Most small contractors know turnover is expensive. They just don't know how expensive. They think about the time spent re-posting the job and doing interviews. They don't think about everything else.
Here's what most people miss when they try to calculate the cost of losing an employee.
SHRM puts the cost of a bad hire at 50 to 200 percent of that employee's annual salary. For a plumber earning $65,000, that's $32,500 to $130,000. For a construction superintendent at $90,000, it's $45,000 to $180,000.
Those numbers feel extreme until you walk through the actual components.
Direct replacement costs. Job postings, recruiting fees if you use a recruiter, background checks, drug testing, onboarding paperwork. These are the obvious ones. For a skilled trades role, direct replacement costs often run $3,000 to $8,000 before the new person starts day one.
Lost productivity during the vacancy. While the role is open, work either doesn't get done or gets distributed to other employees who are already at capacity. If the vacancy lasts six weeks on a $65,000 role, you've lost roughly $7,500 in productive time, before you account for any overtime paid to cover the gap.
The learning curve. A new hire takes time to reach full productivity. For a skilled trade, that can be 60 to 120 days. During that period, you're paying full wages for partial output, and often a senior employee is spending time they don't have getting the new person up to speed.
Customer impact. Technicians leave routes. Foremen leave crews that have to be reorganized. Estimators leave bids that are in progress. Some of that work gets recovered. Some of it doesn't. Customer relationships that took years to build can erode in the gap.
Intangible costs. The morale effect on the team when someone leaves. The signal it sends to your remaining employees about whether this is a company worth staying at. These don't show up on a spreadsheet, but they're real.
If you want to run the math for your specific situation, our Bad Hire Cost Calculator walks through all of these components for any role at your company.
Most corporate turnover cost frameworks were built with office jobs in mind. The trades are different in a few ways that make the cost higher:
The skills aren't replaceable overnight. You can't hire an experienced journeyman plumber or a 10-year construction superintendent from a job board on a Tuesday and have them running at full productivity by Friday. Skilled trades have long ramp-up periods, and the market for experienced people is tight.
Your business is built on relationships. In service businesses especially, the employee who's leaving took something with them: the relationship with the customer, the knowledge of that customer's property, the trust that was built over years of service calls. A new tech has to rebuild that from scratch.
Small team impact is multiplied. At a 40-person company, losing one superintendent affects a much higher percentage of the operation than it would at a 400-person company. The ripple effect is proportionally larger.
Turnover has many causes: bad management, inadequate pay, poor culture, limited growth. But one that most companies overlook is bad hiring in the first place.
When a job post attracts the wrong candidates, one of two things happens. You hire someone who wasn't a good fit and they leave within a year, which starts the whole cycle over. Or you keep the role open too long because none of the applicants are qualified, which compounds the vacancy cost.
A hiring messaging problem looks like a turnover problem. It looks like a labor market problem. But the fix isn't paying more or posting on more job boards. The fix is sending a clearer signal to the right people from the start.
A plumbing company in California filled an open role in 48 hours after rewriting their job post. They'd had the same position open for weeks, working with a recruiter, posting repeatedly. Same pay. Same market. Different message, different result.
A boutique tax firm went from 4 qualified applicants a month to more than 200 after their hiring messaging was rebuilt from the ground up. They hired 12 people. The math on the turnover they avoided, and the productivity they gained, is not small.
The first step is understanding what signal your current job posts are sending. Not what you intended them to say. What candidates are actually reading. We cover the specific hiring challenges for plumbers, HVAC technicians, construction superintendents, construction foremen, construction estimators, HVAC installers, plumbing technicians, roofing foremen, roofing superintendents, landscapers, electricians, and asphalt crews in separate guides.
That's what our free Signal Audit is designed to answer. It takes about 10 minutes and tells you specifically where your hiring message is losing qualified candidates.
