Summary

In Microsoft Excel, all currently open documents use the same mode of calculation, regardless of the mode in which they were saved.

More Information

To help explain how the mode of calculation is determined, this article refers to the following hypothetical documents:

File name	Kind of document	Mode that is used to save the file
Auto1.xlsx	Workbook	Automatic
Manual1.xlsx	Workbook	Manual
Auto2.xlsx	Workbook	Automatic

The following statements apply to calculation modes in Excel:

• 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
• Automatic except for data tables
• Manual
• 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 if you have the checkbox 'Recalculate workbook before saving' checked under File > Options > Formulas.

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.

How to change the mode of calculation in Excel

To change the mode of calculation in Excel, follow these steps:

1. Click the Microsoft Office Button, and then click Excel Options.
2. On the Formulas tab, select the calculation mode that you want to use.

Iterative calculations can help find the solution to mathematical problems by running calculations over and over using previous results. This is made possible by computers that can run calculations repeatedly to find the likelihood of possible answers by getting closer to the results from different angles.

In Excel, you can reference a cell that contains a formula and use its result in an identical formula in a different cell. For this, you would need to copy the formula and references as many times as you want to repeat the process. This can work if your model is relatively simple, but doing so in more complicated workbooks might prove much more challenging, if not downright impossible to do.

An alternative and better approach is to use the Excel iterative calculation feature. You can create a formula that refers to the cell containing the formula. The formula can use the result of the previous calculations, thus automatically calculating the same thing over multiple iterations.

As easy as it sounds, there are a few things you need to consider. First of all, the number of iterations should be limited. Even though a higher iteration count usually means more accurate results, this also means longer calculations times – and sometimes crashes. Another thing to note is that when iterative calculations are disabled, Excel will show a warning as circular references are usually considered user errors unless you know what you’re doing.

To learn more about circular references please see: How to Handle Circular References in Excel

To activate and use circular references, you must first activate them by checking Enable iterative calculations option under the File menu.

Excel 2016 Mac Switch To Manual Calculations Download

Go to File > Options > Formulas > Calculation options section in Excel 2016, Excel 2013and Excel 2010.

In Excel 2007, go to Office button > Excel options > Formulas > Iteration area.

In Excel 2003 and earlier, go to Menu > Tools > Options > Calculation.

Enabling iterative calculations will bring up two additional inputs in the same menu:

• Maximum Iterations determines how many times Excel is to recalculate the workbook,
• Maximum Change determines the maximum difference between values of iterative formulas. Note that entering a smaller number here means more accurate results.

Iterative calculations stop when one of the conditions defined (iterations count or change value) are matched. For example, let’s assume that Maximum Iterations is set to 100 and Maximum Change to 0.001. This means that Excel will stop calculating either after 100 calculations, or when there’s less than 0.001 difference between the results.

Calculating Future Value of an Investment

Let’s assume that we have $10,000 and want to invest this money in a cash deposit (CD) account. We’re going to assume a monthly interest rate of 1.25%. You can download the sample workbook for this use case . To calculate the total value at the end of the 21st month, we’re going to calculate the principal for each month, and add the interest to the previous month.

Begin by entering the starting cash, interest, and the total value function like below.

=value * ( 1 + interest rate)

Then, select the cell with the initial cash value and add the reference of the total value function.

This will give a circular reference warning if iterative calculations are not enabled. If you haven’t done so already, enable this option and set the Maximum Iterations to 20 to find the interest for the 21st month. See the previous section Enabling Iterative Calculations to enable this feature.

Automatic Timestamp

Circular references can also be used to add time stamps into cells. You can download the sample workbook for this use case . Let’s assume we want to add time stamps to the orders entered in the table below.

We can use circular references to add a time stamp when a new order information is entered. To do this, begin by adding a new column into the table where you’d like to print the timestamps. Type in the formula,

=IF(A2<>””,IF(I2<>””,I2,NOW()),””)

This formula will check whether there’s data in Order Number (cell A2). If it’s not blank and the timestamp cell is empty, the formula will return the NOW() function.

Note that pressing the Enter key will give a circular reference warning if iterative calculations are not enabled. See the previous section Enabling Iterative Calculations to enable this feature. This time Maximum Iterations or Maximum Change numbers don’t mean much, because we only need a single iteration, so you can leave these two inputs in their default values.

Now, every time we enter a new order and create a new row, a timestamp will be automatically printed on the Timestamp column.
