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 | Alpha 1S | AlphaBot 2 |
|---|---|---|
| Investment | $650 | No price |
| Payback period | < 1 mo | — |
| Net savings (5 yr) | $249,350 | — |
| ROI (5 yr) | +38362% | — |
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.
