Expert Tip

Companies are classified by size based on market cap: Mega-cap ($200B+), Large-cap ($10B-$200B), Mid-cap ($2B-$10B), and Small-cap ($300M-$2B).

How this Calculator Works

This calculator computes a company's market capitalization, representing the total dollar value of its outstanding shares of stock. It is the primary metric used to classify companies into mega-cap, large-cap, mid-cap, and small-cap groups. Investors use it to assess firm size.

Formula & Methodology

Market Capitalization = Stock Price * Outstanding Shares - Stock Price is the current market price of a single share of stock. - Outstanding Shares is the total number of shares issued by the corporation.

Step-by-Step Calculation Example

Here is a step-by-step example showing how the calculations are performed:

A company's stock trades at $50 per share, and there are 200,000,000 outstanding shares. 1. Multiply stock price by outstanding shares: $50 * 200,000,000 = $10,000,000,000 ($10 billion). Result: The market capitalization of the company is $10,000,000,000 ($10 billion).

FAQ

What is WACC and why is it crucial for equity valuation?
Weighted Average Cost of Capital (WACC) represents a company's required average return on debt and equity capital. It is used as the hurdle rate to discount future cash flows in DCF valuation models.
How does stock Beta measure systematic risk?
A stock beta of 1.0 means price volatility matches the broader market index. Beta > 1.0 indicates higher volatility, while Beta < 1.0 reflects lower systematic volatility.
Should valuation multiples be evaluated in isolation?
No. Valuation ratios (P/E, EV/EBITDA, P/B) should always be benchmarked against industry peer groups, historical trading averages, and expected earnings growth (PEG ratio).
