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 | GSK RMD120 | KR 120 R3900-2 K |
|---|---|---|
| Investment | $43,995 | $51,950 |
| Payback period | 10.6 mo | 12.5 mo |
| Net savings (5 yr) | $206,005 | $198,050 |
| ROI (5 yr) | +468% | +381% |
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.
