Office 2021 is offered as a one-time purchase, so you just need to pay a single fee up advance to obtain Office programmes for a single computer.
Both PCs and Macs support one-time purchases.
However, as there are no upgrade options, you will have to pay full price if you want to move up to the following major release.
A subscription to Microsoft 365 gives users access to the most modern, collaborative capabilities in a streamlined, integrated manner.
The powerful Office desktop applications like Word, PowerPoint, and Excel are included with Microsoft 365.
Additionally, you get more online storage and cloud-connected features that enable real-time file collaboration.
You will always have access to the most recent features, fixes, and security upgrades, as well as ongoing tech support at no additional cost, with a subscription.
The Microsoft 365 Family plan allows you to share your subscription with your family for up to 6 people and use your apps on multiple PCs, Macs, tablets, and phones. You can choose to pay for your subscription monthly or annually.
