Financial Ratios: Definition, Types, and Examples

Financial ratios are numerical metrics calculated from a company's balance sheet, income statement, and cash flow data.

They help Indian investors assess a stock's valuation, profitability, debt levels, and operational efficiency without reading full annual reports. Key ratios include PE, ROE, ROCE, D/E, Current Ratio, and EPS.

This guide kind of walks you through the ratios that matter most, what each metric truly measures, and how you can use them to judge any NSE or BSE-listed company, step by step.

For the fundamentals behind ratio reading, see this guide to financial ratio analysis definition, types, examples, and uses.

What Are Financial Ratios and Why Do They Matter?

Financial ratios are a kind of numbers, calculations made from audited financial figures that are published by each listed company on NSE and BSE. Under SEBI’s LODR (Listing Obligations and Disclosure Requirements) rules, these listed entities have to publish their quarterly financial results within 45 days after each quarter ends.

No paid subscription is required; all figures are freely available on the balance sheet and income statement filings on exchange websites.

Ratios work by stripping away company size and making any two businesses directly comparable. A Rs 500 crore company and a Rs 50,000 crore company can be compared fairly using the same ratio framework.

Valuation Ratios : Is the Stock Priced Fairly?

Valuation ratios compare a stock's market price to an underlying financial metric. They answer one question: what are you paying for what you get?

PE Ratio (Price to Earnings)

Formula: PE = Market Price per Share / Earnings Per Share (EPS)

The PE ratio tells you how many rupees the market is willing to pay for every Rs 1 of a company's earnings. A PE of 20 means investors are paying Rs 20 for every Rs 1 of profit.

Indian context: The Nifty 50 has historically traded in a PE range of 16x to 22x, with a long-term average of approximately 18x (Source: NSE Historical Data). A stock trading below its sector's median PE may be undervalued but only if earnings are growing, not falling.

Limitation: PE is meaningless for loss-making companies, cyclical businesses at earnings troughs, or sectors like banking where earnings are structured differently. Always compare PE within the same sector.

Price to Book Ratio (P/B)

Formula: P/B = Market Price per Share / Book Value per Share

The P/B ratio is meant to look at how much the market pays for a company’s shares compared to what the company’s net assets are, really, worth on paper. So a P/B below 1 kinda means the stock is trading beneath its book value, which could point to it being potentially undervalued  but this is not a conclusion by itself, it takes a closer look and some checking.

Where it works best: Banking, manufacturing, NBFCs, and capital-intensive businesses. P/B is less useful for IT and FMCG companies where value comes from intangible assets not reflected in book value.

EPS (Earnings Per Share)

Formula: EPS = Net Profit / Total Shares Outstanding

EPS is basically the rupee earnings the company grabs per share, you know. When EPS is rising for 5 straight years and that pattern shows up in each quarterly BSE filing , it reads like a better quality signal than leaning on just one year’s single number. If EPS is flat or even moving down while the stock price keeps climbing. 

Profitability Ratios:  Is the Business Generating Returns?

Profitability ratios measure how efficiently a company converts revenue and capital into profit.

ROE (Return on Equity)

Formula: ROE = Net Profit / Shareholders' Equity x 100

ROE measures how much profit a company generates for every Rs 100 of shareholder money. An ROE above 15% is generally considered healthy for non-financial Indian companies.

Critical trap : ROE can be manipulated by debt. A company that borrows heavily increases its assets without proportionally increasing equity. This mathematically inflates ROE even if the underlying business is not performing well. Example: If Company A earns Rs 10 on Rs 100 equity, ROE is 10%. If it borrows Rs 200 more and earns Rs 30 total, ROE jumps to 30%  but debt has tripled.

Rule: Always check ROE alongside D/E ratio. High ROE + High D/E = debt-inflated figure. High ROE + Low D/E = genuine business quality.

ROCE (Return on Capital Employed)

Formula: ROCE = EBIT / (Total Assets - Current Liabilities) x 100

ROCE is a more reliable profitability measure than ROE for non-financial companies because it measures returns on total capital both equity and debt. It cannot be inflated by borrowing more.

Benchmark: ROCE must be higher than the company's cost of borrowing. With Indian bank lending rates typically between 9% and 12%, a company with ROCE below 10% is essentially borrowing to lose money.

Multibagger signal: Rising ROCE over 3 to 5 consecutive years from 12% to 20% to 28%  is a classic signal that a business is compounding efficiently. This is the pattern that precedes major stock re-ratings in the Indian market.

Leverage and Debt Ratios:  How Much Risk Is the Company Carrying?

Debt ratios measure how much of a company's operations are funded by borrowed money versus shareholder capital.

Debt to Equity Ratio (D/E)

Formula: D/E = Total Debt / Shareholders' Equity

D/E shows how much debt a company carries for every Rs 1 of equity. For most non-financial Indian companies, a D/E below 1 is considered safe. Above 2 warrants scrutiny. Above 3 is a red flag  unless the business has very predictable, contracted cash flows.

Sector exception: This benchmark does NOT apply uniformly across all sectors. Banks and NBFCs use depositor and borrowed funds as raw material  a D/E of 5 to 7 is normal and expected for NBFCs. Applying a D/E below 1 standard to a bank would incorrectly label every healthy bank as risky.

Interest Coverage Ratio (ICR)

Formula: ICR = EBIT / Interest Expense

ICR measures how many times a company can pay its annual interest expense using its operating profit.

• ICR above 3: Comfortable. Company has a significant buffer.

• ICR between 1.5 and 3: Acceptable, monitor closely.

• ICR below 1.5: Danger zone. Any revenue decline could cause default.

Pair D/E with ICR always. A company with D/E of 1.5 but ICR of 5 is safer than a company with D/E of 0.8 but ICR of 1.2. The second company earns just barely enough to service even its small debt.

Liquidity Ratios: Can the Company Pay Its Short-Term Bills?

Liquidity ratios check whether a company can meet obligations due within the next 12 months.

Current Ratio

Formula: Current Ratio = Current Assets / Current Liabilities

A Current Ratio above 1 means the company has more short-term assets than short-term liabilities. A ratio between 1.5 and 2.5 is considered healthy for most Indian manufacturing and trading companies.

Real data reference: Britannia Industries Limited reported total current assets of Rs 4,849 crore and total current liabilities of Rs 4,084 crore as of March 31, 2024, giving a current ratio of approximately 1.2 (Source: Britannia Industries Annual Report, BSE filing, FY24). This is below the 1.5 benchmark but Britannia is a cash-generative FMCG company with strong brand power and predictable collections, making the ratio acceptable in context.

This illustrates the key rule: a ratio is only meaningful in context.

Sector-Wise Ratio Benchmarks for Indian Investors

This is the single most important section competitors miss. The same ratio has a different acceptable range in different sectors. Applying a universal benchmark without sector context is one of the most common mistakes Indian retail investors make.

Benchmark ranges sourced from sector filings on NSE and BSE, SEBI LODR disclosures, and CARE Ratings sector reports. Last updated: June 2026.

Key rule: Never compare a pharma stock's D/E to a banking stock's D/E. Always benchmark within the same sector. The ratios above are indicative ranges  individual companies may operate outside these ranges for valid strategic reasons.

How to Read Financial Ratios in the Right Order: 5-Step Checklist

Most beginners start with PE ratio. That is the wrong starting point. PE is a valuation metric it tells you what price you are paying. Before asking whether the price is right, you need to know whether the business is sound. Here is the correct sequence:

Step 1: Check Debt First (D/E + ICR). Is the company carrying dangerous levels of debt? A company drowning in debt is not investable, regardless of how attractive the PE looks. Check D/E and ICR together.

Step 2: Check Profitability (ROCE, then ROE). Is the business earning more than its cost of capital? ROCE first then ROE. Cross-check ROE with D/E to verify it is not debt-inflated.

Step 3: Check Valuation (PE, then P/B). Only after confirming the business is solid and profitable, check whether the current market price is reasonable. Compare PE and P/B against sector peers on NSE, not against an absolute number.

Step 4: Check Liquidity (Current Ratio) Can the company meet its near-term obligations? A ratio below 1 in a capital-intensive sector requires deeper investigation.

Step 5: Confirm EPS Trend Over 5 Years. A rising EPS over 5 years confirms the business is growing, not just appearing profitable in a single quarter. All EPS data is available in BSE quarterly result filings free of charge.

Red Flags in Financial Ratios:  What Indian Investors Must Watch For

Strong-looking numbers can hide serious problems. Three specific ratio-based red flags that Indian investors must check:

Red Flag 1: High ROE + High D/E 

ROE above 20% alongside D/E above 2 often signals that profits are being engineered through leverage, not genuine business strength. Check ROCE to verify. If ROCE is significantly lower than ROE, debt is doing the heavy lifting.

Red Flag 2: ROCE Declining Over 3 Consecutive Years 

A company with ROCE falling from 22% to 17% to 12% over three years is destroying capital. This pattern  available clearly in the financials section of NSE or BSE filings  frequently precedes earnings downgrades, management changes, and sharp stock price corrections.

Red Flag 3: Falling Current Ratio + Rising Short-Term Borrowings

 When a company's current ratio drops below 1 at the same time that short-term borrowings increase, it is often a sign that the company is funding operations with expensive short-term debt. This liquidity squeeze has preceded several high-profile Indian corporate defaults.

How to Find Financial Ratios of Any Indian Stock

Every ratio in this guide is calculable for free from publicly available data.

Where to find the data:

• BSE website: Company filing page under Financials > Quarterly Results

• NSE website: Same data under Company Info > Financial Results

• SEBI mandates all listed companies to publish quarterly results within 45 days of quarter-end under LODR regulations

Faster option: Use the stock screener to filter all NSE-listed stocks by PE, ROCE, D/E, Current Ratio, and more in under 30 seconds without opening a single annual report.

Conclusion

Financial ratios work because they reduce hundreds of pages of audited data to a handful of comparable numbers. PE tells you what you pay. ROE and ROCE tell you what the business earns. D/E and ICR tell you how much risk you take. The current ratio tells you if short-term trouble is coming. Used in the five-step sequence above with sector-appropriate benchmarks, these ratios form the core of any sound fundamental analysis framework for Indian stocks.

No ratio works in isolation. No ratio is sector-neutral. And no ratio replaces reading the actual filings but they give you the right questions to ask before you do.
