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 | KR 20 R1810-2 | RP4 |
|---|---|---|
| Investment | $32,900 | $25,000 |
| Payback period | 7.9 mo | 6.0 mo |
| Net savings (5 yr) | $217,100 | $225,000 |
| ROI (5 yr) | +660% | +900% |
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.
