Microsoft 365 is a monthly or yearly subscription that gives you access to Office apps, cloud storage, and email

Microsoft 365 (formerly Office 365) bundles Word, Excel, PowerPoint, Outlook, and other tools into a single subscription you pay for regularly instead of buying once. You get the desktop versions of these programs on your computer, plus online versions you can use in a web browser, cloud storage through OneDrive, and email through Outlook. The cost and what's included depends on which plan you choose — there are versions for individuals, families, and businesses.

The subscription renews automatically each month or year depending on what you select at purchase. You can cancel anytime, though you won't get a refund for the time remaining in your current billing period. If you stop paying, you lose access to the apps and your files stay in OneDrive but you can't edit them until you resubscribe.

Key Takeaways

  • Microsoft 365 Personal costs less per month than Microsoft 365 Family but covers only one person; Family covers up to six people on separate accounts.
  • You need an active subscription to use the desktop versions of Word, Excel, and PowerPoint; the web versions are free with a Microsoft account but have fewer features.
  • All plans include 1 TB of OneDrive storage per person, which is where your files live when you save them to the cloud.
  • You can install Microsoft 365 on multiple devices (phone, tablet, computer) but only use it on one device at a time per subscription.

Personal and Family Plans: What's the Difference

Microsoft 365 Personal covers one person on one Microsoft account. You can install the apps on multiple devices — a laptop, desktop, and phone — but you're the only person who can use them. Personal includes 1 TB of OneDrive storage, Outlook email with advanced spam filtering, and access to Microsoft support.

Microsoft 365 Family covers up to six people, each with their own Microsoft account and their own 1 TB of OneDrive storage (so 6 TB total across the family). Each person gets their own copy of Word, Excel, PowerPoint, and the other apps. Family costs more per year than Personal, but when split among multiple people it's cheaper per person. You manage who's on the subscription through your Microsoft account settings, and you can remove or add people anytime.

If you live alone or only one person in your household will use the apps, Personal is the right choice. If two or more people need access, Family is usually the better value even though the upfront cost is higher.

Business Plans: Microsoft 365 for Work

Microsoft offers separate subscriptions for small businesses and enterprises. Microsoft 365 Business Basic includes web and mobile versions of Office apps, email through Outlook, and cloud storage, but not the full desktop versions of Word and Excel. Microsoft 365 Business Standard adds the desktop apps. Microsoft 365 Business Premium includes everything in Standard plus security and device management features.

Business plans are priced per user per month and are meant for companies with employees. They include more storage than personal plans, team collaboration tools like Teams and SharePoint, and admin controls so a manager can oversee multiple accounts. If you're self-employed or a freelancer, Personal or Family is usually what you need; business plans are for organizations with multiple staff members.

What You Actually Get: Apps, Storage, and Email

Every Microsoft 365 subscription includes the core Office apps: Word for documents, Excel for spreadsheets, PowerPoint for presentations, Outlook for email and calendar, OneNote for notes, and Access and Publisher (on some plans). You also get Clipchamp, a video editor, and Designer, an AI tool for creating images and designs. These come as desktop programs you download to your computer and as web versions you use in your browser.

OneDrive cloud storage comes with every plan — 1 TB for personal and family plans, more for business plans. OneDrive is where your files live when you save them to the cloud instead of your computer's hard drive. You can access them from any device, and they sync automatically across your devices. Outlook email is included and works on desktop, web, and phone.

You do not get unlimited storage, unlimited email accounts, or unlimited devices using the subscription at the same time. One subscription covers one person (Personal) or up to six people (Family), and each person can use it on multiple devices but only one at a time.

Free Alternatives: When You Don't Need a Subscription

Microsoft offers free web versions of Word, Excel, PowerPoint, and Outlook through Office.com. You need a free Microsoft account to use them. The web versions have fewer features than the desktop versions — you can't use advanced formulas in Excel, for example, or add complex animations in PowerPoint — but they're real, functional programs and they're genuinely free.

Google Workspace (Docs, Sheets, Slides) and other free tools like LibreOffice are alternatives if you don't want to pay for Microsoft. The choice depends on what you're doing and whether you need the specific features in the desktop versions. If you only write simple documents and spreadsheets, the free web versions of Office might be enough. If you do complex work or need to use advanced features, a subscription pays for itself.

How to Buy and Manage Your Subscription

You buy Microsoft 365 directly from Microsoft's website or through retailers like Amazon and Best Buy. You choose your plan, enter a payment method, and your subscription starts immediately. Microsoft will charge you automatically each month or year depending on what you selected.

You manage your subscription through your Microsoft account settings. You can change your payment method, update your billing address, pause your subscription temporarily, or cancel anytime. If you cancel, you keep access to your files in OneDrive but you can't edit them with the Office apps until you resubscribe. You can also see your subscription status and renewal date in your account.

If you buy through a retailer, you get a product key code that you redeem on Microsoft's website to activate the subscription. The process is the same after that — automatic renewal and management through your account.

Frequently Asked Questions

Can I use the same Microsoft 365 subscription on my laptop and phone?

Yes. You can install Microsoft 365 on multiple devices — laptop, desktop, tablet, phone — but you can only use it actively on one device at a time. If you sign in on your phone, you're signed out on your laptop. This limit applies per subscription, so if you have Family, each of the six people can use their copy on multiple devices.

What happens to my files if I stop paying for Microsoft 365?

Your files stay in OneDrive and you can still view them, but you can't edit them with Word, Excel, or PowerPoint until you resubscribe. You have 60 days after your subscription ends to resubscribe before Microsoft may delete your files, though you can contact support to recover them after that window.

Do I need Microsoft 365 if I only use Word occasionally?

Not necessarily. The free web version of Word at Office.com works for basic documents, letters, and simple formatting. If you need advanced features like tracked changes, complex styles, or offline access, a subscription is worth it. Try the free version first and upgrade if you need more.

Can I share my Family subscription with someone who doesn't live with me?

Technically yes — you can add anyone to your Family subscription and they get their own account and storage. Microsoft's terms say it's for household members, but enforcement is limited. Each person on the subscription can use it on their own devices independently.

Is Microsoft 365 the same as Microsoft Office?

No. Microsoft Office is the one-time purchase version you buy once and own forever (though it doesn't get updates). Microsoft 365 is the subscription version with automatic updates and cloud features. Office is cheaper upfront but doesn't include OneDrive, Outlook email, or the web versions of the apps.
