AI Agent vs. Human Hire: Two ROI Calculators for Sales Leaders

By September 18, 2026News

The question every sales leader is asking in 2026

Should we hire a human, or deploy an AI agent?

It’s the right question. The wrong way to answer it is with vendor pitch decks and gut feel. So we built two interactive models that put numbers on it.

Agent vs. SDR Calculator

This model puts a full year of an SDR hire — salary, benefits, ramp time, quota attainment — head-to-head with an AI SDR agent, including platform cost, usage, and conversion assumptions.

The headline result from the default model: the AI agent wins by $135.9K in year one, delivering 311% ROI with a 2.9-month payback.

Agent vs. Rep Calculator

This one compares an AI agent in assist-the-team mode against a human account executive.

The headline result from the default model: a +$205K net-value advantage for the assist mode, at 280% ROI with a 3.2-month payback.

Adjustable models, your assumptions

Both calculators are fully adjustable. Team size, salary, quota, and AI cost assumptions are all editable inputs — run the numbers for your team, not ours.

What’s next

More “Agent vs.” calculators are coming: support, CSM, recruiter, RevOps, and account manager.
