Office 365 Home is notable because it allows up to five installations of Office 2016 on PCs or Macs in the same household. On the consumer side, customers can choose between Office 365 Personal ($70 annually, $7 monthly) and Office 365 Home ($100 per year, $10 each month), while businesses have options that range from $99 to $240 per user per year. That's in contrast to Office 365, which requires a monthly or annual fee to continue using the software. The single-license, stand-alone editions are sold primarily at retail, and are dubbed 'perpetual' licenses because they require a one-time payment, but can then be used as long as the user wants. Office Professional 2016, available only for Windows, retained its $400 price tag.
