How to calculate based on total revenue
The first step in calculating your market share is to identify the period of time you want to evaluate. This can be a fiscal year, fiscal quarter, or a different time period of your choosing.
- Calculate your company's sales
Next, calculate your total sales for the period you identified. If you happen to span multiple industries (such as food and clothing), you would calculate this number separately for each industry, not based on your overall sales.
- Calculate total industry sales
After you’ve calculated your own sales, you next want to calculate the total sales for the entire market. This information is available in research reports and industry associations which are made publicly available. As mentioned above, be sure to calculate the total based on each separate industry.
Finally, divide your company’s total sales by the industry’s total sales. This will give you a decimal; multiply by 100 to convert to a percentage. This is your percentage of market share based on revenue.
How to calculate based on units sold
Same as above — the first step is to identify the period of time you want to review.
- Calculate your total number of units sold
Next, calculate the total number of units your company has sold within the identified fiscal period.
- Calculate the total number of units sold by the industry
Just like above, you can use research reports and industry associations to find the total number of units sold by the entire market.
Divide your company’s units sold by the total number of units sold by the whole industry. Be sure to multiply the decimal by 100 to calculate your percentage; this is your percentage of market share based on units sold.
Market share examples
It can be tricky to understand market share calculation at first glance. Accurately calculating your market share can help you position yourself to overtake the competition and become a long-lasting business with continued market growth.
Below are a few examples of how market share would be calculated in the real world:
Market share example: Total revenue
You own a bakery called Bake It Up. Your company earned $19 million of revenue in 2021. The bakery industry in total had $110 million of revenue for the year 2021.
If you divide 19 million by 110 million, you get a market share of 0.172, or 17.2%. Therefore, you own 17.2% of the bakery market share in 2021.
Market share example: Units sold
You own a company that builds speakers. In 2021, your company sold 1,133 speakers. The speaker industry in total sold 12,200 speakers in 2021.
Divide 1,133 by 12,200. You’ll see that your company had a market share of 0.09, or 9%, for units sold in the year 2021.
