FAQ
What ROI formula is used?
ROI % = (gain − cost) ÷ cost × 100. Productivity mode values hours saved × hourly rate as gain.
Is this financial advice?
No. It is a simplified educational calculator—not accounting, tax, or investment advice.
Can ROI be negative?
Yes. If gain is less than cost, net profit and ROI reflect the loss.
What is return multiple?
Gain divided by cost (e.g. 2.5× means gain is 2.5 times the cost).
