Microsoft 365 Business Premium vs Standard vs Basic: Which Plan Does Your Business Need?
Most businesses pick a Microsoft 365 plan from the price list. Do people need desktop Word and Excel? Then buy the cheapest plan that has them. That gets the productivity part right and skips the part that matters most on a bad day.
This guide breaks down Microsoft 365 Business Basic, Standard, and Premium: what each one includes, why the jump from Standard to Premium is about security and evidence rather than apps, and why we now treat Business Premium as the starting point for most small businesses.
Key Takeaways
- As of July 2026, Business Premium costs $22 per user per month, $8 more than Standard (Microsoft, 2026).
- Basic vs Standard is about apps. Standard vs Premium is about who can sign in, from where, and on what device.
- Without Premium, detailed sign-in logs last only 7 days, and upgrading later won’t bring them back.
Which Microsoft 365 Business Plan Should a Small Business Choose?
In July 2026, Microsoft raised Business Basic to $7 and Business Standard to $14 per user per month, while Business Premium stayed at $22, according to its Microsoft 365 pricing and packaging update. For any business that handles money or client data, Premium should be the default. The cheaper plans are fine as deliberate exceptions.
| Plan | Price (per user/month, annual) | What it adds |
|---|---|---|
| Business Basic | $7 | Email, Teams, OneDrive, SharePoint, web and mobile Office apps |
| Business Standard | $14 | Everything in Basic, plus desktop Office apps |
| Business Premium | $22 | Everything in Standard, plus sign-in controls, device management, and advanced threat protection |
All three plans top out at 300 users. For a small business, the choice is never about size. It’s about what you get.
What’s the Difference Between Business Basic and Business Standard?
The gap between Basic and Standard is $7 per user per month after Microsoft’s 2026 update, and it buys one thing: the installed desktop apps. Basic users work in a browser and on a phone. Standard users get full Word, Excel, and Outlook on their computers. It’s a productivity choice, not a security one.
Basic works for someone who mostly reads email, joins Teams calls, and opens the occasional shared file. Standard fits anyone who lives in spreadsheets or builds real documents all day. That’s most office staff.
The 2026 update did give both plans a little more protection, including checking links when someone clicks them. But identity and device controls still sit one tier up.
What Does Business Premium Add Over Business Standard?
Identity-based attacks rose 32% in the first half of 2025, according to Microsoft’s Microsoft Digital Defense Report 2025. Premium is built around that problem. It uses the same apps as Standard. What you’re paying for is control over who gets into your accounts, from where, and on what device.
Per Microsoft’s Business Premium security FAQ, Premium adds four main pieces:
- Microsoft Entra ID P1 (Conditional Access). Rules about how people sign in, not just whether the password is right. Block sign-ins from other countries, shut off sign-in methods attackers abuse, or only allow company laptops to open company files. It builds on multi-factor authentication instead of replacing it.
- Microsoft Intune. Set security rules on laptops and phones and wipe company data off a lost device. It’s the tool behind mobile device management in most Microsoft offices.
- Defender for Office 365 Plan 1. Opens suspicious attachments in a safe sandbox first and flags emails pretending to be your owner or a vendor.
- Defender for Business. Endpoint protection with detection and response for your computers.
Microsoft 365 Business Premium costs $22 per user per month in 2026 and includes Microsoft Entra ID P1, Intune, Defender for Business, and Defender for Office 365 Plan 1. Business Standard includes none of those. The apps are identical, so the $8 difference pays entirely for identity, device, and threat protection.
Microsoft 365 Log Retention: Why 7 Days Isn’t Enough
The average breach took 241 days to identify and contain in 2025, according to IBM’s Cost of a Data Breach Report. Microsoft 365 Business plans without Premium keep detailed sign-in logs for just 7 days. Well before the average breach is contained, the record of how the attacker got in is gone.
Basic and Standard come with the free tier of Microsoft Entra ID, the system that handles sign-ins. Per Microsoft’s Entra data retention documentation, that tier keeps sign-in and directory audit logs for 7 days. Premium’s Entra ID P1 keeps them for 30 days and lets you export them for longer storage.
To be fair, every business plan includes Microsoft’s unified audit log, which keeps 180 days of activity like mailbox access and file changes. It shows what happened inside an account. The sign-in logs show how someone got into it, and that’s what tells you whether the hole is closed.
We saw this firsthand on an account compromise we worked this fall. An attacker used a phishing trick that got around MFA, then quietly read the mailbox for months.
On the client’s plan, the detailed sign-in logs only covered the last 7 days, so most of the timeline had to be pieced together from the less detailed audit log, and the start of the attack predated even that. We could prove what the attacker did, but never pin down exactly when they first got in.
The trick was device code phishing, a technique Microsoft’s own threat researchers documented in 2025. Microsoft’s guidance is to block that sign-in method with Conditional Access. That’s a Premium feature, so the rule that would have stopped this exact attack was never available.
Here’s the catch: log retention isn’t retroactive. Microsoft’s documentation says so directly. Upgrade today and you get 30 days of history starting now, not the month you needed. If a mailbox takeover like business email compromise worries you, the logs have to be collecting before it happens. (If it already has, start with our guide on what to do after a cyberattack.)
Is Microsoft 365 Business Premium Worth the Cost?
In 2025, Verizon’s Data Breach Investigations Report SMB Snapshot found ransomware in 88% of small and mid-sized business breaches, compared with 39% at larger organizations. When a small business does get breached, ransomware is usually part of it. Next to that, $8 per user per month is cheap. For a 10-person office, Premium costs $960 a year more than Standard.
Compare that to a single incident. The FBI’s 2025 Internet Crime Report counted more than $3 billion in reported business email compromise losses. Even a small case means hours of investigation, password resets, and calls to clients and your bank.
There’s one trap worth naming: paying for Premium and never turning anything on. None of these features configure themselves. A Premium license on default settings is mostly an expensive Standard license, which is why who manages your Microsoft 365 matters as much as which plan you buy.
When Business Basic or Standard Is Still Enough
You can mix Basic, Standard, and Premium licenses in one Microsoft 365 account, so not everyone needs the same plan. A seasonal worker who only needs email on a phone can live on Basic. A shared mailbox or room calendar usually needs no license at all.
The thing to watch: Microsoft licenses Premium’s protections per person. Anyone who handles money, client information, or admin access should be on Premium. Everyone else is a judgment call.

Frequently Asked Questions
Is Microsoft 365 Business Premium worth it for a small business?
For most businesses that handle money or client data, yes. As of July 2026, Premium costs $22 per user per month, $8 more than Standard. That buys sign-in controls, device management, stronger email protection, and 30 days of sign-in logs instead of 7.
What’s the difference between Microsoft 365 Business Basic and Business Standard?
Business Basic ($7 per user per month in 2026) includes email, Teams, OneDrive, SharePoint, and web and mobile Office apps. Business Standard ($14) adds the full desktop apps like Word, Excel, and Outlook. Their security features are nearly identical.
How long does Microsoft 365 keep sign-in logs?
On Business Basic and Standard, Microsoft Entra keeps sign-in and directory audit logs for 7 days. Business Premium includes Entra ID P1, which keeps them for 30 days. All business plans keep the unified audit log, covering mailbox and file activity, for 180 days.
Do I have to migrate anything to upgrade to Business Premium?
No. Moving from Basic or Standard to Premium is a license change in the admin center, and email, files, and settings stay put. Just remember that upgrading only starts the 30-day log window from that day. It doesn’t recover the 7-day logs that already expired.
Does Business Premium replace my antivirus?
It can. Business Premium includes Microsoft Defender for Business, which adds detection and response to endpoint protection. Some businesses run it as their main protection. Others keep a separate endpoint tool and use Premium for its identity and email security.
