ROI Comparison
Same operating assumptions across every robot — the only difference is price. Set your numbers once to see which pays back fastest.
Annual labor displaced (per robot): $50,000
| Metric | ARM | Kirobo |
|---|---|---|
| Investment | $500,000 | $393 |
| Payback period | 120.0 mo | < 1 mo |
| Net savings (5 yr) | -$250,000 | $249,607 |
| ROI (5 yr) | -50% | +63491% |
Estimates labor-cost displacement only — not a full total cost of ownership. Actual ROI depends on integration, maintenance, training, downtime, and task fit. Converted currencies are indicative; USD is the price of record.
