A plant runs on a schedule, and turnover is the thing that breaks it. The bill is not the job ad. It is the empty station, the overtime to cover it, the slower line while a new hire ramps, and the safety risk that climbs when a crew is short or green. Here is the plant-floor benchmark the data supports, how far it swings by role, and the part worth sitting with: most of it was preventable.
Manufacturing turnover runs higher than almost any office-based industry. Recent BLS JOLTS data and industry surveys put the sector around 26 to 28 percent a year, with production-line roles often 30 to 38 percent and skilled trades lower at 10 to 16 percent. Replacing a single skilled frontline worker commonly costs $10,000 to $40,000 once recruiting, onboarding, training, lost output, and the overtime to cover the gap are counted. Those are honest planning ranges, not dollar-exact figures, and the right number for your plant depends on the role, the shift, and how completely you count the costs below.
In an office, a vacant seat is mostly lost productivity. On a plant floor, a vacant station is a scheduling problem with a cost attached to every shift it stays open. The line still has to run, so the hours move somewhere: overtime for the workers who stay, a temp who needs supervision, or a slower rate while the spot sits empty. Each of those carries a real number, and none of them shows up as a recruiting expense.
That is why a plant feels turnover faster than a headcount report suggests. A monthly manufacturing quit rate of roughly 1.4 percent sounds small until you apply it to a 500-person facility, where it works out to about seven people leaving every month, every month, as a standing condition. For a manager running lean crews, that is a constant backfill cycle, and the cost lives in overtime, training time, and the production the line did not make while it was short or green.
The other plant-specific cost is safety. A short crew runs harder, and a new hire who has not built the muscle memory of the job is more likely to get hurt or to make a mistake that stops the line. The departure that looks like a $15-an-hour replacement can become a recordable injury, a scrap run, or a missed shipment. Counting only the recruiting cost misses the part that actually hurts.
The most-cited manufacturing figure comes from Deloitte, which puts the cost of replacing a skilled frontline worker at $10,000 to $40,000. A UKG survey of manufacturing HR leaders landed in the same place, with most naming $20,000 to $40,000 as the average. The two agree on the shape: even an hourly production role, refilled and retrained, costs five figures once the full cycle is counted, and the number climbs with skill.
Turnover rates follow the same gradient. Production-line roles, the easiest to leave for a logistics or fulfillment job paying a dollar more, churn at 30 to 38 percent a year. Skilled trades, machinists, maintenance techs, and the people who keep the equipment running, churn far less at 10 to 16 percent, because they are harder to replace and harder to poach. Where the cost bites hardest is the overlap: a high-churn role that also takes weeks to ramp to full rate.
Highest churn on the floor. Fast to fill on paper, but each exit still runs $10,000 to $25,000 once overtime backfill and ramp-to-rate are counted. A $1 to $2 hourly gap against a nearby warehouse or fulfillment job routinely drives these exits.
Lower churn, higher cost per exit, often $30,000 to $40,000 or more. Long to recruit, long to ramp, and they take equipment know-how and troubleshooting history out the door. A single unplanned maintenance gap can cost more than the recruiting bill.
The most expensive floor departure. A good lead holds a crew together, runs the safety routine, and trains the new people. Losing one raises churn beneath them, so the cost compounds across the whole shift, not just the one seat.
Borrowed ranges are a starting point. The figure that moves a budget conversation is the one built from your plant’s own pay, churn, and overtime. The build is simple: take the loaded hourly cost of the role, add the recruiting and onboarding spend, add the overtime hours the gap forces onto the rest of the crew, and add the lost production while the new hire ramps to full rate. For a production worker at $22 an hour, that math commonly lands between $12,000 and $25,000 a departure once the overtime and ramp are honest.
Multiply by your monthly exits and the standing cost becomes visible. At industry-average turnover, a 30-person shop loses roughly $160,000 to $270,000 a year to churn. A 500-person plant at the same rate loses multiples of that. The point of the number is not precision to the dollar. It is to make the preventable share large enough that someone decides to act on it.
Across industries, employees themselves say a large share of voluntary exits, around 42 percent in recent surveys and about half in Gallup’s work, could have been prevented. On a plant floor the preventable causes are unusually concrete: a $1 to $2 wage gap against the logistics job down the road, mandatory overtime with no say in the schedule, a first 90 days with no real onboarding, and safety concerns that get raised and ignored. Nearly a third of manufacturing workers say safety is the area where they feel most ignored.
The early-tenure window is where the leverage is. About a third of new-hire turnover happens in the first month, before the plant has recovered any of its hiring and training spend. A structured first 90 days, a clear path off the entry rate, and a supervisor who runs a real check-in routine move that number more than a one-time pay bump does. The cheapest worker to keep is the one you already trained.
Manufacturing churn is seasonal and predictable. Q1 is the highest-risk window: workers who stayed through the holidays for a year-end bonus start looking in January. Plants that front-load retention in December and January, with reviews, pay adjustments, and career conversations before the spike, lose fewer people than plants that react after the schedule is already short.
Treating turnover as a standing operating cost, tracked like scrap rate or machine uptime, is what separates plants that manage it from plants that scramble. Overtime hours per worker, turnover percent by shift, and 90-day attrition are workforce KPIs worth watching every month, because they move before the production number does.

Sub-industry rate bands (production 30–38 percent, skilled trades 10–16 percent) and per-departure cost splits are directional benchmarks modeled from the JOLTS series and manufacturing workforce surveys above. Treat them as planning ranges and calibrate against your plant’s role mix, shift model, and local wage competition. These figures move; the date each was checked is shown above.
About 26 to 28 percent a year as of 2025 BLS JOLTS data and industry surveys, above the all-industry average of roughly 20 to 22 percent. Production-line roles run higher, around 30 to 38 percent, while skilled trades sit lower at 10 to 16 percent. Your plant’s rate depends on its role mix, shift model, and local wage competition.
Deloitte puts the cost of replacing a skilled frontline worker at $10,000 to $40,000, and a UKG survey of HR leaders landed on $20,000 to $40,000. For an entry production role the figure sits near the bottom of that range once recruiting, onboarding, overtime backfill, and ramp-to-rate are counted; for a skilled trade or maintenance tech it runs toward the top.
For entry and semi-skilled roles the switching cost is low: a $1 to $2 hourly difference against a warehouse, fulfillment, or logistics job routinely drives exits. Mandatory overtime, no say in the schedule, a weak first 90 days, and ignored safety concerns are the other common drivers. Most of these are preventable, which is where the retention leverage sits.

The first 90 days of any new hire is the other high-risk window.
