Question

Hi,

I am trying to understand why there was a 45.5% increase in my annual billing from last year to this year, how?

thanks

Answer 1

Microsoft announced last year they were increasing the price of a Microsoft 365 subscription by approximately 30% because they were adding new functionality like Copilot Ai to Microsoft 365.

If you do not need that new functionality, log into your Microsoft account online and choose to cancel the subscription, then on the next window, scroll down and you should see the hidden option to get Microsoft 365 Classic at the original cheaper price.

Answer 2

The most common reasons for a large year‑over‑year increase in Microsoft 365 annual billing are:

1. Price or plan change at renewal
   Subscription renewals can occur at a different price than the original term. For example, Microsoft 365 plans may increase in price when features are added (such as Copilot or other enhancements) or when promotional/introductory pricing ends. At renewal, the new license price is applied for the entire new term, which can cause a noticeable percentage increase.
2. Change in number of licenses/seats
   The total billed amount is calculated as:
   Total = license unit price × number of licenses + taxes/fees.
   If more users/devices were added during the year, or if an additional subscription (for example, another Microsoft 365 product) was purchased, the annual total will increase accordingly. Mid‑term changes are reflected on the next invoice and may show as credits and rebills.
3. Billing model change (timing of charges)
   Microsoft has updated billing so that many Microsoft 365 for business products are now billed upfront for purchases, renewals, recurring charges, and changes. In the month when this change takes effect at renewal, it is possible to see:
   • A final invoice for the previous term (billing in arrears), and
   • A new invoice for the upcoming term (billing upfront).
   While this usually appears as two invoices in one month rather than a simple percentage increase, it can make the current year’s total appear higher when comparing statements.
4. Taxes, fees, or currency changes
   Changes in tax rates, newly applied taxes/fees, or exchange rate differences (for non‑USD billing) can increase the final amount even if the base subscription price and license count remain the same.

To pinpoint the exact cause for this 45.5% increase:

1. Open the Microsoft 365 admin center (for business) or the Microsoft account dashboard (for home) and view the invoices for last year vs. this year.
2. Compare on page one of each invoice:
   • Product names and quantities (license count).
   • Unit prices per product.
   • Tax amounts and rates.
3. On page two (or invoice details online), check:
   • Whether any new subscriptions or add‑ons were added.
   • Any credits/rebills or mid‑term changes.
4. If there are unexpected or unrecognized charges, use the billing support options:
   • For Azure or business accounts, follow the guidance under How do I contact Azure billing support? and related billing support in the Azure portal or Microsoft 365 admin center.
   • For consumer Microsoft accounts, go to the Manage your payments page from the Microsoft account dashboard and use the Investigate option for specific charges.

If, after comparing invoices, the increase still cannot be explained by price, license count, or taxes, contact Microsoft Billing Support so they can securely review the account and invoice history.
