Microsoft 365 Business Premium vs Standard vs Basic

Microsoft 365 Business Standard is a productivity plan: email, Teams, 1 TB of OneDrive, and the desktop Office apps. Business Premium is the same plan plus a security and device management layer: Intune, Defender for Business, Entra ID P1, and Purview data protection. As of September 2026 the list price gap is $8 per user per month on an annual commitment ($14 versus $22). Business Basic, at $7, drops the desktop apps.

The rest of this guide covers the full price table, exactly what Premium adds, the 300 user cap, and a plain way to decide.

How Much Does Each Plan Cost in September 2026?

These are Microsoft’s US list prices per user per month, taken from the Microsoft 365 business plans and pricing page as of September 2026, for the versions that include Teams.

	Business Basic	Business Standard	Business Premium
Annual commitment (paid yearly)	$7.00	$14.00	$22.00
Monthly commitment	$8.40	$16.80	$26.40
Cost per user per year (annual)	$84	$168	$264

Three things to know about these numbers:

• They changed on July 1, 2026. Microsoft raised Basic from $6.00 to $7.00 and Standard from $12.50 to $14.00, and left Premium at $22.00. The change is documented in Microsoft’s 2026 packaging and pricing update. Existing subscriptions move to the new price at renewal.
• Monthly commitment costs 20 percent more. You can cancel a monthly subscription at any time, and you pay for that flexibility. An annual commitment is cheaper but locks the license count for the term.
• The real upgrade figure is $8, not a round guess. Standard to Premium is $22.00 minus $14.00, so $8.00 per user per month on annual commitment, or $9.60 on monthly commitment. For a ten person office that is $80 a month, or $960 a year.

Microsoft also sells versions without Teams (Basic at $5.40, Standard at $10.79, Premium at $18.79 on the same licensing page). Those only make sense if you are certain you will never use Teams for chat or meetings.

What Do All Three Plans Include?

Every plan includes business email on your own domain through Exchange Online, a 100 GB primary mailbox, 1 TB of OneDrive storage per user, SharePoint team sites, Teams chat and meetings, spam and malware filtering, and Copilot Chat, Microsoft’s web-grounded AI chat, at no extra cost.

The July 2026 update also added URL time-of-click protection to Basic and Standard. That means links in email are checked when someone clicks them, not only when the message arrives.

Business Basic vs Standard: What Is the Difference?

The main difference is the desktop apps.

• Basic includes only the web and mobile versions of Word, Excel, PowerPoint, and Outlook.
• Standard adds the installed desktop apps on up to five PCs or Macs, five tablets, and five phones per user. It also adds webinar hosting in Teams and a few extras such as Clipchamp and Loop.

Basic suits people who live in email and a browser: a front desk, a warehouse lead, a part-time bookkeeper using a web accounting tool. Anyone who builds real spreadsheets, works with long Word documents, or needs Outlook on the desktop should be on Standard or higher.

What Exactly Does Business Premium Add?

Premium includes everything in Standard, plus the following. Each item below is confirmed on Microsoft’s plan comparison table.

Feature	Basic	Standard	Premium
Desktop Office apps	No	Yes	Yes
Microsoft Entra ID	Free tier	Free tier	P1
Conditional Access policies	No	No	Yes
Microsoft Intune (Plan 1)	No	No	Yes
Microsoft Defender for Business	No	No	Yes
Microsoft Defender for Office 365	Time-of-click URL check only	Time-of-click URL check only	Plan 1
Purview Information Protection (sensitivity labels)	No	No	Yes
Purview Data Loss Prevention	No	No	Yes, for email and files
Archive mailbox	50 GB	50 GB	1.5 TB
Windows 11 Pro upgrade rights	No	No	Yes
Maximum users	300	300	300

Here is what those names mean in practice.

Microsoft Intune

Intune is device management. It lets an administrator require disk encryption and a screen lock, push apps and updates, keep company data separate from personal data on a phone, and wipe company data from a lost or stolen device. We cover it in more depth in our guide to Microsoft Intune for small business.

Microsoft Defender for Business

Defender for Business is endpoint protection for Windows, macOS, iOS, and Android. Beyond antivirus, it includes endpoint detection and response, which means it watches for suspicious behavior and lets an administrator investigate and isolate a device. Microsoft describes it as designed for organizations with up to 300 users. It is also sold on its own at $3.00 per user per month, which matters for the decision guide below. See our Defender for Business overview for what it covers.

Microsoft Entra ID P1 and Conditional Access

Entra ID is the sign-in system behind Microsoft 365. Standard includes the free tier, which supports multi-factor authentication through a setting called security defaults. Premium includes Entra ID P1, which unlocks Conditional Access: rules such as “only allow sign-in from a managed device” or “block sign-ins from outside the United States.” Microsoft confirms that Business Premium customers can use Conditional Access. We explain the policies worth having in Conditional Access for small business.

Microsoft Purview Features

Purview is Microsoft’s data protection family. Premium includes two parts of it. Sensitivity labels let you mark a document “Confidential” and have encryption and access rules travel with the file. Data Loss Prevention (DLP) can warn or block when someone tries to email or share content that matches a pattern, such as a Social Security number or a card number. More detail is in our Microsoft Purview guide.

Defender for Office 365 Plan 1

This adds Safe Attachments (attachments are opened in a sandbox before delivery), Safe Links, and stronger anti-phishing policies that look for impersonation of your own people and domain.

What Is the 300 User Cap?

All three Business plans are limited to 300 users each. Microsoft’s pricing table lists “1–300 employees” for every Business plan. If you expect to grow past that, the next step is the Enterprise family (Microsoft 365 E3 and E5), which has no such cap and is priced higher.

For almost every small office this limit is academic. It matters mainly because a few add-ons, such as Microsoft 365 Copilot Business, carry the same 300 seat limit.

Which Plan Should You Choose?

Your situation	Reasonable choice
Staff who only need email, Teams, and web apps	Basic
Staff who need desktop Excel, Word, or Outlook, with no regulated data and company-owned PCs that stay in the office	Standard
Anyone who signs in from a laptop, a home PC, or a personal phone	Premium
You hold health, financial, legal, or other regulated records	Premium
A cyber insurance application or a customer security questionnaire asks about device management, endpoint detection and response, or Conditional Access	Premium
You already pay separately for endpoint protection and device management	Compare that total against the $8 gap

You can mix plans in one organization. A common pattern is Basic for a shared front-desk role, Standard for most staff, and Premium for owners, finance, and anyone mobile. One caution: security features are licensed per user, so everyone a Conditional Access or Intune policy applies to needs a Premium license. Mixing works best when the split is clean.

The Math on Standard Plus Add-Ons

Standard plus standalone Defender for Business is $14.00 plus $3.00, so $17.00 per user. For $5.00 more, Premium also includes Intune, Entra ID P1, Defender for Office 365 Plan 1, and the Purview features. If you need two or more of those, Premium is usually the simpler and cheaper route.

When Do You Not Need Premium?

Standard is a sound choice when all of these are true:

• Everyone works on company-owned computers that stay in the office.
• Nobody reads work email on a personal phone, or you accept that risk knowingly.
• You do not store regulated or highly sensitive records in Microsoft 365.
• Multi-factor authentication is turned on for every account (this is available on every plan and is the single most valuable setting; see why multi-factor authentication matters).

Paying for Premium and never configuring it is the worse outcome. The license does nothing on its own.

Common Mistakes

• Buying Premium and leaving it at defaults. Intune, Defender for Business, and Conditional Access all need setup: devices enrolled, policies written, and a test that a wipe and a block actually work.
• Choosing monthly commitment by accident. It costs 20 percent more. Use it on purpose, for seasonal or short-term staff.
• Licensing shared mailboxes. A shared mailbox under 50 GB generally does not need its own license. Check before you pay for one.
• Forgetting the renewal date. On an annual commitment, you can add licenses any time, but you can only reduce the count at renewal.

How Do You Check Which Plan You Have?

1. Sign in at admin.microsoft.com with an administrator account.
2. Go to Billing, then Your products. Each subscription is listed by name, with the license count and renewal date.
3. Go to Billing, then Licenses to see how many licenses are assigned and how many are sitting unused.
4. To change plans, Microsoft documents the steps in Upgrade or change to a different Microsoft 365 for business plan.

Common Questions

Is Business Premium worth the extra $8 per user?

If staff use laptops, work from home, or read work email on personal phones, usually yes, because Premium is the only Business plan that can manage those devices and restrict sign-ins. If everyone works on office desktops and you hold no regulated data, Standard with multi-factor authentication turned on is a reasonable position.

Can we mix Business Standard and Business Premium licenses?

Yes. Microsoft lets you assign different plans to different users in the same organization. Keep in mind that Premium security features only cover users who hold a Premium license, so a policy that should apply to everyone requires Premium for everyone.

Can we upgrade in the middle of an annual term?

Yes. You can move users to a higher plan during the term, and Microsoft documents the upgrade path in the admin center. Moving down to a cheaper plan generally has to wait until renewal on an annual commitment.

Does Business Premium include Copilot?

It includes Copilot Chat, the web-grounded chat experience, like every Business plan. The full Microsoft 365 Copilot that works inside Word, Excel, Outlook, and Teams with your company data is a paid add-on. We break down the options in Microsoft 365 Copilot for small business.

What happens if we grow past 300 users?

You would move some or all users to Enterprise plans such as Microsoft 365 E3 or E5. Business and Enterprise licenses can coexist in one organization, so the change does not have to happen all at once.

How Coastal Growth Co. Can Help

We can review which Microsoft 365 licenses you hold, which are unused, and whether the plan matches how your staff actually work. If Premium is the right fit, we can set up Intune, Defender for Business, and Conditional Access so the features you pay for are switched on. Details are on our Microsoft 365 and cloud services page, and you can contact us to talk it through. Scope and price are agreed before any paid work.
