Choose Office 2021 for the lowest price and the only suite that still includes Publisher — the software keeps working for life. Choose Office 2024 if you want the newest features and security updates through 2029.
Microsoft 365 charges you every month, forever — $70–$100 per year, over $400 in five years. Office 2021 Professional Plus costs $14.99 once. You give up the cloud extras and multi-device sync, but you keep the full desktop apps, working offline, permanently. If you work on one PC and want to own your software, the one-time purchase pays for itself in the first two months.
