BUILT BY SEGMENTUM · COWORK COST GUIDE
How many Copilot Credits does an Excel analysis use?
Building an Excel analysis is medium-to-heavy Cowork work - roughly 400 to 1,200 Copilot Credits, about £3.20 to £9.50 per workbook. The range is wide because "analysis" covers everything from summarising one sheet to assembling a workbook from scattered sources.
What this task adds up to
One person, one task is easy. The monthly picture is what matters - put in how often this actually happens in your business.
Usage only - licences come on top, and every person needs one. Credit ranges are directional; run the task and check /cost in Cowork for your real figure. $0.01 per credit at roughly £1 = $1.27, ex-VAT. Last verified 13 July 2026.
What drives the cost
Where the data starts drives the cost. Numbers already in one clean sheet are cheap to analyse. Numbers spread across exports, emailed attachments and three departments' trackers cost real retrieval before the analysis begins - same output, twice the credits. If a task keeps coming in expensive, that's usually the data's untidiness talking, not the tool's pricing.
The person this page is really about closes the month. A finance manager producing four analyses at month-end - sales summary, aged debt, cost variances, cashflow view - spends £13 to £38 a month on work that used to occupy the best part of a day. Worth saying: Cowork works on spreadsheets it can reach in Microsoft 365. If your numbers live in an accounts platform, export first - or count that time in.
Common questions
Can it work with our accounting system's data?
Only once it's in Microsoft 365 - an exported sheet in OneDrive or SharePoint, yes; inside the accounts platform, no (without connectors).
What kind of analysis can it actually do?
Summaries, comparisons, variance breakdowns, charts and a written narrative of what the numbers show. It's an analyst's first pass - check the workings like you would a junior's.
Why did the same analysis cost different amounts twice?
Probably data shape. Cleaner input, fewer retrieval and correction steps, fewer credits. Untidy data is expensive data.
BEFORE YOU COMMIT
That's the cost. The harder question is whether it's the answer.
A new tool sitting on top of an estate that nobody fully understands usually adds cost, not clarity. So before you commit the budget, it's worth asking a simpler question: is Cowork actually your constraint, or is it something underneath it? We help established UK businesses get a clear view of what they're running - and whether the next bit of spend earns its place.
