| Payback period | 30.2 mo | 12.0 mo |
| Net savings (5 yr) | $124,000 | $200,000 |
| ROI (5 yr) | +98% | +400% |
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.
