What Is Diluted EPS? Formula, Meaning and Example
Learn what Diluted EPS means, how it differs from basic EPS, and why potential share dilution matters to investors.
# What Is Diluted EPS?
Diluted Earnings Per Share (Diluted EPS) shows earnings per share after considering potentially dilutive securities that could become ordinary shares.
Examples include employee stock options, warrants and convertible securities.
The key question is:
> What could earnings per share look like if potentially dilutive securities became shares?
Basic EPS vs Diluted EPS
A simplified Basic EPS formula is:
Basic EPS = Profit attributable to ordinary shareholders ÷ Weighted average ordinary shares
Diluted EPS adjusts for potentially dilutive ordinary shares and, where applicable, related earnings adjustments.
In simple terms:
Diluted EPS = Adjusted earnings ÷ Adjusted weighted average shares
Simple Example
Suppose:
Basic EPS:
₹1,000 ÷ 100 = ₹10
Now suppose potentially dilutive securities add 5 crore shares under the applicable calculation.
Simplified diluted EPS:
₹1,000 ÷ 105 = ₹9.52
The potential additional shares reduce EPS.
Why Does Dilution Matter?
If the number of shares increases without a proportional increase in earnings, each share can represent a smaller portion of the company's earnings.
| Metric | Basic | Diluted |
|---|---:|---:|
| Profit | ₹1,000 cr | ₹1,000 cr |
| Shares | 100 cr | 105 cr |
| EPS | ₹10.00 | ₹9.52 |
What Can Cause Dilution?
Potential dilution can come from:
The exact accounting treatment depends on the instrument and applicable reporting rules.
Diluted EPS Is Not Always Lower
Potential securities are included when they are dilutive.
If including a potential security would increase EPS, it is generally considered anti-dilutive and is not included in diluted EPS.
Therefore, diluted EPS can be equal to basic EPS when there is no dilution.
Diluted EPS and P/E Ratio
A simplified P/E formula is:
P/E = Share Price ÷ EPS
Suppose a stock trades at ₹500.
Using basic EPS of ₹10:
P/E = 50x
Using diluted EPS of ₹9.52:
P/E ≈ 52.5x
The diluted figure can therefore give a more conservative earnings-based valuation.

Example: NIFTY Company
Imagine a hypothetical NIFTY company reports:
Basic EPS = ₹2,400 ÷ 120 = ₹20
Simplified diluted EPS = ₹2,400 ÷ 128 = ₹18.75
An investor should understand which EPS figure is being used for valuation.

Frequently Asked Questions
Is diluted EPS better than basic EPS?
Neither is universally better. Basic EPS reflects actual weighted-average ordinary shares, while diluted EPS considers potential dilutive shares.
Can diluted EPS equal basic EPS?
Yes, when there are no dilutive potential ordinary shares.
Does dilution mean the company is bad?
No. Employee equity or convertible securities can be legitimate parts of compensation or financing. The important issue is whether dilution is reasonable relative to growth and value creation.
Which EPS should I use for valuation?
Understand both. Diluted EPS is particularly useful when potential dilution is economically meaningful.
Final Thoughts
Diluted EPS helps investors understand how potential share issuance can affect earnings attributable to each share.
A company can increase total profit while EPS grows much more slowly if its share count expands significantly.
