AI vs. Customer Support Agent: What Replacement Actually Costs
The most deployed AI use case in the enterprise — and one of the thinnest margins in our model.
These figures come from the DroidWork TCO model for a Customer Support Agent at mid level, on a base salary of $82,000. 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 3.3% of total AI cost for this role. The remaining 96.7% is what standard vendor ROI models omit.
| Cost dimension | Annual |
|---|---|
| Tokens / compute | $4,869 |
| Hosting & infrastructure | $39,800 |
| Security & compliance | $53,500 |
| Process failure & rework | $11,448 |
| Residual human oversight | $29,984 |
| Total AI TCO | $146,581 |
Concurrency. Support is bursty, and above roughly 50 concurrent sessions, per-token pricing gives way to provisioned throughput with thousands per month in fixed cost.
What AI does well here
Tier-1 tickets, order status, password resets, returns, and FAQ deflection at high volume.
What stays human
Escalations, angry customers, ambiguous edge cases, and retention conversations where a human matters commercially.
The honest verdict
Savings are real but thin per agent, and they depend entirely on deflection rate. Below roughly 60% deflection the economics invert.

How much does AI customer support actually save?
Less than vendors suggest at a single-agent level. Our model shows a narrow margin, because deflection is rarely as high in production as in a demo, and escalations still require staffed humans.
What is the concurrency cliff?
Below roughly 50 concurrent users, per-token pricing works. Above it, providers push provisioned throughput — a fixed monthly commitment that applies whether or not you use it.
When does support automation clearly pay off?
At high ticket volume with genuinely repetitive queries. The economics improve with scale, not with salary.
