Revenue vs. Commission growth – Getting the message across [BYOD]

Published on Feb 17, 2015 in Analytics, Charts and Graphs

Situation: Our commissions are growing way faster than revenues
Let’s say you are looking revenues & sales commissions of your company for last few years. The data looks like this:

revenue-growth-vs-commission-growth-data

And you want to highlight the fact that commissions are growing faster than revenues.

So you plot YoY growth rates for revenues & commissions.

Problem: The chart of YoY growth rates is not convincing

Take a look at the chart. It doesn’t convey the message that we want. At best it says “revenue growth is less than commission growth”

revenue-growth-vs-commission-growth-problem

How to convey the message “Commission growth is a problem for us”?

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.

Create a line chart with bands [tutorial]

Here is an interesting scenario.

Imagine you are responsible for customer satisfaction at ACME Inc. Every month you track customer satisfaction rate for the 3 products you sell which are conveniently named Product A, B & C.

You also have bands for the satisfaction rating.

  • Rating of 85% or below is Average
  • Rating between 85% & 95% is OK
  • Rating above 95% is good

At the end of the year, you want to visualize the ratings for last 12 months for 3 products along with bands.

Something like above.

Unfortunately, there is no “Insert Banded line chart” button in Excel. So what to do?

That is what we will learn today. Ready?

Use Indexed charts when understanding change [Charting Techniques]

Use Indexed charts when understanding change [Charting Techniques]

Today, lets talk about indexing, a technique used to compare changes in values over time.

What is indexing?
Lets say you want to compare prices of Gold & Coffee over last few years. Gold price in 2011 (oct) is $1,655 per ounce. And now (sept 2012) it is $1,744. Like wise, Silver price in 2011 is $32.06 and in 2012 it is $33.61. How do we compare such diverse numbers?

Enter indexing.

First we need to calculate price of Gold and Silver in 2012 assuming their starting price is 100. This can be done with simple arithmetic.

Now, we can easily compare the prices. Looking at the indexed prices, we can conclude that both Gold & Silver prices have gone up by similar percentage (~5%).
