Microsoft Excel – Cells Not Updating Automatically

microsoft excelmicrosoft-excel-2003

I have a formula in a cell which counts the values in 2 other cells. Normally, after entering in the values in these 2 other cells, the formula cell updates automatically when Enter is pressed or when the cells are clicked out of.

However, for some reason, the value calculated by the formula does not update automatically. I am having to click on the formula bar, then I have to click enter for the formula cell to do its thing.

Why is this happening?

Best Answer

A likely cause is that Calculation is set to manual. To change this to automatic in the various versions of Excel:

  • 2003: Tools > Options > Calculation > Calculation > Automatic.

  • 2007: Office button > Excel options > Formulas > Workbook Calculation > Automatic.

  • 2010 and newer: File > Options > Formulas > Workbook Calculation > Automatic.

On Mac:

  • 2008: Excel Preferences > Calculation > Automatically

In some cases you may prefer to keep it set to manual, for example if there are many heavy calculations to perform. In such cases, you can simply press F9 when you want the calculations to update.
