Ratio Analysis in Performance Evaluation for ACCA Performance Management

Updated 11 October 2026 · Fact-checked

Ratio analysis turns financial statement figures into percentages and multiples so you can judge performance. You calculate profitability, liquidity, efficiency and risk ratios, then compare them with prior years, other divisions or benchmarks. The marks come from explaining why a ratio moved, not from the calculation alone.

Understand Ratio Analysis in Performance Evaluation

A single number such as profit of $400,000 tells you little. Is that good? It depends on sales, capital employed and what similar businesses earn. A ratio links two figures so the result can be compared across years, divisions or competitors.

Ratios fall into four groups. Profitability ratios show how well sales and capital turn into profit. Liquidity ratios show whether the business can pay its short-term debts. Efficiency ratios show how well assets, inventory, receivables and payables are managed. Risk ratios (gearing and interest cover) show how exposed the business is to its debt finance.

Ratios are linked. Return on capital employed (ROCE) equals operating profit margin multiplied by asset turnover. So a fall in ROCE must come from a lower margin, lower asset turnover or both. This link is a favourite exam route to a good explanation.

A ratio is only useful when compared. Use a trend over time, a budget, another division or an industry average. Then ask what caused the difference. Typical causes are selling price changes, cost control, product mix, asset age, credit policy or new borrowing.

In PM, ratios sit inside performance measurement. You may be asked to compare two divisions or companies, comment on a manager's results, or note the limits of ratios. Limits include different accounting policies, year-end timing, inflation, and the fact that ratios use historic financial data only.

Key rules to remember

Gross profit margin: Gross profit ÷ Revenue × 100%; Shows pricing and direct cost control.
Operating profit margin: Profit before interest and tax ÷ Revenue × 100%; Adds the effect of overheads to gross margin.
Net profit margin: Profit after tax ÷ Revenue × 100%; Use the definition given in the question if it states one.
ROCE: Profit before interest and tax ÷ Capital employed × 100%; Capital employed = total assets less current liabilities (equity plus long-term debt).
Asset turnover: Revenue ÷ Capital employed (times); Revenue generated per $1 of capital employed. ROCE = operating margin × asset turnover.
Current ratio: Current assets ÷ Current liabilities; Liquidity. Do not treat a fixed figure as always right; compare with the industry.
Quick ratio: (Current assets − Inventory) ÷ Current liabilities; Stricter liquidity test that excludes inventory.
Inventory days: Inventory ÷ Cost of sales × 365; Use cost of sales as the base.
Receivables days: Trade receivables ÷ Credit revenue × 365; Use total revenue if credit sales are not given.
Payables days: Trade payables ÷ Cost of sales × 365; Use credit purchases if given.
Gearing: Debt ÷ Equity × 100%, or Debt ÷ (Debt + Equity) × 100%; State which definition you use and keep it consistent.
Interest cover: Profit before interest and tax ÷ Finance costs (times); Low cover means profit is thin against interest.

How to solve Ratio Analysis in Performance Evaluation questions

Use this routine for any ratio question, whether it is a calculation, a comparison or a written assessment.

1Read the requirement. Note which ratios are asked for and whether you must comment, compare or recommend.
2Write down the formula for each ratio before you use it. Use the definition in the question if one is given.
3Pull the figures from the statements and calculate each ratio for every year or division. Show workings.
4Choose the comparison base: prior year, budget, another division or industry figure.
5For each ratio, state the movement or difference in one sentence with the numbers.
6Explain the likely cause. Link related ratios, such as margin and asset turnover to ROCE.
7Group your comments by theme: profitability, efficiency, liquidity, risk.
8Finish with a conclusion or recommendation, and mention limits such as missing data or different policies.

Quickest way: Margin-turnover-then-cause

When to use it: Use this in Section C when time is short and the question asks you to compare performance.

Calculate ROCE, operating margin and asset turnover first. They explain most of the difference.
Decide whether the gap comes from margin, turnover or both.
Calculate only the extra ratios that test your explanation, such as gross margin or inventory days.
Write one comment per ratio: figure, direction, likely reason.
End with a one-line verdict and one limitation.

Common mistakes in Ratio Analysis in Performance Evaluation

Listing ratios and calculating them but giving no explanation.
Calculations feel safe and earn quick marks, so students stop there.
Fix: For every ratio add what changed, why it probably changed and what it means for the business.
Using the wrong base, such as revenue instead of cost of sales for inventory days.
Students memorise the ×365 part but not the denominator.
Fix: Link each balance to its flow: inventory and payables to cost of sales, receivables to revenue.
Treating a high or low ratio as automatically good or bad.
Students learn rules of thumb such as a current ratio of 2.
Fix: Judge against the trend, the competitor and the industry. A low current ratio can suit a retailer that sells for cash.
Mixing definitions of gearing or capital employed between years or divisions.
Students rush and take figures from different lines.
Fix: State your definition once and apply it identically everywhere.
Ignoring the link between margin, turnover and ROCE.
Ratios are learned as separate formulas.
Fix: Always split ROCE into margin × turnover to locate the cause of a change.
Comparing divisions without noting different asset ages or policies.
Students take the numbers at face value.
Fix: Mention that older assets with low book value inflate ROCE and that accounting policies may differ.

Worked examples

Example 1

Division A has revenue of $2,000,000, operating profit of $300,000 and capital employed of $1,000,000. Division B has revenue of $1,200,000, operating profit of $240,000 and capital employed of $800,000. Compare the divisions using ROCE, operating margin and asset turnover.

Show the solution

Division A ROCE = 300,000 ÷ 1,000,000 = 30%.
Division B ROCE = 240,000 ÷ 800,000 = 30%.
Division A operating margin = 300,000 ÷ 2,000,000 = 15%.
Division B operating margin = 240,000 ÷ 1,200,000 = 20%.
Division A asset turnover = 2,000,000 ÷ 1,000,000 = 2.0 times.
Division B asset turnover = 1,200,000 ÷ 800,000 = 1.5 times.
Check: A: 15% × 2.0 = 30%. B: 20% × 1.5 = 30%.

Answer: Both divisions earn a ROCE of 30%, but in different ways. Division A has a lower margin (15%) and higher asset turnover (2.0 times), suggesting high volume at lower prices. Division B has a higher margin (20%) and lower turnover (1.5 times), suggesting premium pricing or tighter cost control with less use of assets. Further information on the causes would be needed.

Example 2

A company has revenue of $900,000, cost of sales of $540,000, inventory of $90,000, trade receivables of $135,000, trade payables of $72,000, current assets of $270,000 and current liabilities of $180,000. Calculate gross margin, current ratio, quick ratio, inventory days, receivables days and payables days. Use 365 days and assume all sales are on credit.

Show the solution

Gross profit = 900,000 − 540,000 = 360,000. Gross margin = 360,000 ÷ 900,000 = 40%.
Current ratio = 270,000 ÷ 180,000 = 1.5.
Quick ratio = (270,000 − 90,000) ÷ 180,000 = 1.0.
Inventory days = 90,000 ÷ 540,000 × 365 = 60.8 days.
Receivables days = 135,000 ÷ 900,000 × 365 = 54.75 days, about 55 days.
Payables days = 72,000 ÷ 540,000 × 365 = 48.7 days.

Answer: Gross margin 40%; current ratio 1.5; quick ratio 1.0; inventory days about 61; receivables days about 55; payables days about 49. The company collects cash from customers about 6 days slower than it pays suppliers (55 vs 49), and holds inventory for about 61 days, so it has a long working capital cycle that needs financing.

Exam tips

In Section C, aim for a calculation, a number-based comment and a reason for each key ratio. Comments earn most of the marks.
In Section A and B objective questions, check the exact definition in the question and which denominator to use. A wrong answer scores zero.
Show formulas and workings, so you can earn credit for method in constructed response answers even if an input is wrong.
Use the ROCE = margin × turnover link whenever you must explain a change in return.
Always add a limitation, such as no industry data, one year only or different accounting policies.

Ratio Analysis in Performance Evaluation: frequently asked questions

Which ratios matter most in ACCA PM?

ROCE, operating margin, asset turnover, gross margin and working capital days appear most often in performance evaluation. Liquidity and gearing are added when risk is part of the question. Learn to link them rather than treat each in isolation.

How do I interpret a fall in ROCE?

Split ROCE into operating margin and asset turnover. See which fell. A margin fall points to price or cost issues, while a turnover fall points to new assets not yet earning or weaker sales.

Should I use closing or average capital employed?

Follow the question. If it gives no instruction, use closing figures and say so. Whichever you choose, apply it consistently across all years or divisions.

What are the limitations of ratio analysis?

Ratios use historic data and can be distorted by different accounting policies, inflation and year-end timing. They need a sensible comparator and they ignore non-financial factors such as quality or staff morale.
