Automation ROI Calculator accuracy and testing

Formula source

• Hours saved equals tasks per month multiplied by minutes saved per task, divided by 60. Gross savings equals hours saved multiplied by hourly cost. Net monthly savings subtracts monthly tool cost. First-year net savings subtracts implementation cost from 12 months of net savings, and ROI compares that first-year net savings to implementation cost.
