Hi KimberlyJKG,
Welcome to Microsoft Community.
The reason for the subscription price increase is that the product team has added Copilot to all Office applications starting from January 16, 2025. As a cost for unlimited use of AI, Microsoft has raised the subscription price.

However, if you do not need this AI feature, you can downgrade your subscription to Microsoft 365 Classic subscription, which will reduce the subscription price by $30. Correspondingly, your monthly quota for using Copilot to assist in creating documents will be limited. For more information please refer to: Switching to Microsoft 365 Personal and Family Classic Plans - Microsoft Support
Although this is not my decision, I understand the urgency due to this sudden change. If you confirm that you need to switch to the Classic subscription, please click the following link and leave your phone number on the left side of the screen: https://go.microsoft.com/fwlink/?linkid=2168171. A support agent will call you back as scheduled, and you will need to provide the necessary information during the call so that the agent can assist you in switching to the Classic subscription in the backend.
I hope my explanation helps you understand the reason for your subscription price increase. If you have any other questions or want to share more context, please let me know in your reply!
Best Regards,
