Making charts is one of the most common use of Excel or other spreadsheet software. But do you know a simple trick that can save you lot of time while using excel charting features?
Chart Templates or User Defined Charts
yes, using chart templates can save you a lot of time.
If you use a particular type of chart or formatting all the time, you can save all the steps involved in making the chart by using templates.
Here is a simple tutorial on using chart templates in excel.
1. Prepare your chart

First step is to to prepare a chart that you would like to save to template. The chart can be a formatted version of one of the typical excel charts or a more complex combination chart.
2. Now save the chart as a chart template
In excel 2007 you can do this by selecting the chart and going to design tab in the ribbon and clicking on “Save as template”
For earlier versions of excel, right click on the chart and select chart type and go to “custom types” tab. Select “user-defined” as the chart type and click on the Add button to add the chart to excel chart templates.
3. Use the chart templates
Next time you need to insert a chart, use the templates and save time.

In Excel 2007 use the templates option. In earlier versions, use custom types to find your already save templates.
Bonus tip: Moving Chart Templates from One Computer to Another
If you want to move all your chart templates from one computer to another, just go to My Documents \Application Data\Microsoft\Excel and copy the file XLUSRGAL to the other computer. Make sure you are not overwriting the existing XLUSRGAL file, but just add the sheets from one file to another.
If you are using Excel 2007, the chart templates are stored as *.crtx files. Just locate them and copy to target system. Usually they can be found in \AppData\Roaming\Microsoft\Templates\Charts for Vista and My Documents \Application Data\Microsoft\Templates\Charts for XP.

Thanks again for a very helpful post.
I had a similar problem when trying to model a balance sheet and profit and loss projection. The problem was that interest expense (in P&L) was dependent on a cash shortfall (in BS) which had to be funded. The cash shortfall depended on how much interest was paid, so the mutual dependency made a circular reference.
I addressed it with a macro that calculated interest outside of the P&L, then pasted the calculated amount into the P&L as a value. The model was out of balance, but by repeating the pasting and calculating loop the imbalance reduced to zero. It was a bit messy, and had to be repeated every time a line changed - but it worked.
If I have to do it again I'll read this article again first and see if it can be done more elegantly.
Hi,
The use of a circular reference can be avoided in this case. Just make use of the geometric sum to calculate the interest required. I’ll walk through the example from the spreadsheet.
First calculate the cash needed each year without the interest expense. So you year 1 you need 55 Mn, year 2 105 Mn, and 190 Mn for year 3. The total amount to borrow for year 1 is then (50 Mn)/(1-interest_rate) = (50)/(1-0.1). For years 2 and subsequent the amount borrowed is the cash needed in that year plus the interest_rate times the amount already borrowed. For year 2 (105 + interest_rate * sum(previous debt raised))/(1-interest_rate)=(105+0.1*61.1)/(1-0.1).
This process avoids the need for a circular reference, and makes the calculation more stable.
Thanks,
Tristan
The question is for the year 1 in your case, the amount works out to 45 mn. However in the year 2 you have applied the loan amount as 61.1 mn.
Am I missing something ! Please help !
very helpful information!!!
using circular references and to make model more stable we can use combination of "IF" and "ISERROR" functions. i.e
=if(iserror(formula1),"",(formula1))
this formula will return blank value if there is any error otherwise give the result required.
I usually use this in my models and it makes them very stable......
🙂 🙂 🙂
@Terry: Thats right. Exactly same problem is seen in Interest - Cash cycle in P&L and Cash Flow statement as well. In our trainings on financial modeling in excel, we demonstrate using both the circular loops as well as the macros to take care of this problem. Circular loops have their own pitfalls. If the model enters into a state of error, the error percolates!
@Tristan: Thanks for pointing out. I agree with you that if circular loops can be avoided, they should be avoided.
@Yogesh: This is one way of avoiding the problem. Although circular loops have another problem that they make your sheet slower. Each time, there is a change in the sheet, all the calculations are redone. So if they can be avoided, they should be avoided.
Please note that this was an example (a large one indeed) and I didn't have space to speak about the pitfalls of this approach! I just wanted to illustrate an approach and am glad that some of you found it useful!
I think while posting, there is an error in the images! The last image should be flipped with the one that is posted in step VII!
I think you can try the following simple solution given by Microsoft itself to make the circular works:
Windows: Excel Options -> Formulas -> Put a tick on "Enable iterative calculation"
Mac: Excel -> Preference -> Calculation ->Put a tick on "Limit iteration"
You can change the maximum number of calculation iterations as well as the maximum changes which iteration stops for goal seeking or for resolving circular references based on the number you type in the maximum change box.
Thank you.
Hey All
I heard that we can take care of the circularity with the help of macro for IDC. Can anybody help on the steps to construct the macro for the same.

Vinay
Hi Vinay,
If you look closely, you are essentially copying the values from the interest calculation to the IDC in project cost.
Basically you can record a macro, that takes the values from interest and pastes special the values in IDC row in project cost.
Then you can run that recorded code in a for loop.
Hope this helps.
Thanks Param for reply.
But before calculating interest, i need to provide for Upfront Equity and Equity, which are essentially part of total project cost. Hence, i need to put in Upfront Equity and Equity to calculate the IDC which is again hitting the total project cost.
Bit of confused on how to remove this circular reference.
Regards
Vinay
Wow, this was a brilliantly simple post. I was looking online for a while before I found this page. Never seen this been explained so beautifully yet so crisply before. Thanks for saving my ass at work! (i'm relatively new to finance + modeling)
I'm not sure why but this web site is loading very slow for
me. Is anyone else having this issue or is it a problem on my end?
I'll check back later and see if the problem still exists.
[…] Project Finance Modeling using Excel – Part 1 & Part 2 […]
I have been reading your blog since my college days. Today, I'm writing just to say thanks.
We have calculated Financial Rate of return of a hydropower projects, and the observer has raised an observation regarding Total Project cost with IDC Rs. 8616.01 million (PKR) and with-out IDC 8352.46 million (PKR). How does the Financial nalysis be calculated on the basis of with-out IDC Or With IDC?????
Please helpf. if possible to spare some time.
