Formulas like =A1+1 (in cell A1) also cause circular reference errors.Americas Premier Beef Company. For example, cell A3 might contain the formula =(A1+A2)/A3.

For example, a formula that uses the IF function may work until a user enters an argument (a piece of data the formula needs to run properly) that causes the formula to calculate itself. In some cases, a formula can run successfully before it tries to calculate itself. And now you're probably saying, 'Hang on, a last calculated value?' Yes. Click OK or close the message window.When you close the message, Excel displays either a zero or the last calculated value in the cell.

When you turn on iterative calculations without changing the values for maximum iterations or maximum change, Excel stops calculating after 100 iterations, or after all values in the circular reference change by less than 0.001 between iterations, whichever comes first. If you do, you can enable iterative calculations, but you need to determine how many times the formula should recalculate. This can slow your computer down, so iterative calculations are usually turned off in Excel.Unless you're familiar with iterative calculations, you probably won't want to keep any circular references intact. The following list shows some, but not all, the scenarios in which the warning message will appear:You create the first instance of a circular reference in any open workbookYou remove all circular references in all open workbooks, and then create a new circular referenceYou close all workbooks, create a new workbook, and then enter a formula that contains a circular referenceYou open a workbook that contains a circular referenceWhile no other workbooks are open, you open a workbook and then create a circular referenceAt times, you may want to use circular references because they cause your functions to iterateвЂ”repeat until a specific numeric condition is met.

The smaller the number, the more precise the result and the more time that Excel needs to calculate a worksheet.An iterative calculation can have three outcomes:The solution converges, which means a stable end result is reached. This is the smallest change in any calculated value. The higher the number of iterations, the more time that Excel needs to calculate a worksheet.In the Maximum Change box, type the smallest value required for iteration to continue. On the Mac, click Use iterative calculation.To set the maximum number of times that Excel will recalculate, type the number of iterations in the Maximum Iterations box. If you're using Excel for Mac, click the Excel menu, and then click Preferences > Calculation.If you're using Excel 2007, click the Microsoft Office Button , click Excel Options, and then click the Formulas category.In the Calculation options section, select the Enable iterative calculation check box.

For example, after the first iteration the result is 1, after the next iteration the result is 10, after the next iteration the result is 1, and so on.You can always ask an expert in the Excel Tech CommunityВ or get support in the Answers community.
