Microsoft’s documented Personal-to-Family switch charges the full Family subscription price rather than only the price difference; the unused Personal term is converted into Family time at 92% and added to the new expiration date.[^1^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Switch between Microsoft 365 subscriptions")
What happened to the Personal subscription
When both subscriptions are purchased directly from Microsoft using the same Microsoft account:
- The new Family subscription starts immediately at its full purchase price.
- Remaining Personal days are converted at 92% and added to the Family subscription.
- Microsoft does not normally apply the unused Personal value as a $100 cash refund or charge only the $30 price difference.
Check Microsoft account → Services & subscriptions → Microsoft 365 Family and inspect the next billing or expiration date. It should be later than one year from the upgrade date if Personal time remained. The extension you received appears to be this documented conversion, rather than a refund adjustment.
If you want the Family purchase refunded
Refund eligibility is determined during cancellation; it cannot be confirmed from this forum.
- Sign in to Services & subscriptions using the Microsoft account that purchased Family.
- Find Microsoft 365 Family, then select Manage → Cancel.
- Review the cancellation page before confirming. It will state whether the purchase qualifies for a refund and provide the available next step.[^2^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Microsoft subscription refund policy | Microsoft Support")
In most cases, a directly purchased subscription may qualify within 30 days of its initial purchase or before its first recurring-billing date, whichever comes first. The most recent recurring charge may also qualify when cancellation occurs within 30 days, subject to the policy’s limits. Not every cancellation produces a refund, and prorated-refund rights outside those windows vary by country or region.[^2^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Microsoft subscription refund policy | Microsoft Support")
Before confirming cancellation: Family benefits can be removed from people sharing the plan, and storage allowances can be reduced. Review the cancellation screen’s effective date and refund offer carefully.
If cancellation offers no refund
Since the earlier request resulted only in converted subscription time, contact Microsoft Support and ask for a review of the Family purchase transaction, not a refund of the old Personal balance:
- Open Contact Microsoft Support from the refund-policy page.
- Enter the billing issue and select Get Help.
- If self-help does not resolve it, select Contact Support.
- Provide the Family order date, amount, order number, and the current Family expiration date. Do not post those details publicly.
If the subscription was bought from Apple, Google Play, Amazon, or another retailer, cancellation and refund requests must instead go to that seller; Microsoft cannot refund payments it did not receive.[^3^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Manage your Microsoft 365 subscription purchased through a third party | Microsoft Support")
