What Is Free Float?
Free float (or public float) refers to the number of a company’s shares that are freely traded in the market. These shares are not held by:
- Company insiders (founders, executives)
- Major shareholders (governments, institutions with controlling stakes)
- Restricted shares (locked due to regulations)
Example:
If a company has 100 million shares in total, but:
- 30 million are held by insiders
- 20 million are owned by the government
Then, the free float is 50 million shares (100M – 30M – 20M).
Why Does Free Float Matter in Stock Trading?
Free float affects:
- Stock Liquidity – More free float means easier buying/selling.
- Price Volatility – Low free float stocks can swing sharply.
- Index Weighting – Major indices (S&P 500, Nifty 50) use free float for calculations.
- Market Manipulation Risk – Stocks with low free float are easier to manipulate.
Real-World Example:
- Tesla (High Free Float) – Easy to trade, less volatile.
- Small-Cap Penny Stocks (Low Free Float) – Can spike or crash quickly.
How to Calculate Free Float Manually
The formula is simple:Free Float=Total Shares Outstanding−Free Float=Total Shares Outstanding−
Step-by-Step Calculation:
- Find Total Shares Outstanding – Check the company’s balance sheet or financial websites like Yahoo Finance.
- Identify Restricted Shares – Look for:
- Insider holdings (SEC filings, annual reports)
- Government or strategic investor stakes
- Locked shares (employee stock options, IPO restrictions)
- Subtract Restricted Shares – The remaining number is the free float.
Example Calculation:
| Item | Shares (Millions) |
|---|---|
| Total Shares Outstanding | 100 |
| Insider Holdings | 20 |
| Government Holdings | 10 |
| Free Float | 70 |
So, 70 million shares are freely tradable.

Why Use a Free Float Calculator?
1. Saves Time
No need to dig through financial reports manually.
2. Reduces Errors
Automated calculations avoid human mistakes.
3. Helps in Stock Selection
- High free float (70%+) → Good for long-term investors.
- Low free float (<30%) → Risky, prone to volatility.
4. Useful for Index Investors
Indices like S&P 500 and Nifty 50 use free float for weighting.
Limitations of Free Float Analysis
1. Changes Over Time
- New insider buying/selling affects free float.
- IPOs and share buybacks alter numbers.
2. Not the Only Factor
A stock with high free float can still be risky if fundamentals are weak.
3. Doesn’t Account for Dark Pools
Some shares trade in private markets, not reflected in free float.
Free Float vs. Market Cap: What’s the Difference?
| Factor | Free Float | Market Cap |
|---|---|---|
| Definition | Shares available for trading | Total value of all shares |
| Calculation | Total shares – locked shares | Share price × total shares |
| Use Case | Measures liquidity | Measures company size |
Example:
- Company A:
- Total shares: 1 million
- Free float: 600,000 (60%)
- Share price: $10
- Market cap: $10 million
- Free float market cap: $6 million
