Financial Ratio Analysis: From Basics to Business Mastery

This Part introduces profitability ratios, which evaluate a company’s ability to generate profits relative to sales, assets, and equity.

It explains how these ratios help analysts, investors, and managers assess whether the business is creating real value for shareholders.

It highlights two main categories:

• Return Ratios → Show how effectively the company generates returns (ROE, ROA, ROCE).

• Margin Ratios → Show how efficiently sales are converted into profits (Gross Margin, Operating Margin, Net Profit Margin).

After completing this section, students will be able to:

• Calculate and interpret key profitability ratios.

• Analyse how well a business converts resources into profits.

• Compare companies across industries to assess efficiency and profitability.

This Part explains how margin ratios track profitability at different stages of the income statement.

• Gross Margin Ratio → Shows how much profit remains after covering the cost of goods sold. It varies significantly across industries (e.g., higher for services, lower for manufacturing).

• Operating Profit Margin (EBIT) → Indicates how efficiently core operations generate profit before interest and taxes, highlighting operational efficiency.

• Net Profit Margin → The bottom line—how much actual profit remains after all expenses, taxes, and interest are deducted.

After completing this section, students will be able to:

• Calculate gross, operating, and net profit margins.

• Compare companies across industries with the right context.

• Interpret margins to assess overall profitability and efficiency.

This Part introduces leverage ratios, which measure a company's reliance on debt versus equity to finance its assets.

These ratios reflect solvency, financial stability, and risk.

• Debt-to-Equity Ratio → Shows the balance between borrowed funds and shareholder funds. A higher ratio means greater reliance on debt.

• Equity Ratio → Indicates the proportion of assets financed by equity, showing the strength of shareholders’ claims.

• Debt Ratio (Debt-to-Assets) → Measures the share of total assets funded by debt. A higher ratio signals higher financial risk.

After completing this section, students will be able to:

• Calculate leverage ratios using real financial data.

• Assess a company’s risk profile and solvency.

• Compare debt-equity structures across companies and industries.

This slide introduces turnover ratios, which show how efficiently a business completes financial cycles (collecting receivables, selling inventory, using assets).

• Accounts Receivable Turnover & Days → Show how quickly a business collects cash from credit sales, reflecting credit policy effectiveness.

• Asset Turnover Ratio → Indicates how efficiently assets generate sales, measuring resource utilisation.

• Inventory Turnover & Days → Reveal how quickly stock is sold and replaced, showing inventory management efficiency.

After completing this section, students will be able to:

• Calculate receivables, assets, and inventory turnover ratios.

• Interpret days outstanding for receivables and inventory.

• Use turnover insights to evaluate efficiency across different industries.

This Part introduces liquidity ratios, which measure a company’s ability to meet its short-term obligations without financial stress. These ratios are vital for creditors, investors, and managers to assess risk and stability.

• Current Ratio → Broad measure of liquidity, comparing all current assets to liabilities. (>1 = financial health, but too high may show idle funds).

• Quick Ratio → A stricter test, excluding inventory, shows whether a business can pay debts using only near-cash assets. (>1 = strong liquidity).

• Cash Ratio → The strictest measure, relying only on cash and equivalents. Too high may mean idle cash, too low may indicate risk.

• Defensive Interval Ratio (DIR) → Expressed in days, showing how long a firm can survive using only liquid assets without new income.

After completing this section, students will be able to:

• Calculate and interpret all major liquidity ratios.

• Understand how liquidity ratios differ in strictness.

• Apply liquidity insights to creditworthiness and risk evaluation.

This Part introduces earnings and cash flow ratios, which measure how effectively a company’s profits and operating cash flows cover debt obligations and support growth.

• Times Interest Earned (TIE) Ratio → Shows how comfortably earnings can cover interest payments. Higher ratios mean stronger creditworthiness.

• Cash-Basis TIE Ratio → A stricter version using actual cash flow, ensuring a company can truly pay its debt from operations.

• CAPEX to Operating Cash Ratio → Reveals how much cash flow is reinvested in growth projects, signalling financial strategy and risk.

• Operating Cash Flow Ratio → Tests if operational cash is enough to cover short-term liabilities.

• 
  

After completing this section, students will be able to:

• Calculate both accrual- and cash-based interest coverage ratios.

• Evaluate liquidity using cash flow, not just accounting profit.

• Interpret how companies balance debt payments with reinvestment.

• Identify financial risks from insufficient operating cash flow.

This Part introduces multiple valuation ratios, tools used by analysts and investors to determine if a company is under- or over-valued relative to its peers.

• Price Ratios (P/E) → Show how much investors are willing to pay per dollar of earnings. High ratios may indicate growth potential or overvaluation, while low ratios may suggest undervaluation or increased risk.

• EV/EBITDA → Neutralises differences in capital structure; widely used in M&A and cross-company comparisons.

• EV/EBIT → Similar to EV/EBITDA but considers depreciation and amortisation, reflecting businesses with heavy fixed assets.

• EV/Revenue → Useful for early-stage or loss-making companies, showing how markets value each unit of revenue.

After completing this section, students will be able to:

• Calculate and interpret key market valuation ratios.

• Understand how investors and analysts assess company value.

• Compare companies across industries, adjusting for growth, debt, and risk.
