Market Cap vs. Enterprise Value: What's the Difference?
By MarketCapLens · Updated July 16, 2026 · 5 min read
Market capitalization and enterprise value both try to answer "what is this company worth?" from different angles. Market cap values the equity the shareholders own. Enterprise value estimates what it would cost to buy the whole business, debt and all.
Key takeaways
- Market cap = share price × shares outstanding (the value of the equity).
- Enterprise value = market cap + total debt − cash.
- Two companies with equal market caps can have very different enterprise values.
- Market cap is best for sizing and ranking; enterprise value is best when debt and cash matter.
The two formulas
Market cap = share price × shares outstanding
Enterprise value = market cap + total debt − cash & equivalents
Market cap is what the market says the shareholders' stake is worth. Enterprise value then adjusts for the balance sheet: it adds debt, because an acquirer inherits it, and subtracts cash, because an acquirer effectively gets it back.
A quick example
Picture two companies that both carry a market cap of $100 billion:
| Company | Market cap | Debt | Cash | Enterprise value |
|---|---|---|---|---|
| A | $100B | $0 | $20B | $80B |
| B | $100B | $40B | $5B | $135B |
Same market cap, very different enterprise values. Company A is cheaper to buy outright than its market cap suggests, thanks to its cash. Company B is pricier, because a buyer takes on its debt. Market cap alone hides all of that.
When to use each measure
Reach for market cap when you want to compare company size quickly or rank companies (as the main ranking does), gauge how much a stock will move a market-cap-weighted index, or talk about the value that belongs to shareholders.
Reach for enterprise value when you are comparing companies with very different debt loads, pricing a business the way an acquirer would, or building valuation multiples that shouldn't be skewed by how a company is financed. Enterprise value pairs naturally with operating figures like EBITDA, while market cap pairs with equity figures like earnings (the familiar P/E ratio).
Which one is "right"?
Neither, on its own. They measure different things. Market cap is the right tool for sizing and ranking companies, which is why it anchors MarketCapLens. Enterprise value is the right tool when debt and cash change the story. Knowing which lens you are using keeps your comparisons honest. New to the basics? Start with What Is Market Capitalization?

Frequently asked questions
- What is the difference between market cap and enterprise value?
- Market cap is share price times shares outstanding — the value of the equity. Enterprise value adds debt and subtracts cash to estimate the cost of buying the whole business.
- When should I use enterprise value instead of market cap?
- Use enterprise value to compare companies with very different debt or cash levels, or when you are thinking like an acquirer. Use market cap to gauge or rank a company's size.
