Here is a little experiment to freak out excel.
Go to cell C3 and write =C3 and press Enter. Excel would throw up nasty message saying, “Microsoft did not know what to do. We have a sent a support engineer to your home, but he is stuck at the round-about near your house.”
Well, not really. But what you did when you wrote the formula =C3 in cell C3 was, you created a circular reference.
What is a Circular Reference & why use them?
A circular reference is created when you refer to same cell either directly or indirectly.
We use circular references when we need circular references.
Excel Circular Reference Example:
For eg. (borrowed from John Walkenbach’s Excel 2010 Bible), lets say you run a fictitious company named Sky is the Ltd.
And you have a strange policy of donation 10% of your profits after tax to charity.
But, in your country, charity donations are tax exempt (they are expenses).
So charity = 10% * after tax profits
after tax profits = (revenues - expenses - charity)*(1-tax rate)
By definition, charity refers to after tax profits, which refers to charity, thus creating a circular reference.
Now, how would you find out how much to donate to charity?
Simple, we write formulas with circular references, like this:
But wait, just when you press enter after writing the formulas, Excel would scream bloody and curse your entire family for having a circular reference in your worksheet.
Enabling Iterative Calculation Mode
You must enable what they call iterative calculation mode before the formulas work. For this we must go to Excel Options.
In latest versions of Excel,
- Click on Office button
- Go to Excel Options, this is analogous to opening the bonnet of your car, but just a bit more confusing.
- Locate the “Formulas” on the left, click on it
- Now, check the “Enable iterative calculation”. This way you are telling Excel to evaluate references iteratively, up to 100 times (default).
- Click ok, close the bonnet. That is all.
In per-historic versions of Excel,
- Go to Menu > Tools > Options > Calculation Tab
- Check Iterative Calculation box. (see image)
Once you do this, your formulas will work nicely and you will find that the required charity donation to be made.
How to avoid Circular References?
As you can understand circular references are a pain in cell. You may want to get rid of them altogether. Thankfully, with careful inspection and a mug of coffee, you can reduce most circular references to simple formulas. For eg, in the above case, we can calculate charity amount directly by using the following equations.
But, keep in mind that, in few cases, circular references may be required. For eg. if you want to add timestamps to your workbook.
How to locate Circular References?
Do you know that you can find all the circular references in a workbook?
Whenever you see circular reference warning message, just go to formula ribbon and click on error checking options. You can see all the circular references there.
Note: In Excel 2003, you can see the same from circular reference toolbar (Menu > View > Tool-bars > Circular Reference)
Examples & More Resources on Circular References:
- Add timestamps to your workbook
- Team Todo List template in Excel
- Circular References & Other Repetitive Calculation Features in Excel
- Solve Circular References instead of using them
Do you do circular references?
I try to avoid circular references whenever possible. But in some rare cases, I think a circular reference gives elegant, shorter solution than a non-circular variation of it.
What about you? Do you use circular references often? What are the reasons / uses of them according to you? Please share your experience, tips thru comments.

We have only just got excel 2007 so this is helping me navigate my way through the differences cheers.
For Macro's i always add a Command Button, rename it something obvious, change the colour of it and finally add the following to its View Code section.
Application.Run "MAcro1"
This way anyone opening the file knows what to do if i ever win the lottery and dont make it in 🙂
Hi,
Good article. But I have this problem.
1) Customized QAT with a macro. Macro name = MacroX
2) Runs OK from original location (e.g. C:\TestLoaction1\TestFile.xls)
3) Copy past file to new location (e.g. C:\TestLoaction2\TestFile.xls)
Menu button now fails:
Cannot run the macro "C:\TestLoaction1\TestFile.xls'!MacroX' The macro may not be available in this workbook...
Of course the code is there, and macros are enabled.
Could get it to work after deleting and recreating macro custom buttons. So have to re-assign macro to QAT button every time I move the file?
If I put a form button on he worksheet and assign the macro to that, it's location independent.
Any ideas?
Thanks
@Ron
What you have said is correct
Macros within a worksheet are stored within the worksheet and hence follow it.
Macros referenced by a button in the QAT or elsewhere are locaed in a file and if that file is moved the linkages don't follow.
The easiest way around this is to store all your macros in a location that doesn't move and is in fact reloaded everytime that Excel starts and that is called the Personal.xlsx/b file.
These are refered to several time at Chandoo.org or have a read of
http://www.rondebruin.nl/personal.htm
or
http://office.microsoft.com/en-us/excel-help/deploy-your-excel-macros-from-a-central-file-HA001087296.aspx
In Excel 2003 and prior versions, a button added to the Toolbar maintained a DYNAMIC link to the file (e.g. Personal.xlsb) holding the assigned macro, such that if the file was relocated for any reason (by using Excel's native Save As command rather than just moving it via Windows Explorer), the link between the button and the file was updated.
I expected the same to occur with Excel 2007+, but alas, Microsoft in their infinite wisdom have removed another feature useful to advanced users (just as they did by removing the ability to design your own buttons)!!
So having just done some reorganisation of my files, I now have to remove and recreate every friggin macro button on my QAT (I have lots) - what a pain in the proverbial!!
Hi Hui,
Thanks for the help, that's really useful.
1) The macros I'm adding are for one specific Excel application, so I really wanted the macros to follow the file
2) I didn't want to have to pass other files around too and have users installing those - either Personal.xlsx/b or as an Add-In.
3) I realise now that the QAT additions will appear for other Excel workbooks in which I don't want the macros available.
So, it looks like I need to keep it local, by using a button on the worksheet. Unless you can suggest any way of adding to menus just for a specific workbook.
Thanks again for your help. Great site, so I'll be signing up for the emails.

I know I'm a little late jumping on this post, but wondering if anyone knows how to add a UDF to the QAT? I've saved my UDF in my personal workbook, but it does not show up in my list when I choose Macros when customizing my QAT. Suggestions? Thanks!!
@Cheryl: UDFs cannot be accessed like Macros. You can use them from other macros or from worksheet cells as formulas...
@David: If you save your macros file and then install it as an add-in then it will be always available for you.
The instructions work great when you are creating a new file, and it is still open. I find that I can't access macros after I've saved a file as an xlam and closed it. When I reopen the xlam, either by browsing to it, or by having it set to open as an addin using Excel Options, the macros are no longer available in the macros list when I go to edit the QAT. Any way around that?
[...] Add this macro as a button to Quick Access Toolbar [...]
I need to create a button that will run a macro. Once you click the button it needs to open up a browser asking you to select a report/file. Once you select the file, it will run the macro on the selected file and then save it as a new report with a name and the current date. I created the macro to sort/modify the report but I do not know how to do what I mentioned above. I hope this makes sense.
I'm having trouble adding a macro to the QAT. I've done everything up to step 5 but my macro isn't showing up. What am I doing wrong?

Hi,
Thank you for the explanation. Very useful for a recent switcher from office 2003 to office 2010.
My follow-up question is: in Excel (or ppt) 2010, can you customize the macro button that you put in the QAT?
In office 2003, once you chose the custom button for your Macro, you could then edit pixel by pixel the said button.
For instance, I've created 2 Macros in PPT that are converting all my slides to either English or French language, so I'd like one button to show EN and the other FR... that would be more meaningful that any of the possible "custom" office 2010 buttons
I read all the post and one important aspect to the QAT was never mentioned. That is, you have a macro driven worksheet that you want to share with other. You have customized the QAT with two icons to run the macros (VBA programs in reality). However, when the others receive the workbook, the icons are no where to be found. It's my understanding those "customized buttons" have been saved to an outside file, Excel.qat. QUESTION: Could one simply attach that file to your email, along with the worksheet, and tell the recipients to copy that file to correct location on their computer - C:\Users\\AppData\Local\Microsoft\Office|\
Would the customize macro buttons then appear in the worksheet and, more importantly, work? Thanks for your thoughtfulness and thanks for well written instructions Chandoo!
