How to Switch to Manual Calculation in Excel 2013

The formulas that you create in your Microsoft Excel 2013 worksheets can be as complex or simple as you need them to be. But one common element of Excel formulas is their usage of values that are stored in various cells on the worksheet. By default Excel 2013 will automatically update if you change the value in a cell that is part of a formula. But there are situations where this behavior may not be ideal, such as when you are working with very large spreadsheets that need to perform many complex operations when you change the value in a cell. This can cause issues with Excel’s performance.

Fortunately this automatic calculation feature is not a mandatory setting in Excel 2013, and you can instead switch to a manual calculation option. This will require you to calculate your values on your own, but it can save you some time if constant formula calculations were negatively impacting your spreadsheet work. Our guide below will show you how to switch to the manual calculation option for a worksheet.
