Limitations of Ratio Analysis in ACCA FR

Updated 11 October 2026 · Fact-checked

Ratio analysis turns financial statements into comparable measures, but it has limits. Ratios use historic data, can be distorted at the year end, depend on accounting policies and definitions, and are hard to compare across companies. To answer, name the limitation and tie it to the scenario.

Understand Limitations of Ratio Analysis

A ratio compares one figure with another. It helps you spot trends, compare entities and judge performance. But a ratio is only as good as the numbers inside it. It is a starting point for questions, not an answer.

The first group of limitations is about the data. Financial statements show historic results. They tell you what happened, not what will happen. They also leave out non-financial matters such as staff quality, customer loyalty, order books and market conditions. Under historical cost, assets may be carried at old values, so return on capital employed can look high for an old business and low for a newly built one. Inflation makes trends over time misleading.

The second group is about timing. The statement of financial position shows one day only. A seasonal business may have very high inventory or low cash at its year end. A company can also time transactions near the year end, such as delaying payments or pushing sales in, to flatter liquidity and receivables ratios. This is called window dressing. Year-end figures may not represent the average through the year.

The third group is about comparability. There is no single set of ratio definitions. One firm may calculate gearing as debt ÷ equity and another as debt ÷ (debt + equity). Companies may use different accounting policies, such as cost or revaluation, or different depreciation methods and estimates. They may differ in size, business mix, financing, and year-end dates. Leases, group structure and one-off items add further noise. If you compare two firms, you must check that you are comparing like with like.

Finally, ratios are only part of the picture. A single ratio rarely says much. Judgement is needed on cause. You should also consider the sector average, but remember that an average may hide very different businesses.

How to solve Limitations of Ratio Analysis questions

Use this method whenever a question asks you to discuss the limitations of ratios or of comparing entities.

  1. 1Read the requirement. Note whether it asks about limitations in general, or about comparing two entities or two years.
  2. 2Scan the scenario for clues: different year ends, different policies, seasonal trade, big year-end transactions, revalued assets, one-off items, different sizes or sectors.
  3. 3List three or four limitations that match those clues. Do not use a generic list that ignores the scenario.
  4. 4For each, state the limitation in one sentence, then explain the effect on the ratio, such as overstating or understating it.
  5. 5Use numbers from the question where possible, for example how a revaluation changes ROCE.
  6. 6Say what extra information you would want, such as budgets, industry averages, cash flow information, accounting policy notes or non-financial data.
  7. 7Finish with a short conclusion: ratios help but need context, so they should be used with other information.

Quickest way: Four-box check: data, timing, policies, context

When to use it: Use in written Section C parts or in an objective test question asking which statement is a limitation.

  1. Data: is it historic, at historical cost, excluding non-financial information?
  2. Timing: is it a single-day snapshot, seasonal, or open to window dressing?
  3. Policies: do definitions or accounting policies differ between entities or years?
  4. Context: do size, sector, group structure, year end or one-off items make comparison unfair?
  5. Pick the box that matches the scenario, make your point, and state the effect on the ratio.

Common mistakes in Limitations of Ratio Analysis

  • Writing a generic list of limitations with no link to the scenario.

    Students memorise a list and write it out to save time.

    Fix: Pick limitations triggered by clues in the question and refer to the specific figures or facts.

  • Naming a limitation but not explaining its effect on the ratio.

    Students think naming the point is enough for a mark.

    Fix: Always add: so the ratio is overstated or understated, or so the comparison is unreliable, and why.

  • Comparing two companies with different accounting policies as if they were identical.

    Students focus on calculating ratios and skip the notes.

    Fix: Check policy notes for depreciation, revaluation and inventory methods, and say the ratios may not be comparable.

  • Saying ratios are useless.

    Students overstate the limitations.

    Fix: Say ratios are useful for trends and questions but need to be used with other information and judgement.

  • Ignoring year-end timing effects such as seasonality or window dressing.

    Students treat the statement of financial position as typical of the whole year.

    Fix: Check the year end date and the business type, and note that the closing figures may not reflect average levels.

Worked examples

Example 1

Company A revalues its property upwards by ₹40,00,000 in the year. Before the revaluation its profit before interest and tax is ₹30,00,000 and capital employed is ₹1,00,00,000. Assume profit is unchanged and capital employed rises by the revaluation. Calculate ROCE before and after, and explain the limitation this shows.

Show the solution
  1. ROCE before = 30,00,000 ÷ 1,00,00,000 = 30%.
  2. Capital employed after = 1,00,00,000 + 40,00,000 = ₹1,40,00,000.
  3. ROCE after = 30,00,000 ÷ 1,40,00,000 = 21.4% (to one decimal place).
  4. Nothing changed in the trading performance, yet ROCE fell.
  5. The limitation is that ratios depend on accounting policies. A company that uses revaluation will show a lower ROCE than a similar company that holds assets at old cost, so comparison is unreliable.

Answer: ROCE falls from 30% to 21.4% purely because of the revaluation. This shows that differing accounting policies and use of historical cost versus current values reduce comparability.

Example 2

A retailer's year end is 31 January, just after its sales season. Its current assets are ₹60,00,000 (inventory ₹10,00,000) and current liabilities are ₹40,00,000. A rival has a 30 June year end. Calculate the current ratio and explain two limitations in comparing it with the rival.

Show the solution
  1. Current ratio = 60,00,000 ÷ 40,00,000 = 1.5.
  2. Limitation one: the year ends differ. At 31 January the retailer has sold off inventory and may hold high cash and receivables, while the rival's June position reflects a different point in its trading cycle. So the two snapshots are not comparable.
  3. Limitation two: a year-end figure may not represent the whole year. Seasonal trade or window dressing, such as delaying payments to suppliers, can make liquidity look better or worse than normal.
  4. Suggest using average or monthly figures, and checking policies and definitions, before drawing conclusions.

Answer: Current ratio is 1.5. Comparison with the rival is limited by different year ends and by year-end snapshots that may not reflect normal trading, so more information is needed.

Exam tips

  • In Section C, link every limitation to a clue in the scenario. Generic lists score poorly.
  • Always state the effect: does the limitation overstate or understate the ratio, or make comparison unreliable?
  • In objective tests, look for the option that matches a real limitation, such as historic data or differing policies. Avoid options that claim ratios are always misleading or always accurate.
  • If the question gives two companies, check year ends, policies, size and sector before commenting on performance.
  • Keep your points short. One limitation, one effect, one example from the question.

Limitations of Ratio Analysis: frequently asked questions

What are the main limitations of ratio analysis for ACCA FR?

The main ones are reliance on historic data, year-end snapshots that may be distorted, differing definitions and accounting policies, and poor comparability between entities. Ratios also ignore non-financial information. You should explain the effect of each one on the ratio.

How do I comment on limitations of ratios in the FR exam?

Pick limitations that match clues in the scenario, state each clearly, and explain how it affects the ratio or the comparison. Then say what extra information you would want. Finish with a short conclusion.

Why is it hard to compare ratios between companies?

Companies may use different accounting policies, year ends, financing structures and ratio definitions. They may also differ in size, sector and business mix. These differences mean the same ratio can mean different things.

What is window dressing?

Window dressing is arranging transactions near the year end to make the financial statements look better, for example delaying payments to improve cash or liquidity. It is a limitation because year-end ratios may not reflect normal conditions.
