Office 2021 Home and Business for Mac: one-time purchase Office for your Mac
Mac users have two ways to get Microsoft Office: a Microsoft 365 subscription billed every month or year, or a perpetual license that you buy once. Office 2021 Home and Business for Mac is the perpetual option in the 2021 generation. It installs Word, Excel, PowerPoint, Outlook and OneNote on one Mac, activates against your Microsoft account, and never asks for a renewal. For a freelancer with a MacBook, a home office iMac, or a small firm that prefers a predictable one-time cost per machine, it is the simplest route to genuine Office on macOS.
This edition is the sweet spot for most Mac buyers. Home and Student for Mac is no longer offered as a separate 2021 product in our store, and the full Office Professional Plus suite does not exist for macOS at all, since Access and Publisher are Windows-only applications. Home and Business gives you every Office for Mac application that Microsoft ships in the perpetual channel, with Outlook included for business email and calendars.
Key features of Office 2021 Home and Business for Mac
Word 2021 for Mac: modern editor, Line Focus reading, improved co-authoring when you save to OneDrive, and native support for Apple silicon.
Excel 2021 for Mac: XLOOKUP, XMATCH, dynamic array functions such as FILTER, SORT and UNIQUE, and the LET function for cleaner formulas.
PowerPoint 2021 for Mac: record slide shows with narration and ink, new stock images and icons, and improved slide show recording.
Outlook 2021 for Mac: full email, calendar, contacts and tasks with support for Exchange, Microsoft 365, Outlook.com, Gmail and IMAP accounts.
OneNote for Mac: notebooks that sync across your devices through your Microsoft account.
Refreshed design: the 2021 interface with rounded corners, a neutral palette and full Dark Mode support on macOS.
Apple silicon native: Office 2021 for Mac is a universal build that runs natively on M-series Macs and on Intel Macs.
Files created on the Mac open unchanged on Windows. Office 2021 for Mac reads and writes the same .docx, .xlsx and .pptx formats as Office 2021 for Windows, so a spreadsheet you build on your MacBook lands in a client's Excel on Windows with formulas, charts and formatting intact. Outlook 2021 connects to the same Exchange and Microsoft 365 mailboxes your colleagues use, and OneNote notebooks sync between your Mac, your phone and any Windows PC you sign in to with the same account.
Two things to know before you buy. First, the perpetual Office for Mac does not include Access or Publisher; those are Windows-only programs in every Office generation, so if you need a desktop database you will want a Windows PC with Office Professional Plus. Second, Microsoft 365 features that depend on the cloud, such as Designer suggestions in PowerPoint or Editor's premium grammar checks, are not part of the one-time-purchase edition. What you get is the complete set of core desktop applications, fully installed on your Mac and usable offline.

Compared with a Microsoft 365 Personal or Family subscription, Office 2021 Home and Business for Mac gives up the 1 TB OneDrive allowance and the continuous stream of new features, and in return costs nothing after the first payment. If you upgrade your Mac every few years and want the longest support window, the Office 2024 Home and Business for PC or Mac key is worth a look. If you only need a word processor, the Word 2024 for Mac single-app key is the smaller purchase.
System requirements for Office 2021 for Mac
Microsoft supports Office for Mac on the three most recent versions of macOS and drops the oldest one when Apple releases a new major version. Before you order, open the Apple menu, choose About This Mac and confirm that your macOS version is one Microsoft currently lists as supported.
Operating system: one of the three most recent macOS releases that Microsoft supports at the time of installation.
Processor: Apple silicon (M1 or later) or an Intel processor.
Memory: 4 GB RAM minimum; 8 GB recommended for large Excel workbooks.
Disk space: about 10 GB of available storage for the full suite.
Display: 1280 x 800 or higher.
Internet connection and a free Microsoft account for redemption, download and activation.
Older Macs that cannot run a currently supported macOS are the one case where this edition is not the right pick. For those machines, the Office 2019 Home and Business for Mac or Office 2016 Home and Business for Mac keys were built for earlier macOS releases; read the requirement notes on those pages carefully, because Microsoft no longer updates them. If your Mac can be upgraded to a current macOS, do that first and buy the 2021 edition: it is the version that still receives security patches, and it is the one we recommend for any Mac that serves as your main work machine.
How the Office 2021 for Mac license works
Office Home and Business for Mac is licensed per Mac and activated through a Microsoft account rather than a product key typed into the app. You redeem the 25-character key once at setup.office.com, which attaches the license to your account. From then on, signing in to Word or Excel on that Mac activates the suite. Keep the account details safe: they are your proof of ownership and the way to reinstall after a clean macOS install or a drive replacement.
The license is perpetual, meaning a one-time purchase with no subscription. Microsoft provides security updates for Office 2021 for Mac through October 13, 2026, and the applications continue to run after that date. Transfer rights are set by the license type: retail licenses can be moved to a different Mac after you sign out and remove Office from the old one, while OEM-style licenses stay with the original machine and volume licenses are meant for organizations. The license type for this listing is shown in the Product Overview table at the top of the page.

Frequently asked questions
Does Office 2021 Home and Business for Mac run on Apple silicon Macs?
Yes. Office 2021 for Mac is a universal build that runs natively on M1, M2, M3 and later Apple silicon chips as well as on Intel Macs. There is no Rosetta translation layer involved, so Word, Excel, PowerPoint, Outlook and OneNote launch and run at full speed. The requirement that matters is macOS version: your Mac must be on one of the three most recent releases that Microsoft currently supports at install time.
How is the Office 2021 Home and Business for Mac key activated?
You do not type the key into Word. Instead you redeem it once at setup.office.com while signed in with a Microsoft account, which links the license to that account. You then download the installer from Microsoft and sign in to activate. Keep the account credentials safe: they are how you reinstall after replacing a drive or resetting macOS. Our guide covers the whole process, and support is available 7 days a week.
What is the difference between this and Microsoft 365 on a Mac?
Microsoft 365 is a subscription with recurring payments, 1 TB of OneDrive storage and continuous feature updates. Office 2021 Home and Business for Mac is a one-time purchase: you pay once and keep the 2021 versions of Word, Excel, PowerPoint, Outlook and OneNote with security updates through October 13, 2026. If you dislike renewals and mainly need the desktop apps, the perpetual license is the more economical choice over several years.
Can I install it on a Windows PC as well as my Mac?
No. This key is for Office for Mac only and covers a single Mac. If you need Office on a Windows computer too, add a Windows license such as Office 2021 Professional Plus, or choose Office 2024 Home and Business, which can be redeemed on either one PC or one Mac. Mixing platforms on one key is possible only with Microsoft 365 subscriptions, which work differently from perpetual licenses.
Can I move the license to a new Mac later?
Transfer rights depend on the license type stated in the Product Overview table on this page. A retail license can be moved to another Mac: sign out of Office on the old machine, uninstall it, then install and sign in on the new Mac with the same Microsoft account. OEM-style licenses stay with the first Mac, and volume licenses are intended for organizations. Check the table before ordering if you plan to upgrade your Mac soon.
What if the key does not work or I change my mind?
Every order is covered by our 30-day money-back guarantee. If setup.office.com rejects the key or activation fails, contact us with a screenshot and a person will investigate, usually the same day, and issue a replacement key if the original is faulty. If we cannot make it work, you receive a full refund. Please note that a key which has already been redeemed to a Microsoft account cannot be returned, because it is now attached to that account.
