By default, Excel recalculates all the formulas in your worksheet automatically when you open your worksheet or change any entries, formulas, or names on which your formulas depend. If you worksheet is large, with many formulas, this can take several seconds or minutes.

While the formulas are being recalculated, the mouse pointer changes to an hourglass and you can’t make any changes to the worksheet.

You may want to temporarily turn off automatic calculation to save time until you are finished entering and changing the formulas in your worksheet. This is done easily, and we will show you how.

NOTE: If you don’t want to turn off the automatic calculation feature, and you have multiple processors in your computer, you can turn on the multi-threading feature, which could speed up the recalculation of your formulas by a little bit, depending on how many processors your computer has. We will show you how to turn on this option later in this article.
