ROI Calculation Logic

Operating assistive devices in medical and care facilities faces challenges with labor costs for attachment and adjustment. This technology could reduce attachment time by ~66% (from 10 minutes to 7 minutes per session). Assuming 20 attachment/adjustment operations per day per facility, this saves 60 minutes/day. Over 250 operational days/year, this equates to 250 hours saved annually. At an hourly wage of ~$13.33 (AI est.) (2,000 JPY / 150), this results in ~$3,333/year (AI est.) in savings per facility. Across 50 facilities, the total estimated annual cost reduction is ~$166,650 (AI est.).
