Interpretation of Accounting Ratios

Calculating a ratio is only the first step. In an exam answer, the important skill is to interpret whether performance or financial position has improved or worsened, compare the ratio with useful information, explain the meaning, and suggest a possible cause or action.

Four step accounting ratio interpretation process

Topic 1: Why Ratio Interpretation Matters

Ratios become useful when they are compared, explained and linked to possible business causes.

1. Why Interpret Accounting Ratios?

Accounting ratios must be interpreted to decide whether the performance or financial position of a business has improved or worsened. Absolute figures on their own can sometimes be misleading.

Example: Working capital can hide a liquidity problem

20182019
Current assets$10,000$20,000
Current liabilities$5,000$15,000
Working capital$5,000$5,000
Current ratio2 : 11.33 : 1
Working capital is the same in both years, but liquidity has actually worsened because the current ratio has fallen from 2 : 1 to 1.33 : 1.

2. What Should Ratios Be Compared With?

A ratio becomes much more useful when compared with:

Weak answer

Gross margin = 40%.

Better interpretation

Gross margin increased from 35% to 40%, so the business is earning $5 more gross profit for every $100 of sales.

Topic 2: Profitability Ratios

Profitability ratios help judge how successfully the business earns profit from sales and capital.

3. Profitability Ratios

The chapter identifies three important profitability ratios:

Gross margin

Focuses on gross profit earned from sales.

Profit margin

Focuses on profit for the year earned from sales.

ROCE

Focuses on the return earned from capital employed.

In general, higher profitability ratios are better, but they should never be considered in isolation.

4. Interpreting Gross Margin

Gross Margin = Gross Profit ÷ Sales × 100

A higher gross margin means the business is making more gross profit from every $100 of sales.

Example
2018 gross margin = 50%
2019 gross margin = 60%
The business now earns $60 gross profit per $100 sales instead of $50 per $100 sales. Therefore, gross margin has improved.

5. Why Might Gross Margin Fall?

6. Improving Gross Margin

Reduce cost of sales

  • Find cheaper suppliers.
  • Negotiate bulk discounts.
  • Reduce carriage inwards.

Increase selling price

If costs remain unchanged, a higher selling price can increase gross margin.

Improve inventory management

Avoid excessive inventory which may deteriorate, become outdated, go out of fashion, or be damaged or stolen.

Every action has possible disadvantages. Cheaper goods may reduce quality, while higher selling prices may cause customers to switch to competitors.

7. Interpreting Profit Margin

Profit Margin = Profit for the Year ÷ Sales × 100

Profit margin considers not only cost of sales but also the business’s expenses.

Example
2018 profit margin = 30%
2019 profit margin = 33.33%
For every $100 of sales, 2018 profit was $30 and 2019 profit was $33.33. Therefore, profitability has improved.

8. Improving Profit Margin

Because profit margin is affected by expenses, a business may improve it by:

9. Gross Margin vs Profit Margin

The difference between gross margin and profit margin provides information about expense control.

Example
Gross margin = 50%
Profit margin = 30%
Difference = 50% − 30% = 20%
This suggests that expenses amount to approximately 20% of sales, assuming there is no other income.
Gross margin tells us about cost of sales. Profit margin also tells us about expenses. A large or increasing gap may indicate that expenses are becoming harder to control.

10. Interpreting ROCE

ROCE = Profit Before Interest ÷ Capital Employed × 100

ROCE measures how effectively the business uses its capital.

Example
2018 ROCE = 25.24%
2019 ROCE = approximately 20.22%
Although profit may have increased, ROCE has fallen because much more capital is being employed. The business is getting a lower return from every $100 invested.
Ways of improving gross profit and profit for the year may also improve ROCE.

Topic 3: Liquidity Ratios and Cash Position

Liquidity ratios judge whether the business can pay short-term debts when they fall due.

11. Interpreting the Current Ratio

The current ratio measures the ability of the business to meet its current liabilities.

Example
2018 = 2.4 : 1
2019 = 2 : 1
Although the ratio has fallen slightly, the textbook considers approximately 1.5 : 1 to 2 : 1 desirable for many businesses. Therefore, a movement closer to this range may actually represent an improvement.
A very high current ratio is not always good. It may indicate that too much money is tied up in current assets instead of being used productively.

12. Interpreting the Liquid Ratio

Liquid Ratio = (Current Assets − Inventory) ÷ Current Liabilities

A fall in the liquid ratio means the business has fewer liquid assets available to meet current liabilities.

Example
2018 = 1.4 : 1
2019 = 0.63 : 1
This is a significant deterioration in liquidity and may indicate a liquidity crisis. The textbook uses approximately 1 : 1 as a desirable liquid ratio.

13. Improving Working Capital and Cash Position

Working Capital = Current Assets − Current Liabilities

Improve working capital

  • Owner introduces more capital.
  • Reduce drawings.
  • Obtain a long-term loan.
  • Sell surplus non-current assets.

Improve cash

  • Increase cash sales.
  • Reduce credit sales.
  • Shorten the credit period allowed to customers.
  • Delay payment to trade payables.
These methods can have disadvantages. Delaying suppliers may damage relationships or lead to charges for late payment.

Topic 4: Efficiency Ratios

Efficiency ratios show how quickly inventory moves, customers pay and suppliers are paid.

14. Interpreting Trade Receivables Turnover

Trade receivables turnover shows how long customers take to pay.

Example
2018 = 30 days
2019 = 34 days
Customers are taking 4 days longer to pay. Therefore, the ratio has worsened slightly.

A high number of days may mean

  • Customers are paying slowly.
  • Credit control is weak.
  • Too much money is tied up in trade receivables.

To improve it

  • Chase customers more quickly.
  • Reduce credit periods.
  • Improve credit control.
  • Encourage prompt payment.

15. Interpreting Trade Payables Turnover

Trade payables turnover shows how long the business takes to pay suppliers.

Example
2018 = 61 days
2019 = 69 days
The business now takes about 8 days longer to pay its suppliers. This may suggest worsening liquidity or inefficient payment management.
Paying suppliers late may also mean losing cash discounts or being charged interest.

16. Interpreting Inventory Turnover

Inventory turnover measures how quickly inventory is sold and replaced.

Example
2018 = 7.4 times
2019 = 4 times
The business is now selling and replacing its inventory much more slowly. This is generally a deterioration.

Topic 5: Relationships That Change Ratios

Some accounting figures directly affect profitability and efficiency ratios.

17. Relationship Between Inventory and Profit

Closing inventory affects cost of sales, gross profit, gross margin, profit for the year, profit margin and inventory turnover.

If closing inventory is undervalued

Closing inventory too low → cost of sales too high.

  • Gross profit understated.
  • Gross margin understated.
  • Profit for the year understated.
  • Profit margin understated.

If closing inventory is overvalued

The opposite occurs.

  • Cost of sales understated.
  • Gross profit overstated.
  • Gross margin overstated.
  • Profit overstated.
  • Profit margin overstated.

18. Numerical Inventory Example

The textbook compares three possible closing inventory values to show how an incorrect inventory value can distort the ratios used to judge performance.

Closing inventoryGross profitGross marginProfitProfit margin
$4,000 – undervalued$3,50035%$1,00010%
$4,500 – correct$4,00040%$1,50015%
$5,000 – overvalued$4,50045%$2,00020%

19. Relationship Between Sales Revenue and Profit

Sales Revenue − Cost of Sales = Gross ProfitGross Profit − Expenses = Profit for the Year

If sales revenue is recorded incorrectly, then gross profit, profit for the year, gross margin and profit margin will also be incorrect.

20. Relationship Between Expenses and Profit

If expenses increase while everything else stays the same, profit for the year decreases and profit margin decreases. Gross margin may remain unchanged because gross margin is calculated before other expenses are deducted.

Example
Suppose gross margin remains 50%.
Profit margin changes from 16% in 2018 to 20% in 2019.
If sales remain constant, the improvement in profit margin indicates that expenses have decreased.

21. Relationship Between Profit and Owner’s Equity

Profit increases owner’s equity, while a loss decreases owner’s equity.

Closing Capital = Opening Capital + Profit + Capital Introduced − Drawings

Higher profit leads to higher owner’s equity, all else being equal. ROCE then compares profit before interest with the amount of capital employed.

Topic 6: How to Answer an Interpretation Question

Strong answers compare, explain and give a sensible cause or action.

22. How to Answer an Interpretation Question

A good exam answer should normally do three things:

  1. State the change. Example: Gross margin fell from 40% to 32%.
  2. Explain what it means. The business now earns only $32 gross profit for every $100 of sales compared with $40 previously.
  3. Suggest a possible reason or action. This could have resulted from higher purchase costs or lower selling prices. The business could negotiate lower prices with suppliers.
Avoid simply writing: “Gross margin got worse.” Explain how much, what it means, and why it may have happened.

Remember

Profitability
Gross margin falls → investigate selling price and cost of sales.
Profit margin falls → investigate gross profit and expenses.
ROCE falls → capital may not be generating enough profit.
Liquidity
Current ratio or liquid ratio falls → possible difficulty paying short-term debts.
Efficiency
Receivables days ↑ → customers slower to pay.
Payables days ↑ → business slower to pay suppliers.
Inventory turnover ↓ → inventory selling more slowly.
Most important exam skill: do not only calculate a ratio. Compare it, explain the change, identify possible causes and suggest suitable action.
