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 | Cassie | Simon |
|---|---|---|
| Investment | $300,000 | $500,000 |
| Payback period | 72.0 mo | 120.0 mo |
| Net savings (5 yr) | -$50,000 | -$250,000 |
| ROI (5 yr) | -17% | -50% |
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.
