Microsoft 365 vs. Office 2024 for Mac

Microsoft 365 vs. Office 2024 for Mac essentially means: monthly subscription versus a one-time purchase of a perpetual licence. Both include Word, Excel, PowerPoint and Outlook — the difference lies in the model, the cost and the feature scope.

The difference in one sentence

Microsoft 365 is a subscription with ongoing costs, cloud storage and constantly new features. Office 2024 for Mac is a one-time purchase: fixed programs, a fixed price, permanent use.

Cost comparison over five years

For pure Office use, the subscription adds up over the years. The one-time purchase stays at a fixed amount.

Who the one-time purchase is worth it for

Office 2024 for Mac is a good fit if you:

• mainly use Word, Excel and PowerPoint,
• don't want monthly costs,
• save your files locally,
• want a stable version over several years.

Who the subscription suits

Microsoft 365 makes sense if you:

• need a lot of cloud storage,
• always want the newest features,
• use Office on several devices at the same time,
• work closely with Teams and online collaboration.

An assessment for Mac users in 2026

Many Mac users are facing this decision right now, because Office 2019 for Mac switches to read-only mode on 13 July 2026 — documents can then only be opened and printed, no longer edited. Anyone who has to switch anyway is choosing between subscription and one-time purchase.

For most people who simply want to keep working, Office 2024 as a perpetual licence is the calmer choice: pay once, no subscription, no recurring decision. Anyone who needs the cloud and constant updates is better off with Microsoft 365.

Switching without data loss

Whichever model you choose: your existing Office 2019 files stay usable. You open Word, Excel and PowerPoint documents in their familiar format in both Microsoft 365 and Office 2024. With the one-time purchase, you install Office 2024 via download, open your files and keep working right away — the switch usually takes only a few minutes.
