Basic earnings per share (EPS) and diluted EPS are used to measure the profitability of a company. Basic EPS is calculated using the weighted average of outstanding shares of equity. Diluted EPS includes dilutive convertible shares in its calculation, such as employee stock options, warrants, and convertible debt. Both are important for the fundamental analysis of a company.
Key Takeaways
-
Basic EPS reflects earnings based only on outstanding shares, while diluted EPS accounts for all potential share conversions affecting profitability.
-
Diluted EPS provides a more conservative measure, especially for companies with stock options, warrants, convertible bonds, or other dilutive instruments.
-
Diluted EPS is always equal to or lower than basic EPS because added potential shares reduce earnings per share.
-
Evaluating both EPS types gives a clearer understanding of financial health, particularly for companies with complex capital structures and future dilution risks.
Basic EPS vs Diluted EPS Calculation:
EPS can be calculated with the given formula: Basic EPS = (Net income − Preferred dividend) / Weighted average of outstanding common shares
For example, if a company earned a net profit of Rs 50 crore and the total outstanding shares were 1 crore, then the EPS would be Rs 50 per share. However, this formula poses a problem. Basic EPS takes into account only outstanding shares. A company may have other potential sources of dilution of equity. For instance, a company may have issued warrants that, when exercised, will lead to dilution of equity. Alternatively, the company may have issued convertible debentures, which, if converted, could also increase the number of outstanding shares. All such potential sources of equity dilution are taken into account while calculating diluted EPS. Thus, diluted EPS gives a clear picture of a company’s actual earnings per share.
Earlier, it was not essential for companies to declare diluted EPS. However, now we can see the diluted EPS in every financial statement of the company.
Diluted EPS is calculated with the formula:
Diluted EPS = (Net income + post-tax interest on convertible debt) / weighted average common shares + potential common shares
To calculate diluted EPS, it is necessary to identify all potential shares, such as any financial instrument that can result in more shares in the future. Potential ordinary shares include the following:
1. Stock options and warrants
2. Convertible bonds
3. Convertible preferred shares
Stock options are employee benefits that allow the buyer to purchase common shares at a predetermined time and price. Convertible preferred shares and convertible bonds are similar and can be converted into common shares at the time and rate mentioned in their contract.

Basic EPS vs Diluted EPS Application:
EPS is important in calculating the P/E ratio, which is used for the valuation of the company. Hence, the precise calculation of EPS is important. Diluted EPS is more scientific than basic EPS.
For fundamental analysis, diluted EPS is more effective as it includes the impact of all potential equity diluters. This ensures the company’s EPS is in line with future expansion. Hence, this is more important for the P/E calculation.
Basic EPS serves the purpose on most occasions except when there is significant dilution in a company. Then diluted EPS makes more sense.
Basic EPS vs Diluted EPS Differences:
Some of the key differences between basic EPS and diluted EPS are:
1. Although very suitable, basic EPS is not a good measure of the company’s financial health. Diluted EPS is a stricter approach to knowing how a company is doing financially
2. Basic EPS is a simple measure compared to diluted EPS
3. Basic EPS is used for companies with a simple capital structure, while diluted EPS is used for companies with more complex capital structures. Most large companies have potential diluters, and hence, for them, diluted EPS is more meaningful
4. Diluted EPS is always lower: This is almost correct, but needs a nuance. Diluted EPS is always lower than or equal to basic EPS. It is never higher. If a company has no dilutive securities (or if the potential securities are anti-dilutive and thus ignored), then the basic EPS and the diluted EPS will be identical.
5. Basic EPS does not consider the effect of equity dilution on profit, while diluted EPS does

Example of Earnings Per Share (EPS) vs Diluted EPS
Understanding basic vs diluted EPS with a real-life example is easier. Assuming that a company has 1 crore shares outstanding and its net profit is 10 crore. The basic EPS is ₹10 per share. The company, however, has 20 lakh shares in potential stock options and convertible securities as well. Once these are included, the diluted EPS will reduce to about 8.33 per share as the total number of shares goes up to 1.2 crores.
This illustrates the fundamental difference in basic vs diluted EPS: Basic EPS shows earnings on shares outstanding, whereas diluted EPS shows earnings on all possible conversions of shares. Diluted EPS offers a more conservative and realistic view of a company’s earnings power, especially when assessing firms with significant employee stock options or convertible debt.

Conclusion:
Ascertaining both basic EPS and diluted EPS helps to see the financial health of the company more accurately. It is always better to compute both if the company’s capital structure is complex.
