AI Meter Map
Every AI meter you pay for, on one sheet, with the source link and the date beside each price.
The free, open-source Copilot prompt library that sits under this work was cited by Jared Spataro (Microsoft, AI at Work) in his 25 February 2026 note. He was citing that free repo when it held 300+ prompts. This is a separate, paid product and he did not review or endorse it.
The situation
Your AI bill has three meters and no owner. Copilot seats and Credits, Mistral tokens, and the ChatGPT seats one team bought on a card. Each vendor counts differently, so nobody can tell you what a task actually costs.
The question that stops the room is not what the licences cost. It is what we are paying per person across all of it, and who owns each line. Most teams cannot answer either one today.
What this is
One workbook that brings the seat, credit and token meters across Microsoft, Mistral and OpenAI into the same place, turns them into cost per task and cost per user per month, and records a named owner on every line. Where a vendor publishes no price, the cell says so instead of guessing, and the totals tell you how many lines they exclude.
What is inside
- A Price Book of 24 meters across Microsoft, Mistral and OpenAI: 21 carry a published list price, 3 do not and are marked not public rather than estimated. Every row has a source link, a last-checked date and a price version, and turns red after 60 days. Room for 32 more of your own.
- A Task Converter with a worked example: summarising a 20-page contract, costed on Mistral Large 3, gpt-6.1-sol and gpt-6-luna, every assumption visible and editable
- Meter Lines, Workload Assumptions, a 12-month Forecast with per-line start and stop dates, Reconciliation against the real invoice, Where is My Usage across 12 admin surfaces, and a Change Log. Nine tabs.
- Two macro-free Excel workbooks, one worked and one blank, openable in Google Sheets
Who it is for
- FinOps and IT finance partners holding an AI line that spans more than one vendor
- Procurement teams going into a renewal who need the per-person number first
- The person who will be asked what a task costs, and cannot answer it from three portals
Who it is not for
- Teams on one vendor with one invoice and no agents. Seats times price is your number and you do not need this yet.
- Anyone wanting usage pulled automatically. In v1 you enter it by hand, and the sheet tells you where to find each number.

Does it tell me what a Copilot task costs?
No, and that is deliberate. Microsoft does not publish credits per action, so that cell reads not costed until you measure it in your own tenant. Copilot is the headline vendor here and the sheet still refuses to invent the number, because a made-up figure in the one cell finance will quote is worse than a blank.
Are the prices going to be stale in a month?
Some will move, which is why every row carries its source link, the date it was checked and a price version, and turns red after 60 days. Prices were last checked 20 October 2026, and you can re-check any number yourself in about a minute, which is the point of shipping the link rather than just the figure.
Does it compare the vendors like for like?
It does not claim to. A Copilot seat is bundled software sold with identity and grounding; tokens are raw model access. They carry different features and different contractual terms, and putting a cost beside each one does not make them equivalent. The sheet says so where it matters.
Is there a team price?
No, because the licence already covers the organisation. $39 licenses one organisation internal use: you, your employees and contractors working under your direction. FinOps, procurement and IT can all work in the same sheet. No seat counting and no team tier.
What is the difference from The Real Cost of Copilot?
That book is the method for one vendor, and gets you to a defensible Copilot total. This is the instrument across three, and it is where you keep the numbers. They are sold separately and work well together.
