VERSION COMPARISON
Office 2021 vs Office 2024
Both are perpetual licences — pay once, use for life. So which one is right for you? Below you'll find every difference, Microsoft's support dates and our live store prices at a glance.
Short answer
Our general recommendation is Office 2024: Microsoft support runs 3 years longer (October 2029 vs October 2026) and the feature set is more current. Office 2021 still makes great sense when you find it at a clearly lower price — or if you need Publisher.

Which One Is for Whom?
Home & student use
For everyday Word, Excel and PowerPoint, both versions are more than enough — pick whichever fits your budget.
Businesses & long-term use
If you want security updates until 2029, Office 2024 is the right call. Buy once and forget about it for years.
Publisher users
Microsoft retired Publisher and left it out of Office 2024. If you need Publisher, Office 2021 is your only option.
Cloud & multi-device users
If OneDrive storage and multi-device sync matter most, look at the subscription instead of perpetual versions: Office 365 Pro Plus
Frequently Asked Questions
Can my Office 2021 key be upgraded to Office 2024?
No. Perpetual licences are version-specific; moving to Office 2024 requires a new licence. Your 2021 key keeps working — a new release never invalidates an old licence.
Will Office 2021 keep working after October 2026?
Yes — it keeps running and activating on the computer it's installed on. Microsoft just stops providing security updates and technical support. If staying current matters, choose Office 2024.
Why is Publisher missing from Office 2024?
Microsoft decided to retire Publisher, so it was not included in the Office 2024 suite. If you need Publisher, buy Office 2021.
How many computers can these licences be used on?
The Retail keys in our store are for 1 PC and provide a one-time activation. Reinstalling after a format requires a new licence.
How fast is the key delivered?
Usually within 1-90 minutes after payment — 100% genuine and invoiced, sent to your e-mail together with our step-by-step setup guides.
