Quick answer: To calculate your annual cost of turnover, multiply your total headcount by your annual turnover rate to get employees lost, multiply your average annual wage by a replacement cost multiplier (0.5x to 2x, based on role seniority) to get cost per employee, then multiply those two numbers together. A 450-person plant at the manufacturing industry average of 28% turnover, with a $42,000 average wage and a 0.75x multiplier, loses approximately $3.97 million a year.
Every plant manager knows turnover is expensive. Few can put a number on it.
That gap matters. Without a real figure, turnover stays a background frustration instead of a budget line leadership has to act on. Once you can say “losing our machine operators is costing us $410,000 a year,” the conversation changes. Retention stops being an HR request and becomes a financial one.
Here is how to calculate that number for your own plant, what the industry benchmarks actually say, and a free calculator that does the math for you.
The Formula
Turnover cost comes down to three numbers:
- Employees lost annually = total headcount × annual turnover rate
- Cost per employee lost = average annual wage × replacement cost multiplier
- Total annual cost = employees lost × cost per employee
The formula is simple. The inputs are where most manufacturers get it wrong, usually by underestimating the replacement multiplier or not knowing their real turnover rate at all.
What Counts as “Replacement Cost”
Replacement cost is not just the price of a job posting. It covers recruiting time, interviewing, onboarding, training, the productivity gap while a new hire ramps up, and the overtime or temp labor that covers the vacancy in the meantime.
Both Gallup and SHRM put this at 50% to 200% of the departing employee’s annual salary, depending on how senior or specialized the role is. Frontline and entry-level roles tend to sit at the low end of that range. Skilled trades and supervisory roles run higher, since they take longer to fill and longer to train up to full output. That gap between frontline and skilled trades replacement cost is a big part of what skilled trades turnover is actually costing manufacturers, where per-departure costs commonly run $10,000 to $40,000 for a single production or skilled trades worker.
For a plant with a mix of general production and skilled trades workers, blending these rates across your workforce gives a far more accurate total than applying one flat percentage to everyone.
Where Manufacturing Actually Stands
Two independent sources put manufacturing’s annual turnover rate in a tight range:
- BLS JOLTS (2025 annual data): manufacturing’s separations rate averages 2.4% per month, which works out to roughly 29% annualized.
- Manufacturers Alliance (2024 Workforce Trends Survey, 192 companies): 26.3% average total turnover.
That puts the industry benchmark at roughly 28% annually, well above the all-industry average and second only to hospitality and retail among major sectors. For context, a 450-person plant running at the industry average turnover rate is losing and replacing well over 100 people a year.
Turnover also is not evenly distributed. Production and general labor roles tend to run 30% to 38% annually, while skilled trades positions run lower, closer to 12% to 18%, since those workers are harder to replace and tend to have deeper ties to a plant once they are trained. That gap is exactly why the multiplier matters as much as the headcount.
How to Calculate Your Own Number, Step by Step
- Pull your headcount. Use your total plant or site headcount, not just one shift or department.
- Find your actual annual turnover rate. Total separations over the past 12 months, divided by average headcount. If you only track monthly numbers, multiply the average monthly rate by 12 for a directional annual figure.
- Get your average annual wage. Blend across roles if your workforce spans multiple pay bands.
- Choose a replacement cost multiplier. Use 0.5x for frontline and entry-level roles, up to 2x for supervisory or highly specialized positions, per the Gallup and SHRM benchmarks above.
- Run the formula. Employees lost × (average wage × multiplier) = your total annual cost of turnover.

Why the Number Is Usually Higher Than People Expect
Most plant leaders who run this calculation for the first time are surprised, and not in a good way. A few reasons the real number tends to run higher than gut instinct suggests:
- Turnover compounds. Every departure adds training burden to the people who stay, which raises the odds that they leave too.
- Skilled trades cost more to replace than their wage suggests. A $65,000 maintenance technician replaced at a 1.5x multiplier is a $97,500 loss, not a $65,000 one.
- Vacancy time is rarely free. Overtime, temp staffing, and missed production targets during an open req add real dollars that never show up on an HR spreadsheet.
From a Number to a Plan
Calculating the cost of turnover is the easy part. The harder question is what is actually driving people out the door, and whether you would know before they hand in notice.
Annual engagement surveys typically catch problems long after the fact. Employees usually check out 60 to 90 days before they formally resign, which means a once-a-year survey cycle misses the window where a plant could still intervene. Pairing a real cost figure with more frequent, plant-floor-accessible listening (SMS, kiosk, and multilingual options included) gives manufacturers a chance to catch turnover risk while there is still time to act on it, not just measure it after the fact.

Frequently Asked Questions
How do you calculate the cost of turnover per employee?
Multiply the departing employee’s annual wage by a replacement cost multiplier, typically 0.5x to 2x depending on role seniority and how specialized the position is. A $50,000 production employee replaced at 0.75x costs approximately $37,500 to replace.
What is a good turnover rate for a manufacturing company?
Below the industry average of roughly 28% annually is a reasonable target, though the right benchmark depends heavily on role mix. Skilled trades positions should trend closer to 12% to 18%, while general production roles more commonly run 30% to 38%.
Why is manufacturing turnover so much higher than other industries?
Physical demands, shift work, and close wage competition with logistics and warehousing employers all contribute. Manufacturing’s turnover rate significantly exceeds the all-industry average, though it remains below high-churn sectors like hospitality and retail.
Does replacement cost really reach 200% of salary?
For senior, specialized, or hard-to-fill roles, yes. Gallup and SHRM both cite a 50% to 200% range, with the high end reserved for roles that take the longest to recruit and the longest to ramp to full productivity.
