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 | Flex 300 pick-assist | S-series sort |
|---|---|---|
| Investment | $36,000 | $7,900 |
| Payback period | 8.6 mo | 1.9 mo |
| Net savings (5 yr) | $214,000 | $242,100 |
| ROI (5 yr) | +594% | +3065% |
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.
