Understanding Manual Calculation

by Allen Wyatt
(last updated September 12, 2015)

When you change a value in any cell of a worksheet, Excel automatically recalculates all the other formulas within the worksheet. This means that Excel is always up to date, based on any changes you may have performed.

If you have an absolutely huge worksheet or a terribly slow computer (or both), then doing a calculation after every change can get very tedious. In these situations, you can actually spend more time waiting on Excel to finish calculating than you do on entering information.

The answer to this problem is to configure Excel so that all calculations are done manually. This is easy to do by following these steps:

  1. Choose Options from the Tools menu. Excel displays the Options dialog box.
  2. Make sure the Calculation tab is selected. (See Figure 1.)
  3. Figure 1. The Calculation tab of the Options dialog box.

  4. Make sure the Manual radio button is selected.
  5. Click on OK.

Now, Excel does not calculate your worksheet automatically. Instead, you must press F9 whenever you want to update the results displayed within your worksheet.
