Market Sizing - Can you help me?

Hello Carol,

Market sizing questions are quite hard because there are some standard approaches but you have always to adapt them to the specific case.
Generally speaking, we can mention three different approaches:

• Top-down, that can be population based or householders based (e.g. chocolate bars or TVs sold in USA)
• Bottom-up, where you start from a particular situation and then you scale your estimation (e.g. Gas station in your country)
• Analytical, where you are asked to run an analysis based on "geometrical" considerations (e.g. golf balls fitting a Boeing 747)

In real cases you could also try to use more than one approach, one to obtain your estimation and the second one to do a sanity check of your result.

Feel free to text me if you want to discuss this further,
Luca

Hello!

Totally agree with Luca´s post.

Once you get them, market sizing exercises are actually easy, methodology is very very repetitive. However, until you reach that point, they seem scary. 

The only way to get comfortable with them is actually to practice as much as possible, both theorical isolated problems -you can find plenty in this forum- and integrated market sizing exersises embebed in cases. 

PM me if at a point you want a coach´s help with it, I have material for both types. 

Hope it helps!

Cheers, 

Clara

Hi Carol,

there are 4 main approaches for market sizing that help to cover basically all the situations (they are not the Cosentino’s ones, which are just a bad subset of the real ones). Most people forget at least one of them in their prep. Once you know the approaches, you won’t need much prep to master them. Please feel free to PM me for more info.

Best,

Francesco
