AI vs. Legal Counsel: What Replacement Actually Costs
High salary makes the arithmetic attractive. Professional liability makes the deployment narrow.
These figures come from the DroidWork TCO model for Legal Counsel at mid level, on a base salary of $132,000. The employee figure is fully loaded — benefits, payroll tax, overhead, management time and recruiting amortisation — not base salary. The AI figure sums all seven cost dimensions, not tokens alone.
Where the money actually goes
Token cost is 2.4% of total AI cost for this role. The remaining 97.6% is what standard vendor ROI models omit.
| Cost dimension | Annual |
|---|---|
| Tokens / compute | $5,011 |
| Hosting & infrastructure | $39,800 |
| Security & compliance | $53,500 |
| Process failure & rework | $50,467 |
| Residual human oversight | $48,084 |
| Total AI TCO | $206,705 |
Security, compliance, and silent failure. A missed indemnity clause surfaces during a dispute — years later, at maximum cost.
What AI does well here
Contract review first passes, clause extraction, precedent research, and standard document drafting.
What stays human
Legal advice, privilege, risk judgement, and anything a regulator or court expects a licensed human to stand behind.
The honest verdict
Genuine savings driven by salary, but cap the scope at review assistance. Hallucinated citations have already produced court sanctions.

Can AI replace a lawyer?
No. Unauthorised practice of law rules and professional liability require a licensed human. AI accelerates review and research under supervision.
Why do legal roles show meaningful savings?
Because the salary baseline is high relative to AI infrastructure cost. Savings scale with salary, which is why senior roles model better than junior ones.
What is the biggest documented failure mode?
Fabricated case citations. Multiple jurisdictions have sanctioned filings containing AI-invented precedent, making verification a mandatory, non-optional cost.
