Formula and method
Assumptions and limitations
This calculates basic EPS only; stock splits and changing share counts must already be reflected in weighted shares.
Worked example
With earnings available to common shareholders = 500000, weighted average common shares = 100000, basic eps is approximately 5.
What the result means
Use earnings after preferred dividends and weighted average shares. Diluted EPS requires a separate share adjustment.
