How much does a bad hire cost?

SHRM Foundation research puts direct replacement costs at 50–60% of an employee's annual salary, with total turnover costs ranging from 90% to 200% of annual salary once lost productivity and supervisor time are counted. For a $60,000 field tech that's roughly $30,000 to $120,000 — and in the trades, callbacks and reputation damage push the top of that range higher.

Why is a bad hire more expensive in the trades?

A bad field tech doesn't just cost wages — they cost botched jobs, callbacks, warranty work, a damaged customer relationship, and the senior tech's time spent supervising or redoing work. Those indirect costs often dwarf the salary.

What's the single biggest hidden cost of a bad hire?

Customer reputation. In the trades, one bad install or rude house call can cost referrals and reviews worth far more than the hire's salary — and that damage doesn't show up on any payroll report.

What does a bad hire actually cost a trades business?

The short answer.

Direct replacement costs run 50–60% of the person's annual salary, and total turnover costs land between 90% and 200% of salary — that's SHRM Foundation research on what it takes to replace someone. For a $60,000 HVAC tech, that's roughly $30,000 to $120,000. In the trades the top of that range is conservative, because a bad field tech damages things an office hire can't.

Here's where that money actually goes.

The direct costs (the ones you can see)

Recruiting and onboarding, twice. Job ads, screening time, paid training — all spent on someone you now have to replace and re-spend on.
Wages for low or negative output. You paid full rate for work that was slow, wrong, or had to be redone.
Separation costs. Final pay, admin time, and the disruption of an unplanned exit.

The indirect costs (the ones that actually hurt)

These rarely get measured, which is why owners underestimate the total:

Botched jobs and callbacks. A bad install means warranty work, a return trip, and parts — on your dime.
Customer reputation. One bad house call can cost referrals and reviews. In a business built on word-of-mouth, that's the most expensive line item of all.
Senior tech drag. Your best people stop billing to babysit, correct, or redo the bad hire's work.
Team morale. A weak or toxic hire makes your good techs work harder and trust you less.

Why the trades multiplier is so steep

In an office, a bad hire produces a bad spreadsheet. In the trades, a bad hire produces an angry customer, a leaking pipe, and a one-star review with your company name on it. The work is customer-facing and physical, so mistakes are visible, expensive, and public.

How to avoid paying it

The cost of a bad hire is really the cost of hiring in a hurry from a thin pool. The fix is structural: screen for fit before you're desperate, and always have a bench so you never have to say yes to the only warm body who applied.

Two numbers make that concrete: skilled-trades roles take about 56 days to fill, and turnover in the trades runs far above most industries — so the pool is thin exactly when you're most desperate. The rest of the picture is in our trades hiring statistics roundup.

That's the entire premise behind how we hire for plumbing and HVAC businesses — pre-screened, culture-fit techs ready before the seat opens, so a replacement hire never becomes a 200%-of-salary event.
