The purpose and benefits of ratio analysis

Ratio analysis examines financial statements to evaluate a business's performance. It involves calculating ratios from figures in the income statement and balance sheet, producing numerical results that highlight key aspects of financial health.

Key benefits of ratio analysis

• Tracking performance over time - Ratios allow businesses to monitor financial trends, such as improvements or declines in profitability or liquidity, across different periods.
• Identifying strengths and weaknesses - By analysing ratios, businesses can pinpoint areas of strong performance, like efficient cost control, or issues, such as high debt levels.
• Accounting for influencing factors - Effective ratio analysis considers external variables, including inflation rates, differences in accounting methods, the nature of business operations, and broader market conditions, to ensure accurate interpretations.

How managers and investors use ratio analysis

Ratio analysis provides valuable insights for internal decision-making and external investment choices. It helps stakeholders assess risk and opportunities based on financial data.

Use by managers

Managers apply ratios to guide operational decisions and improve financial management.

Examples of how managers use ratios:

• Improving cash flow - If the payables days ratio indicates short payment terms with suppliers, managers might negotiate extended credit periods to retain more cash within the business.
• Strategic planning - Ratios help in setting targets, allocating resources, and addressing inefficiencies revealed by the analysis.

Use by investors

Potential investors rely on ratios to evaluate the viability and risk of investing in a business.

Examples of how investors use ratios:

• Assessing risk levels - High gearing ratios, which show significant debt relative to equity, might deter investors who view the business as overly risky due to potential difficulties in repaying loans.
• Informed investment choices - Investors use ratios to compare potential returns against risks, deciding whether to provide funding based on the business's financial stability.

The importance of comparing ratios between businesses

Comparing ratios across different businesses offers a more reliable way to assess performance than relying on absolute figures alone. This approach accounts for variations in business size and scale.

Benefits of inter-business comparisons

• Standardised evaluation - Ratios provide a common metric, allowing meaningful comparisons even between businesses of different sizes, where raw profit figures might be misleading.
• Benchmarking performance - Businesses can measure their ratios against industry averages or competitors to identify relative strengths, such as superior efficiency, or areas needing improvement.
• Contextual insights - Comparisons highlight how external factors, like market competition, affect ratios, making it easier to understand if poor results are due to internal issues or industry-wide challenges.

Limitations of ratio analysis

While ratio analysis is a useful tool, it has several drawbacks that limit its effectiveness. It should not be used in isolation, as it fails to capture the full picture of a business's situation.

Key limitations of ratio analysis

• Exclusion of non-numerical factors - Ratios focus solely on financial data and ignore qualitative elements, such as the expertise of employees or internal strengths like innovative processes, which do not appear in accounts.
• Ignoring external influences - Calculations do not reflect broader conditions, including economic downturns, competitive pressures, or market changes, where declining ratios might be typical rather than a sign of failure.
• Historical focus only - Ratios are based on past and present data, so they cannot predict future developments, such as technological innovations or shifts in interest rates, and may show poor results for businesses in early investment stages before benefits emerge.
• Need for additional data - Firm conclusions cannot be drawn from ratios alone; they must be combined with other information, including market trends, competitor actions, and qualitative assessments, as past performance does not reliably forecast future outcomes due to changing conditions.
