# The Real Cost of a Bad Hire in a 30-Person Company

_Salary is the smallest line in the bill. Here is the full arithmetic on a mis-hire in a small company, and the screening layers that catch what a resume hides._

Owners tend to price a bad hire at whatever they paid the person before letting them go. Six months of an $85,000 salary, call it $42,500, painful but survivable.

That number is wrong by a factor of three or four, and the parts it leaves out are the parts that actually hurt.

## The full arithmetic

Take a $85,000 operations manager who does not work out and leaves at month seven.

| Line item | What it is | Typical cost |
|---|---|---|
| Salary and burden | 7 months at $85K plus roughly 25% burden | $62,000 |
| Recruiting the first time | Fee, job posts, or your own hours | $8,000 to $17,000 |
| Onboarding and ramp | The 90 days before anyone is productive | $21,000 |
| Manager time | 4 hours a week from someone senior, for 7 months | $14,000 |
| Team drag | Two people covering gaps and redoing work | $18,000 |
| The empty seat again | 3 months to hire and 3 more to ramp the replacement | $35,000 |
| Work that did not happen | The projects the seat existed to deliver | The largest number here |

Even before that last row, you are at roughly $160,000 to $170,000. On a 30-person company that is real money, and it lands in a single fiscal year.

The last row is the one owners cannot bring themselves to write down. The seat existed because something needed doing. For seven months it did not get done, and for six more it still will not. In a small company that is often a product launch, a market entry, or a system migration pushed a full year.

## Why small companies mis-hire more often

Not for lack of care. For structural reasons that are fixable.

**The job was never defined.** The role gets written the week the pain peaks, so it describes relief rather than an outcome. "Operations manager to help with everything" is not a job, it is a wish. If you cannot name the three things this person owns and the number each one moves, no process will save the hire.

**One person made the call.** In a small company the founder often interviews alone, twice, and decides. No second read, no structured comparison, no scorecard. The candidate who interviews well wins, and interviewing well is a different skill from doing the job.

**Speed pressure.** The seat has been empty for months, the team is drowning, and the third candidate is good enough. Everyone knows this feeling and almost everyone regrets acting on it.

**No reference discipline.** References get skipped or reduced to a formality. The two questions that matter are almost never asked: "What did this person actually own?" and "Would you hire them again, and for what?"

## The screening layers that catch it

A resume tells you where somebody has been. It tells you almost nothing about whether they can do this job, in your company, at your stage. Each layer catches something the one before it misses.

1. **Role alignment before sourcing.** Write the three outcomes and the numbers attached to them. Everything downstream is scored against this, and if you cannot write it, stop here. This is where most searches should pause and usually do not.
2. **Structured screening.** Same questions, same order, every candidate, scored independently. Not because it is fair, though it is, but because it makes candidates comparable. Unstructured interviews mostly measure rapport.
3. **A work sample.** Ninety minutes on a real problem from your business, paid. This single layer catches more mis-hires than every other one combined, because it tests the work rather than the description of the work.
4. **Two on the panel, minimum.** Independent scores written down before anyone discusses. The moment scores are shared first, they converge and you have one opinion wearing two hats.
5. **References that ask real questions.** Not "was she good." Ask what she owned, what she struggled with, what conditions she needs to do her best work, and whether they would hire her again into this specific role.

That structure is close to how [our recruiting process](/recruiting) is built, and the reason it starts with role alignment rather than sourcing is exactly the failure above. A search that begins with resumes is already solving the wrong problem.

## Before you hire at all, check you need a hire

Half the searches that come to us should not be searches. Three tests:

| If the work is | The answer is | Why |
|---|---|---|
| Repeatable and documentable | Support capacity, not a hire | Faster, cheaper, and scales down if you are wrong |
| Senior but not full-time | A fractional executive | You get the judgment without the $300K package |
| Ambiguous and owns an outcome | A real hire | Nothing else covers accountability |

If the work is a checklist, a hire is the expensive answer. [What to delegate first](/insights/what-to-delegate-first-founder-delegation) walks the sequencing, and [virtual assistance](/va) covers the capacity route.

If the seat is senior and the work is real but does not need forty hours, a [fractional executive](/fractional) starts in about two weeks instead of three to six months, and you find out whether the seat was the right idea before committing to a salary. [When a fractional executive beats a full-time hire](/insights/fractional-executive-vs-full-time-hire) covers where that line sits.

## If you are already in one

Most owners know by day 45 and act around day 200. That gap is the expensive part.

Set a written 30, 60 and 90 day expectation on day one, with named outcomes. Review at each mark honestly. If two of the three marks are missed and the reasons are about the person rather than the circumstances, act. Waiting rarely changes the outcome and always raises the bill.

And be honest about which failure it was. If the job was never defined, that is not the candidate's fault, and hiring a second person into the same undefined job produces the same result at the same price.

## The number worth tracking

One metric tells you whether hiring is working: the share of hires still in the seat and meeting their outcomes at twelve months. Below 70% and the problem is your process, not your luck.

## Next step

The cheapest hire you will ever make is the one you scoped properly and screened in layers. The most expensive is the one you made in a hurry because the seat had been empty too long.

If you are about to open a search, book a discovery meeting and we will pressure-test whether the role is defined well enough to hire against, or take the [Founder Bottleneck Assessment](/founder-bottleneck-assessment) to see whether the constraint is really a missing person.
