Manual recalculation is useful when you have a large spreadsheet that takes several minutes to recalculate. If you prefer keyboard shortcuts, you can recalculate by pressing the F9 key. When this option is set to manual, Excel recalculates only when you click the Calculate Now or Calculate Sheet button. This means that, if you have a formula that totals up your sales and you change one of the sales, Excel updates the total to show the correct sum. When this option is set to automatic, Excel recalculates the spreadsheet’s formulas whenever you change a cell value. On the dropdown list, verify that Automatic is selected. On the Formulas ribbon, look to the far right and click Calculation Options. You’ve created the reports for your management meeting, and, just before you print copies for the executives, you discover that the totals are all showing last month’s values.
