Home & Business vs Microsoft 365?
Microsoft 365 costs $100+/year but adds cloud storage and always-current app versions. Home & Business is a one-time payment — same apps, no recurring fee. If the 2021 feature set covers your needs and you want to stop paying annually, Home & Business wins on long-term value.

Home & Business vs Home & Student?
Home & Business includes Outlook and grants commercial use rights — meaning you can use it for business work. Home & Student excludes Outlook and is for personal and educational use only.

Word for Mac
