Doing Cost Benefit Analysis in Excel – a case study

Doing Cost Benefit Analysis in Excel – a case study

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.

CP028: How to tell business logic & rules to Excel?

In the 28th session of Chandoo.org podcast, let’s figure out how to express business rules & logic to Excel.

What is in this session?

What good are spreadsheets if they can’t solve business problems?

But we all struggle when it comes to modeling real world business conditions in Excel. For example, if you have below business rule to decide how much discount to offer a customer,

  • If the customer bought 3 or more times previously and offer 15% discount
  • If the customer bought 1 or 2 times previously AND customer’s age is >40, offer 10% discount
  • If the customer visited our New York store between 6PM-9PM offer 5% discount
  • Else no discount

How would you go about modeling these in Excel?

That is our topic for this podcast session.

In this podcast, you will learn

  • The challenge of modeling business logic & rules in Excel
  • My struggles with such formulas in early days
  • 4 features of Excel that can help you with this.
  • Example business rules & how to write formulas

Unleash the pattern power with Excel Fill [quick tip]

When you are a “work from home” dad, you can see a lot of patterns. Here is one.

My kids come home from school by noon (they are too young for full day school). Right after lunch they watch their favorite cartoon program, Team Umizoomi, in which few fictional characters go about solving problems in the Umi city using maths. Milli, one of the characters is an expert with patterns. She solves problems by identifying patterns and unleashing pattern power. 

Team Umizoomi & Excel Fill – How do they link up?

Here is how they link up.

Imagine you have a workbook where you need to follow a pattern, like above.

You too can unleash the pattern power. What more… you needn’t break in to a song sequence every-time you unleash the power.

8 Reasons you must get better at Excel in 2015

8 Reasons you must get better at Excel in 2015

This is a guest post by Sohail Anwar

Why do so many of us use Excel? Let’s trace it back to the ’80s when Microsoft hit gold by being the first out of the blocks with the widely available operating system that was somewhat dummy proof.

Suddenly everyone could aspire to launch ‘Nukes’ like a fresh faced Matthew Broderick in the film ‘War Games’. 

By the early 90’s Windows had become even more established relative to other Operating Systems, so much so that PC manufacturers were developing components around Windows’ capabilities and suddenly PCs were Windows machines. As big business began accepting the significance of computing, Microsoft started winning huge licensing contracts with all the major corporations in all sectors, but the Finance sector in particular, where Excel would be king, was having an exponential boom at this time. For big organisations, once you spent a fortune buying licences for the Operating System it only made sense to purchase the seamlessly integrated and carefully developed/tested apps to run on them; enter Excel, Word, PowerPoint and eventually Outlook. Fast forward to 2015 and we are firmly in the age of second generation corporate professionals who have developed much of their productivity skill sets around those particular Windows tools. While all the excellent tools have their place, Excel stands out and here are 8 reasons why you need to up your Excel game more than ever this year.

Compare 2 sets of data by letter or word & highlight mismatches [vba]

We analysts like to compare. If you ever want to keep an analyst busy, just give her 2-3 options. She won’t return to your desk until the cows come home. My wife uses this trick all the time. Picture this:

[In late 2013]
Me: I want to buy a new phone
She: Do you want Nexus 5 or Galaxy S5 or iPhone 5s?

Its late 2014 and I am not done comparing.

So today, let’s talk about an interesting comparison scenario.

Comparing by letter or word

Excel to the Next Level by Mastering Multiple Occurrences

Excel to the Next Level by Mastering Multiple Occurrences

This is a guest post by Sohail Anwar.

August 29, 1994. A day that changed my life forever. Football World Cup? Russia and China de-targeting nuclear weapons against each other? Anniversary of the Woodstock festival?

No, much bigger: Two Undertakers show up at WWE Summerslam for an epic battle. Needless to say: MIND() = BLOWN().

And thus begun one boy’s journey into understanding the phenomenon of Multiple Occurrences.

My journey continued, when just a few years later my grandfather handed me down a precious family heirloom: A few columns of meaningless data that I could take away and analyze in Excel. You may laugh but in the 90’s, every boy only wanted two things 1) Lists of pointless data and …
