Difference Between Microsoft 365 Invoice Amount and Actual Credit Card Charge/Refund

Question

Hello,

I would like to ask for clarification regarding a difference between the billing amounts shown on my Microsoft 365 invoice and the actual amounts charged and refunded by my credit card company.

Here are the details:

• Product: Microsoft 365 – Teams Business Basic

Subscription period: 1 year

Payment date: March 3, 2026

Refund date: March 5, 2026

According to the Microsoft 365 invoice:

Charged amount: KRW 106,920

Refunded amount: KRW 106,627

However, according to my Korean credit card company, the actual transaction amounts were:

Actual charged amount: KRW 112,294

Actual refunded amount: KRW 110,407

As you can see, both the charge and refund amounts recorded by Microsoft differ from the amounts processed by the credit card company.

I would like to understand why there is a difference between the amounts shown on the Microsoft 365 invoice and the actual amounts charged and refunded by the credit card provider.

I would appreciate it if you could explain the exact reason for this discrepancy.

Thank you for your assistance.

Dear Moon Seoah,

Thank you for posting your question in the Microsoft Q&A forum.

I apologize for any inconvenience you may encounter when using our services/ products. Based on your description:

As a moderator, I do not have the tools to investigate your specific account directly, as this is a support forum between users. Moderators and collaborators, including external Microsoft employees, may not directly intervene in the functionality of Microsoft products or access internal systems. Our role is limited to providing technical guidance on reported problems, requests, or ideas.

To support this, Microsoft’s support team will need to step in. A technical support engineer can perform a remote session to investigate the situation, verify this issue with Billing Team. If the issue requires further attention, they can escalate it for deeper analysis.    

For the standard procedure outlined above, Office 365 global administrators may need to contact the Office 365 support team by submitting a service request.  

Here is what your Office 365 Global Admin should do next:             

1. Submit a Service Request: The Global Admin should create a service request with Microsoft support to get advanced technical assistance and diagnostics. For detailed instructions on how to get support, please refer to Get support - Microsoft 365 admin.        
2. Find Your Microsoft 365 Admin: If you are unsure who the Global Admin is within your organization, you can find guidance on locating them here: How do I find my Microsoft 365 admin? - Microsoft Support. 

Answer 2

The context only explains how Microsoft calculates and presents its own invoice amounts and how card billing/dunning work; it does not describe any mechanism where Microsoft’s invoice total in KRW differs from the KRW amount that appears on a Korean credit card statement. It also does not document bank/card-side effects such as:

• Foreign-exchange conversion or dynamic currency conversion
• Card network fees or issuer surcharges
• Temporary authorizations vs. final postings
• Bank-side rounding rules or refund handling

Because these bank/issuer behaviors are not covered in the provided documentation, the exact reason for the discrepancy between the invoice amounts (KRW 106,920 / 106,627) and the card statement amounts (KRW 112,294 / 110,407) cannot be determined from the context.
