From Family to premium

Hello !

That's normal : when you upgrade your Microsoft 365 subscription, you'll be charged the full annual price immediately.
However, the amount you already paid is not lost. Instead, Microsoft converts the remaining value of your current subscription into extra time on the new subscription.

So, you'll be fully charged today, but your next renewal date will be pushed further into the future to compensate for the unused time you already paid for.

You can see the conversion table here : https://support.microsoft.com/en-us/office/switch-between-microsoft-365-subscriptions-3fcc1efc-2722-427f-8efa-db94b9b0a36b#switch-to-a-microsoft-365-subscription-with-more-features

Please let me know if you have any other question !

Upgrading from Microsoft 365 Family to a higher plan (such as Microsoft 365 Premium) should automatically take into account what has already been paid by converting the remaining days on the current subscription into extra time on the new one, rather than charging as if starting from scratch.

To upgrade while including the amount already paid:

1. Buy the new subscription correctly
   • Purchase the Microsoft 365 subscription to upgrade to using the same Microsoft account that currently has the Family subscription.
   • Do this from the Microsoft account that shows the active Family plan so the system can convert remaining time.
2. How the time/credit is applied
   • When upgrading from Microsoft 365 Family to Microsoft 365 Premium, the remaining days on Family are automatically converted and added to the new Premium subscription.
   • For this specific upgrade path, the conversion rate is 100%, meaning the remaining time on Family should be fully carried over to Premium.
3. If the site still shows full price with no recognition of prior payment
   • Confirm that:
     • The correct Microsoft account is signed in (the one with the active Family subscription).
     • The new subscription is being bought under that same account, not as a separate new account.
   • If it still appears as a full, separate charge with no indication of time carryover, contact Microsoft billing/support so they can check the account and correct the upgrade/credit.
