What employee turnover costs in a manufacturing plant

How turnover affects production

When an operator leaves, the shift still needs coverage. That often means overtime, temporary coverage, or slower production while a replacement is trained. Track those costs for each departure.

At a monthly manufacturing quit rate of roughly 1.4% in 2025, a 500-person plant would average about seven quits a month. Track overtime, training hours, and lost production until the replacement reaches full output. Add those costs to recruiting expenses.

Include supervisor time, required qualifications, safety training, scrap, and production interruptions.

What it costs to replace a skilled frontline employee

Deloitte puts the cost of replacing a skilled frontline worker at $10,000 to $40,000. In a UKG survey, most manufacturing HR leaders estimated average replacement costs at $20,000 to $40,000. Replacing an hourly production employee can cost five figures once recruiting, training, overtime, and lost production are included. Positions requiring more skill and experience generally cost more to replace.

Replacement costs depend heavily on the role. Production-line roles often see more departures, and local competition for hourly workers can contribute to turnover. Departures in skilled trades are often lower. This group includes machinists, maintenance technicians, and other skilled employees who keep equipment running. Their specialized skills make replacements harder to recruit, especially when nearby employers compete for the same people. Positions with frequent departures and long training periods can become some of the plant's largest recurring staffing expenses.

Production and line Higher turnover

Production-line roles often see more departures than skilled trades. Include training and the time needed to return to full production when estimating replacement costs. For planning, estimate $10,000 to $25,000 per departure, including overtime coverage and training time. A nearby warehouse or fulfillment job paying $1 to $2 more per hour can be enough to drive these exits.

Skilled trades and maintenance Lower turnover

Estimated turnover is lower, but replacement costs are higher, often $30,000 to $40,000 or more. Recruiting and training can take longer for specialized roles. When an experienced technician leaves, the plant loses valuable equipment knowledge and troubleshooting experience. For a critical maintenance position, downtime alone can exceed the cost of recruiting a replacement.

Shift supervisors and leads Costs vary by role

Replacing a shift supervisor also means rebuilding the routines and team knowledge that person carried. An experienced lead keeps the crew organized, reinforces safety practices, and trains new employees. The departure can interrupt training and affect team stability across the shift.

Calculate turnover costs for your plant

Start with your actual pay rates, overtime, hiring expenses, and training hours. Use the role's fully loaded hourly cost as the starting point for your calculation. Include recruiting and onboarding expenses, overtime hours needed to cover the work, and lost production while the new hire reaches full output. For a production worker earning $22 an hour, the estimated cost often falls between $12,000 and $25,000 per departure, depending on overtime coverage and the time needed to reach full production.

Once you know the cost of one departure, multiply it by the number of departures each year. At annual turnover of 26% to 28%, a 30-person shop would expect about 8 departures a year. At $12,000 to $25,000 per departure, that is roughly $94,000 to $210,000 annually. The low estimate is 30 × 26% × $12,000 = $93,600. The high estimate is 30 × 28% × $25,000 = $210,000. A 500-person plant at the same turnover rate would have substantially more departures and higher annual costs. Use the annual cost to weigh investments in pay, training, onboarding, and supervisor development.

Find opportunities to improve retention

Across industries, Gallup’s 2024 study found that 42% of voluntary leavers believed their manager or organization could have taken action to keep them, down from 52% in its 2019 study. Start with the factors employees experience every day: pay, schedules, onboarding, supervision, and safety. Compare hourly pay with nearby employers. Look at mandatory overtime and scheduling flexibility. Then examine the first 90 days, including training, supervisor check-ins, and opportunities to advance.

Look closely at employees who leave during their first 30 days. UKG reports that about a third of new-hire turnover happens in the first 30 days, before the plant has recovered any of its hiring and training spend. Beyond pay, focus on a structured first 90 days, a clear path above the entry rate, and regular supervisor check-ins. Keeping an experienced employee also keeps valuable production knowledge on the floor and saves another round of recruiting, training, and lost production.

Review turnover alongside production costs

Pull two or three years of monthly departure data and look for seasonal patterns. If departures regularly increase in the weeks after a year-end bonus, schedule reviews, pay adjustments, and career conversations before that period.

Review turnover alongside scrap rates, machine uptime, and other operating measures each month. Overtime hours per worker, turnover percent by shift, and 90-day attrition are workforce measures to review each month. Looking at these measures together helps you see where staffing trends are starting to affect production.
