The Financial Pulse - Financial Ratios

Financial statements give you the data, but Financial Ratios give you the story. A company might have ₹100 Crores in profit, but is that good? If they used ₹1,000 Crores of capital to get it, it’s a disaster. If they used ₹200 Crores, it’s a triumph.

Ratios allow us to compare companies of different sizes and industries on a level playing field. In Corporate Finance, we group these into four "Vital Sign" categories.

1. Liquidity Ratios (Can they pay their bills tomorrow?)

These measure a company's ability to meet its short-term obligations.

• Current Ratio: Measures if current assets can cover current liabilities.

Current Ratio = Current Assets \ Current Liabilities

Target: Usually 1.5 to 2.0. Anything below 1.0 is a "Red Flag" (danger of running out of cash).

2. Profitability Ratios (How efficient are they at making money?)

These tell you how much of every rupee in sales actually turns into profit.

• Net Profit Margin: The "Bottom Line" efficiency.

Net Profit Margin = (Net Income\ Revenue) x 100

• Return on Equity (ROE): How much profit the company generates with the money shareholders have invested.

ROE = (Net Income \ Shareholders' Equity) x 100

3. Leverage Ratios (How much "Borrowed Power" are they using?)

As we saw in the Leverage chapter, debt is a tool, but too much is a trap.

• Debt-to-Equity (D/E) Ratio:

D/E Ratio} = Total Liabilities \ Total Shareholders' Equity

• Interest Coverage Ratio: Can the company's earnings cover its interest payments?

Interest Coverage = EBIT \ Interest Expense

Example Calculation: If a firm earns ₹50 Lakhs (EBIT) and owes ₹10 Lakhs in interest, its coverage is 5x. If this drops to 1.5x, the company is in the "Danger Zone."

4. Valuation Ratios (Is the stock "Cheap" or "Expensive"?)

These help investors decide if the current market price makes sense.

• Price-to-Earnings (P/E) Ratio: How much investors are willing to pay for ₹1 of profit.

P/E Ratio = Market Price per Share \ Earnings Per Share (EPS)

5. Master Example Calculation: The "Fitness Test"

Let's analyze "Z-Tech Electronics" for 2026.

• Revenue: ₹500 Cr | Net Income: ₹50 Cr
• Total Assets: ₹300 Cr | Total Equity: ₹200 Cr
• Current Assets: ₹100 Cr | Current Liabilities: ₹50 Cr

Step 1: Liquidity Check

Current Ratio = 100 / 50 = 2.0x (Healthy)

Step 2: Profitability Check

Net Margin = (50 / 500) x 100 = 10%

ROE = (50 / 200) x 100 = 25% (Excellent)

Step 3: Efficiency Check (Asset Turnover)

How well do they use assets to make sales?

Asset Turnover = Net Sales / Average Total Assets

Asset Turnover = 500 / 300 = 1.67x

6. The "Industry Context" Rule

Never judge a ratio in a vacuum.

• A 10% Profit Margin is amazing for a Supermarket (high volume, low margin) but terrible for a Software company (low volume, high margin).
• A High D/E Ratio is normal for a Bank but scary for a Tech Startup.

Summary

• Ratios turn raw data into actionable insights.
• Liquidity is about survival; Profitability is about success.
• ROE is the ultimate metric for shareholders.
• Always compare a company's ratios to its past performance and its industry peers.
