| Net savings (5 yr) | $185,000 | — |
| ROI (5 yr) | +285% | — |
ABB IRB-6600 has no listed price, so payback can't be computed. Contact the manufacturer for a quote.
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.
