The real cost of a bad hire (and how to calculate yours)
A bad hire doesn't just waste a salary. Here is what it actually costs when you factor in lost time, team impact, and starting over.
The number everyone underestimates
Ask a founder what a bad hire costs and they'll say "a few months of salary." The actual number is 2-3x that person's annual salary when you add everything up. For a role paying 60,000, a failed hire costs 120,000-180,000. That's not an exaggeration. Let's break it down.
The direct costs
Recruitment costs
What you paid to find and hire them. Job ad spend: 500-2,000. Recruiter fee (if used): 15-25% of salary, so 9,000-15,000 for a 60,000 role. Internal time spent: hiring manager hours reviewing CVs, interviewing, coordinating. At 20+ hours across the team, that's 2,000-5,000 in lost productivity.
Total recruitment cost: 5,000-20,000 depending on how you hired.
Salary and benefits paid
The average bad hire stays 6 months before it becomes clear it's not working. That's 30,000 in salary plus benefits, taxes, and equipment. Call it 35,000-40,000 all-in.
Severance and offboarding
Depending on the country, termination can cost 1-3 months of salary. In some European markets, more. Legal review, paperwork, and HR time add 2,000-5,000. Budget 10,000-20,000 for the exit.
The hidden costs (where it really adds up)
Lost productivity
A new hire takes 3-6 months to reach full productivity. A bad hire never reaches it. Every month they're underperforming, work isn't getting done — or it's getting done badly and someone else has to redo it.
Estimate the value of what a good hire would have produced in 6 months versus what the bad hire actually produced. The gap is typically 20,000-40,000 in unrealized output.
Manager time
Managing an underperformer is exhausting. Extra 1:1s, coaching sessions, documentation, performance improvement plans. Managers spend 5-10 hours per week on a struggling employee that they'd otherwise spend on productive work. Over 3-4 months, that's 100+ hours of management time.
Team impact
This is the cost nobody calculates but everyone feels. A bad hire drags down the team. Strong performers pick up their slack. Morale drops. Trust in leadership erodes ("why did they hire this person?"). In small teams, one bad hire can cause your best people to leave.
If a top performer quits because they're frustrated by a struggling colleague, add their replacement cost to the bad hire total. Suddenly you're looking at replacing two people, not one.
Opportunity cost
While you're dealing with the bad hire — managing them, eventually terminating them, then re-hiring — you're not doing other things. That sales territory isn't being worked. That product feature isn't being built. That marketing campaign isn't being run. The opportunity cost of 6 months of a vacant-then-failed-then-vacant-again role is enormous.
The math
For a role with a 60,000 salary:
Recruitment: 5,000-20,000. Salary and benefits (6 months): 35,000-40,000. Severance and exit: 10,000-20,000. Lost productivity: 20,000-40,000. Manager time: 10,000-15,000. Re-hiring costs: 5,000-20,000. Opportunity cost: 15,000-30,000.
Total: 100,000-185,000.
That's 1.7x to 3x the annual salary. And this doesn't include the hardest-to-quantify costs: damaged client relationships, missed market opportunities, and the cultural damage of a bad hire in a small team.
How to calculate your specific cost
Use this framework for any role:
1. Hard costs: Recruitment fees + salary paid + severance + re-hiring costs. These are easy to calculate from your records.
2. Productivity loss: Estimate what a successful hire would have produced (revenue generated, features shipped, campaigns run) and subtract what the bad hire actually produced.
3. Time tax: Hours spent by the manager, HR, and team members dealing with the situation, multiplied by their hourly cost.
4. Ripple effects: Did anyone else leave? Did a project get delayed? Did a client relationship suffer? These are harder to quantify but often represent the largest costs.
What this means for how you hire
Knowing the true cost of a bad hire changes how you think about the hiring process.
Spending 2,000 on a better assessment is cheap insurance when a bad hire costs 100,000+. The ROI on a work sample test, a thorough reference check, or an extra interview round is massive.
Using a recruiter at 20% fee for a 60,000 role costs 12,000. If they're good, they reduce your bad hire rate significantly. That 12,000 is nothing compared to the 100,000+ cost of getting it wrong.
Hiring slightly slower is almost always worth it. Taking an extra week to find the right person is better than spending 6 months discovering you hired the wrong one.
The cheapest hire is the one you get right the first time. Everything else is expensive.
