ROI Calculation Logic

Assuming 10 wheelchair users in a care facility requiring 5 lifts/day, this technology could reduce each assist time by 5 minutes. With an estimated caregiver annual labor cost of ~$20K (AI est.), and an hourly wage of ~$12 (AI est.), direct labor savings for 3 caregivers could reach ~$9K/year (AI est.). Including benefits from reduced caregiver turnover and accident insurance, total annual cost savings could reach ~$100K per facility (AI est.).

Speed to Market
