How it works
- Market cap = share price × shares outstanding
Rules:
- The share price must be more than $0, at most $1 billion.
- Shares outstanding must be more than 0, at most 10 trillion. A fraction of a share is allowed.
- The arithmetic is exact on the decimals you type. Money shows to the cent, with halves rounded up.
- A market cap too small to show as a number (for example a price of $1e-300 times 1e-300 shares) gives no answer.
Assumptions
- You type the price. The page fetches no market data.
- The share count is all shares outstanding, as one class.

Other questions people ask
What is market cap?
Market capitalization (market cap) is the value the stock market puts on a company's shares. It is the price of one share times the number of shares outstanding.
How do I calculate market cap?
Multiply the share price by the shares outstanding. 1.2 billion shares at $25.50 each is a market cap of $30.6 billion. 8,000 shares at $69.41 is $555,280.
Where do I find the number of shares outstanding?
Public companies report it on the cover of their annual and quarterly reports, and on the balance sheet or in its notes. Use the latest count, since buybacks and new issues change it.
Is market cap the same as what a company is worth?
No. Market cap is only the value of the shares at today's price. A buyer of the whole company would also take on its debt and get its cash, so measures such as enterprise value add debt and subtract cash.
Why does market cap change every day?
The share price moves whenever the stock trades, and the market cap moves with it. The share count changes only when the company issues or buys back shares.
What do large cap, mid cap and small cap mean?
They are rough size groups by market cap. Fund companies and index providers set their own dividing lines, so check the definition each one uses.
