First a story: Charlie and Chocolate Factory
Would you invest in my chocolate factory? It is just a $1,000 investment (And I would give you all the chocolate that you want for free!!)! I am going to produce 10,000 chocolates per year, which costs me $ 1,000 and I would be able to sell them for $ 1,010 in the market. Would you invest your money in my project?
You can just do a back of the envelop calculation to figure out that it would take me a hundred years to return back your money (Even if you were to charge no interest).
Believe me – Most of the decisions in finance are as simple as that! 😉 Its just that the numbers are obscure and figuring out the right numbers from the client takes a lot of time!
The first step for any meaningful evaluation is assimilating the facts CORRECTLY. In the world of finance (especially investment banking, equity research, etc.), for most of the analysis work you don’t need to be PHD material or a (ironically!!) researcher. Typically the work that is required to be done (as far as modeling in concerned) is quite routine. The skill that is highly in demand is consistency and an eye for detail.
As a banker your task starts by questioning each and every number that your client is giving you and recording it correctly. For comparisons, you start with ball park (industry) numbers and do some back of the envelop calculations to ascertain the feasibility of the project or the valuation numbers.
Figuring out relevant information
In finance there are two cardinal rules:
- Cash is the king
- Cash today is more important than cash tomorrow
Whatever affects the above two is going to have an impact on the valuation of the firm. So while evaluating any business proposal (or company), you should record all the facts that affect the cash and its timing.
For example, if we were to just pick an instance from the case (download here), which reads as:
I have done a thorough analysis and found out that the minimum initial investment needed in starting such kind of factory would be around USD 400 Mn (which includes the cost of machinery which has depreciation @ 20% every year and would also have a salvage value of 20mn after 10 years) and a starting working capital of $100mn which is 40% of revenue).
Then what is important from valuation perspective is the USD 400 Mn that goes out as investment (If it is all cash). Since it goes out on day 1, it is all the more important.
The depreciation is just an accounting concept (allocation of the huge cash that you invested to different accounting periods). It should have NO impact on the valuation of the project (as it does not affect the cash and also does not affect its timing). But when accountants create P&L, they deduct the depreciation from your EBITDA. So when you start the valuation, you should put that back in the cash available (and hence to record the information on depreciation).
Layout for Assumptions & Inputs
Creating a layout which can help you record the cash and its timing in a structured manner can help you eliminate the possibility of errors in your model. Typically you can categorize the recording of information in the following heads:
-
Initial investment that would be required to start the project (Investment decision)

-
How much of money is locked in the business apart from the plant and machinery (Working capital as investment)

-
How are you going to get your cash back (The operations)

-
How are you going to mix your equity and debt and what are the costs you pay for each

Once you have recorded the relevant information, you should draw out the timing of cash as well to figure out the valuation.
Templates to download
I have created a template for you, where the subheadings are given. You have to read the business case (here) and figure out which numbers go where. I also recommend that you try to create this structure on your own (so that you get a hang of what information is to be recorded).
Download the blank assumptions sheet

Also you can download this filled template and check, if the information you recorded, matches mine or not!
Download the completed assumptions sheet.
I am just doing that for the single sheet model and recommend that you do the same for multi-sheet model as a homework problem. If you face any issue, post your excel with the exact problem and we can discuss the way to move forward.

Next Steps
In the next installment, we would see, how we can calculate the cash that the project is going to earn in each financial period. It would mean using the recorded information and finding the items that contribute to cash change (and that don’t) and also the exact financial period, when that cash would flow in. For maximum benefit from the series, please try to fill it on your own and fill in the other parts of the model as well.

Hi Chandoo
As one of your students I have followed your detailed example through with great success. However, Excel is acting in an unexpected way and I wonder if you could take a look?
http://cid-95d070c79aef808e.office.live.com/self.aspx/.Public/Gantt%20Box%20Chart.xlsm
On my version, I have to type 40239 (Which equates to 2 Mar 2010) to get the chart to display 31 May 2010 (which should be 40329)!!??
Have I done something wrong or is Excel acting up?
Thx
Oli
PS Your example file in 2007 displays correctly.
Hi,
I like this idea a lot, but I agree the name is a little drab.
As an American I may just be seeing things, but to me the combination of lines and bars on your chart looks like a bunch of cricket bats.
Maybe you could work that into a catchier name. 🙂
Cheers!
Here is some code I use to keep the axis synched.
It may be useful to some of your readers
It is based on a comment I saw on Daily Dose of Excel.
Function SynchGanttAxis(Cname, lower, upper)
'Sets the X min and X max for Category axis
Application.Volatile
On Error Resume Next
'
'Top Horizontal Axis
With ActiveSheet.Shapes(Cname).Chart.Axes(xlCategory, 1)
.MinimumScale = lower
.MaximumScale = upper
End With
'Bottom Horizontal Axis
With ActiveSheet.Shapes(Cname).Chart.Axes(xlValue, 2)
.MinimumScale = lower
.MaximumScale = upper
End With
End Function
Function SynchVerticalAxis(Cname, lower, upper)
Application.Volatile
On Error Resume Next
' Excel 2007 only
'Right hand vertical axis
With ActiveSheet.Shapes(Cname).Chart.Axes(xlValue, 1)
.MinimumScale = 0
.MaximumScale = upper
End With
End Function
@Oli.. Can you check your file again.. I see 40329...
@Dave: Even I saw things.. the bars actually looked like lollipops. How about calling this lollipop chart - now that would be yummy and goes along the tradition of naming charts after eatables (bar, pie, donut...)
@Bob: Superb stuff... thanks for sharing 🙂
Hi Chandoo
This looks really good and I think it can also be applied to show project phases / milestones.
Question: Thinking further could this be amended to display a project lifecycle (Idea through to Implementation say 7 phases) on one bar / row? Just imagine 20 projects within a programme all on one chart one bar each showing their respective lifecycle stages i.e. on one page.
Idea: As the Gantt Box Chart this is quite intensive to set up re formatting etc how about the added extra of once you have completed this to "Save as template" i.e. saves the formatting and layout of the chart as a template so you can apply to future charts. Simple to do and will save the time formatting etc again and again and again.
Therefore tip: Click on your chart demo and then click on Save As template icon (2007) - edit file name and click on save. Ready to use / apply via Templates in Change Chart Type window.
Thanks and be very interested if the lifecycle question can be resolved
Mike
How embarrassing.
I was obviously suffering from numerical dyslexia. I was one of those days.
@Mike H: You can easily make this chart to work like a generic project lifecycle plan chart. All you have to do is,
1. in a separate sheet define the steps of lifecycle and various dates in a table (with 5 columns for each of the projects you have).
2. now use a control cell to input the project name you want to show in the chart
3. based on the input, use OFFSET Formulas to get the correct data
4. Rest is same as the tutorial above

Your solution is really smart but in the en Excel isn't meant to do stuff like this. I, as a former PM, always thought is was frustrating that you had to do stuff like this for something simple like a Gantt chart. So I built Tom's Planner. And would like to plug it here. I think it really solves the problem you are trying to solve in the most efficient way. Check out http://www.tomsplanner.com for a free account or play around with the demo.
Hi there,
Chandoo - this is really a very nice and helpfull chart - I adopted it, so I can report a forecast or the delay of a certain task (coming from my role as an auditor for projects).
One topic I´m currently struggeling with: I do have a project lasting for lets say 12 month. For a management reporting, I want to have kind of snapshot, lets say one month back and 2 month in the future. I tried with the offset formula, but failed. Any idea?
Thx

Hi Chandoo - fantastic xls. One thing I can't figure out how to do is adjust the alignment of the vertical axis. I would like to left align so that I could indent to represent sub tasks. Can that be done? Or is there a better way?
I've been trying to work out if there's a way to show weekends on the graph. The closest thing I've got is to add them on a secondary axis, but then I haven't been able to keep both axis lined up together! Any ideas?
Following on from this - is it possible to show things like holidays?
