This raises the price of a Microsoft 365 Personal subscription from $7 a month or $70 a year to $10 and $100; a family subscription goes from $10 a month or $100 a year to $13 a month or $130 a year. For current subscribers, these prices go into effect the next time your plan renews.

Microsoft has been testing adding AI-powered Office apps, the most important feature of Copilot Pro, into the Microsoft 365 subscriptions in recent months. What was previously only available in Australia, New Zealand, and a number of countries across Asia is now expanding to most markets worldwide.

The AI features that are now part of Microsoft 365 aren't unlimited. Subscribers will get a certain amount of AI credits each month, which are consumed when AI features are used. Microsoft is keeping Copilot Pro as an option for consumers with high usage needs, allowing Microsoft 365 subscribers to upgrade and pay the additional $20 per month.
