The formula behind the result

The engine behind Market Share Calculator evaluates the inputs in a single pass — no hidden iterations or adjustments — so the market share you see is exactly what the formula produces for the values you entered.

Worked example: with your revenue of 500,000, total market revenue of 5,000,000, this market share calculation returns Market share: 10.0%. The same run reports You are #2–5 by size | relative size: 1 : 10.0.

The steps it follows:

Formula: Share = Your Revenue / Market Revenue × 100
$500,000 / $5,000,000
= 0.1000
Market share = 10.0%
