not provided
Scenario

Solution 1Recommended

Set Excel Calculation Options to Automatic

The most common reason totals stop updating is that the workbook's calculation setting has been accidentally switched to Manual.

When Excel is set to Manual calculation, formulas will not update their results when you change the underlying data. You must switch this setting back to Automatic to restore normal functionality.

1
Navigate to Formulas

Open your Excel workbook and click on the 'Formulas' tab located on the top ribbon.

2
Open Calculation Options

Find the 'Calculation' group on the far right of the ribbon and click on 'Calculation Options'.

3
Select Automatic

Choose 'Automatic' from the drop-down menu. Your formulas should instantly calculate and display the correct totals.

Quick Recalculation: If you need to stay in Manual mode but want to update totals immediately, simply press the F9 key on your keyboard to force Excel to recalculate all open workbooks.
