Microsoft 365 plan comparison tool

What the comparison tool covers

The tool compares 25 Microsoft 365 and Office 365 plans and add-ons across the Business, Office 365, Frontline, Enterprise and Education families, against 485 features, each linked to Microsoft's own documentation. Feature data compiled by ComputeCloud from Microsoft's own documentation, with UK prices added by ComputeCloud. Prices are Microsoft's UK and US list prices, and the number of users you enter turns them into a monthly cost for your whole team.

Microsoft allows up to 300 seats in total across Business Basic, Standard and Premium, so above 300 users the tool shows the Business plans as not available.

The add-on columns (Defender Suite, Purview Suite and their Frontline, Business Premium and Education versions) list only what the add-on itself brings, so a ticked feature that sits in an add-on column needs the base plan plus the add-on. On a computer, Full table is the complete matrix with each plan as a column, and Choose plans adds the add-on suites, Microsoft 365 E7 and the Education plans to it.

Copy link gives you a URL that reopens the page with your ticks and settings, Save selection keeps it in your browser, and Download CSV exports the current view for a spreadsheet. New to the tool? The ? button next to the tabs runs a short tour.

Guides to the plans

If you would rather read than tick, the Microsoft 365 licensing guide explains the plan families with a price table, and there are short comparisons of Business Premium vs Business Standard, Business Premium vs E3 and E3 vs E5, plus a page on what Business Premium costs and a guide to Microsoft 365 backup: what Microsoft keeps, which plans include retention and litigation hold, and what Microsoft 365 Backup costs.

About the prices

Prices are Microsoft's UK and US list prices per user a month on an annual commitment, paid yearly, excluding VAT, for the versions that include Teams. A monthly subscription costs 20% more; every price, with and without Teams, is on the Microsoft 365 pricing page. Prices marked indicative were not on Microsoft's UK price pages when we checked and come from UK resellers; Education plans are priced through education partners. Volume agreements, charity pricing and promotions differ, so treat the figures as a guide and confirm with your licensing partner before you commit. Microsoft reviews the local-currency prices of its cloud services every 1 January, starting on 1 January 2027, and says guidance on that first update will come in November 2026; it hasn't said whether prices in pounds will change (local-currency price reviews). To see what has changed recently, such as the July 2026 price rise and new Copilot plans, the licensing changes log lists every change with its date.

Not sure which plan is right?

Licensing is rarely as simple as the price list. A free assessment from a Microsoft 365 licensing specialist checks what you have today, where you are paying for features nobody uses, and which mix of plans and add-ons covers what you actually need. If you are also retiring on-premises servers, there is a separate free Azure migration assessment covering scope, a ballpark cost and a timeline.
