The Real Cost of a Bad Hire (Time, Money, and Hidden Damage)

Why mis-hires cost more than you think — and how proof-based hiring prevents them.

Everyone knows bad hires are expensive.

But most business owners dramatically underestimate how expensive.

Because the salary is just the beginning.

The visible costs

These are the numbers you can actually track:

Industry research suggests the average bad hire costs 30% of the employee's annual salary. For a $40,000/year position, that's $12,000 gone.

But that's just what you can measure.

The invisible costs

These are the costs that don't show up on a spreadsheet:

Customer impact

A bad server loses tables. A bad barber loses clients. A bad technician causes callbacks. Every customer interaction with a poor performer is a risk to your reputation.

Team morale

Your good employees have to cover for the bad ones. They get frustrated. They burn out. Sometimes they leave — and now you've lost two people instead of one.

Your time

Every hour you spend managing performance issues, having "difficult conversations," or fixing mistakes is an hour you're not growing your business.

Opportunity cost

While you're dealing with a bad hire, you're not training your best people, serving customers, or finding good candidates.

The math nobody does

Let's say you hire someone at $15/hour. They work for 6 weeks before you realize it's not working out.

Total: $5,600 - $7,400 for a $15/hour position that lasted 6 weeks.

That's a month of full-time wages... wasted.

Why this keeps happening

The hiring process is designed for guessing:

  • Read a résumé (filtered by keywords, not skill)
  • Conduct an interview (tests talking, not working)
  • Hope for the best
  • When you hire based on claims instead of proof, bad hires are inevitable. It's not a people problem — it's a process problem.

    How to fix it

    The solution isn't more interviews or better "gut feelings."

    The solution is proof before the hire.

    When hiring starts with evidence, mis-hires become rare.

    Because you're not guessing anymore.
