This can make finding each incorrect formula difficult, especially for larger data sets. However, this pop-up and warning symbol won’t always appear if you’ve inserted multiple circular reference formulas into your workbook. A pop-up will appear, along with a warning symbol alongside the cell itself. When you insert a formula that contains a circular reference in Excel, it will usually warn you. There are a couple of ways you can do this, from spotting the error symbol on certain cells to using Excel’s error checking system to locate them for you. To get around this problem, you’ll need to locate and remove unwanted circular references in Excel. This is usually because it breaks the formula, preventing it from outputting a result (although a circular reference is, in many cases, a barrier to a result in the first place). Most users will want to avoid circular references appearing in their Excel workbooks.

How to quickly find and remove unwanted circular references in Excel Where possible, it’s recommended to avoid this kind of scenario, or (at the very least) to limit the number of formulas where iterative calculations could cause data validity issues. This requires a bit of tweaking to Excel’s default settings, however.Įxcel will throw up occasional errors with this kind of setting enabled, such as a zero output after quickly switching between selected cells. Combined with certain logical functions, such as an IF function, you can turn otherwise volatile formulas into static ones that don’t update. This is done by enabling iterative calculations, which are calculations that are repeated until certain conditions are met. If you decide you want to create a static result using functions that would otherwise change regularly, such as a timestamp, you could disable circular referencing to do so. Few users will want to disable it, but there is one advantage to doing so. Loops like these aren’t ideal for users working in an Excel workbook, largely because the excess calculations result in excessive memory usage (although the example above, by definition, wouldn’t result in any useful output anyway).Įxcel won’t try to give you a result-the warning is sufficient to stop the error. Because the overall result relies on the output of the initial cell ( A2), this still results in an error. However, C2 contains a simple calculation, =A2-1. For instance, A2 contains =B2, while B2 contains =C2. This also happens if, for example, you reference data in a cell that relies on the result of your first cell. A blue arrow connecting the two cells offers a graphical representation of the problem. There isn’t an answer for Excel to output, so it displays an error. This is a circular reference, as the “formula” can’t be completed. Both contain references to the other cell, with A2 containing =B2, and B2 containing =A2. Let’s assume you have two cells: A2 and B2. Calculating the result of a formula, when the cell containing that formula is part of the calculation, results in an endless loop that Excel can’t complete. What are circular references in Excel and how do they work?įor most users, a circular reference in Excel is problematic. How to create a circular reference formula in ExcelĪre you struggling with circular references in Excel? Then keep reading! 1.How to enable iterative calculations in Excel.
How to quickly find and remove unwanted circular references in Excel.What are circular references in Excel and how do they work?.Whether you’re looking to use circular references or avoid them entirely, this guide will explain: If you want to insert an iterative calculation (one that repeats itself a limited number of times until certain conditions are met), you might want to use a circular reference formula, but you’ll need to tweak Excel’s settings to allow it. However, there is one way you can use circular references in Excel to your advantage. For instance, if you’re analyzing data with a SUMIF formula, and one of the cells in your data set is referencing the output from the same cell containing that formula, Excel can’t calculate the result, causing this error to appear.
You’ll see circular reference warnings for any formula you try to insert into Excel that loops back to itself. We’ll explain everything you need to know about circular references (and how to avoid or potentially use them) in this step-by-step guide. As the formula can break its own result, this creates a circular reference. If you see a circular reference warning in Excel, it usually points to a formula in a cell that, in some way, refers back to itself.
