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 | A2-W | Digit V4 |
|---|---|---|
| Investment | $145,000 | $250,000 |
| Payback period | 34.8 mo | 60.0 mo |
| Net savings (5 yr) | $105,000 | $0 |
| ROI (5 yr) | +72% | +0% |
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.
