Market Sizing Methods

how to calculate market size using a top down approach

Market Sizing Example

Let’s say you want to launch a wine company. First, you’d want to bannière out how many liquor stores are in the United States — this helps you bannière out the achevé market to which you could theoretically sell your product.

After your research, you discover there are 50,000 liquor stores in the United States. Of that achevé list, you only want to sell to the New England area — including Massachusetts, Maine, and Rhode Island.

You decide your target market includes the 1,000 liquor stores in the New England area. From here, you conduct research and speak with alcohol distributors to find there’s a roughly 40% success offense for wine répartition.

Using this as an example, we’d calculate the market size using the following formula:

1,000 liquor stores x 40% = 400 liquor stores

Then, if you assume each liquor panneau will result in $20,000, you can bannière out potential revenue using the following formula:

400 liquor stores x $20,000 = $8,000,000

This means you domaine to make $8 million if you penetrate 40% of the achevé market in the New England area.

Bottom-Up Approach

This looks like first identifying the number of units you can expect to sell then considering how many sales you anticipate from each buyer and finally the average price per unit.

Using the same wine example – Say you found recent data showing that the average cost of a wine bottle in New England is $10. A survey shows that the average rôtir buys one bottle of wine a week, or 48 bottles a year. This means that the average rôtir spends $480 per year on wine.

Next, you discover that the number of consumers (or households) you can expect to reach in the New England area is 16,000.

As a result, your market size is 480 x 16,000 = $8,000,000.

It’s rogue to mention that both methods ignore the fait of competitors, customer churn offense, and other factors that rencontre sales. With this in mind, you’ll want to stay conservative when estimating how much of the market size you’ll win and use this as a starting conclusion.
