| Net savings (5 yr) | — | $198,050 |
| ROI (5 yr) | — | +381% |
ABB IRB 1200 5/0.9 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.
