"How much does a bad hire cost?" is a common question, and you'll find many confident figures online. Most come from other countries, other industries, or surveys that are hard to verify.
So instead of quoting a number, here's a way to calculate the cost for your own organisation, which is far more useful.
What counts as a bad hire?
A hire who:
- leaves or is let go within the first year,
- stays but consistently underperforms,
- damages team morale, customer relationships or culture.
The third kind is often the most expensive, and the hardest to see on a spreadsheet.
A simple worksheet
Estimate each line for one typical mis-hire in a role you hire often.
Direct costs
- Recruitment: job ads, agency fees, recruiter time, assessment costs.
- Interview time: number of interviewers × hours × their hourly cost.
- Onboarding and training: trainer time, materials, induction programmes.
- Salary and benefits paid while the person was underperforming.
- Exit costs: notice period, settlements, administrative time.
- Re-hiring: all of the above, again.
Hidden costs
- Lost productivity: work not done, or done poorly, during their tenure and the vacancy afterwards.
- Manager time: extra supervision, performance conversations, fixing mistakes.
- Team impact: colleagues covering gaps, lower morale, and sometimes good people leaving.
- Customer impact: lost deals, complaints, damaged relationships.
- Opportunity cost: the right person you could have hired instead.
Add these up honestly. For many organisations, the result is well above the person's annual salary for managerial roles, and significant even for junior ones. Your own number is the one that should guide your hiring budget.
Why bad hires happen
- Unclear role definition: hiring for a vague "good candidate" rather than specific competencies.
- Over-reliance on unstructured interviews: different interviewers, different questions, gut feel.
- Hiring for skills, ignoring behaviour: someone can do the task but can't work with the team.
- Rushing to fill a seat.
- Not checking fit with the manager, team and culture.
- Confusing confidence with competence.
Practical ways to reduce mis-hires
- Define the role in competencies. List the 5–8 behaviours and abilities that matter most. See our competency mapping guide.
- Use structured interviews, with the same core questions for every candidate and clear scoring. Research shows structured interviews are among the strongest predictors of job performance. (Sackett et al., 2022)
- Add a well-built assessment that covers personality, reasoning and competencies, and use it to focus the interview.
- Ask behaviour-based questions ("Tell me about a time when…"). See behavioural event interviews.
- Involve the actual manager and a peer.
- Check references with specific questions, not "Was he good?"
- Onboard well. Some "bad hires" are really good hires with poor onboarding.
- Review your mis-hires. Every six months, look at who didn't work out, and why.
Where Future Path helps
Our talent assessment produces a hiring recommendation (Strong Hire, Hire, Borderline or Not Recommended), a 17-competency profile, and an interview guide mapped to each candidate's gaps, so your interviewers spend their time on what matters. After hiring, the same report gives managers a 30/90-day development plan, which helps new hires settle faster.
