This document summarizes a presentation by Ziya Boyacigiller on estimating market potential. It discusses defining the total addressable market (TAM), served available market (SAM), share of market (SOM), and total addressable demand (TAD). The key points are:
- TAM is the complete potential market. SAM is the segment you initially sell to based on resources or product fit.
- TAD is the portion of SAM that matches your target customer definition. This filters SAM down to who can be reached.
- SOM is the portion of TAD you aim to achieve, commonly specified as a percentage over time like 25% in the first year.

3. Sizing the Market Potential
Before you do a lot of work on a business
plan,
first, you should “stop and think”:
“Is it worth
it?”
4. Sizing the Market Potential
You need to agree that there is nothing better
you want to do with your time and money,
that the size of the opportunity fits your
expectations. (i.e. “opportunity cost”)
This leads you to estimate
the market size.
5. What is Your Market?
• First, define who your target customer will be.
• Write down the key characteristics that will define
your target customers. (If you do it right, you
should be able to hand this list to someone else,
and s/he should be able to find them successfully
for you.)
• Your customer is the one who will “hire” your
product/service to do a specific “job” for her/him.
6. What is TAM, SAM, SOM?
Scenario –
You market a widget for the cellphone
camera market. Your widget is only
used in phones that have cameras
embedded in them.
* Taken from Internet and modified...
7. WTH is TAM, SAM, SOM? *
Scenario - You market a widget for the
cellphone market.
TAM - Total Available Market
Who is your TAM in this scenario?
8. WTH is TAM, SAM, SOM? *
Scenario - You market a widget for the cellphone
camera market. Your widget is only used in phones
that have cameras embedded in them.
SAM - Served Available Market –
Who is your SAM in this scenario?
9. WTH is TAM, SAM, SOM? *
Scenario - You market a widget for the cellphone camera
market. Your widget is only used in phones that have
cameras embedded in them.
TAM - Total Available Market - In this example this would
be the total cellphone market.
SAM - Served Available Market - This would be cellphones
with cameras since your product is only used in them.
Obviously, TAM and SAM are a result of
definition… But, what is the need driving
businesses to define them?
10. How are we doing?
Widget 2004 2005 2006 2007
Unit Sales 100 125 180 220
AGR 25% 44% 22%
SOM
(vs TAM)
15% 17% 23% 25%
12. Not good…
Widget 2004 2005 2006 2007
Unit Sales 100 125 180 220
AGR 25% 44% 22%
SOM
(vs TAM)
15% 17% 23% 25%
SOM
(vs SAM)
50% 45% 45% 44%
AGR (5%) 0% (1%)
13. SOM vs SAM & TAM
SOM - Share of Market - this is just the
market share you have in your SAM, or in
this case your total volume versus the total
SAM volume.
As noted above, by comparing your SOM to
both your SAM and your TAM, you can get a
feel if you are really growing market
share, or just increasing volume along with
the total market growth.
14. One Word of Caution…
You can gather data in multiple forms:
• Units (Adet) : 5 each, 20 units, etc.
• Currency (Para) : $5, 20TL, etc.
• ASP (Average Selling Price) : Total Revenue : 2.5 TL/unit
Total Units
You need to look at all, to make a healthy
assessment of your business trends…
15. ENTRY INTO AN EMERGING MARKET

16. Drivers for Growth
• It is important to understand the underlying reasons for
growth (trends).
– Ex: cell phones telecom deregulation
– Ex: Instant messaging real time, low cost communication
• These should be taken to the limit they will reach in the future to
explain the economic tradeoffs behind the buying decision when
compared to substitute products.
– Ex: Will Internet access over satellite or cable win over time?
• Only then, can you be sure that the market will exist (not
disappear) when you are ready with your product/service.
– Ex: networking / dark fiber capacity
• You should also estimate the TAM and SAM growth rates
over time, when estimating your market size.

20. For Online Pet Stores,
It's Dog-Eat-Dog
Slim margins and a crowded market
point to a brutal shakeout
http://www.businessweek.com/index.html
“…But Fido should have chewed up a few of these online pet store business plans.
Because so many pet stores are rushing to the Web, the market is almost
certainly headed for a messy shakeout. Pet supplies have never been a lucrative
business. Operating margins are a razor-thin 2% at leading retailer PETsMART
and 4.5% at rival Petco. And the prospect of competitors willing to lose millions
to grab market share has investors skittish. “
22. TAM, SAM, TAD, SOM
TAM
world-wide, vehicle market
SAM
Turkey, sport utility
vehicle market
TAD
25%
SOM
TAD = SAM X 20% “A class” people
X 67% Car owner
X 80% Non-commercial use
X 30% Reads magazines
= SAM X 0.032 %
Total Addressable Market (TAD) is
the portion of the SAM that your
product/service can address. Start with the
definition (key characteristics - so you can sort
a mailing list using these characteristics to
develop an address list) of your target
customers and estimate the portion (percent)
of such customers in the SAM. These key
characteristics are like a filter that will let
through only those who are qualified to
be your customers.
SOM
Share of Market (SOM) commonly
known as “market-share” is the
portion of TAD you will own. This
is meaningful when a time is
specified together with the percentage
such as 25% within 1st
year…
SAM
Served Available Market is
the portion (segment) of
TAM that you decide to sell into,
at least initially. You do so,
because you do not have
sufficient resources to sell
into TAM, or your product
fits this segment only.
TAM
Total Available Market is
the complete universe of
all customers. This is the
market you can grow into
in time.
Note that SAM can be
the same as TAD if you
can reach (i.e. your “filter” addresses)
everyone in SAM
