The fee and the salary are the part everyone already counts. The months in which the role was not being done are the part nobody does, and they are usually larger.
The cost of a bad hire is the total loss created when a person is hired for a role and the role does not move forward. In a small company, it includes recruitment work, paid ramp, management attention, team drag, delayed output, exit work and the restart of the hiring process.
An interactive calculator: enter salary, recruitment fee, months before the person left, ramp time and time to replace them, in USD, SGD, HKD or INR. It separates the costs that reach a spreadsheet from the ones that never do.
A recruitment fee is tidy. It arrives as one invoice. The real cost of a bad hire is not tidy. It sits in calendars, delayed work, repeated explanations and the role that still has no reliable owner.
A small company hires because something is stuck. A founder is still carrying customer success. Operations is doing finance at night. Sales has no follow-up system. If the new joiner cannot own the work, the company has paid for motion and kept the old bottleneck.
The order matters. Cash is not always the first loss. The first loss is usually time.
A 20-person software company hires its first dedicated customer success lead. The founder expects three things: renewals owned by someone else, fewer support escalations to the founder and a clean route for customer evidence into product. The CV is relevant. The interviews are orderly. The offer is made.
The cost starts before the person joins. Support is still founder-led while the company searches. After the start date, colleagues explain accounts, product gaps and customer history. The new hire is busy, but the renewal process is not built. The support inbox still returns to whoever is least busy. By the time the mismatch is accepted, the role has been filled on paper and unfilled in practice.
The calculator on this page produces the amounts from the reader’s own inputs. The breakdown below names what each amount is made of, in the order the cost usually lands.
| Stage | Cost component | What the amount is made of |
|---|---|---|
| Role approved, no owner yet | Vacancy gap | Time the work is uncovered, senior cover during that period and the value of work that waits. |
| Search under way | Internal selection time | Founder, manager and team hours spent writing the brief, reading CVs, interviewing and comparing evidence. |
| Search under way | External hiring spend | Adverts, recruiter work, reference checks, background checks and any tools used to run the search. |
| Person starts | Onboarding | Equipment, software access, payroll administration, account setup, context documents and colleague explanation time. |
| Early employment | Paid ramp | Salary and employer costs for the part of employment before the person carries the role independently. |
| Mismatch appears | Management attention | Extra reviews, extra check-ins, repeated explanations, corrected work, joined calls and decisions about what to do next. |
| Team adapts | Team drag | Colleague cover, extra meetings, repaired handoffs, slower decisions and time spent working around the gap. |
| Function stalls | Missed output | The renewal process not built, the support backlog not reduced, the feedback route not cleaned up or the promised project not delivered. |
| Decision point | Correction and exit | Coaching, performance conversations, documentation, notice, handover, offboarding and account closure. |
| Role opens again | Restart | A new brief, another search, renewed interview time, a fresh vacancy gap, another onboarding period and another ramp. |
In this example, the founder still attends renewal calls. Product still gets customer evidence through fragments. Customer success still has no clear owner. The cost of a bad hire is not that one candidate was imperfect. It is that the company did not get the function it hired for.
Payroll and recruiter invoices make the loss feel financial. Founders often undercount management attention because no invoice arrives. But a manager’s calendar is a budget. If the founder spends the week reviewing work that should have been owned, the company has paid with attention it cannot spend twice.
It should be treated as an estimate. It cannot know the quality of the handover, the difficulty of the market, the manager’s tolerance for ambiguity or the morale effect on a small team. It is still useful. It puts visible and hidden costs on the same page. It helps a founder test assumptions, compare scenarios and decide where better evidence is worth collecting before the next offer.
HyperPersonal AI adds structure before the offer. CV Cat structures every candidate’s CV into the same columns. Big Five Test lets a candidate take the full IPIP-300 a few questions a day on iPhone. The organisational portal reads the candidate against a role the company has defined.
The personality data uses the public-domain IPIP-300 item pool. Scores are continuous dimensions, never types or categories. A candidate shares a profile only by an explicit, revocable grant. The output does not tell you who to hire, who to reject or who will clash. Decision support, never automated decisions. A human makes the decision.

A cost figure read once and forgotten changes nothing. The point is what a manager does differently on Tuesday, before the next offer is made.

It is the combined cost of a hiring decision that leaves the role short of the work it was meant to own. Count the search, the ramp, management attention, team cover, delayed output, exit work and the restart.
Because the fee is only the visible part. The larger damage in a small company is often the months when the function did not move and senior people kept covering it.
No. It is an estimate based on the assumptions the reader brings. Its use is to make those assumptions explicit and to show which parts of the hiring failure are usually ignored.
No. A mis-hire can come from a vague role, weak evidence, poor onboarding, a changing business or a mismatch between the person and the work. The point is to improve the next decision, not to assign blame.
No. The output is decision support and a human makes the decision. It gives structured evidence and questions for interviews, references and work samples.
The candidate controls it. An organisation sees the profile only through an explicit, revocable grant, so access is not automatic or permanent.
