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 | Core | RB5-850E |
|---|---|---|
| Investment | $39,500 | $22,000 |
| Payback period | 9.5 mo | 5.3 mo |
| Net savings (5 yr) | $210,500 | $228,000 |
| ROI (5 yr) | +533% | +1036% |
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.
