Note
This is not investment advice. It is a simplified model: it applies the displayed standard formula to the figures you entered, ignores taxes, fees, currency effects and credit risk, and assumes cash flows arrive exactly as scheduled. Real markets do not behave that way, and past or projected returns do not guarantee future results. Check the assumptions and consult a licensed adviser before acting on any figure.

How is market capitalization calculated?+
Market cap is the current share price multiplied by the total number of shares outstanding, giving the total market value of a company's equity as priced by investors right now.
Does market cap represent what it would cost to buy the entire company?+
Not exactly — buying every outstanding share typically requires paying a premium above the current price (to convince shareholders to sell), and an acquirer may also need to account for the target's debt, so market cap is a starting reference point, not a full acquisition cost.
What are the typical size categories based on market cap?+
Common classifications are large-cap (often above $10 billion), mid-cap (roughly $2-10 billion), and small-cap (roughly $300 million-$2 billion), though exact thresholds vary by source and change over time.
Why does market cap change even when the number of shares stays the same?+
Market cap moves with the share price, which fluctuates continuously based on trading activity, so it changes throughout each trading day even without any change in shares outstanding.
How is market cap different from enterprise value?+
Market cap only reflects the value of equity (what shareholders own), while enterprise value adds debt and subtracts cash to represent the total value of the underlying business, which matters more for comparing companies with different capital structures.
