The 30 Jun deadline on Microsoft 365 Copilot Business pricing

Bottom line. Microsoft 365 Copilot Business runs $18 per user per month for existing Microsoft 365 Business customers only through 30 Jun 2026, then $21. If your team is already on a Business plan and you have been circling Copilot, the cost-rational move is to decide before the deadline. The discipline is to decide on real usage, not on the deadline itself.

Microsoft made Copilot Business generally available on 2 Dec 2025 at $21 per user per month on annual commitment, for organisations of up to 300 seats. Existing Microsoft 365 Business customers can hold a promotional $18 per user per month, but only through 30 Jun 2026, and only for the first year.

Microsoft’s own framing of what the seat buys is the useful part, because it names the apps:

“For just USD21 per user per month, Copilot Business brings secure, enterprise-grade AI into the Microsoft 365 apps SMBs use every day: Word, Excel, PowerPoint, Outlook, and Teams.”

— Jared Spataro, Chief Marketing Officer, AI at Work, Microsoft, in the 2 Dec 2025 announcement.

The math is small and clear

The difference is $3 per user per month, which is $36 a year per seat, for the first year. For a ten-person team that is a few hundred euros, which is real money for a small business but not a reason to license seats you will not use. The saving is genuine and bounded: it applies to the first year, to the seats you lock in before 30 Jun 2026, and to nothing else.

So the deadline sets the timing, and your usage sets the count. The two are separate decisions, and the common mistake is letting the first one make the second. A discount on a seat that sits idle is a saving on a cost you should not be taking.

Decide seat by seat

Copilot Business pays back on roles that live in Word, Excel, Outlook and Teams through the day and would routinely use drafting, summarising and analysis. It does not pay back on occasional users, no matter how good the rate. The honest move for a small team is to count the heavy-app users, license those before the deadline, and leave the rest at standard pricing until there is evidence they need it.

One caveat worth a moment: the $18 standalone add-on offer is distinct from an earlier, now-expired bundle promotion, so confirm you are pricing the right thing before you commit. The broader question of how Copilot sits next to the other assistants a small team might run is in the Claude Pro versus ChatGPT Plus read, and the discipline of not stacking overlapping subscriptions is the solopreneur stack-consolidation piece. The same cost-versus-usage logic for a bootstrapped team is in the bootstrapped-SaaS AI cost read.

What changes this verdict

Cadence on this piece is 30 days, set to land just after the deadline so the verdict can confirm what actually happened to the price. The three changes that would move it: Microsoft extending the promotional rate past 30 Jun 2026; Microsoft changing the standard price or the 300-seat cap; or a packaging change that folds Copilot into the base Business plans the way the enterprise tiers moved with E7. We re-test on or before 5 Jul 2026; the Holding-up record for OPS-093 carries any change, dated.
