Put a number on the decision before a vendor does it for you.

Nine models covering downtime, support cost, automation savings and first-year return. Each one publishes its formula and its assumptions on the page, so the output is something your finance team can argue with rather than a figure from a vendor's slide. Each row below states which category it serves and how many inputs it asks for.

The numbers are an input to the decision, not the decision. Pair them with category research for deployment fit and a head-to-head comparison for where two finalists actually differ.

What these are for, and what they are not

Every model here takes inputs an IT team can estimate in a few minutes — headcount, ticket volume, outage hours, current licence spend — because a calculator that needs finance-grade assumptions arrives too late to change which vendors get a demo slot.

None of them produces a forecast. They produce the arithmetic behind a claim, with the assumptions visible, so a number you take into a procurement meeting is one you can defend line by line when somebody disagrees with it.
