the company at the end of the period: if yes, they do not count as a departure regardless of what role they moved into.
