Ratios, Analysis, and Common-Size Statements

Navigate financial ratios, common-size statements, trends, margins, returns, liquidity, leverage, coverage, and efficiency analysis.

Financial-statement analysis turns reported amounts into comparisons across periods, companies, and operating drivers. Ratios relate selected quantities; common-size statements scale lines by a shared base; and trend analysis tracks amounts, percentages, and relationships over time.

These tools organize evidence. They do not replace the filed statements, notes, cash-flow analysis, or business context.

BranchMain questions
Common-Size, Trend, and Statement AnalysisHow have statement amounts and composition changed, and which baseline makes the comparison meaningful?
Liquidity and Cash-Flow Coverage RatiosCan near-term resources and defined cash-flow measures support obligations and required payments?
Leverage, Equity, and Capital Structure RatiosHow are assets and operations financed, and how large are creditor claims relative to equity or assets?
Profitability, Margin, and Return RatiosHow effectively do revenue, assets, equity, inventory, or capital produce defined profit?
Turnover and Efficiency RatiosHow quickly do inventory, receivables, fixed assets, working capital, or capital support activity?

Start with Accounting Ratio when the correct formula or ratio family is unclear.

A Practical Analysis Sequence

  1. Define the decision question before selecting a ratio.
  2. Reconcile each input to the statement and notes.
  3. Align periods, currency, entity scope, and accounting definitions.
  4. Use average balances where a period measure is compared with a point-in-time resource.
  5. Compare absolute amounts before relying on percentages or multiples.
  6. Add historical, budget, and peer baselines where each is relevant.
  7. Connect profitability with cash conversion, leverage, liquidity, and reinvestment.
  8. Investigate causes rather than extrapolating the observed relationship.

Common Interpretation Risks

  • Higher return on equity can result from greater leverage or a smaller equity base rather than stronger operations.
  • Higher liquidity ratios can reflect slow inventory or overdue receivables rather than available cash.
  • Better margins can result from classification changes, mix shifts, or gross-versus-net revenue presentation.
  • Strong turnover can reflect efficient use of assets or old assets with low carrying amounts.
  • Covenant and regulatory ratios can use definitions that differ from ordinary analytical measures.

Choose a subsection first. Deeper term pages live inside each subsection, which keeps large topic hubs readable.

Common-Size & Trend

Compare financial statements using common-size percentages, vertical and trend analysis, accounting ratios, and clearly defined analytical baselines.

Leverage Ratios

Leverage ratios compare assets, liabilities, debt, and equity to assess funding structure, loss absorption, and financial risk.

Liquidity & Coverage

Liquidity and coverage ratios comparing current resources, operating cash flow, capital spending, interest, and near-term obligations.

Profitability Ratios

Financial ratios for operating margin, EBITDA-to-sales, GMROI, ROA, ROE, ROTA, and return on revenue.

Turnover Ratios

Turnover ratios compare business activity with assets, inventory, fixed assets, working capital, or capital employed.
