EPS is calculated using this formula: Net Income - Preferred Dividends / Weighted Average Common Shares Outstanding

There are two main types of EPS:

  1. Basic EPS
  • Uses only outstanding common shares
  • Simpler to calculate
  • Best for companies that rarely issue new shares
  • Excludes company-owned shares
  1. Diluted EPS
  • Includes potential shares from convertible securities
  • More complex calculation
  • Accounts for stock options and convertible bonds
  • Provides a more conservative estimate
