## Sara’s Copy Shop – Break even analysis and what-if modeling in Excel [Videos]

Published on Sep 13, 2016 in Analytics, Financial Modeling

Last week, I asked you to share an analysis problem that you couldn’t solve in Excel. We got quite a few very interesting problems in comments and email. In this post, let me explain how to solve Sara’s copy shop problem using Excel.

What is Sara’s copy shop problem?
Thanks to Caroline who posted this problem.

Sara wants to open a copy shop. Each copier costs \$5,000 per year to lease. The rent & other fixed costs per month are \$300. There is a \$0.02 variable cost per copy. Each copier can print up to 100,000 copies per year. She plans to charge \$0.11 per copy from her customers. Sara estimates that the demand can be any of the 4 values – 500, 1000, 1500 or 2000 copies per day.

1. Build a model to estimate profit per given number of copiers & demand values
2. Find the mix of copiers & demand values that can make maximum profit for Sara (copiers – 1 to 6, demand – 500 to 2000)

## Doing Cost Benefit Analysis in Excel – a case study

Published on Jan 28, 2015 in Analytics, Charts and Graphs, Financial Modeling

Imagine you are the in-charge of finance department at Hogwarts. So one fine day, while you are practicing the spells, Dumbledore walks in to your office and says, “Our electricity bills are way too high. As the muggles don’t accept wizard money, we have to find a way to reduce our power consumption.”

So you summoned the previous 12 month utility bills to examine energy consumption patterns, and pretty soon you realized that most of the electricity consumption is due to the light bulbs. You suddenly have a brilliant idea. Why not replace the light bulbs with a variety that consumes low power? A light bulb moment indeed.

Your next step is to figure out what varieties of light bulbs are out there. Fortunately this is easier than catching a snitch in a game of quidditch. A quick search revealed that there are 3 types of light bulbs:

• Regular incandescent bulbs (the kind Hogwarts currently uses)
• Compact Fluorescent Light bulbs (CFL)
• Light Emitting Diode bulbs (LED)

Now your job is to do a cost benefit analysis of these options and pick one.

2. VBA automated implementation; and
3. Commercial add-in implementation.

This article provides a comprehensive overview of each of these methods and a summary of their advantages and disadvantages.

This article is written by Michael Hutchens from Best Practice Modelling.

This article provides a high level overview of Modular Spreadsheet Development principles. In next part the implementation of these concepts will be discussed.

### Modular Spreadsheet Development – An awesome concept

I want to share a concept with you so awesome that once you understand it you may never use Excel the same way again.

This concept, called Modular Spreadsheet Development, makes it possible to build spreadsheets exponentially faster while reducing the risk of errors and making spreadsheets much easier to understand.

This concept is not completely new, but I’m writing this article because the spreadsheet modelling world would be a much better place if it was more commonly adopted.

## Calculate CAGR (Compounded Annual Growth Rate) using Excel [Formulas]

Published on Apr 29, 2014 in Financial Modeling

Lets talk about how we can use Excel to calculate Compounded Annual Growth Rate (CAGR for short).

What is CAGR? What does it signify?

Let us say you are the CEO of ACME Inc. You have been selling various widgets since 2009. In your latest annual report you want to tell your shareholder at what rate you have been growing ACME Inc. sales. The figure are,

• 2009 – \$150 Mn
• 2010 – \$125 Mn
• 2011 – \$160 Mn
• 2012 – \$174 Mn
• 2013 – \$195 Mn
• 2014 – \$210 Mn

Now, if you see the growth rates, they are all over the place. Right from -16.67% to 28%. But you want to report a single annual growth rate.

This is where CAGR (Compounded Annual Growth Rate) comes handy.

## Creating Cash Flow Statement by Indirect Method – I

Published on Apr 11, 2012 in Financial Modeling

If there was a challenge in any Finance 101 course at any B School, I think Creating the Cash Flow Statement would score the max. When I was pursuing my MBA, the biggest enigma for me was to go from the Balance Sheet and Income Statement to the Cash Flow statement via the indirect route. I could never get it right!

There were two challenges, the bigger was obviously unclear concepts plus I didn’t know how to play with Excel! I have worked hard on both and let me show you, how they can be used to get the right cash flow statement in no time!

Actually the concept is simple and excel makes it run on steroids!
