Learn the most important financial ratios used in stock analysis including ROE, ROCE, EPS, P/E ratio, and debt ratios. Beginner-friendly guide to fundamental investing.

Introduction

Reading financial statements like:

• Balance Sheet

• Profit & Loss Statement

• Cash Flow Statement

is essential for stock analysis.

But raw numbers alone are not enough.

Investors use financial ratios to interpret company performance quickly.

Financial ratios help answer questions like:

• Is the company profitable?

• Is the company efficient?

• Is the company overburdened with debt?

• Is the stock expensive or cheap?

In this article we will understand the most important fundamental ratios every investor should know.

What Are Financial Ratios?

Financial ratios are mathematical comparisons between different financial numbers.

They help simplify financial statements.

For example:

Profit ÷ Equity = Return on Equity

This tells us how efficiently a company uses shareholders’ money.

Why Financial Ratios Matter

Ratios help investors:

✔ Evaluate company performance
✔ Compare companies in the same industry
✔ Identify strong businesses
✔ Avoid financially weak companies

Professional investors rely heavily on ratio analysis.

1️⃣ Earnings Per Share (EPS)

EPS is one of the most widely used profitability metrics.

Formula

EPS = Net Profit / Total Outstanding Shares

Example

Company profit = ₹100 crore
Total shares = 10 crore

EPS = ₹10

This means the company earned ₹10 per share.

Why EPS Matters

Higher EPS generally indicates:

✔ strong profitability
✔ growing earnings
✔ better shareholder returns

Investors prefer companies with consistently rising EPS.

2️⃣ Price to Earnings Ratio (P/E Ratio)

The P/E ratio tells us how expensive a stock is relative to its earnings.

Formula

P/E Ratio = Market Price per Share / EPS

Example

Share price = ₹500
EPS = ₹25

P/E = 20

This means investors are paying ₹20 for every ₹1 of earnings.

What P/E Ratio Indicates

High P/E → growth expectations
Low P/E → undervaluation or slow growth

Important Note

Always compare P/E with:

• Industry average

• Company’s historical P/E PROFIT & LOSS Vs. CASH FLOW

3️⃣ Return on Equity (ROE)

ROE measures how efficiently a company generates profit from shareholders' capital.

Formula

ROE = Net Profit / Shareholder Equity

Example

Net Profit = ₹100 crore
Equity = ₹500 crore

ROE = 20%

This means the company generates ₹20 profit for every ₹100 invested by shareholders.

What Is a Good ROE?

Generally:

15%+ → good
20%+ → excellent

Companies with high ROE create long-term wealth.

4️⃣ Return on Capital Employed (ROCE)

ROCE measures how efficiently the company uses both debt and equity capital.

Formula

ROCE = EBIT / Capital Employed

Capital Employed = Total Assets – Current Liabilities

Why ROCE Is Important

ROCE shows:

 overall business efficiency
capital productivity

High ROCE companies usually have:

• strong competitive advantage

• efficient management

Good ROCE Benchmark

15% or higher is generally considered strong.

5️⃣ Debt to Equity Ratio

This ratio measures financial leverage.

Formula

Debt to Equity = Total Debt / Shareholder Equity

Example

Debt = ₹200 crore
Equity = ₹400 crore

Debt-Equity = 0.5

What It Indicates

Low ratio → safer balance sheet
High ratio → higher financial risk

Ideal Range

Below 1 is generally considered safe (depends on industry).

Capital intensive sectors like infrastructure may have higher ratios.

6️⃣ Interest Coverage Ratio

This ratio measures the company’s ability to pay interest on its debt.

Formula

Interest Coverage = EBIT / Interest Expense

Example

EBIT = ₹200 crore
Interest = ₹50 crore

Interest Coverage = 4

What It Means

Company can pay interest 4 times over.

Higher ratio = safer company.

Safe Level

Above 3 is generally comfortable.

7️⃣ Profit Margin

Profit margin shows how much profit a company earns from sales.

Formula

Profit Margin = Net Profit / Revenue

Example

Revenue = ₹1000 crore
Net Profit = ₹150 crore

Profit Margin = 15%

Why Profit Margin Matters

Higher margins indicate:

pricing power
operational efficiency
strong business model

8️⃣ Free Cash Flow (FCF)

Free cash flow measures how much cash remains after operating expenses and capital expenditure.

Formula

FCF = Operating Cash Flow – Capital Expenditure

Why Investors Love Free Cash Flow

Companies with strong FCF can:

 pay dividends
expand business
reduce debt
invest in growth

Strong free cash flow companies are usually financially stable.

How Investors Use Ratios Together

No single ratio tells the full story.

Investors combine multiple ratios.

Example of a strong company:

 ROE above 20%
ROCE above 18%
Debt-equity below 0.5
Growing EPS
Positive free cash flow

Such companies often become long-term compounders.

Example of Ratio Analysis

Suppose a company shows:

ROE = 22%
ROCE = 19%
Debt-Equity = 0.3
EPS growth = 15%
Positive free cash flow

This indicates a financially strong business.

Red Flags Investors Should Watch

 Very high debt
Declining ROE
Negative cash flow
Falling profit margins
Very high P/E compared to industry

These may signal risk.

Key Takeaways

 Financial ratios simplify company analysis
EPS shows profitability per share
P/E indicates valuation
ROE measures shareholder returns
ROCE measures capital efficiency
Debt ratios measure financial risk
Free cash flow indicates financial strength

Using these ratios together helps investors identify strong companies.

Final Thoughts

Successful investing is not about chasing tips.

It is about understanding businesses.

Financial ratios provide a powerful toolkit for evaluating companies.

Before investing in any stock, always analyze:

 profitability
efficiency
valuation
debt
cash flow

These metrics can help you avoid weak companies and find long-term winners.
