Your CFO wants a number.
Not “this hire didn’t work out.” Not “we had some performance issues.” A number, the kind that justifies a budget conversation about how you hire leaders before the next wrong one is already in the seat.
Here it is. And it’s significantly larger than most HR leaders expect.
Why Leadership Hires Are A Different Category Of Risk
Every bad hire is expensive. A bad leadership hire is expensive in ways that compound through the organisation in real time.
A poor individual contributor affects their own output. A poor leader affects their team’s output, their team’s retention, and their team’s daily experience of work — which then affects the team next to them, and the one after that.
Gallup’s 2025 State of the Global Workplace report introduced a number that should sit in every South African HR director’s budget presentation: 70% of the variance in team engagement is directly attributable to the manager. Not culture. Not perks. Not strategy. The manager.
And here’s what makes this locally significant: Sub-Saharan Africa, the region South Africa sits in, has one of the lowest employee engagement rates globally, with only 19% of employees engaged at work. Gallup also reports that 63% are not engaged and 18% are actively disengaged. The context your new leader steps into is already fragile. A poor hire doesn’t just underperform. They accelerate the departure of team members who were already disengaged. .
That’s the stakes before you’ve spent a rand.
The Full Cost Model — In Rand
Let’s work through a realistic scenario: a mid-to-senior leadership hire with a total cost-to-company package of R900,000 per annum. Not a C-suite executive. A department head, senior manager, or functional lead — the kind of role most organisations fill multiple times a year and almost never cost-model properly.
Line item 1: Recruitment fees — R198,000 to R396,000
Data from APSO, the professional body of the SA recruitment industry, puts the average fee charged by agencies at around 17% of annual salary for standard roles, rising to 25% or more for senior and specialised positions.
At 22% of R900,000: R198,000 — paid whether the hire works or not.
If the hire fails after 90 days (beyond most rebate windows), and you go back to market, that fee is spent twice: R396,000 in recruitment fees alone.
Line item 2: Salary during exit and vacancy gap — R262,500
Notice periods for senior roles in South Africa typically run one to three months by contract. During a managed exit, you are paying full salary for work that isn’t being done at any acceptable standard. At R75,000 per month, a two-month managed exit costs R150,000 before legal consultation if the separation is contested.
Then there’s the gap — the period between exit and a new hire starting. A conservative six-week vacancy at the same rate adds R112,500.
Line item 3: Onboarding and ramp-up — R180,000 (twice)
Oxford Economics found it takes an average of 28 weeks for a new employee to reach full productivity. For a leadership role with wider scope and stakeholder complexity, the window is longer. A leader operating at 65% capacity during ramp-up on a R900,000 package represents approximately R180,000 in lost productive output before they’re functioning at the level you hired for.
When the hire fails, you absorb this twice.
Second ramp-up cost: R180,000.
Line item 4: Team impact — the number most organisations never calculate
This is where the budget conversation usually ends. It shouldn’t, because this is where the largest cost lives.
Gallup’s 2025 data shows manager engagement fell from 30% to 27% in one year — the steepest single-year decline recorded — with the drop most severe among managers under 35 and female managers. The cascade effect is documented: when managers disengage, their teams follow. When teams disengage, they leave or they stay and underperform — both of which cost money.
The calculation most organisations skip: a team of eight people, two of whom exit within 12 months of a leadership change they didn’t believe in, at an average salary of R500,000 each. SHRM estimates that replacing employees in leadership-adjacent roles costs 90% to 200% of their annual salary. At the conservative end, that’s R450,000 per person — R900,000 in secondary turnover cost from a single poor leadership hire.
And that’s before you account for the output of the six who stayed but disengaged.
Gallup’s data shows disengaged employees produce at roughly 60% of their capacity. Six employees at R500,000 each, performing at 60% instead of 100%, represents R600,000 in lost annual output — invisible because it never shows up as a line item, but real because those targets weren’t hit, that work wasn’t done, those customers weren’t properly served.
The Total — And What It Doesn’t Include
| Cost line | Conservative estimate |
|---|---|
| Recruitment fees (x2) | R396,000 |
| Salary during exit + vacancy | R262,500 |
| Ramp-up productivity loss (x2) | R360,000 |
| Secondary team turnover (2 exits) | R900,000 |
| Team disengagement output loss | R600,000 |
| Total | R2,518,500 |
This doesn’t include legal fees if the exit is contested. It doesn’t include client relationships managed by a failing leader. It doesn’t include the reputational signal sent to your talent market when leadership instability becomes visible externally. And it doesn’t include the most expensive cost of all — your best team members leaving not because of salary, but because staying under poor leadership became untenable.
Employees don’t leave organisations. They leave managers. Gallup’s research is unambiguous on this: manager quality is the single largest driver of team-level engagement, accounting for 70% of the variance. Every figure above follows directly from that fact.
Why This Keeps Happening
The obvious question: if the cost is this clear, why do organisations keep making expensive leadership hiring mistakes?
Because the tools most organisations use to make leadership hiring decisions were never designed to predict leadership performance. CVs, references, and unstructured interviews measure the past — what someone has done, where they’ve been, and how well they present under the artificial pressure of an interview.
Schmidt and Hunter’s meta-analysis of 85 years of personnel selection research found that work experience and education have correlations of 0.18 and 0.10 with job performance respectively — yet these are the primary criteria organisations use to build leadership shortlists.
The gap between what most hiring processes measure and what actually predicts leadership success isn’t a minor inefficiency. It’s where R2.5 million goes.
What Changes When You Hire With Data
The organisations that consistently avoid this cost profile don’t have better instincts. They have better data, gathered earlier.
Lumenii’s leadership assessment tools measure the four variables that research consistently identifies as predictive of leadership success: cognitive ability, personality profile, learning agility, and motivational fit. These aren’t abstract psychological concepts — they’re the measurable precursors to whether someone can delegate effectively, develop others, handle ambiguity, and lead a team through change without losing them.
The competency-based assessment platform maps each candidate against a custom profile built from a library of 45 competencies — giving hiring teams a fit score anchored in the specific demands of the role, not a generic idea of leadership quality.
The entire process runs online. Reports are automated. And on Lumenii’s fixed-cost platform, the per-assessment cost for a leadership hire is a fraction of what a single failed hire costs.
The question a CFO needs to answer is simple: is a R2.5 million risk worth running without the data that could significantly reduce it?
Most organisations don’t calculate the cost of a bad leadership hire until they’re already inside one. By then the recruitment fee is spent, the team is disrupted, your best people are updating their CVs, and the conversation with the CFO is about damage control.
The business case for getting this right is strongest before the next hire is made.
