# Office 2021 vs Office 2024

> Source: https://karincalisans.com/en/compare/office-2021-vs-office-2024/ · Updated: 2026-07-30 · Publisher: Karınca Lisans

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:

## 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.
