Auto-sum not working until edit formula or save spreadsheet in Excel 2016

Are you having a problem that when updating an Excel spreadsheet, the formulas do not update automatically as values are entered or updates and the formula only updates after the formula is edited or the spreadsheet is closed and opened again.

This happens when Excel has been configured to NOT update formulas automatically. This setting applies to the program for the logged in user – so all spreadsheets will have the same issue.

The make Excel automatically calculate formulas again:

1. With Excel open, click on the File menu and then Options

2. In the left hand menu, select Formulas

3. Under Calculation options select Automatic

4. Click OK to save the changes

All the formulas will now automatically update using the current values.
