Office 2024 vs Office 2021 vs Microsoft 365: Which One Should You Buy?
Share
If you're trying to choose between a one-time Office license and a subscription, you're not alone. The best option depends on how you work: offline vs cloud, solo vs team, and "set-and-forget" vs always-up-to-date.
Quick definitions (in plain English)
- Office 2021: A one-time purchase for classic desktop apps; you typically get security updates, but not a steady stream of new features.
- Office 2024: A newer "perpetual" (one-time) generation similar in spirit to Office 2021, aimed at people who want desktop apps without ongoing subscription fees.
- Microsoft 365: A subscription that includes desktop apps plus cloud services and continuous feature updates (varies by plan).
Side-by-side comparison
| What matters | Office 2021 | Office 2024 | Microsoft 365 |
|---|---|---|---|
| Payment model | One-time | One-time | Subscription |
| Feature updates | Limited after purchase | Limited after purchase | Ongoing updates/new features |
| Cloud collaboration | Basic | Basic | Strong (cloud-first, real-time co-authoring) |
| OneDrive included | Not bundled by default | Not bundled by default | Typically included (often 1 TB per user depending on plan) |
| Microsoft Teams | Not included | Not included | Included |
| Mobile apps | Limited functionality | Limited functionality | Full access with subscription |
| Devices per license | Tied to 1 PC (Retail/OEM) | Tied to 1 PC (Retail/OEM) | Multiple devices (5 for Personal, per-user for Family) |
5-year cost comparison
For a typical individual user, here's roughly what each option costs over five years:
- Office 2021 Pro Plus (via LicenGold): one-time cost, no ongoing fees. The cheapest option if you don't need cloud features.
- Office 2024: similar one-time model to 2021, slightly newer app generation, same long-term economics.
- Microsoft 365 Personal: roughly $70/year, so around $350 over 5 years — but that includes 1TB of cloud storage and continuous updates.
- Microsoft 365 Family (up to 6 users): roughly $100/year, close to $500 over 5 years, split across the household.
Verdict: if you don't need extra cloud storage, real-time collaboration, or Teams, a one-time Office 2021 or 2024 license is significantly cheaper over time. If you rely on cloud sync, multiple devices, or work with a team, Microsoft 365's subscription cost is usually justified by the extra functionality.

Frequently Asked Questions
Do I need internet to use Office?
For basic desktop editing, Office desktop apps work offline. Cloud features — syncing, co-authoring, cloud storage — need an internet connection.
Can I switch from a one-time license to Microsoft 365 later?
Yes. You can move to a Microsoft 365 subscription at any point by signing in with your Microsoft account and subscribing — your existing Office 2021 or 2024 installation isn't affected.
Is a one-time license a safe long-term choice?
Yes, especially if you keep the device itself secure (updates, strong passwords, antivirus) and don't rely heavily on cloud collaboration. Security patches for the Office apps themselves continue for a defined support window after release.
How many devices can each option cover?
Office 2021 and Office 2024 licenses are tied to a single PC (Retail licenses are transferable to a new PC; OEM licenses are not). Microsoft 365 covers multiple devices per subscription, depending on the plan.
