Should you buy Microsoft Office 2024 as a one-time purchase, or subscribe to Microsoft 365? This is one of the most common questions we get from customers, and the answer depends on how you use Office, how many devices you need it on, and whether you want cloud features like OneDrive storage and always-updated apps.
This guide breaks down every difference between Office 2024 and Microsoft 365, including pricing, features, device limits, and long-term cost so you can make the right choice.

| Apps included | Word, Excel, PowerPoint, Outlook (Pro Plus adds Access, Publisher) | Word, Excel, PowerPoint, Outlook, Access, Publisher, Teams |
| Updates | Security updates only (no new features) | Continuous feature updates + security patches |

What Is Microsoft Office 2024?
Microsoft Office 2024 is the latest perpetual (one-time purchase) version of Office. You pay once and own it forever. It includes the core Office apps: Word, Excel, PowerPoint, and Outlook. The Professional Plus edition also includes Access and Publisher.
Key characteristics:
- No subscription fees ever
- Receives security patches but no new feature updates
- Licensed for 1 device (or 3 devices with our multi-device key)
- Works offline without internet after activation
- Supported until approximately 2029
What Is Microsoft 365?
Microsoft 365 (formerly Office 365) is a subscription service. You pay monthly or annually and get access to the full suite of Office apps plus cloud services like OneDrive, Teams, and continuous updates. If you stop paying, you lose access to the apps.
Key characteristics:
- Always has the latest features and updates
- 1 TB OneDrive cloud storage included
- Install on up to 5 devices simultaneously
- Includes Microsoft Teams for video calls
- Access stops when subscription ends
OfficeAndWin also offers a Microsoft 365 Lifetime Account that gives you perpetual access without recurring payments.
Cost Comparison: Which Is Cheaper Long-Term?
This is where Office 2024 wins for most people. Here is the math:
| Scenario | Office 2024 Pro Plus | Microsoft 365 Personal |
|---|---|---|
| Year 1 | ~$25 (one-time at OAW) | $99 |
| Year 2 | $0 | $99 ($198 total) |
| Year 3 | $0 | $99 ($297 total) |
| Year 5 | $0 | $99 ($495 total) |
| 5-year total | ~$25 | $495 |
Even at retail prices, Office 2024 pays for itself within months. At OfficeAndWin prices, the savings are even more dramatic.
When 365 makes more financial sense:
- You need 1 TB OneDrive storage (worth ~$120/year standalone)
- You use Office on 5+ devices and would need to buy multiple keys
- Your organization requires Teams and SharePoint integration
- You need Copilot AI features for productivity
Feature Comparison: What Do You Actually Get?
Apps Available
| App | Office 2024 H&B | Office 2024 Pro Plus | Microsoft 365 |
|---|---|---|---|
| Word | Yes | Yes | Yes |
| Excel | Yes | Yes | Yes |
| PowerPoint | Yes | Yes | Yes |
| Outlook | Yes | Yes | Yes |
| Access | No | Yes | Yes |
| Publisher | No | Yes | Yes |
| Teams | No | No | Yes |
| OneDrive 1TB | No | No | Yes |
For most users, Word, Excel, PowerPoint, and Outlook cover 95% of daily productivity needs. Access and Publisher are niche tools used primarily in business environments.
Updates and New Features
Office 2024: Gets security updates for 5 years but no new features. The version you install today is the version you will have until you buy the next release.
Microsoft 365: Gets new features rolled out continuously. This includes new Excel functions, PowerPoint design tools, and AI-powered features like Copilot.
Practical reality: Most users never notice the difference. Core Office functionality (writing documents, building spreadsheets, making presentations) has been stable for years. The new features in 365 are nice-to-have, not need-to-have for most people.
Who Should Buy Office 2024?
- Budget-conscious buyers who want to pay once and be done
- Students who need Office for coursework (see our student guide)
- Small businesses that want predictable costs with no recurring fees (small business guide)
- Offline users who do not need cloud storage or collaboration
- Anyone on 1-2 devices who just needs core Office apps
Best options:
- 1 Windows PC: Office 2024 Professional Plus
- 1 Mac: Office 2024 Home and Business (Mac)
- Multiple PCs: Office 2024 Professional Plus (3-Device)
- Tight budget: Office 2021 Professional Plus (still supported until 2026)
Who Should Subscribe to Microsoft 365?
- Teams and collaboration-heavy workplaces that need shared calendars, Teams meetings, and SharePoint
- Users who need 1 TB cloud storage for documents, photos, and backups
- Multi-device users who switch between 3-5+ devices regularly
- Enterprise IT departments that need centralized license management
- Early adopters who want the latest AI and productivity features

Can You Switch Between Them?
Yes. You can switch freely:
- 365 to 2024: Cancel your subscription, buy a one-time key, install Office 2024. Your files (Word docs, Excel sheets) will open perfectly in either version.
- 2024 to 365: Subscribe to 365 and it will replace your Office 2024 installation. Your files transfer automatically.
- Use both: You cannot run both on the same device, but you can use Office 2024 on one PC and 365 on another.
Common Mistakes to Avoid
- Paying $99/year when you only use Word and Excel. If you do not use OneDrive, Teams, or Access, Office 2024 is almost always the better deal.
- Assuming 365 is required for Outlook. Office 2024 includes Outlook. You do not need a subscription to use email in Outlook.
- Buying the wrong edition for Mac. Office Professional Plus is Windows-only. Mac users need Home and Business (Mac). See our Mac buying guide.
- Not considering multi-device keys. If you need Office on 2-3 PCs, a 3-Device key is far cheaper than multiple single keys or a 365 subscription.
Frequently Asked Questions
Is Office 2024 a one-time purchase?
Yes. You pay once and own it permanently. There are no monthly or annual fees. It receives security updates for approximately 5 years.
Does Microsoft 365 include Office 2024?
Microsoft 365 includes the same apps (Word, Excel, PowerPoint, Outlook) but as continuously updated versions, not the 2024 perpetual release. The apps look and work almost identically.
Can I use Office 2024 without internet?
Yes. After initial activation, Office 2024 works completely offline. Microsoft 365 also works offline but requires periodic internet check-ins to verify your subscription.
Which is better for a small business?
For most small businesses (1-10 employees), Office 2024 with a one-time purchase is more cost-effective. For larger teams needing shared calendars, Teams, and centralized management, Microsoft 365 Business is worth considering. See our complete small business guide.
What happens when Office 2024 support ends?
Office 2024 will continue to work indefinitely after support ends. You just will not receive new security patches. Most users upgrade to the next version at that point, but many continue using older versions without issues.
The Bottom Line
For the vast majority of home users, students, and small businesses, Office 2024 as a one-time purchase is the smarter financial choice. You get the same core apps, pay a fraction of the cost, and own your software permanently.
Microsoft 365 makes sense when you genuinely need cloud storage, Teams, multi-device access across 5+ devices, or enterprise management features.
