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

MetricARMPR1
InvestmentNo price$50,000
Payback period—12.0 mo
Net savings (5 yr)—$200,000
ROI (5 yr)—+400%

ARM 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.
