What is this AI seat’s payback time?
Enter price, seats, and hours you would actually recover if the condition is true. We compute monthly value and payback months. You supply the hours — we do not invent them.

Payback in — months. Now run that across every tool you pay for.
That's one tool. The $9 AI toolkit spreadsheet runs this math on your whole stack.
What the number means
Monthly value = hours/week × 4.33 × hourly cost (rounded). Payback months = monthly cost ÷ monthly value. A short payback does not mean “buy” if hours are fictional — only count hours you would recover when the condition is true.
How to read it: A short payback is worth testing against a real recurring workflow; a longer payback needs stronger evidence; zero recovered hours means there is no case yet. Adjust the thresholds to your finance policy.
Start only when you can name a concrete condition (meetings losing decisions, glue work weekly, etc.). This is not a ranking of “best AI tools.” Prefer invoice spend over list price when you know it.
Operators often under-count recovered hours and over-count “AI might help someday.” Write the condition in one sentence before you trust the result. Finance usually wants cancel-by dates and an owner on the same row — that is what the $9 sheet is for once you outgrow a one-off calculator.
