Office 2024 or Microsoft 365: which one should you choose in 2026?
The question comes up every time you change computers: should you pay once for Office 2024, or subscribe to Microsoft 365? Both install Word, Excel, and PowerPoint on your computer, with the same interface and file formats. The difference is not in the software but in the contract. And depending on how you use it, the cost difference over five years can be considerable—or entirely justified.
Two opposing business models: one-time purchase versus subscription
Office 2024 is sold as a one-time purchase. You pay once, install the suite, and continue using it for as long as the software works on your system. There is no renewal, recurring charge, or expiration date for the license itself. Microsoft calls this model a perpetual license: the version you buy remains the version you own.
Microsoft 365 works the opposite way. You own nothing: you pay for usage rights, monthly or annually. As long as the subscription is active, the applications are fully featured and update automatically. When payment stops, the desktop applications are not uninstalled but switch to a reduced-functionality mode: you can open and view your documents, but you can no longer edit them normally. Your files remain yours, but the tool for editing them becomes paid again.
This is the starting point for any comparison. One is a purchase, the other is a rental. Neither is objectively better; they meet the needs of two different usage profiles.
What each includes
The most common confusion concerns what the two offers actually contain. On the desktop, the applications are largely the same. What changes is the exact list depending on the edition, and everything that comes with it.
| Item | Office 2024 (one-time purchase) | Microsoft 365 (subscription) |
|---|---|---|
| Word, Excel, PowerPoint | Yes, installed locally | Yes, installed locally |
| Outlook | Depending on the edition | Yes, depending on the plan |
| Access | Professional and Professional Plus editions, Windows only | Yes, depending on the plan, Windows only |
| Cloud storage included | No | 1 TB of OneDrive per user |
| Copilot in the applications | No | Yes, depending on the plan, with a monthly allocation of credits |
| New features | No, fixed version | Yes, continuously |
| Security updates | Yes, until the end of the lifecycle | Yes, as long as the subscription is active |
The Microsoft 365 column describes paid consumer plans with desktop applications. Entry-level web-only offers, retention plans, and business plans do not all contain the same elements: check the exact composition of the plan you are considering.
With a one-time purchase, the Family edition is limited to Word, Excel, PowerPoint, and OneNote. The Home and Business edition adds Outlook, but not Access: this latter application appears only in the Professional and Professional Plus editions, and only on Windows. If you are hesitating between the variants offered here, the Office 2024 Standard license covers everyday office work, while the Office 2024 Professional Plus license includes the most comprehensive set. The precise list of applications is shown on each product page: check it before ordering, as it is the only criterion that really matters.
One thing both offers have in common: Visio and Project are not ordinary office applications. They are never included, either in Office 2024 or in consumer subscriptions, and must be purchased separately, like the licenses for the Visio, Project and Access range.
Cloud features and storage
This is where Microsoft 365 justifies most of its price. The subscription includes 1 TB of OneDrive storage per user, with automatic folder backup, version history, and recovery after deletion. On a Family plan, each shared person gets their own 1 TB.
Next come real-time co-authoring, where several people work simultaneously in the same workbook, the full mobile and web applications, and Copilot. Since 2025, Copilot has been integrated into paid consumer plans, with a monthly allocation of artificial intelligence credits: each request in Word, Excel, or Outlook uses one credit, and higher-tier plans increase this limit. These benefits are tied to the subscription holder and cannot be freely shared with invited members of a Family plan.
Office 2024 provides none of that. It is a local installation, period. You can of course save your files to a free OneDrive account, Google Drive, a NAS, or a company server, and cloud saving works perfectly from the applications. But storage is not included, and simultaneous co-authoring remains limited compared with what the subscription allows. If you already have a storage solution, this omission costs you nothing. If you do not have one, it is a strong argument in favor of the subscription.
Feature updates
The distinction is clear and official: Office 2024 receives security updates, but not new features. The suite remains in the state in which it was released. No features added along the way, no surprises when restarting, and no buttons that move around. Many professional users see this as an advantage rather than a drawback: internal procedures, macros, and training remain valid over time.
Microsoft 365 is constantly evolving. You get new Excel features, Outlook updates, and AI capabilities over the months, without any intervention. The downside is symmetrical: the interface changes, and a feature may also disappear. The most telling recent example is Publisher, and two dates must be distinguished: Microsoft 365 subscribers will no longer have access to it after October 1, 2026, while the perpetual version will cease to be supported on October 13, 2026, when Office 2021 support ends. If you have .pub files, convert them without delay, regardless of which offering you use.
Finally, a perpetual license is not eternal. Office 2024 has a published support period running until October 9, 2029, for consumer editions. After that date, the software will continue to work but will no longer receive security updates. Since the official lifecycle may be adjusted, check Microsoft's published lifecycle page before making a ten-year plan.
Why target 2024 rather than the previous generation
The timeline also rules out a seemingly good idea: buying an older version today to save money. Office 2021, in both its consumer editions and its Mac versions, reaches end of support on October 13, 2026. After that date, the suite will still open, but will no longer receive any security updates. In our catalog, however, the Office 2021 Professional Plus license and the Office 2024 Professional Plus license are listed at the same price, €29.99 including VAT, and both are advertised for 3 devices. At the same cost, one goes out of support in a few weeks while the other remains covered for several years: the choice makes itself, unless you have a specific compatibility constraint.
The cost over time
The reasoning is not based on one year; it is based on the lifetime of your machine. A subscription renews: its cost is the sum of all renewals over the period you need it. A one-time purchase license has a cost that does not change, regardless of the number of years. Microsoft prices change regularly and have been revised several times since Copilot was integrated; check the current price on Microsoft's website rather than relying on a figure read in an article.
The calculation to make at home takes three lines. How much does the subscription you are considering cost for a full year? How many years do you plan to keep this computer? Multiply. Then compare this total with the price of a permanent license. At our store, the Office 2024 Professional Plus license is listed at €29.99 including tax, advertised for 3 computers, or less than €10 per computer, paid only once. This amount does not recur the following year.
Add the real value of 1 TB of OneDrive and Copilot for you to this calculation. If you use them every day, the subscription is defensible. If you never open them, you pay every year for services that remain unused.
Cases where a subscription remains preferable
There are situations where recommending a one-time purchase would be dishonest. A subscription is the right choice if you recognize yourself here:
- You work on the same files with others in real time, with people located elsewhere. Seamless co-authoring is a genuine daily benefit.
- You have no backup solution, and the 1 TB of OneDrive would meet that need. Paying for a backup and an office suite in the same subscription changes the equation.
- Copilot is part of your workflow. A one-time purchase does not provide access to it.
- You edit documents on your phone and tablet at least as much as on your computer.
- Several people live under the same roof, with many different devices to equip.
- You always want the very latest version, including after 2029, without having to pay again at that point.
Cases where a permanent purchase wins out
Conversely, a one-time purchase suits stable office use, which applies to most personal computers and small organizations:
- You open Word, Excel, and PowerPoint to write, calculate, and present. Nothing unusual, and that will not change.
- You no longer want recurring charges or renewals to keep track of.
- You already store your files elsewhere: Drive, NAS, company server, external drive.
- The computer often operates offline or on a restricted network.
- You are equipping a secondary computer, a family computer, or a machine dedicated to a specific task.
- You want an interface that stays unchanged because other people use it and you do not want to retrain them.
In these cases, a license from the Office 2024 range meets the need without anything superfluous, and this is the generation to choose rather than an earlier version, for the timeline reasons detailed above.
How to choose
Four questions are enough to decide, in this order.
1. Do you need the included cloud storage? If the OneDrive TB fills a genuine need, the subscription immediately gains an advantage. If you already have sufficient storage, this point becomes irrelevant.
2. Will you use Copilot? Answer honestly, not on principle. This is the feature that currently creates the biggest gap between the two offers.
3. How many years will you keep this device? This question cannot be answered using a fixed threshold, but with a calculator: multiply the annual subscription price you're considering by the number of years you expect to use it, then compare the total with the price of a one-time license. The longer the period, the more the one-time purchase stands out; you decide when the switch occurs in your case.
4. Do you work on your files alone? If so, you won't miss real-time co-authoring.
If your answers lean toward a one-time purchase, two practical details remain. If the device must also be upgraded to Windows 11 (support for Windows 10 ended on October 14, 2025, with the consumer Extended Security Updates program extending coverage only through October 2026), the Office 2024 Professional Plus with Windows 11 Professional pack addresses both issues in a single order. And if you work on Mac, the same timeline logic applies: check the generation listed on each page in the Office for Mac range; the prices and number of covered devices also differ from the Windows range.
In all cases, the key is sent by email within a few minutes of placing your order, along with the download link, an installation guide, and a VAT invoice. Installation is then carried out from this link, on the devices listed on the product page.
One final piece of advice: don't choose based on the version number, but on how you work. A fixed suite that you know well will save you more time than an evolving suite whose new features you will never use.
