Accounting Ratios and What They Mean

In the previous chapter, "Tools for Financial Statement Analysis", we looked at how to compare financial data over time using comparative and common-size statements. But looking at raw numbers on a balance sheet or an income statement often hides the real story.

Imagine two companies, Company A and Company B. Company A reports a net profit of ₹10 Lakhs this year. Company B reports a net profit of ₹1 Crore. Which company is doing better?

Your instinct might be to say Company B. But what if I told you that Company A started with an investment of just ₹20 Lakhs, while Company B required an investment of ₹50 Crores? Suddenly, Company A looks like a brilliant business, while Company B looks like a terrible place to park your money.

Absolute numbers lie by omission. They tell you what happened, but they don't give you the context to understand how well it happened. To get that context, we have to compare one number against another. We have to use ratios.

What is Ratio Analysis?

A ratio is simply a mathematical relationship between two numbers. It can be expressed as a pure proportion (like 2:1), a percentage (like 20%), or a multiple (like 5 times).

For investors and managers, ratio analysis is the ultimate diagnostic tool. Think of a doctor looking at your blood test results. The doctor doesn't just look at your raw cholesterol number; they look at the ratio of "good" cholesterol to "bad" cholesterol to determine your heart health.

Similarly, financial ratios help stakeholders answer critical questions:

• Managers use ratios to spot inefficiencies. Are we holding too much unsold stock? Are our profit margins shrinking compared to last year?
• Banks and Lenders use ratios to check safety. If we give this company a loan, do they generate enough cash to pay the interest every month?
• Investors use ratios to find value. Is this company generating a good enough return on the money I invested?

In this chapter, we are going to master three major categories of ratios: Liquidity (short-term health), Solvency (long-term stability), and Profitability (earning power).

1. Liquidity Ratios: Can We Pay Our Bills Today?

Liquidity refers to a business's ability to convert its assets into cash quickly to pay off its short-term obligations. If a company cannot pay its suppliers, its electricity bill, or its employees' wages this month, it doesn't matter how profitable its ten-year plan is—it will go bankrupt today.

To check this short-term health, we use two primary liquidity ratios.

The Current Ratio

The Current Ratio measures whether a company has enough short-term assets to cover its short-term debts.

The Formula:

Current Ratio = Current Assets / Current Liabilities

To calculate this, you need to know what goes into the numerator and the denominator:

• Current Assets: Assets that are expected to be converted into cash within one year. This includes Cash in hand, Cash at bank, Sundry Debtors (money owed to you by customers), Inventory (unsold stock), and Prepaid Expenses (rent or insurance paid in advance).
• Current Liabilities: Debts that must be paid within one year. This includes Sundry Creditors (money you owe to suppliers), Short-term bank loans, Bank Overdrafts, and Outstanding Expenses (like unpaid wages).

How to Interpret It: The standard rule of thumb for a healthy Current Ratio is 2:1. This means for every ₹1 of short-term debt, the company has ₹2 of short-term assets.

Why do we need double the assets? Because not all current assets are perfectly reliable. What if half your debtors delay their payments? What if a portion of your inventory gets damaged or goes out of fashion and cannot be sold? Having a 2:1 ratio provides a comfortable safety cushion.

If the ratio is less than 1 (e.g., 0.8:1), the company is in the danger zone. It owes more money in the short term than it has coming in. However, a ratio that is too high (like 5:1) isn't great either. It means the company is hoarding cash or letting inventory pile up instead of investing that money to grow the business.

The Quick Ratio (The Acid Test)

The Current Ratio is good, but it has a flaw: it assumes you can sell your inventory quickly. In reality, if a business faces a sudden cash crunch, selling a warehouse full of half-finished goods or raw materials is very difficult.

The Quick Ratio (often called the Acid Test Ratio) is a stricter, more conservative measure of liquidity. It asks: "If our sales stopped completely tomorrow, could we still pay our immediate bills?"

The Formula:

Quick Ratio = Quick Assets / Current Liabilities

How to find Quick Assets: Quick Assets are simply Current Assets minus the things that take time to convert to cash.

Quick Assets = Current Assets - Inventory - Prepaid Expenses

We subtract Inventory because it takes time to sell. We subtract Prepaid Expenses because you cannot ask your landlord to refund your prepaid rent just because you need cash; that money is gone and cannot be used to pay other bills.

How to Interpret It: The standard rule of thumb for a healthy Quick Ratio is 1:1. This means for every ₹1 of short-term debt, the company has exactly ₹1 of highly liquid assets (cash, bank balance, and reliable debtors) ready to go. A ratio of 1:1 means the business can survive a sudden shock without needing to fire-sale its inventory.

2. Solvency Ratios: Will We Survive the Long Run?

While liquidity looks at the next 12 months, solvency looks at the next 5 to 10 years. Solvency ratios measure a company's ability to meet its long-term debts and interest payments.

A company that relies too heavily on borrowed money (debt) is taking a massive risk. When times are good, debt helps a business grow fast. But when the economy slows down, the bank still demands its fixed interest payments. If the company can't pay, it faces liquidation.

The Debt-to-Equity Ratio

This is the most famous solvency ratio. It compares the money borrowed from outsiders (Debt) to the money invested by the owners (Equity). It tells us who really owns the business—the shareholders or the banks.

The Formula:

Debt-to-Equity Ratio = Long-Term Debt / Shareholder's Equity

• Long-Term Debt: Borrowings that are due after more than one year. This includes Debentures, Long-term Bank Loans, and Bonds. (Do not include current liabilities here).
• Shareholder's Equity (or Shareholder's Funds): The owners' money. This includes Equity Share Capital, Preference Share Capital, and all Reserves and Surplus (accumulated profits).

How to Interpret It: A generally acceptable Debt-to-Equity ratio is 2:1. This means a company can safely have twice as much long-term debt as it has equity. If a company has ₹10 Lakhs in equity, it is generally safe to carry up to ₹20 Lakhs in long-term debt.

If the ratio is much higher (say, 4:1 or 5:1), the company is "highly leveraged." This is a massive red flag for investors. It means the business is drowning in debt, and a huge portion of its operating profit will be eaten up by interest payments. If the ratio is very low (say, 0.5:1), the company is financially very secure, though it might be missing out on opportunities to grow using cheap borrowed funds.

The Interest Coverage Ratio

Having debt isn't inherently bad, provided the company earns enough profit to easily pay the interest on that debt. The Interest Coverage Ratio measures exactly this safety margin. It tells us how many times over the company can pay its interest bills using its current earnings.

The Formula:

Interest Coverage Ratio = EBIT / Interest on Long-Term Debt

How to Interpret It: Unlike the previous ratios, this one is expressed in "times" rather than a proportion. If a company has an EBIT of ₹5,00,000 and its annual interest bill is ₹1,00,000, its Interest Coverage Ratio is 5 times.

A higher number is always better. A ratio of 6 or 7 times means the company is very comfortable; even if profits drop by 50% next year, they can still easily pay the bank. A ratio of 1.5 times or lower is dangerous—it means the company is barely scraping by, and any slight dip in sales could lead to a default on their loans.

3. Profitability Ratios: Are We Actually Making Money?

A business can be liquid (lots of cash) and solvent (low debt), but if it isn't profitable, it has no future. Profitability ratios measure how efficiently a company generates profit relative to its sales or its invested capital.

These ratios are almost always expressed as percentages.

The Gross Profit Margin

This ratio looks at the core profitability of the goods or services being sold, before any office, administrative, or selling expenses are deducted. It tells you the markup the company is achieving on its products.

The Formula:

Gross Profit Margin = (Gross Profit / Revenue from Operations) × 100

• Gross Profit: Revenue from Operations minus the Cost of Goods Sold (COGS). It only accounts for direct costs (like raw materials and factory wages).
• Revenue from Operations: This is the modern accounting term for Net Sales (Total Sales minus Sales Returns).

How to Interpret It: If a company sells shoes for ₹1,000 and the direct cost to make those shoes is ₹600, the Gross Profit is ₹400. The Gross Profit Margin is 40%. A higher margin is better. It means the company has a strong brand and can charge a premium, or it has highly efficient manufacturing. If the Gross Profit Margin is falling over time, it means raw material costs are rising, or the company is being forced to offer heavy discounts to survive.

The Net Profit Margin

While Gross Profit looks at the factory floor, Net Profit looks at the entire business. It deducts everything—office salaries, rent, marketing, interest, and taxes. This ratio tells you how much of every Rupee earned actually ends up in the owners' pockets.

The Formula:

Net Profit Margin = (Net Profit After Tax / Revenue from Operations) × 100

How to Interpret It: If a company has a Net Profit Margin of 15%, it means that for every ₹100 of sales, the company keeps ₹15 as pure profit. Investors watch this ratio like a hawk. A company might have massive sales growth, but if its Net Profit Margin is shrinking, it means expenses are spiraling out of control. Comparing the Gross Profit Margin and the Net Profit Margin is also revealing: if a company has a high Gross margin (50%) but a tiny Net margin (2%), it means their manufacturing is great, but they are wasting all their money on administrative overheads or massive interest payments.

Return on Investment (ROI) / Return on Capital Employed (ROCE)

This is arguably the single most important ratio in financial management. It doesn't just look at profit compared to sales; it looks at profit compared to the total money invested in the business. It answers the ultimate question: "Is this business worth running?"

The Formula:

ROI (or ROCE) = (EBIT / Capital Employed) × 100

• EBIT: Earnings Before Interest and Taxes (Operating Profit).
• Capital Employed: The total long-term funds invested in the business. You can calculate this in two ways (both give the same answer):

1. 1Liabilities approach: Shareholder's Equity + Long-Term Debt
2. 2Assets approach: Total Assets - Current Liabilities

How to Interpret It: If a company has a Capital Employed of ₹10,00,000 and generates an EBIT of ₹2,00,000, its ROI is 20%. Why is this so crucial? Because if the ROI is 20%, but the bank is charging 10% interest on loans, the business is creating wealth. It is borrowing at 10% and earning 20%. However, if the ROI drops to 8%, the business is destroying wealth. It is paying the bank 10% but only earning 8% on that money. An investor looking at an 8% ROI might decide to shut the business down and just put their money in a fixed deposit instead!

Master Worked Example

To truly understand these ratios, you must see them work together. Let’s look at the financial data for a fictional company, Himalayan Apples & Orchards Ltd., for the year ending March 31.

The Raw Data:

• Revenue from Operations (Net Sales): ₹20,00,000
• Gross Profit: ₹8,00,000
• Net Profit (After Tax): ₹3,00,000
• EBIT (Operating Profit): ₹5,00,000
• Interest on Long-Term Debt: ₹1,00,000
• Current Assets: ₹6,00,000 (This includes Inventory of ₹1,50,000 and Prepaid Insurance of ₹50,000)
• Current Liabilities: ₹3,00,000
• Long-Term Debt: ₹8,00,000
• Shareholder's Equity: ₹12,00,000

Let's calculate all seven ratios and interpret the health of this company.

1. Current Ratio

• Formula: Current Assets / Current Liabilities
• Calculation: ₹6,00,000 / ₹3,00,000 = 2:1
• Interpretation: Perfect. The company has exactly double the short-term assets to cover its short-term liabilities.

2. Quick Ratio

• Formula: Quick Assets / Current Liabilities
• Quick Assets = ₹6,00,000 - ₹1,50,000 (Inventory) - ₹50,000 (Prepaid) = ₹4,00,000
• Calculation: ₹4,00,000 / ₹3,00,000 = 1.33:1
• Interpretation: Excellent. Even if they sell zero apples tomorrow, they have ₹1.33 in highly liquid cash/debtors for every ₹1 of immediate debt. They are well above the 1:1 standard.

3. Debt-to-Equity Ratio

• Formula: Long-Term Debt / Shareholder's Equity
• Calculation: ₹8,00,000 / ₹12,00,000 = 0.67:1
• Interpretation: Very safe. The owners have invested far more money (₹12L) than the banks have lent (₹8L). They are well below the risky 2:1 threshold.

4. Interest Coverage Ratio

• Formula: EBIT / Interest on Long-Term Debt
• Calculation: ₹5,00,000 / ₹1,00,000 = 5 times
• Interpretation: Strong. The company earns 5 times more operating profit than it needs to pay its interest bill. The bank will happily lend them more money.

5. Gross Profit Margin

• Formula: (Gross Profit / Revenue from Operations) × 100
• Calculation: (₹8,00,000 / ₹20,00,000) × 100 = 40%
• Interpretation: Healthy. For every ₹100 of apples sold, the direct cost is ₹60, leaving ₹40 to cover office expenses and profit.

6. Net Profit Margin

• Formula: (Net Profit / Revenue from Operations) × 100
• Calculation: (₹3,00,000 / ₹20,00,000) × 100 = 15%
• Interpretation: Good. After paying all salaries, rent, interest, and taxes, the owners take home ₹15 for every ₹100 in sales.

7. Return on Investment (ROI / ROCE)

• Formula: (EBIT / Capital Employed) × 100
• Capital Employed = Equity (₹12,00,000) + Long-Term Debt (₹8,00,000) = ₹20,00,000
• Calculation: (₹5,00,000 / ₹20,00,000) × 100 = 25%
• Interpretation: Outstanding. The business generates a 25% return on the total capital invested in it. This is a highly efficient, wealth-creating machine.

Final Verdict on Himalayan Apples & Orchards Ltd.: By looking at the raw numbers alone, we just saw a bunch of zeroes. But by running the ratios, we can confidently say this is a highly liquid, safely solvent, and deeply profitable business.
