Answer:
Simply put, market share is a key indicator of a company's competitiveness. When a company increases its market share, this can improve its profitability. This is because as companies increase in size, they too can scale, therefore offering lower prices and limiting their competitors' growth.
You can determine a company's market share by dividing its total sales or revenues by the industry's total sales over a fiscal period.
It's important to calculate and understand market size for several reasons. First, entrepreneurs and organizations can use market sizing to estimate how much profit they could potentially earn from a new business, product or service. This helps decision-makers to decide whether they should invest in it.
