Ratio Analysis: Types, Uses, and Calculations

TAKEAWAYS:

• Ratios compare financial numbers to reveal a company’s strengths and weaknesses.
• Liquidity ratios show if a company can pay short-term debts; profitability ratios measure earnings; solvency ratios assess long-term stability.
• NEB exams test calculations (e.g., current ratio, debt-to-equity) and interpretations (e.g., "Is a 2:1 current ratio good?").
• Always compare ratios to industry benchmarks or past years for meaningful insights.
• Mistakes in ratio formulas (e.g., mixing up assets/liabilities) lose marks—double-check!
• Memorize 5 key ratios (current, quick, gross profit, net profit, debt-to-equity) and their formulas.

What Are Financial Ratios?

Financial ratios are mathematical tools that compare two or more financial figures from a company’s statements (Balance Sheet, Income Statement) to assess its performance. Think of them as a financial health check—like a doctor checking your pulse and blood pressure.

Why use ratios?

• Simplify complex data: Turn numbers into easy-to-understand insights.
• Compare over time: Track improvements or declines (e.g., "Our profit margin dropped from 20% to 15%").
• Benchmark against competitors: See if your company is doing better or worse than peers.
• Help investors/lenders decide: Banks use ratios to approve loans; investors use them to buy/sell shares.

Types of Ratios (The 3 Big Categories)

Ratios are grouped into three main types, each answering a different question about the business. Use this table to organize your notes:

1. Liquidity Ratios: "Can We Pay the Bills?"

Definition: These ratios measure a company’s ability to pay short-term debts (due within a year) using its current assets (cash, inventory, receivables).

A. Current Ratio

Formula: $$\text{Current Ratio}=\frac{\text{Current Assets}}{\text{Current Liabilities}}$$ What it tells you:

• A ratio of 1.5:1 or higher means the company can pay its short-term debts comfortably.
• <1:1 means trouble—more liabilities than assets to cover them.

Example: From the Balance Sheet of ABC Ltd.:

• Current Assets = Rs. 500,000 (Cash Rs. 100,000 + Inventory Rs. 200,000 + Receivables Rs. 200,000)
• Current Liabilities = Rs. 300,000 (Payables + Short-term Loans)

Calculation: $$\text{Current Ratio}=\frac{500,000}{300,000}=1.67:1$$ Interpretation: ABC Ltd. can pay its short-term debts 1.67 times over. This is good (benchmark: 1.5:1).

B. Quick Ratio (Acid-Test Ratio)

Why? Some assets (like inventory) aren’t easily converted to cash. The quick ratio ignores inventory to give a stricter test.

Formula: $$\text{Quick Ratio}=\frac{\text{Current Assets}-\text{Inventory}}{\text{Current Liabilities}}$$ Example: Using ABC Ltd.’s data: $$\text{Quick Ratio}=\frac{500,000-200,000}{300,000}=\frac{300,000}{300,000}=1:1$$ Interpretation: ABC Ltd. can pay its debts even if inventory doesn’t sell quickly. Still safe, but less cushion than the current ratio.

2. Profitability Ratios: "Are We Making Money?"

These ratios show how well a company generates profit from its sales and investments.

A. Gross Profit Margin

Formula: $$\text{Gross Profit Margin (\%)}=\left(\frac{\text{Gross Profit}}{\text{Net Sales}}\right)\times 100$$ What it tells you:

• Measures core profitability before expenses like rent or salaries.
• Higher % = better pricing/purchasing power.

Example: From the Income Statement of XYZ Ltd.:

• Net Sales = Rs. 1,000,000
• Cost of Goods Sold (COGS) = Rs. 600,000
• Gross Profit = Rs. 400,000

Calculation: $$\text{Gross Profit Margin}=\left(\frac{400,000}{1,000,000}\right)\times 100=40\%$$ Interpretation: For every Rs. 100 of sales, XYZ earns Rs. 40 in gross profit. Good if the industry average is 30%.

B. Net Profit Margin

Formula: $$\text{Net Profit Margin (\%)}=\left(\frac{\text{Net Profit}}{\text{Net Sales}}\right)\times 100$$ What it tells you:

• Shows bottom-line efficiency after all expenses (taxes, interest, salaries).
• A declining margin may mean rising costs.

Example: Using XYZ Ltd.’s data:

• Net Profit = Rs. 100,000 (after all expenses) $$\text{Net Profit Margin}=\left(\frac{100,000}{1,000,000}\right)\times 100=10\%$$ Interpretation: XYZ keeps 10% of sales as pure profit. Compare to competitors—if they average 15%, XYZ needs to cut costs or raise prices.

3. Solvency Ratios: "Can We Survive Long-Term?"

These ratios assess a company’s long-term financial health, especially its debt levels.

A. Debt-to-Equity Ratio

Formula: $$\text{Debt-to-Equity Ratio}=\frac{\text{Total Debt}}{\text{Shareholders’ Equity}}$$ What it tells you:

• High ratio (>2) = risky (too much debt).
• Low ratio (<1) = conservative (relying on equity).

Example: From ABC Ltd.’s Balance Sheet:

• Total Debt = Rs. 800,000 (Long-term loans + Current liabilities)
• Shareholders’ Equity = Rs. 1,200,000

Calculation: $$\text{Debt-to-Equity}=\frac{800,000}{1,200,000}=0.67:1$$ Interpretation: ABC uses Rs. 0.67 of debt for every Rs. 1 of equity. This is safe (benchmark: <1).

B. Interest Coverage Ratio

Formula: $$\text{Interest Coverage}=\frac{\text{EBIT}}{\text{Interest Expense}}$$ What it tells you:

• EBIT = Earnings Before Interest and Taxes.
• Shows how easily a company can pay interest on its debt.

Example: From XYZ Ltd.’s Income Statement:

• EBIT = Rs. 200,000
• Interest Expense = Rs. 50,000

Calculation: $$\text{Interest Coverage}=\frac{200,000}{50,000}=4$$ Interpretation: XYZ can pay its interest 4 times over. Strong (benchmark: >1.5).

Common Mistakes to Avoid

1. Mixing up assets/liabilities:

   • ❌ Current Ratio = Liabilities / Assets (wrong!)
   • ✅ Current Ratio = Assets / Liabilities (correct!)

2. Ignoring industry benchmarks:

   • A 20% profit margin may be average for retail but weak for tech.

3. Using wrong figures:

   • For gross profit margin, use sales revenue, not net income.

4. Forgetting units:

   • Ratios are unitless (e.g., 1.5:1, not "1.5 Rs.").

NEB-Style Questions and Solutions

Question 1: Calculation (5 marks)

From the following data of Sunrise Ltd., calculate:

1. Current Ratio
2. Gross Profit Margin
3. Debt-to-Equity Ratio

Solution:

1. Current Ratio: $$\frac{800,000}{500,000}=1.6:1$$
2. Gross Profit Margin:
   • Gross Profit = Sales – COGS = 1,500,000 – 900,000 = 600,000 $$\left(\frac{600,000}{1,500,000}\right)\times 100=40\%$$
3. Debt-to-Equity Ratio: $$\frac{1,200,000}{2,000,000}=0.6:1$$

Question 2: Interpretation (3 marks)

"The current ratio of a company is 0.8:1, and its quick ratio is 0.5:1. Comment on its liquidity position."

Solution:

• Current Ratio (0.8:1): The company has only Rs. 0.8 of current assets for every Rs. 1 of current liabilities. This is dangerous—it may struggle to pay short-term debts.
• Quick Ratio (0.5:1): Even worse—without inventory, it can cover only 50% of liabilities. Immediate action needed (e.g., sell inventory, borrow short-term).

Question 3: Comparison (4 marks)

"Distinguish between gross profit margin and net profit margin with an example."

Solution:

Exam Tip: How to Score Full Marks

1. Show all steps:

   • NEB expects formulas + substitutions + final answer. Never skip steps.

2. Label clearly:

   • Write "1. Current Ratio" before calculations.

3. Interpret ratios:

   • Always add 1 sentence explaining what the number means (e.g., "This shows the company is liquid").

4. Compare with benchmarks:

   • If asked, say "The industry average is X; our ratio is Y, so we are [better/worse]."

5. Avoid vague answers:

   • ❌ "The ratio is good."
   • ✅ "The current ratio of 1.8:1 is better than the industry average of 1.5, indicating strong short-term liquidity."

6. Practice with real data:

   • Use past NEB questions or company annual reports (e.g., NMB Bank, Himalayan Bank) to calculate ratios.

Final Challenge: Try This!

Given:

• Current Assets = Rs. 1,200,000
• Inventory = Rs. 300,000
• Current Liabilities = Rs. 800,000
• Net Sales = Rs. 2,000,000
• COGS = Rs. 1,200,000
• Total Debt = Rs. 1,500,000
• Equity = Rs. 2,500,000

Calculate:

1. Quick Ratio
2. Gross Profit Margin
3. Debt-to-Equity Ratio

Answers:

1. Quick Ratio = (1,200,000 – 300,000) / 800,000 = 1.125:1
2. Gross Profit Margin = (800,000 / 2,000,000) × 100 = 40%
3. Debt-to-Equity = 1,500,000 / 2,500,000 = 0.6:1
