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 | AlphaBot 2 | K2 Forerunner |
|---|---|---|
| Investment | No price | $60,000 |
| Payback period | — | 14.4 mo |
| Net savings (5 yr) | — | $190,000 |
| ROI (5 yr) | — | +317% |
AlphaBot 2 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.
