Employee turnover rate is the number of employees who left during a period divided by the average headcount, times 100: 18 departures from an average headcount of 100 is an 18% annual turnover rate. Enter separations and start and end headcount below; add salary to see what turnover costs.

Employee Turnover Rate Formula

Turnover Rate = Employees Separated / Average Headcount × 100
Average Headcount = (Start HC + End HC) / 2

Industry Benchmarks

Industry Average Annual Turnover
Tech / Software 10–15%
Finance / Insurance 10–15%
Healthcare 15–25%
Retail 25–60%
Food & Hospitality 50–75%
Staffing agencies 100%+

The Real Cost of Turnover

SHRM (Society for Human Resource Management) estimates replacement costs range from 33% to 200% of annual salary, depending on the role:

Role Replacement Cost
Entry-level / hourly 33–50% of salary
Mid-level contributor 50–100% of salary
Senior / specialized 100–150% of salary
Executive / C-suite 150–200%+ of salary

Costs include: job postings, recruiter fees, interview time, lost productivity during vacancy, onboarding time, and new-hire ramp-up.

Worked example

A company starts the year with 110 employees, ends it with 90, and 18 people leave. Average headcount is (110 + 90) / 2 = 100, so turnover is 18 / 100 = 18% (rated High, above average) and retention is 82%. With an average salary of $60,000 and a 50% replacement cost, each departure costs $30,000, so turnover costs $540,000 a year.

Frequently asked questions

How do you calculate employee turnover rate? Divide the number of employees who left in the period by the average headcount (start plus end, divided by two) and multiply by 100.

What is a good employee turnover rate? This calculator treats 10% or less as low, 10 to 15% as average and above 25% as critical. Benchmarks differ widely by industry: tech sits around 10 to 15%, retail 25 to 60%.

Does turnover include layoffs and retirements? It can include any separation. Many teams track voluntary turnover (resignations) separately, because it is the part you can influence.

How do you annualize monthly turnover? Add up the separations over twelve months and divide by the average headcount for the year; multiplying a single month's rate by 12 is only a rough shortcut.

What does turnover cost? Replacement cost is commonly estimated at 33% to 200% of annual salary depending on seniority, covering recruiting, vacancy, onboarding and ramp-up.

How to Calculate Employee Turnover Rate

Step-by-step formula for employee turnover rate, how to compute average headcount correctly, and common calculation mistakes to avoid.

Employee turnover rate is one of the simplest HR metrics to calculate — and one of the easiest to get subtly wrong by using the wrong headcount denominator.

The formula

Turnover Rate = Employees Separated / Average Headcount × 100
Average Headcount = (Start Headcount + End Headcount) / 2

A worked example

You start the year with 80 employees, end with 100, and 15 people left during the year (voluntary and involuntary combined).

Average headcount = (80 + 100) ÷ 2 = 90 Turnover rate = 15 ÷ 90 × 100 = 16.7%

Note this isn't 15 ÷ 100 (18.75%, using ending headcount) or 15 ÷ 80 (18.75% coincidentally the same here, using starting headcount) — using the average is the standard SHRM method and matters more the faster you're growing or shrinking.

Monthly vs annual turnover rate

Calculating monthly turnover and multiplying by 12 overstates annual turnover, because it doesn't account for compounding — the same employee can't leave twice. For an accurate annualized figure, sum actual separations over the full 12-month period and divide by the 12-month average headcount, rather than annualizing a single month's rate.

Voluntary vs involuntary turnover

Total turnover rate blends voluntary departures (resignations) and involuntary ones (layoffs, terminations). Track them separately — a spike in voluntary turnover signals a retention problem; a spike in involuntary turnover signals a hiring or performance management issue. Blending them hides which lever to pull.

Frequently asked questions

Should retirements count as turnover? Most HR teams count retirements as voluntary turnover in the raw rate, but flag them separately in analysis since they're rarely preventable or a signal of dissatisfaction.

What counts as "separated" — does it include internal transfers? No. Internal transfers and promotions are not turnover; only people who leave the organization entirely count as separations.

Use the Employee Turnover Calculator to compute your rate automatically from separations and headcount.

The True Cost of Employee Turnover

Why replacing an employee costs 33–200% of their annual salary, what drives that cost, and how to estimate the total financial impact of your turnover rate.

Most managers underestimate turnover cost by focusing only on the visible line items — job board fees, agency commissions — while ignoring the much larger hidden costs of lost productivity and ramp-up time.

What actually goes into the cost

  • Vacancy cost: lost output while the role sits empty, plus the burden on remaining team members covering the gap
  • Recruiting cost: job postings, agency fees (typically 15–25% of first-year salary for external recruiters), and internal interview time
  • Onboarding and training: formal training programs plus the time managers and peers spend getting a new hire productive
  • Ramp-up productivity loss: a new hire typically operates below full productivity for 3–6 months, sometimes longer for specialized or senior roles

SHRM's benchmark figures

SHRM (Society for Human Resource Management) puts total replacement cost at 33% of annual salary for entry-level roles, rising to 150–200% for senior or highly specialized positions. On a $70,000 role, that's $23,000–$140,000 per departure depending on seniority.

Why this number surprises most leaders

The gap between the "obvious" cost (recruiting fees, maybe $5,000–$10,000) and the true cost (which includes months of below-peak productivity from the new hire and the disruption to the team) is usually 5–10×. Turnover cost is mostly invisible in a normal P&L because it's spread across payroll, not booked as a discrete line item.

Turning the number into a retention business case

If your annual turnover rate is 20% on a 50-person team earning an average $80,000, that's 10 departures/year at conservatively 75% of salary = $600,000/year. A retention initiative — better onboarding, manager training, competitive pay reviews — that cuts turnover to 15% saves $150,000/year, which easily funds most retention programs.

Frequently asked questions

Does this cost estimate include severance? Not directly — the calculator focuses on replacement cost (recruiting, vacancy, onboarding). Add severance and any COBRA/benefits continuation separately for involuntary departures.

Is the cost different for remote roles? Vacancy and ramp-up costs are similar; recruiting costs can be lower (larger candidate pool, no relocation) but onboarding often takes longer without in-person mentorship.
