    1

    Choose the right plan

    ~20s
    Go to microsoft.com/microsoft-365 to compare plans. Microsoft 365 Personal (~$70/year) is for one person. Microsoft 365 Family (~$100/year) covers up to 6 people. If you only need browser-based apps and extra cloud storage, Microsoft 365 Basic (~$20/year) is the most affordable option.

    Quick Tip

    Microsoft often runs discounts at Costco, Best Buy, and Amazon. Check those before buying directly from Microsoft.

    2

    Sign in or create a Microsoft account

    ~15s
    Go to account.microsoft.com. If you use Outlook.com or Hotmail, you already have a Microsoft account — sign in with that email. If not, click "Create a Microsoft account" and follow the steps. It is free to create.
    3

    Install the apps on your computer

    ~20s
    After subscribing, sign in at office.com and click "Install apps" in the top-right corner. Choose "Microsoft 365 apps" and run the installer. It will add Word, Excel, PowerPoint, Outlook, OneNote, and OneDrive to your PC or Mac.

    Warning

    The download is around 4GB and may take 15–30 minutes on a typical home internet connection. Keep your computer plugged in during installation.

    4

    Set up OneDrive for automatic backup

    ~15s
    Once installed, OneDrive appears as a folder on your computer (Windows) or in your menu bar (Mac). Move your Documents and Pictures folders into OneDrive, and they will sync to the cloud automatically. You can access them at onedrive.live.com from any browser.

    Microsoft 365 is a subscription service from Microsoft that gives you access to familiar programs like Word, Excel, PowerPoint, and Outlook, along with 1 terabyte of OneDrive cloud storage. It replaced what used to be called "Microsoft Office," and the key difference is that with 365, your apps always stay updated automatically.

    There are a few ways to buy Microsoft 365. Microsoft 365 Personal costs around $70 per year and covers one person on up to 5 devices. Microsoft 365 Family costs around $100 per year and covers up to 6 people — great for households. If you only need the basic web versions and 100GB of cloud storage, Microsoft 365 Basic is around $20 per year.

    Microsoft also offers free versions. Go to office.com and sign in with a free Microsoft account to use Word, Excel, PowerPoint, and OneNote in your browser at no cost. These web versions work well for everyday tasks but have fewer features than the full downloaded apps.

    To get the downloaded versions, buy a Microsoft 365 subscription at microsoft.com, sign in with your Microsoft account, and click "Install apps." The installer will walk you through adding Word, Excel, PowerPoint, Outlook, and others to your PC or Mac.

    OneDrive is one of the biggest benefits. Your documents automatically save to the cloud, which means you can open them on your phone, a different computer, or share them with someone else. OneDrive comes as a folder on your computer — anything you drop into it syncs automatically.

    The Word, Excel, and PowerPoint mobile apps are free on iPhone and Android for basic use. This means you can view and make small edits to documents on your phone without a subscription.

    If you have an older version of Microsoft Office that you bought as a one-time purchase (like Office 2016 or Office 2019), it will still work but will not receive new features. Switching to a 365 subscription keeps you current and adds the cloud benefits.
