Fix Missing Prorated Credit After Upgrading Microsoft 365
Question details
The user is seeking an explanation and solution for not receiving a prorated credit after upgrading to a higher-tier Microsoft 365 subscription plan.

- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Upgrading from a lower-tier Microsoft 365 plan to a premium plan.
- Observed behavior
- The expected prorated refund or credit for the unused time on the original subscription has not been applied to the account or payment method.
Ensure you have access to the email account associated with your Microsoft 365 subscription and gather your recent order numbers and billing statements before proceeding.
Verify Billing Details and Contact Microsoft Support
Check your Microsoft account's order history to confirm the transaction status and reach out to Microsoft Support if the credit is genuinely missing.
Prorated credits depend heavily on how and where you purchased the original subscription. Subscriptions bought through third-party vendors (like Apple or Google) handle billing differently than direct Microsoft purchases. In many cases, the prorated amount is applied as an extension of time to your new subscription rather than a direct cash refund.
Go to the official Microsoft Account website and log in using the email address and credentials tied to your Microsoft 365 subscription.
Click on the 'Payment & billing' section from the top navigation menu, then select 'Order history' to view your recent upgrade transaction.
Look for your recent upgrade purchase and check for any pending credits, applied discounts, or notes regarding refunds being applied to the new subscription cost.
If no credit is visible and your subscription time was not extended, navigate to the Microsoft Support page, select 'Microsoft 365', and choose 'Billing and payment updates' to speak with a representative.
Give the support agent the details of your previous plan, your new premium plan, and the associated order numbers from your billing history so they can trace the missing credit.

Frequently Asked Questions
Why did I not receive a prorated refund when upgrading via the Apple App Store?
If you originally purchased your Microsoft 365 subscription through a third-party vendor like Apple or Google Play, Microsoft cannot process the prorated refund directly. You must manage the cancellation and request a refund through the respective app store's subscription management page.
How is the prorated credit calculated during an upgrade?
Microsoft calculates the credit based on the unused time remaining on your original subscription. This remaining value is usually applied to extend the duration of your new, upgraded subscription rather than being issued as a direct cash refund to your credit card.
Does the prorated credit apply if I switch to a completely different product family?
Typically, prorated credits only apply when upgrading within the same product family (e.g., from Microsoft 365 Personal to Microsoft 365 Family). Switching between different commercial licenses or completely distinct software products may not trigger an automatic prorated credit.
How long does it take for a prorated credit to show up in my account?
If the credit is being applied as a cash refund to your original payment method, it typically takes 3 to 5 business days for Microsoft to process. However, some banks and credit card issuers may take an additional few days to reflect the transaction on your statement.
