Market Share Calculator

Divide your revenue by total addressable market revenue to get market share.

About Market Share Calculator

The market share is the share of total market revenue that your revenue represents, expressed as a percentage. The same figure is also shown per 1,000 and as a "one in every N" odds statement, which is easier to reason about when the rate is very small. Absolute counts hide scale — a rate normalises the number so you can compare periods, channels or cohorts of different sizes, where higher is better.

Formula

Market Share

Market Share = Your revenue ÷ Total market revenue × 100
