What's the cost of a bad sales hire — fully loaded?

$240K–$480K per bad AE, fully loaded — and that's the median outcome, not the worst case. A bad hire identified in Month 1 typically isn't terminated until Month 5–6 (Bridge Group 2025 SDR/AE benchmarks: 5.3 month average ramp, ~6.4 month median time-to-PIP-conclusion). You burn 6+ months of runway, contaminate pipeline, and pay a recruiting fee twice. The real cost is not the salary — it's the opportunity cost of the territory sitting vacant or worse, mismanaged.

The Direct Cost Stack (Month 0 to Month 6)

The Indirect Cost Stack (The Real Killer)

• Territory opportunity cost. Bessemer State of the Cloud 2026 reports a Year-1 quota of $1.0M–$1.4M for mid-market AEs. A bad rep typically delivers 25–40% of plan. The delta — $600K–$900K of unbooked ARR — is the real bill. At a 6x ARR multiple, that's $3.6M–$5.4M of enterprise value foregone if the territory is strategic.
• Manager distraction tax. Gartner CSO research pegs manager time on a single underperformer at 18–24% for 12+ weeks. At a $220K loaded VP/Director cost, that is $9.5K–$12.6K of management time alone — not counting the deals they fail to coach on the rest of the team.
• Pipeline contamination. Bad reps mis-stage deals (forecast slop), over-promise on scoping (CS escalation later), and leave bad voicemails with strategic accounts. Plan on 8–14 polluted opportunities at $30K–$60K average ACV; 30–40% are unrecoverable. Direct write-down: $90K–$280K.
• Team contagion. Pavilion's 2025 attrition data shows tenured reps are 2.3x more likely to leave in the 90 days following a visible bad-hire retention (the "why is this person still here" signal). One additional turnover = $35K–$70K layered cost.
• Replacement cycle. Re-recruiting fee + re-onboarding + a second 5-month ramp at 0–40% productivity = $90K–$140K. You pay the ramp tax twice.

Indirect subtotal: $225K–$500K+ depending on territory strategic value and team size.

Three Scenarios

• Best case (low-leverage SDR territory, fast PIP, no team turnover): $240K
• Median case (mid-market AE, 5-month PIP, 8 polluted deals): $340K
• Worst case (named-account AE, 6 months, top rep quits, lost flagship deal): $480K–$700K

The 8x Rule (and Why CFOs Underprice This)

Most finance models treat bad hires as a salary problem. They are a revenue problem. The clean math:

> Bad-hire cost ≈ 1.0× direct comp + 2.0× quota-of-rep + 0.5× manager bandwidth

A rep on $250K OTE with a $1.2M quota = $250K + $2.4M (at 100% pipeline credit) + $25K = $2.67M maximum exposure. Even discounting quota at 60% (assume some recovered by team) you're at $1.7M. The conservative $300K–$420K number is just the *cash* burn — not the *value* burn. See q100 magic-number math for why every dollar of unbooked ARR compounds at the SaaS multiple.

Bear Case: The Counter-Argument You Should Take Seriously

"A 'bad hire' is often a bad onboarding / territory / manager — and firing fast just resets the same dysfunction with a new face." This is the strongest critique and it's frequently right:

• Selection bias. When a startup CRO publicly fires a Month-5 rep, they almost always blame the rep. But the Sales Hacker / Bridge Group 2025 ramp study found 41% of "failed" reps hit quota at their next company within 12 months. Translation: nearly half the time, you fired a fixable problem and paid $300K to learn nothing.
• Territory whitespace. A "bad rep" assigned to a dead territory will look identical to a great rep in the same seat. If the *previous* AE in that geo also failed, the seat is the bug, not the human. See q40 win-rate diagnosis.
• The "fire fast" culture cost. Aggressive PIP cycles correlate with elevated voluntary attrition in the *rest* of the team — the "I'm next" effect. Pavilion 2025 cites a 1.6x voluntary-quit lift in teams with >20% involuntary turnover. So your "save" by firing in Month 4 vs Month 6 may cost you a B+ rep who left in Month 7.
• Hiring-replacement parity is a myth. The implicit assumption ("the next hire will be better") is unsupported. Gartner CSO data shows replacement-hire performance is statistically indistinguishable from the original cohort in 6 of 9 studied SaaS segments. You may just be paying $300K to roll the dice again. See q26 first-hire sourcing and q27 flameout signals before you start the second cycle.

The honest read: fully-loaded cost is real, but 30–50% of it is structural cost you'll pay again on the next hire unless you fix the hiring filter, the territory, or the manager. The cheapest dollar in sales hiring is the one spent on a 4-hour panel before the offer, not the one spent on severance.

When To Pull The Trigger

• Month 1–2: Onboarding. Measure leading indicators only (calls, demos booked, MEDDPICC fluency). Do NOT measure pipeline.
• Month 3: First quantitative gate. <40% of activity bar OR no qualified opps = formal coaching plan, not PIP.
• Month 4: PIP decision. Document specific revenue/activity targets. 30–60 days.
• Month 5–6: Terminate or retain. Standard severance: 2–4 weeks. State-specific WARN considerations apply for >50-rep teams.

See q29 firing timing for the full month-by-month playbook and q30 toxic-star edge case for when this math inverts.

The Forcing Function

Spend 8 weeks recruiting + 2 weeks of interview loops to avoid a $340K median burn. That's 10 weeks of front-loaded rigor against a 6-month back-loaded loss. The ratio is roughly 14:1 in your favor for every additional hour of pre-hire diligence. The CROs who internalize this are the ones whose ramp curves look like step functions, not staircases.
