Frequently asked questions
How is annual savings calculated?
Hours saved per year × loaded hourly rate. Hourly rate is average salary ÷ (productive weeks × 37.5 hours).
What is the recommended investment range?
About 3–9 months of projected monthly savings — a practical band for a first pilot before you commit to a larger programme.
How is ROI estimated?
Year-1 net (annual savings minus investment) ÷ investment. If you leave build cost at 0, we use the mid-point of the recommended range.
What should I validate before funding a build?
Confirm the hours are truly repetitive, data is accessible, and a human reviewer owns exceptions — then stress-test a conservative automation %.
Is this the same as ChatGPT or an AI subscription cost?
No. It estimates labour hours unlocked by automating repetitive work — not token or SaaS fees. Add licence costs in the optional build field if you have them.
