Question 1

How much does an AI employee cost compared to a human?

Accepted Answer

It depends entirely on scope. A single well-scoped automation typically runs $500-$1,500/month (light complexity), a multi-step workflow with custom integration runs $1,500-$4,000/month (moderate), and a multi-agent system with ongoing tuning runs $4,000-$10,000/month (complex) - typical ranges based on our engagements, not a fixed quote. Compare that against the proportional slice of a fully loaded human salary (salary plus roughly 30% benefits overhead) for the hours that specific task actually takes, not the whole role's salary.

Question 2

Is this calculator saying AI replaces the job?

Accepted Answer

No. This calculator prices only the hours you mark as automatable, out of a 40-hour week. Most roles keep meaningful human-only work: judgment calls, ambiguous specs, stakeholder negotiation, and accountability for what ships. AI augments a role's routine, well-specified tasks; it rarely replaces the role outright. The results include an honest note on what AI genuinely handles well versus what still needs a human for the specific role you selected.

Question 3

Where do the salary numbers come from?

Accepted Answer

The base salary benchmark reuses the same US-market data as our Staffing Model Calculator, which is directionally consistent with the ranges published in our AI Engineer Salary Guide (synthesized from Levels.fyi, Glassdoor, payscale, and the 2025 Stack Overflow Developer Survey). Regional multipliers (UK, EU, India, APAC) are directional cost-of-labor adjustments, not precise per-country figures - edit the region to see how the comparison shifts.

Question 4

What is the AI setup cost for?

Accepted Answer

It is the one-time integration cost: connecting the agent to your systems, prompt/context engineering, and initial monitoring setup, before the ongoing monthly cost kicks in. It is the AI-side equivalent of a human's recruiting and onboarding cost. Light automation typically runs about $1,500 to set up, moderate about $4,000, complex multi-agent work about $12,000 - again, typical based on our engagements, not a fixed quote.

Question 5

What does the break-even month actually mean here?

Accepted Answer

It is the month the one-time AI setup cost is paid back by the monthly savings versus the proportional human cost for that task. If the AI's monthly cost is not actually lower than the human-proportional cost (which happens at low automatable-hours or high complexity), there is no break-even month, since the ongoing cost never nets out ahead.

Question 6

Why does the human cost only count part of a salary?

Accepted Answer

Because the comparison is task-for-task, not role-for-role. If an engineer spends 15 of 40 hours a week on work an agent could do, the fair comparison is the AI's cost against 15/40 of that engineer's fully loaded monthly salary, not their entire paycheck. The other 25 hours are unaffected by this decision either way.
