The formulas
- Basic EPS = (net income - all preferred dividends) / basic shares
- Dividend per incremental share = convertible preferred dividends / shares on conversion
- If that is below basic EPS: diluted EPS = (net income - other preferred dividends) / (basic shares + conversion shares)
How it works
The if-converted method assumes convertible preferred stock was converted at the start of the period. The preferred dividends are added back to the numerator and the conversion shares are added to the denominator.
The test for dilution compares the dividend saved per new share against basic EPS. If each new share saves more than basic EPS, assuming conversion would raise EPS, so the security is antidilutive and left out.

Common questions
Are cumulative dividends included?
Yes, whether or not declared, if the preferred is cumulative.
What about convertible debt?
The same idea applies, but you add back after-tax interest. This tool covers preferred stock.
What if conversion happened mid-year?
Shares issued on an actual conversion enter basic EPS from the conversion date. The if-converted add-back then covers only the part of the year before conversion, so enter weighted figures.
