Human worker: ~$28,000 annual cost (minimum wage + benefits in developed markets)
On paper, the payback period is under 12 months. Buy the robot, and within a year you’ve recovered your investment versus hiring a human.
That’s the theoretical case. Reality is more complicated.
The Efficiency Gap
Tesla’s currently deployed Optimus units are operating at less than half the efficiency of human workers when moving batteries in Tesla factories.
That’s in Tesla’s own facilities, doing tasks specifically designed for the robots, with Tesla’s engineering team optimizing the workflow.
Half efficiency means the real payback period doubles—to 2-4 years at current capability levels. That’s still viable for many applications, but it’s a different business case than “replace workers immediately.”
Cost Parity Approaching
The curves are converging. Bain & Company analysis shows the economics shifting:
Unitree’s $16,000 robot already matches the annual cost of US minimum wage
Between 2022-2024, humanoid unit costs dropped 40%
Over the same period, EU labor costs rose 5%
Robot costs declining at ~15-20% annually while labor costs increase at ~3-5% annually creates an inevitable intersection point.
The Target Market
Physical tasks comprise over half of working hours for approximately 40% of the US workforce: drivers, construction workers, warehouse workers, cooks, healthcare aides.
This is the addressable market for humanoid labor substitution. Not every job—but a substantial portion of physical work that’s currently done by humans.
The Realistic Timeline
The intersection point—where robots become economically compelling for most physical tasks—appears to be in the late 2020s to early 2030s.
This assumes continued progress on both cost reduction and capability improvement. Neither is guaranteed, but both have clear engineering paths.
What This Means
The labor economics of humanoid robots aren’t science fiction. They’re straightforward business math that’s approaching viability.
The question isn’t whether robots will be economically competitive with human workers. The question is when—and for which tasks first.
Warehouse work, manufacturing assembly, and repetitive physical tasks are the likely first wave. More complex work requiring adaptation and judgment comes later, as capabilities improve.
The payback math is the skeleton key. When robots cost less than workers and perform at acceptable efficiency, adoption accelerates. We’re approaching that threshold.
