What is Earnings Per Share?
Earnings Per Share (EPS) is a financial ratio that measures the portion of a company's profit allocated to each outstanding share of common stock. It's calculated by dividing net income by the weighted average number of outstanding shares during a specific period.
EPS serves as an indicator of company profitability and is fundamental to stock valuation. Higher EPS typically indicates better profitability, making it easier to compare companies of different sizes within the same industry.
How to Calculate EPS
Basic EPS Formula
Example Calculation:
- • Company XYZ Net Income: $10 million
- • Outstanding Shares: 2 million
- • EPS = $10,000,000 ÷ 2,000,000 = $5.00 per share
- • Each share earned $5.00 in profit during the period
Types of EPS
Basic EPS
- • Uses actual outstanding shares
- • Simpler calculation
- • Most commonly reported
- • Required by accounting standards
Diluted EPS
- • Includes potential share dilution
- • Accounts for stock options, warrants
- • More conservative measure
- • Better for valuation purposes
