In today’s stock market, not all shares are actually available for trading. Understanding which shares truly impact the market can give investors a big advantage.
Free float capital market capitalisation means the total market value of a company’s shares that are freely available for trading in the stock market. It does not include shares held by promoters, government entities, and strategic investors. The reason behind this is that these shares are usually not traded regularly. In other words, it shows how much of the company is actually available for investors to buy and sell in the market. 

Let's say a company has 10 million shares, but from it, only 6 million are available for public trading; then the free float calculation will consider only those 6 million shares. With the help of this method, investors can easily understand the real market participation and the liquidity of the stock.

Free Float Market Capitalisation Formula

The free float market capitalisation formula is very simple:

Formula: Free Float Market Cap = Share Price * (Outstanding Shares – Restricted Shares)

In the above formula, restricted shares include promoter holdings and strategic investments.

This formula adjusts the total market value by removing shares that are not actively traded

Example 
 

The Free Float Market Cap will be ₹500 × 6 crore = ₹3000 crore. This helps investors clearly understand the actual tradable value of a company and make better and more informed investment decisions in the market.
