Are you working with a spreadsheet in Microsoft Excel 2010 where you change a cell that is included in a formula, but the result of the formula does not adjust to reflect your change? This occurs because the settings for formulas in the workbook have been set to manually calculate. This can be the preferred behavior if you are working with a very large spreadsheet with a lot of formulas, as there can be performance issues with Excel when too many formulas need to be calculated at the same time.
But for most smaller spreadsheets, and many Excel users, it is preferable that formulas update automatically whenever changes are made to relevant cell values. Fortunately this is a simple adjustment to make to your worksheet, and our guide below will show you how to do it.
Make Formulas Automatically Calculate in Excel 2010
The steps in this article will assume that your Excel spreadsheet is currently set to manual calculation. When a spreadsheet is set to manual calculation, the formulas will not update automatically when you make a change to a cell that is referenced with a formula. When the manual calculation mode is enabled, you will need to press F9 on your keyboard to force formulas to recalculate.
Note that there is another way to change the calculation settings in Excel 2010, and that option can be found on the Excel Options window. If you would prefer to use that method, you can skip to the next section.
Step 1: Open your file in Microsoft Excel 2010.
Step 2: Click the Formulas tab at the top of the window.
Step 3: Click the Calculation Options button at the right of of the navigational ribbon, then click the Automatic option.
After selecting the Automatic option, the formulas in your spreadsheet will automatically update based on any changes that you have made to cells that are included in formulas.
