Free ops AI calculators
Payback months, seat waste from overlapping jobs, and when Make-class automation beats copy-paste. Numbers come from your inputs — we do not store them. Not rankings. Not financial advice.
AI seat payback
Months to earn back a seat from hours saved × fully-loaded hourly cost. Use the result to test your own work estimate.
AI subscription overlap checker
Map one job per tool, inspect overlap and unused seats, then download a renewal CSV. Built for ops and finance, not a directory.
Manual glue vs automation
What copy-paste between apps costs per month — and when a ~$11/mo credit tool pays back.
How to use these
Each tool runs entirely in your browser. Change an input and the result updates. If you cannot name hours saved or a unique job, you do not have a purchase thesis — that is the point.
These calculators are for ops and finance leads who need a number before a renewal — not a listicle of “best AI tools.” Public list prices on this site are dated September 2026; always confirm on the vendor page or your invoice.
Free calculators → AI toolkit spreadsheet ($9) or AI toolkit audit ($19). When you want a durable grid (seats, spend, hours, payback, owner, cancel-by, overlap, decision), use the spreadsheet. When you want a written memo about overlap and fit on your list, use the audit.
Checkout is live via Stripe. After you pay, we email delivery (spreadsheet) or intake next steps (audit). Questions: hello@aiproduct.reviews.
