What are profitability ratios?

  • Profitability ratios assess a company's ability to earn profits from sales, operations or assets

    • They compare profits to other values such as revenue, costs and capital employed

  • The main profitability ratios are:

    • Gross profit margin

    • Mark-up

    • Profit margin

    • Return on capital employed

Gross profit margin

What is the gross profit margin?

What is the formula?

fraction numerator Gross space profit over denominator Revenue end fraction cross times 100

How should the value be written?

Write as a percentage (X%)

How should the value be rounded?

Round to two decimal places

What does the value mean?

The value represents the proportion of the revenue that is turned into gross profit

How can the ratio be improved?

  • Increase the selling price of the goods

  • Buy the goods from a cheaper supplier

  • If the gross profit margin decreases then this suggests that:

    • The goods are being sold at a cheaper price than in previous years

      • Allowing more trade discounts has the same effect

    • The costs of goods have increased but their selling price has remained the same

Examiner Tips and Tricks

The gross profit margin must be less than 100%. If you get an answer bigger than 100% then check your working.

Worked Example

Kaley is a sole trader. She provides the following information for the year ended 31 December 2023.

$

Revenue

128 000

Purchases

52 000

Inventory at 1 January 2023

8 000

Inventory at 31 December 2023

6 000

Calculate Kaley's gross profit margin. Your answer should be correct to two decimal places.

Answer:

  • Calculate the cost of sales

    • Opening inventory + Purchases - Closing inventory

$8 000 + $52 000 - $6 000 = $54 000

  • Calculate the gross profit

    • Revenue - Cost of sales

$128 000 - $54 000 = $74 000

  • Calculate the gross profit margin

    • fraction numerator Gross space profit over denominator Revenue end fraction cross times 100

fraction numerator 74 space 000 over denominator 128 space 000 end fraction cross times 100 equals 57.8125

  • Round to two decimal places

Gross profit margin = 57.81%

Mark-up

What is the mark-up?

What is the formula?

fraction numerator Gross space Profit over denominator Cost space of space sales end fraction cross times 100

How should the value be written?

Write as a percentage (X%)

How should the value be rounded?

Round to two decimal places

What does the value mean?

The value represents the percentage of the cost of sales that is added to the costs to form the selling price

How can the ratio be improved?

  • Increase the selling price of the goods

  • Buy the goods from a cheaper supplier

  • The mark-up is normally a fixed percentage applied to the cost of the goods

    • The percentage can be raised to increase profits

Examiner Tips and Tricks

The mark-up can be bigger than 100% so do not worry if your answer is bigger than 100%.

Worked Example

Kaley is a sole trader. She provides the following information for the year ended 31 December 2023.

$

Revenue

128 000

Purchases

52 000

Inventory at 1 January 2023

8 000

Inventory at 31 December 2023

6 000

Calculate Kaley's mark-up. Your answer should be correct to two decimal places.

Answer:

  • Calculate the cost of sales

    • Opening inventory + Purchases - Closing inventory

$8 000 + $52 000 - $6 000 = $54 000

  • Calculate the gross profit

    • Revenue - Cost of sales

$128 000 - $54 000 = $74 000

  • Calculate the mark-up

    • fraction numerator Gross space profit over denominator Cost space of space sales end fraction cross times 100

fraction numerator 74 space 000 over denominator 54 space 000 end fraction cross times 100 equals 137.0370...

  • Round to two decimal places

Mark-up = 137.04%

Profit margin

What is the profit margin?

What is the formula?

fraction numerator Profit space for space the space year over denominator Revenue end fraction cross times 100

How should the value be written?

Write as a percentage (X%)

How should the value be rounded?

Round to two decimal places

What does the value mean?

The value represents the proportion of the revenue that is turned into profit for the year

How can the ratio be improved?

  • Increase the gross profit

    • Increase selling prices

    • Buy goods from cheaper suppliers

  • Increase income from other sources

  • Reduce expenses such as staff salaries, marketing or administrative costs

  • A decreasing profit margin suggests that:

    • Gross profit has decreased from previous years

    • The business is paying more for expenses

    • The business is not earning as much other income as in previous years

Worked Example

Kaley is a sole trader. She provides the following information for the year ended 31 December 2023.

$

Revenue

128 000

Gross profit for the year

74 000

Other income

9 000

Expenses

46 000

Calculate Kaley's profit margin. Your answer should be correct to two decimal places.

Answer:

  • Calculate the profit for the year

    • Gross profit + Other income - Expenses

$74 000 + $9 000 - $46 000 = $37 000

  • Calculate the profit margin

    • fraction numerator Profit space for space the space year over denominator Revenue end fraction cross times 100

fraction numerator 37 space 000 over denominator 128 space 000 end fraction cross times 100 equals 28.90625

  • Round to two decimal places

Profit margin = 28.91%

Return on capital employed (ROCE)

What is the return on capital employed (ROCE)?

What is the formula?

fraction numerator Profit space for space the space year space before space interest over denominator Capital space employed end fraction cross times 100

 

Capital employed = Equity (or capital) + Non-current liabilities

How should the value be written?

Write as a percentage (X%)

How should the value be rounded?

Round to two decimal places

What does the value mean?

The value represents the proportion of the capital employed that is turned into profits

How can the ratio be improved?

  • Increase the profit for the year

    • Increase income

    • Decrease expenses

  • Reduce non-current liabilities such as bank loans

  • A business aims to increase the return on capital employed

    • The business should consider whether it can use more short-term sources of finance rather than long-term loans

Examiner Tips and Tricks

Notice that this profitability ratio uses the operating profit rather than the profit for the year. This means you need to use the profit before finance costs (loan interest or debenture interest).

Worked Example

The equity and liabilities of Khazam Ltd at 31 December 2023 are listed below.

$

Ordinary share capital

140 000

General reserve

40 000

Retained earnings

50 000

5% Debentures

30 000

Trade payables

25 000

The profit for the year ended 31 December 2023 was $35 000 after charging debenture interest.

Calculate the return on capital employed for the year ended 31 December 2023. The calculation should be correct to two decimal places.

Answer:

  • Calculate the debenture interest for the year

5% × $30 000 = $1 500

  • Calculate the profit for the year before interest

    • Add the debenture interest back onto the profit for the year

$1 500 + $35 000 = $36 500

  • Calculate the capital employed

    • Equity (Issued share capital + Reserves + Retained earnings) + Non-current liabilities

$140 000 + $40 000 + $50 000 + $30 000 = $260 000

  • Calculate the return on capital employed

    • fraction numerator Profit space for space the space year space before space interest over denominator Capital space employed end fraction cross times 100

fraction numerator 36 space 500 over denominator 260 space 000 end fraction cross times 100 equals 14.0384...

  • Round to two decimal places

ROCE = 14.04%
