Office 2021 for Mac License Keys

Office 2021 for Mac buying guide

All 4 Office 2021 for Mac listings above are genuine, perpetual licences delivered as a digital key by email. There are no monthly fees, no subscriptions and no rented “cloud account” that disappears if you stop paying. Pay once at the price you see, activate on your device, and the licence is yours for life. Below is a quick guide to picking the right edition, activating in minutes and getting help if you need it.

Which Office 2021 for Mac edition should I buy?

If you mainly write documents and crunch spreadsheets, the Home and Student edition (Word, Excel and PowerPoint) is the best value. If you also send a lot of email and run a small business, choose Home and Business — it adds Outlook. Power users who need Publisher and Access should go for Professional Plus. Every edition is a single one-time payment — no Microsoft 365 monthly fees, no renewals.

Why Office 2021 for Mac specifically?

Office 2021 remains the best value-for-money perpetual release — the same core Word / Excel / PowerPoint feature set you would get from a Microsoft 365 subscription, but for a single one-time payment. Runs on Windows 11, Windows 10 and the Mac editions cover macOS Big Sur and newer. Targets "Microsoft Office 2021 Professional Plus download", "Office 2021 Home & Student Mac" and "standalone Microsoft Word 2021 product key".

Mac or Windows?

Each Office 2021 for Mac listing is tagged with its operating system. Make sure you pick the Mac edition for macOS computers and the Windows / PC edition for laptops and desktops. If you accidentally buy the wrong one, we will exchange it free of charge within 30 days.
