What is Market Share?

Market share is the proportional share of total market volume that belongs to the company when compared to the competitors in the same segment or category. Market share is usually in terms of revenue, customers or sales and is mostly expressed in percentage of the entire market accounted for by a company or brand vis-à-vis its competitors. The market share can be defined in terms of dollar share or unit share.

The term revenue market share (RMS) is the percentage the company has acquired as a percentage of total sales for the industry. RMS is also sometimes referred as dollar market share. Customer market share (CMS) is the percentage of customers in the market which a company has compared to its competitors. The volume market share can be calculated and compared on the basis of volumes of goods sold. RMS compares a company’s position compared to a competitor or the leading company.

Importance of Market Share

It is the indicator of a brand’s performance in the market relative to its competitor’s performance. There is no better indicator of a firm’s position in the market than the revenue share. If affirm manages to increase its revenue which is the top line, it not only increases its own sales but also gains a significant share.

Revenue alone cannot justify a firm’s grip in the market because at times, revenue may be higher the share may be low.

This means the product is being liked by customers but less so in comparison to its existing customers. It further means that the brand is letting go of a considerable customer base which is loyal to other brands.

The need for firms is to increase revenue and also keep an eye over its market share which is the real indicator of a firm’s growth and market position. Companies also use buying market share strategy by reducing prices to increase its business.

Consider the different example of market share:

1. Revenue

If a company X selling toothbrush has sales of $200,000 and if the entire market for toothbrush is $500,000, then the market share of X is:

$200,000 / $500,000 = 40% revenue market share

2. Volume

For example, if a company Y selling two wheelers has sold 500 two wheelers and the total number of two wheelers sold is 4000 then the market share of Y is:

500 / 4000 = 12.5%

3. Customer

If a company Z has 250,000 customers and all the customers in the particular industry are 1,000,000, then market share of Z is:

250,000 / 1,000,000 = 25%
