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 DELTA | RONGWIN ER30 6-Axis CNC Robotic Arm |
|---|---|---|
| Investment | $9,900 | $7,800 |
| Payback period | 2.4 mo | 1.9 mo |
| Net savings (5 yr) | $240,100 | $242,200 |
| ROI (5 yr) | +2425% | +3105% |
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.
