- Product
- Excel for the Web
- Device & OS
- not provided
- Scenario
- Checking the total of selected decimal values quickly using the status bar interface in the web browser.
- Observed behavior
- The status bar displays an inaccurate sum due to a browser-specific web calculation or rendering defect, even though the worksheet formula calculates the correct result.
Ensure you have saved your current workbook and take note of the specific web browser and version you are currently using.
Update or Switch Your Web Browser
Resolve browser-specific rendering defects by updating your current browser or switching to a supported alternative.
Because Excel for the Web relies on your browser's JavaScript engine, calculation anomalies in the status bar are often tied to specific browser versions.
Open your browser settings (e.g., in Firefox, click the menu button, click Help, and select About Firefox) to see your current version.
Allow the browser to automatically check for updates and install the newest version (e.g., updating to Firefox 130.1 or later).
If the status bar still shows the incorrect sum, open Excel for the Web using an alternative Chromium-based browser like Chrome, Edge, or Brave.

Verify Using the Worksheet SUM Formula
Bypass the web interface's status bar completely by relying on standard cell formulas, which calculate correctly on the server.
Open the Workbook in Desktop Excel
Use the desktop version of Excel as a temporary workaround to avoid web browser rendering anomalies entirely.

Frequently Asked Questions
Why does the Excel for the Web status bar show a different sum than the formula?
This discrepancy is typically caused by a browser-specific JavaScript calculation or rendering defect. When selecting and reordering decimal values, the web browser may temporarily miscalculate the intermediate value shown in the status bar, while the actual =SUM() formula computes correctly on the backend server.
Is this incorrect sum issue present in all web browsers?
No, this behavior is usually isolated to specific browser versions. For instance, it has been reproduced in older builds like Firefox 130.0.1, but users report that the status bar calculates correctly in Brave, Chrome 129, and newer versions of Firefox.
Does this issue affect the desktop version of Excel?
No, this is strictly a web-based anomaly. If you download the workbook and open it in a desktop version of Excel, the status bar will accurately reflect the sum of your selected decimal values without issue.
