Market Share Calculator
Estimate a company's share of its total market as a rough percentage from sales figures.
Formula
Market share = company sales divided by total market sales, multiplied by 100. This is a rough guide, since total market size is often estimated.
How it works
Divide the company's sales by the sales of the whole market over the same period. The percentage shows how big a slice the company holds. Market totals are often estimates, so treat the result as a rough guide rather than an exact fact.
FAQs
How do I find total market sales?
Industry reports, trade bodies and competitor estimates help, but for small niches the total is often an educated estimate.
Should I use units or money?
Either works, but do not mix them. Money share and unit share can differ when prices differ.
Is a small share bad?
Not necessarily. A small share of a huge market can still be a large, healthy business.
Estimates only, not financial advice. Check your figures before making a business decision.
