Key Takeaways
- •Proactively track 'cost per hire' by source and 'time to fill' to optimize your recruiting budget and minimize costly vacancies, potentially by leveraging specialized staffing partners.
- •Regularly analyze 'turnover rate' (distinguishing voluntary from involuntary) and 'retention rate' by department or shift to identify and address underlying issues affecting workforce stability and investment returns.
- •Monitor 'overtime percentage' and 'absenteeism rate' across your operations to pinpoint scheduling inefficiencies, understaffing, or employee disengagement, enabling targeted interventions to control labor costs.
10 Workforce Cost Metrics Manufacturers Should Track
Labor is likely the largest line item on your manufacturing budget, and most operations only look closely at it after costs have already spiraled. The right metrics catch staffing leaks while they’re still small. Doherty Staffing Solutions helps manufacturing employers identify which workforce cost metrics reveal problems early, and what to do about each one before it hits your bottom line. This article breaks down 10 metrics that manufacturing operations and HR leaders should track. Each one connects directly to staffing and recruiting costs, giving you a clearer picture of where money is going and where you can reclaim it.
Quick Guide: 10 Workforce Cost Metrics for Manufacturers
- Cost per hire: What it actually costs you to fill one manufacturing role.
- Time to fill: How many days a seat sits open, and what that costs in overtime.
- Turnover rate: The percentage of workers walking out the door, and why.
- Retention rate: The flip side of turnover, and where your investments are paying off.
- Quality of hire: Whether new workers actually perform, not just show up cheap.
- Overtime percentage: How much of your labor spend is going to time-and-a-half.
- Absenteeism rate: Unplanned absences as a share of scheduled work time.
- Contingent labor ratio: How much of your workforce is temporary/contract versus direct.
- Training cost per worker: What it costs to get a new hire fully productive.
- Revenue per employee: Whether your workforce is scaling efficiently with growth.
How We Selected These Metrics
Doherty Staffing Solutions has partnered with manufacturers across the Upper Midwest for more than four decades. The metrics below reflect what actually moves the needle on workforce cost, based on:
- Bill rate, time-to-fill, and vendor performance data tracked daily through various technology platforms across manufacturing clients.
- On-site program experience, where our employment experts see firsthand which cost drivers show up first on the production floor.
- Industry benchmarking research, including Talroo’s HR metrics research, which puts average manufacturing cost per hire at roughly $5,611.
10 Metrics Manufacturers Should Track to Control Workforce Costs
1. Cost per hire
Cost per hire measures the total amount spent to fill a single position, including advertising, agency fees, recruiter time, and onboarding expenses. For manufacturing roles, this number often runs higher than other industries due to safety training, background checks, and shift-specific requirements. According to Talroo’s HR metrics research, the average cost per hire for manufacturing jobs sits around $5,611. Track this metric by position type and hiring source. You may find that referrals deliver lower cost per hire than job boards, or that certain roles consistently exceed budget.
2. Time to fill
Time to fill tracks the number of days between opening a requisition and a candidate accepting an offer. Extended vacancies create ripple effects: overtime for existing workers, missed production targets, and rushed hiring decisions that lead to poor fits. Manufacturing employers can reduce time to fill by building relationships with light industrial staffing partners who maintain ready talent pools. A shorter hiring timeline means less overtime expense and faster production ramp-up.
3. Turnover rate
Turnover rate calculates the percentage of workers who leave during a specific period. High turnover signals problems with job fit, compensation, management, or working conditions, and each departure triggers recruiting, onboarding, and training costs that compound quickly. Separate voluntary turnover from involuntary turnover to understand what you can control. If workers are leaving on their own, exit interviews can reveal patterns. If you are letting workers go, examine your screening and temp-to-hire processes for gaps.
4. Retention rate
Retention rate is the inverse of turnover: the percentage of workers who stay with your organization over a given period. This metric shows whether your investments in training, benefits, and workplace culture are paying off. Track retention by shift, department, and tenure band. You may find that third-shift workers leave at higher rates than first-shift, or that most departures happen in the first 90 days. These patterns point to specific interventions that can improve workforce stability.
5. Quality of hire
Quality of hire measures how well new workers perform against expectations. This includes productivity rates, attendance records, safety incidents, and manager satisfaction scores. A low-cost hire who underperforms costs more in the long run than a higher-cost hire who delivers results. Define benchmarks specific to your operation. For machine operators, that might mean reaching full productivity in eight weeks with zero safety violations. Tracking quality of hire by source helps you direct recruiting spend toward channels that deliver workers who succeed.
6. Overtime percentage
Overtime percentage shows how much of your total labor spend goes to time-and-a-half wages. Some overtime is expected during seasonal peaks or special projects. Chronic overtime often indicates understaffing, poor scheduling, or high absenteeism that forces coverage gaps. Calculate overtime percentage by dividing overtime hours by total hours worked, then multiplying by 100. Compare this number across shifts and departments. On-site workforce management programs can help you anticipate coverage needs and reduce unplanned overtime.
7. Absenteeism rate
Absenteeism rate tracks unplanned absences as a percentage of total scheduled work time. High absenteeism creates production disruptions, forces overtime, and strains team morale. It often signals burnout, disengagement, or workplace issues that need attention. Break absenteeism data down by shift, day of week, and worker tenure. Patterns often emerge: Monday absences may indicate weekend scheduling conflicts, while high rates among newer workers may point to onboarding gaps. Addressing root causes is more effective than punitive policies.
8. Contingent labor ratio
Contingent labor ratio measures the percentage of your workforce made up of temporary, contract, or agency workers versus direct employees. This ratio affects flexibility, labor costs, and compliance exposure. Too few contingent workers limits your ability to scale; too many may indicate reliance on short-term fixes. Track contingent labor costs separately from direct labor costs. Include bill rates, agency fees, and any administrative overhead. A vendor management system gives you visibility into contingent labor spend across multiple staffing suppliers.
9. Training cost per worker
Training cost per worker calculates how much you invest in preparing each new hire for their role. This includes orientation time, safety certifications, equipment training, and mentorship hours. When turnover is high, training costs multiply as you repeat the process with replacement workers. Reducing training cost per worker often means improving retention so you are not repeating the same investments. Talent acquisition partners who screen for job fit and cultural alignment help ensure training investments stick with workers who stay.
10. Revenue per employee
Revenue per employee divides total revenue by headcount to show workforce productivity at a high level. While this metric alone does not reveal staffing inefficiencies, tracking it over time shows whether your workforce is scaling efficiently with business growth. Declining revenue per employee may signal overstaffing, productivity issues, or the need for process improvements. Combine this metric with others on this list to build a complete picture of workforce cost efficiency.
