The Hidden Cost of Unfilled Roles—and How to See It Clearly
When Sarah, an HR Manager at a plastics manufacturing facility, glanced at her open assembler requisitions one Monday morning, she felt that familiar tension. Production was behind. Overtime was climbing. Supervisors were frustrated. On paper, she had “just a few” open roles—but in reality, those gaps were affecting nearly every part of the operation. What she didn’t have was a clear way to explain how much those vacancies were costing the business—in real dollars.
For 35 years, First Call has worked alongside HR and hiring managers like Sarah—leaders who understand that open positions impact far more than headcount. They impact productivity, morale, overtime spend, and long-term stability. That’s why we created the Labor Gap Cost Estimator: a practical, transparent tool designed to help HR leaders and hiring managers quantify the real cost of unfilled roles and make confident, data-driven staffing decisions.

Why Labor Gaps Are Harder to Measure Than They Look
Most organizations track vacancies by number. But HR leaders know the real impact runs deeper. When roles remain unfilled, work doesn’t disappear—it shifts. Teams stretch thin. Overtime increases. Productivity slows. Managers step in where they shouldn’t have to. And all of it creates hidden costs that are difficult to quantify during budget reviews or leadership meetings.
The Labor Gap Cost Estimator helps bridge that gap. Using straightforward inputs—such as hourly pay, overtime pressure, and how much work is realistically being covered when a role is unfilled—the estimator calculates the monthly financial impact of labor gaps. It also provides a side-by-side comparison of that impact with the estimated cost of staffing services, helping HR and hiring managers have clearer, data-driven conversations.
Built for HR Leaders, Not Spreadsheets
We know HR managers don’t need another spreadsheet—you need clear numbers you can share with leadership. That’s why the Labor Gap Cost Estimator translates workforce gaps into real dollars, helping quantify monthly vacancy costs and potential staffing savings. This tool was designed to be:
- Realistic – grounded in how work actually gets covered (or doesn’t) when roles are unfilled
- Cost-Focused – estimating the monthly financial impact of vacancies and minimum savings using staffing services
- Consultative – built to support smarter decision-making, not push a one-size-fits-all solution
- Transparent – with a sample scenario and full formula breakdown available for review
“We know unfilled roles don’t just impact numbers—they impact people, teams, and long-term performance. This tool reflects our consultative approach by helping HR leaders understand vacancy costs, uncover potential savings, and make informed decisions that support both their workforce and business goals.”
— Tracy Nice, Owner & CEO, First Call
Turning Insight Into Action
When Sarah ran the Labor Gap Cost Estimator for her facility, the results gave her something she hadn’t had before: clarity. She could finally show leadership how a handful of open roles translated into thousands of dollars in monthly impact from lost productivity and overtime burden. The conversation shifted from “Why are these roles still open?” to “How do we solve this strategically?”
Tools like the Labor Gap Cost Estimator aren’t just calculators—they’re conversation starters. They help HR leaders make informed decisions, protect their teams from burnout, and build long-term workforce solutions.
If you’re navigating open roles, rising overtime, or production strain, we invite you to explore the Labor Gap Cost Estimator and see the true impact for yourself. Because when you can clearly see the cost of the gap, you’re better equipped to close it.
