A customer support AI agent handling 1,000 interactions per month can save 108 hours of staff time. After accounting for a $1,500 monthly platform fee and the cost of human review for successful outcomes, the net value delivered to the organization is $4,458 per month.
The true cost of an AI agent includes not just the subscription, but the labor required for escalation and quality checks. In this model, 35% of interactions are escalated to a person, and every accepted outcome still requires two minutes of human review to ensure accuracy.

Escalation, review and rework are part of the true cost of an AI agent. Track them — an agent that resolves fewer tickets with less rework can beat one that closes more tickets badly.
How do we define a successful outcome?
An outcome is only successful if it is accepted without further escalation. If an agent resolves 65% of its 1,000 monthly interactions, it produces 650 successful outcomes. The ROI calculation must account for the time humans spend reviewing these "successful" cases. When each outcome takes 12 minutes of staff time to handle manually, the AI saves significant labor, but the two minutes of human review per case is a necessary deduction from the total time saved.
What is the true cost of an AI interaction?
Calculating the cost of saying "Hi" to an AI agent requires looking past the license fee. By dividing the $1,500 platform cost by the 650 successful outcomes, the base technology cost is roughly $2.31 per resolution. However, the business must also track the cost of the 35% of cases that the AI fails to resolve. High escalation rates or heavy rework requirements can quickly erode the $5,958 in gross labor value that the agent generates.
NetLift measures this value by comparing the time work takes with AI against a verified historical baseline. Rather than relying on self-estimates, we use Evidence Quality grades to verify the $55 loaded staff cost and actual minutes saved. This deterministic approach allows leaders to decide whether to Expand or Improve an implementation based on realized net value, all without using employee surveillance like keystroke logging or screen monitoring.
