ReckonBoxAI or a human, and where each wins
This calculator compares the monthly cost of handling interactions with an AI assistant against a human, and finds the break-even volume where the AI takes the lead. At 500 interactions a month, a human at $8 each costs $4,000 while an AI on a $300 platform at $0.60 each costs $600, a $3,400 monthly saving.
The saving is real, but the headline hides the more useful number. What you want to know is the volume at which the choice flips, because below it the human is actually cheaper.
The break-even, in interactions
The break-even is the number of interactions a month at which the AI overtakes the human, found by dividing the AI platform fee by the per-interaction saving. Below it the flat fee is not yet earned back.
Run the numbers. A human handles a conversation for about $8, an AI for $0.60, so each interaction the AI takes saves $7.40. The AI carries a $300 monthly platform fee, so it takes 300 divided by 7.40, about 41 interactions a month, before the AI has paid for that fee. Handle fewer than 41 and the human is the cheaper option; handle more and the AI pulls ahead, further with every extra conversation.
Why the human cost climbs and the AI stays flat
A person can handle only so many conversations an hour, so more volume means more hours or more people, and the cost rises almost in a straight line with the count. An AI answers the thousandth conversation as cheaply as the first, so once past its platform fee, its cost barely moves. Set against grounded 2026 figures from Layer3Labs, the split is stark: at 100 interactions a month the human runs about $800 and the AI $360, but at 10,000 the human is near $80,000 while the AI is about $6,300. That flat line is the entire reason automation wins at scale.
Cost is not capability
A pure cost comparison misses what a human virtual assistant actually does. The AI is strong on routine, repetitive, high-volume interactions, and weak on judgment, empathy, and the tangled edge case that does not fit a pattern. That gap is why hybrids are the norm: the AI takes 70 to 80 percent of the volume and a person handles the rest, running about $900 to $1,700 a month against $3,000 to $4,000 for a full human assistant, per AiScaleLabs. So read the saving above as a ceiling, the number if the AI could do everything, which it cannot. The honest figure is somewhere below it.
Feeding it your numbers
The defaults use round, grounded figures, but your work is not average. A complex support conversation costs a human more than a simple one, and an AI that resolves issues end to end costs more per interaction than one that only deflects. Enter your own per-interaction costs and your real monthly volume, and read both the saving and the break-even. If your volume sits near the break-even, the decision is genuinely close and worth revisiting as you grow; if it is far above, the scaling math has already decided it.
At a thousand interactions a month, the same setup that saves $3,400 at five hundred saves closer to $7,400, which is the point: the case for AI is not a fixed discount, it strengthens with every interaction you add.
Frequently asked questions
Is an AI chatbot cheaper than a human agent? Usually, and the gap widens with volume. A human handles a conversation for about 4 to 12 dollars, while an AI chatbot runs 0.10 to 1.50 dollars, per Layer3Labs 2026 figures. At 500 interactions a month at 8 dollars a human and 0.60 dollars an AI on a 300 dollar platform, the human costs 4,000 dollars and the AI 600, a 3,400 dollar monthly saving. Human cost scales with headcount; the AI stays nearly flat.
What is the break-even volume? The break-even is the number of interactions a month at which the AI overtakes the human, found by dividing the AI platform fee by the difference between the human and AI cost per interaction. With a 300 dollar platform, 8 dollars a human, and 0.60 dollars an AI, that is 300 divided by 7.40, about 41 interactions a month. Below it the human is cheaper, because the platform fee is not yet earned back.
Does the AI actually replace a virtual assistant? Not fully, and this tool compares cost, not capability. An AI handles routine, high-volume, repetitive interactions well, while a human brings judgment, empathy, and the ability to untangle a messy edge case the AI cannot. That is why hybrids are common: the AI takes 70 to 80 percent of the volume and a person handles the rest. Read the saving as the ceiling if the AI could do everything, which it cannot.
How much does a human virtual assistant cost? A human virtual assistant runs about 1,500 to 4,000 dollars a month for part-time to near-full-time work, while an AI virtual assistant is 50 to 300 dollars a month, per AiScaleLabs 2026 figures, roughly 80 to 95 percent less for routine admin. A hybrid of AI plus a part-time human lands around 900 to 1,700 dollars a month. Enter your own per-interaction figures above for a comparison tuned to your work.
Why does the human cost scale and the AI stay flat? A human can handle only so many interactions an hour, so more volume means more hours or more people, and the cost climbs almost in a straight line. An AI answers the thousandth conversation as cheaply as the first, so above the platform fee its cost barely moves. That difference is the whole reason automation wins at scale, and it is why the saving grows as your interaction count rises.
