Can I use this calculator for private companies or startups?

No, the tool is designed for publicly traded companies with listed share prices and reported outstanding share counts. Private companies typically do not have publicly available market cap data.

Does the result include debt or other liabilities?

No, market capitalization only reflects the value of outstanding equity shares. It does not account for debt, cash, or other balance sheet items; enterprise value would be needed for a fuller picture.

How often should I recalculate the market cap?

For active investing decisions, recalculate whenever the share price changes significantly, as market cap fluctuates with real-time trading activity.

What categories define large-cap, mid-cap, and small-cap companies?

Large-cap companies generally have a market cap of $10 billion or more, mid-cap companies range between $2 billion and $10 billion, and small-cap companies are typically under $2 billion, though thresholds can vary by source.
