In Microsoft Excel, all currently open documents use the same mode of calculation, regardless of the mode in which they were saved.
To help explain how the mode of calculation is determined,
this article refers to the following hypothetical documents:
Collapse this tableExpand this table
|File name||Kind of document||Mode that is used to save the file|
The following statements apply to calculation modes in
- The first document that is opened uses the calculation mode with which it was last saved. Documents that are opened later use the same mode. For example, if you open Auto1.xlsx and then open Manual1.xlsx, both documents use automatic calculation (the mode used by Auto1.xlsx). If you open Manual1.xlsx and then open Auto1.xlsx, both documents use manual calculation.
- Changing the calculation mode of one open document changes the mode for all open documents. For example, if Auto1.xlsx and Auto2.xlsx are both open, changing the calculation mode of Auto2.xlsx to manual also changes the mode of Auto1.xlsx to manual.
- All sheets that are contained in a workbook use the same mode of calculation. For example, if Auto2.xlsx contains three worksheets, changing the mode of calculation of the first worksheet to manual also changes the mode of calculation to manual in the other two sheets.
- If all other documents are closed and you create a new
document, the new document uses the same calculation mode as the previously
closed documents. However, if you use a template, the mode of calculation is
the mode that is specified in the template.
- If the mode of calculation in a workbook changed and the file is saved, the current mode of calculation is saved. For example, if Auto1.xlsx is opened, Manual1.xlsx is opened, and Manual1.xlsx is immediately saved, the mode of calculation is saved as automatic.
How to control the mode of calculation
All open documents use the same mode of calculation. You must follow special procedures to work with documents that use different calculation modes. For example, if you are working with Auto1.xlsx and you want to open Manual1.xlsx in manual calculation mode, take one of the following actions:
- Set Auto1.xlsx to manual calculation mode before you open Manual1.xlsx.
- Close Auto1.xlsx (and any other open documents) before you open Manual1.xlsx.
There are four modes of calculation that you can select in Excel. They are as follows:
- Automatic except for data tables
- Recalculate workbook before saving

|Mode||Time when calculation occurs|
|Automatic||When you make any change to the document. All affected parts of the document are recalculated.|
|Automatic except tables||When you make any change to the document. All affected parts of the document except tables are recalculated. A table is recalculated only when a change is made to it.|
|Manual||When you press F9, click Options on the Tools menu, click the Calculation tab, and then click Calc Sheet.|
|Manual / Recalculate before saving||When you press F9 or click Calc Sheet on the Calculation tab on the Tools/Options menu. Calculation also occurs every time that you save the file.|
Recalculate the active sheet
To recalculate only the active sheet, use one of the following methods:
- Press SHIFT+F9.
- Click Calculate Sheet on the Formulas menu in the Calculation group.
Recalculate all open documents
To recalculate all open documents, use one of the following methods:
- Press F9.
- Click Calculate Now on the Formulas menu in the Calculation group.
