The short answer

“Alternative to Office 365” has three realistic answers, but for most people it comes down to one. If you are used to Word, Excel and Outlook and do not need to be tied to the cloud, the perpetual Office licence is the most economical choice: pay once instead of every year. Google Workspace is worth it above all for genuine team collaboration in the cloud. LibreOffice is free, but it costs you an adjustment period and layout risk when exchanging files.

Work it out for yourself: the calculator shows what each option costs over the years. The detailed comparison follows below.

Cost calculator: Office vs. alternatives

Office perpetual license

Recommended

One-time purchase

CHF 119

over 3 years

Buy once, use indefinitely. Familiar interface, no subscription.

View Office licenses →

Microsoft 365

Subscription, per year

CHF 237

over 3 years

Ongoing subscription with cloud storage and updates, payable as long as used.

Google Workspace

Subscription, cloud

CHF 234

over 3 years

Cloud and team tool, also a subscription. Often unnecessary for single users.

LibreOffice

Free

CHF 0

over 3 years

Free, but a different program: re-learning, layout risk when exchanging files, no manufacturer support.

Rule of thumb: From around 2 years onward, the perpetual Office license is cheaper than the Microsoft 365 subscription. LibreOffice costs nothing, but means re-learning and a layout risk when exchanging files.

Which alternative suits which profile

  • Perpetual Office licence. If you are used to Word, Excel, PowerPoint and Outlook, do not need cloud sharing, and want to use it for longer than 2 years. Best total cost if 3+ years.
  • LibreOffice. If your budget is zero. Be prepared for it: a different program, a different way of working, with menus, terms and workflows that are not those of Office, so the adjustment takes time. With Word/Excel files from the Microsoft world the layout may shift, sometimes significantly with complex documents. There is no vendor support, only the community.
  • Google Workspace. If you need real-time team collaboration and want cloud storage to be central. For a pure single-user case it tends to be expensive.

Häufige Fragen

What is the best alternative to Microsoft 365?

It depends on the use case: an Office perpetual license for a standard single user, LibreOffice for a zero budget and an open-source preference, Google Workspace for cloud/team collaboration. For 3+ years of use and no cloud requirement: an Office perpetual license is almost always the most economical.

Is LibreOffice really compatible with Word?

LibreOffice reads and writes Word files. Simple documents usually open as expected. With complex Word documents containing embedded objects, special formatting or macros, the layout can shift, sometimes significantly. If you exchange files with others, you will notice it. On top of that comes getting used to a different interface and the lack of vendor support.

What does an Office perpetual license cost compared to Microsoft 365 Personal?

Office 365 Personal currently costs around CHF 79. per year. An Office 2024 perpetual license from us is a one-time CHF 89–249 (depending on the edition). After 2 years the perpetual license is more economical.
