Cost of one bad hire

How much does a bad hire cost?

Estimates range from about 30% of the employee's first-year salary for frontline roles (a commonly cited industry estimate) to three or four times salary for senior roles (SHRM-published commentary). The total includes recruitment, onboarding, the salary paid while they were in the role, lost productivity, management time, and the cost of replacing them.

How we calculated this

We take the salary you entered and apply the share of first-year salary that a bad hire at that seniority typically costs, from 30% for a frontline role to 100% for an executive. The share stands in for everything a wrong hire consumes: the recruiting spend, the onboarding, the salary paid for output you did not get, the manager hours, and the cost of hiring again. Change the seniority and the share changes with it; the working, the assumptions and the sources are all below.

Your working
Assumptions
  • The base is first-year base salary. Enter base, not total remuneration. Super and other on-costs are excluded, so the real figure is higher than the one shown.
  • The share of salary lost rises with seniority: 30% frontline, 50% professional, 75% manager, 100% executive. The frontline figure is a commonly cited industry estimate with no traceable primary source, which is why it sits at the conservative end and is labelled an estimate. SHRM commentary puts a senior bad hire at up to three or four times salary; we publish the conservative end at every level.
  • "Cost" bundles recruitment spend, onboarding and training, salary paid while they were in the role, lost output, manager time spent managing and exiting them, and hiring again. It leaves out severance, legal exposure, damage to the team, and the customers who noticed, so it understates the worst cases.
  • No credit is given for partial productivity during their tenure. If they delivered something useful before they left, your number is lower.

What to do about it

A bad hire is rarely a skills failure. The person could do the job on paper; they could not do it in your team, with your manager, at your pace. So the fixes sit before the offer, not after it. These steps are for whoever runs the hiring, whether or not they sign the contract.

1

Put the number in front of the people who own the budget

Take the figure above, multiply it by the hires you regret from the last two years, and put it on the same slide as the recruitment budget. Bad hires get treated as a cost of doing business. Priced this way they are the largest single line in the hiring spend, and the easiest one to cut.

2

Write down what "fit" means for this role before you advertise it

Not the values on the wall. The way the team actually works: how decisions get made, how fast, how much autonomy, how much structure, who they will spend the day with. If you cannot write it down you cannot hire for it, and you will default to whoever interviewed best.

3
Where a tool helps

Measure fit the same way for every candidate

Structured interviews with the same questions scored the same way, plus a validated behavioural or work personality assessment alongside the skills screen. Unstructured "gut feel" interviews are the biggest single source of bad hires and the hardest to defend when the hire goes wrong.

4

Make the hiring manager decide against evidence, not against a memory

Get the fit read, the skills score and the interview scores onto one page before the debrief. The manager still decides. They just decide with the same information the recruiter has, and it is on record when someone asks why the hire was made.

5

Count the fit failures in the last twelve months of exits

Most organisations find more than they expected. That count is your baseline. Re-run this calculator each quarter with the roles you regret and watch the number fall as steps 2 to 4 take hold.

Step 3 is the one
you cannot do by hand.

Compono Hire is an applicant tracking system (ATS) that measures fit before you make the offer. It runs the process side you already expect (job posting, pipeline, interview scheduling, offers) and adds the people insight side most ATSs skip: a validated work personality and culture fit read on every candidate, scored the same way every time and shown next to the skills screen.

That is step 3 done inside the process, not as a separate exercise a busy hiring manager can skip. The bad hire you priced above was a fit failure your current tools could not see coming. This is the tool that sees it.

Common questions

What is the formula for the cost of a bad hire?

Add recruitment cost, onboarding and training, salary paid during their tenure, lost productivity, manager time spent managing and exiting them, any severance, and the cost to re-hire. A quick estimate is a percentage of first-year salary that scales with seniority.

Why do bad hires happen if the candidate had the right skills?

Most bad hires meet the skills requirement but clash with the team, the culture, or the way the role actually works day to day. Hiring on skills alone leaves the fit question unanswered, which is where the cost comes from.

How can you reduce the cost of a bad hire?

Measure fit, not just capability, before you make the offer. Behavioural and culture-fit assessment alongside skills screening lowers the chance of the expensive fit failures that drive most bad-hire costs.
