A bad hire costs between 50% and 200% of that person's annual salary, depending on how senior the role is. The more responsibility the position carries, the higher the cost when it goes wrong. Make five poor hiring decisions in a year, which is not unusual, and you're looking at a significant performance gap between you and a competitor who hires well. None of that ever shows up on a report.
This article breaks down where that money goes, how to calculate what your hiring decisions are actually worth, and what you can do differently.
The problem most businesses don't know they have
When a business wants to buy new software or open a new office, it runs the numbers. Expected cost. Expected return. Risk. Justification.
When the same business needs to fill a role, that rigour often disappears. The pressure is to fill the seat quickly. The measure of success is whether the vacancy closed, not whether the hire is delivering.
That gap costs far more than most businesses realise.
Most organisations track things like headcount, staff turnover, and how long roles take to fill. What they rarely do is connect those numbers to actual financial outcomes. So the cost of poor hiring stays invisible, absorbed into the background, written off as just how things go.
It's worth looking at more carefully.
Where the money goes when a hire goes wrong
Take a role with a $150,000 salary. That role is expected to generate around $400,000 in value per year, through sales, output, decisions, or whatever that position is responsible for.
Now imagine the person hired is only delivering 60% of what you'd expect.
Here's what that costs:
- Output you never get: $400,000 x 40% underperformance = $160,000 lost in year one
- Recruitment: Job ads, agency fees, interview time, typically $30,000 to $50,000
- Empty seat: If the role sits vacant for 60 days, that's roughly $1,818 per day in lost value, around $109,000
- Getting up to speed: A new hire running at half capacity for six months costs about $37,500
Total: anywhere from $150,000 to $346,000. For one hire.
And if that person leaves and you have to start again, those costs grow further.
None of this usually gets attributed to hiring quality. It just gets absorbed. Repeated across five roles in a year, that's a $1 million performance gap, while your turnover report looks perfectly normal.
What a great hire is actually worth
The other side of this is just as important, and almost nobody calculates it.
Same $400,000 role. But this time, the hire is performing at 120% of what you'd expect.
That's an extra $80,000 in value in year one alone. Over three years, the additional return from that single hire is close to $240,000.
The gap between a hire performing at 60% and one performing at 120% is $240,000 per year, in the same role, on the same salary.
Across a team of ten, that difference adds up fast. The gap between a business that hires well and one that doesn't is one of the biggest performance differences there is.
Two businesses. Same size. Very different results.
Picture two businesses in the same industry, with similar headcount and similar turnover rates.
Business A fills roles when they need to. The priority is speed. Decisions are made on gut feel. Success means the vacancy is gone. The cost of a bad hire gets absorbed and forgotten.
Business B treats every hire as a business decision. Before the process starts, they're clear on what the role needs to deliver and over what timeframe. They use a consistent approach to assessing candidates. They track whether hires are generating the return they expected.
Three years in, the results look very different.
Business A has higher turnover, patchier performance, and managers who spend most of their time dealing with problems. Business B has a more stable team, higher output, and managers who are focused on moving things forward.
If Business A makes five more poor hiring decisions per year than Business B, at $150,000 to $250,000 each, the annual performance gap exceeds $1 million. Over five years, that gap shapes the trajectory of both businesses.
Both turnover reports look similar. The results don't.
Why good hiring keeps paying off
Good hiring has a cumulative effect that's worth understanding.
When the right person is in the right role, several things happen. Their output is higher. Their decisions are more consistent. The team works better together. Their manager spends less time fixing problems and more time driving progress.
Each of those things supports the others. Better hires mean less management overhead. Less overhead frees up leadership time. Better leadership helps attract more good people.
That's a real, measurable improvement in what your business gets from every pound or dollar you spend on people.
How to work out what your hiring is actually worth
Most businesses never calculate this. The ones that do tend to outperform those that don't. Here's a simple framework.
Step 1: Set a value for each role
For every role, work out what it should deliver. Revenue, output, decisions made, costs managed, whatever is relevant. A sales role is easy: quota and deal size. For other roles, estimate the value the position creates or protects each year.
Example: a $150,000 role expected to generate $400,000 in annual value.
Step 2: Track whether hires are hitting that mark
Are people in that role delivering what you expected? More? Less? Put a number on it. Not just a feeling, an estimate.
Example: five roles running at 70% of expected output means $400,000 x 30% x 5 = $600,000 in value you're not getting each year.
Step 3: Calculate what the shortfall is costing you
Take the gap between expected and actual performance. Add recruitment, vacancy, and ramp-up costs for any roles that have turned over. Multiply by the number of underperforming or failed hires per year.
Example: five failed hires at $200,000 each = $1,000,000 per year, most of it invisible on the P&L.
Step 4: Work out what better hiring would change
If you could cut your mis-hires in half, what would that be worth? If your average hire performed at 10% higher effectiveness, what would that generate? The difference between where you are now and where you could be is the return on improving your hiring approach.
In most businesses, that number is larger than expected, often seven figures over three years.
What actually makes hiring better
Better hiring is not about spending more on recruitment. It's about making more accurate decisions. That comes down to four things.
Be clear on the role before you start. Many hiring failures are not assessment failures, they are definition failures. If you're not clear on what success looks like in the role, no process will fix that.
Use a consistent approach. Gut feel is unreliable. Structured interviews, where every candidate is asked the same questions and assessed against the same criteria, consistently outperform informal ones. Work samples and skills assessments add further accuracy.
Look at fit, not just ability. Someone can be excellent at their craft and still be wrong for the team, the culture, or the stage the business is at. Both matter.
Measure outcomes. Track how hires perform against what you expected. Over time, patterns emerge, and those patterns tell you where your process is working and where it isn't.
Frequently asked questions
What does "people strategy" actually mean?
It's the approach a business takes to hiring, developing, and keeping its people. That includes how you find and assess candidates, how you onboard them, how you develop them over time, and how you retain the ones worth keeping. A strong people strategy treats all of those as connected parts of a system, not separate HR tasks.
How much does a bad hire really cost?
A commonly cited rule of thumb is 50% to 200% of the role's annual salary, depending on seniority. Entry-level roles tend to sit at the lower end of that range. Senior and leadership roles sit at the higher end, because the cost of underperformance and replacement is greater. When you include the value the business doesn't get while the role is underperforming, the total can be significant.
Why don't businesses measure this?
Mostly because hiring has not traditionally been framed as a financial decision that needs measuring. Capital investments get scrutinised. Hiring decisions often don't. Once you start treating a hire the same way you'd treat any other significant investment, with an expected return and a way of tracking actual performance against it, the measurement follows naturally.
What's the difference between time to hire and quality of hire?
Time to hire is how long it takes to fill a role. Quality of hire is how much value the person you hired actually creates. The two often pull in opposite directions. The faster you hire, the less rigorous the process tends to be. Businesses that prioritise speed over quality consistently underperform those that do the reverse.
Do I need a big HR team to do this?
No. The fundamentals, defining what a role needs to deliver, using a consistent assessment process, and tracking performance over time, can be applied in businesses of any size. The complexity of the system can scale with the size of the business.
How do I start?
Pick your three most important open roles. For each one, write down what that person needs to deliver in their first year for the hire to be considered a success. That's your baseline. From there, you can build a simple process around it, consistent interview questions, clear assessment criteria, and a way of checking in on performance at three, six, and twelve months.
The bottom line
Most businesses accept that some hires won't work out. That's true. But accepting it without measuring the cost or trying to improve the hit rate is expensive.
The businesses that treat hiring as seriously as any other major financial decision get better results. Not because they have bigger budgets, but because they make better decisions with the same budget.
Hiring well is a business issue, not just an HR one. And the return on getting it right is significant.
