Discover the difference between Basic EPS and Diluted EPS and understand how each metric reflects a company’s earnings strength and potential share dilution.
Earnings Per Share (EPS) is one of the most widely used profitability metrics among investors, analysts, and financial institutions. It indicates how much profit a company generates for each outstanding share. However, EPS is not a single measure—two variations exist: Basic EPS and Diluted EPS. Understanding the difference between the two is essential for analysing a company’s performance accurately, assessing shareholder value, and evaluating potential future dilution.
EPS measures how much net profit a company earns for each share of common stock.
It is calculated by dividing net income by the total number of shares.
EPS helps investors understand profitability on a per-share basis, making it easier to compare companies regardless of size.
Basic EPS represents the earnings available to each existing common share.
It uses the current outstanding shares and does not consider the possibility of future share dilution.
Profitability per existing share
Typically used for companies without convertible securities
Simple and straightforward profitability indicator
To calculate Basic EPS, follow these steps:
Start with Net Income from the income statement
Subtract Preferred Dividends (if any)
Divide the result by the weighted average number of common shares outstanding during the reporting period
This weighted average adjusts for share issues or buybacks within the year.
Diluted EPS accounts for all potential shares that could be created if convertible instruments were exercised. These potential additions to the share count are known as dilutive securities.
Stock options
Warrants
Convertible bonds
Employee stock options (ESOPs)
Diluted EPS = (Net Income – Preferred Dividends) / (Weighted Average Shares Outstanding + Dilutive Potential Shares)
Diluted EPS is almost always lower than Basic EPS because it assumes more shares are created, spreading profits over a larger base.
Here’s how to calculate Diluted EPS:
Compute Basic EPS
Identify all outstanding dilutive securities
Convert these securities into their share equivalents using the appropriate accounting method (e.g., treasury stock method, if relevant)
Add these potential shares to the current outstanding shares
Recalculate EPS with the higher share count
This provides a more conservative figure and reflects potential dilution.
Consider the following differences:
| Aspect | Basic EPS | Diluted EPS |
|---|---|---|
| Shares considered |
Only existing outstanding shares |
Existing shares + potential future shares |
| Reflects dilution? |
No |
Yes |
| Accuracy |
Less conservative |
More conservative and realistic |
| Use case |
Firms without convertible securities |
Firms with stock options, warrants, or convertible debt |
| Value |
Usually higher |
Usually lower |
| Investor perspective |
Indicates current profitability |
Shows future earnings impact due to dilution |
Diluted EPS provides a clearer view of risks, especially in companies that issue a large amount of stock-based compensation.
Consider the illustration given below,
Assume the following:
Net Income = ₹10,00,000
Preferred Dividends = ₹1,00,000
Weighted Average Shares = 2,00,000
Potential Dilutive Shares = 40,000
= (10,00,000 – 1,00,000) ÷ 2,00,000
= ₹4.50 per share
= (10,00,000 – 1,00,000) ÷ (2,00,000 + 40,000)
= ₹3.75 per share
As expected, Diluted EPS is lower because potential shares reduce the per-share profitability figure.
Here’s why each of these are important for investors:
Shows current profitability
Helps compare companies on equal footing
Used for basic valuation metrics such as P/E ratio
Indicates future dilution impact
Helps investors assess the effect of employee stock compensation
Required for companies with complex capital structures under accounting standards
Investors often prefer Diluted EPS because it is the more conservative and future-focused measure.
Earnings per share is one of the most widely used indicators of a company’s profitability. Understanding the difference between basic and diluted EPS helps assess how current earnings compare with potential future dilution. This distinction becomes especially important for companies that issue options, warrants, or convertible securities, as it affects long-term valuation and earnings quality.
Key points to remember:
Basic EPS reflects current profitability based on existing shares only.
Diluted EPS includes potential shares from convertibles and stock options.
Companies with convertible instruments must report both figures.
Diluted EPS is usually lower and offers a more conservative view.
Both metrics help evaluate earnings strength and dilution risk.

Basic EPS reflects earnings attributable to each currently outstanding share, while diluted EPS incorporates all potential shares from options, convertibles, and other dilutive instruments to show the impact of possible dilution.
Basic EPS is calculated using the formula:
(Net Income – Preferred Dividends) ÷ Weighted Average Shares Outstanding.
It represents earnings per existing share without considering any convertible securities.
Diluted EPS is derived by dividing (Net Income – Preferred Dividends) by the sum of Weighted Average Shares and all potential dilutive shares, offering a more conservative view of per-share earnings.
Diluted EPS tends to be lower because the inclusion of potential additional shares spreads the same earnings over a larger share base, reducing earnings per share.
The gap between the two metrics is influenced by the volume of outstanding stock options, convertible bonds, restricted stock units, and other instruments that could increase the total number of shares.
EPS is vital because it helps assess profitability, enables comparison across companies, supports valuation metrics, and highlights the impact of dilution on shareholder earnings.
