The gross profit margin

  • This calculation shows the proportion of revenue that is turned into gross profit

    • It is calculated using the following formula and is expressed as a percentage

 Gross profit margin = Gross profitSales revenue× 100      

Improving the gross profit margin

  • The gross profit margin can be improved in two ways

    • The business can increase its sales revenue

    • The business can reduce its direct costs

How to increase the gross profit margin

Method

Explanation

Increase sales revenue

1. Increase the value of sales

  • Raise prices

    • If costs remain the same, this will improve profitability as the difference between the selling price and costs is now greater

  • Sell premium products

    • If customers are willing to spend money on these goods, the business could earn more profit per item sold

2. Increase the volume of sales

  • Price tactics 

    • Use price tactics to encourage higher quantity or more frequent purchases

      • E.g. 'Buy one get one half price' doubles the number of items a customer purchases, increasing revenue

  • Increase marketing activities

    • Engage in more marketing activities to increase sales volume

Reduce direct costs

  • Reduce variable costs 

    • This may involve purchasing cheaper/alternative resources, negotiating with suppliers or purchasing in bulk

    • Businesses must ensure that reducing variable costs will not have an adverse effect on the quality or desirability of products

    • Buying stock in greater quantities may require investment in increased storage space which will reduce the impact of the cost savings made

  • Businesses may also be able to reduce wastage of raw materials and components 

Worked Example

Head to Toe Wellbeing’s revenue in 2022 was $124,653. Its gross profit was $105,731

Calculate Head to Toe Wellbeing Ltd’s Gross Profit Margin in 2022

(2)

Step 1: Substitute the values into the formula

Gross profit = Gross profit Sales revenue × 100   = $105,731 $124,653 =  0.8482    [1]

Step 2: Multiply the outcome by 100 to find the percentage

= 0.8482 × 100= 84.82%      [1]

  • 84.82% of Head to Toe Wellbeing’s revenue was converted into gross profit during 2022

The net profit margin

  • The Net Profit Margin shows the proportion of revenue that is turned into profit before interest and tax

    • It is calculated using the formula below and the outcome is expressed as a percentage

Net profit margin = Profit before interest and taxSales revenue×100

Improving the net profit margin

  • The profit margin can be improved in two ways

    • Increasing the gross profit margin (see above)

    • Reducing overhead costs by reducing staffing levels, relocating to cheaper premises or changing utility companies

      • Reducing staffing levels may affect staff morale and negatively affect productivity

      • Relocation costs can outweigh some of the benefits of moving to a cheaper location

      • Replacing inefficient or outdated equipment may require staff training

Worked Example

Head to Toe Wellbeing’s revenue in 2022 was $124,653. Its profit before interest and tax was $65,864

Calculate Head to Toe Wellbeing Ltd’s Profit Margin in 2022

(2)

Step 1: Substitute the values into the formula

Net profit margin = Profit before interest and taxSales revenue×100= $65,864$124,653= 0.5284    [1]

Step 2: Multiply the outcome by 100 to find the percentage

 

= 0.5284 × 100= 52.84%     [1]

  • In 2022, 52.84% of Head to Toe Wellbeing’s revenue was converted into profit before interest and tax

Return on capital employed

  • The return on capital employed (RoCE) measures how how effectively a business uses the capital invested in the business to generate profit

    • It is calculated using the formula below and is expressed as a percentage

Return on capital employed = Profit before interest and taxCapital employed  × 100

  • RoCE be compared over time and with competitors

    • It can also be compared with other potential capital investments, such as savings rates

  • The capital employed figure is usually provided for you

    • If required, it is calculated using the formula

Capital employed = Noncurrent liabilities + Equity

Improving RoCE

  • When analysing the RoCE, the higher the rate the better, as it indicates that the business is profitable and using its capital efficiently

    • Investors prefer businesses with stable and rising levels of RoCE, as this indicates low-risk growth is being achieved

    • A ROCE of at least 20 per cent is usually a good sign that the company is in a good financial position

  • To increase the RoCE, a business can

    • Increase the level of profit generated without introducing new capital into the business

    • Maintain the level of profit generated whilst reducing the amount of capital in the business

Worked Example

The table shows an extract from the company accounts of Keals Cosmetics.

Non-current Liabilities

€1.5 million

Revenue

€7 million

Equity

€15.4 million

Profit before Interest & Tax

€2.2 million

Calculate Keals Cosmetics' Return on Capital Employed.         

(3)

 Step 1: Calculate the capital employed   

Capital employed = Noncurrent liabilities + EquityCapital employed = 1.5 m + 15.4 mCapital employed = 16.9 m   [1]

Step 2: Divide Operating Profit by Capital Employed

RoCE = Profit before interest and taxCapital employed × 100= 2.2 m16.9 m × 100= 0.13  [1]

Step 3: Multiply the result by 100 and express the outcome as a percentage

= 0.13 × 100= 13%   [1 mark]

  • Capital employed in Keals Cosmetics has generated a return of 13%

Using RoCE to make decisions

  • RoCE can be used to support strategic decisions (e.g. investment or divestment decisions) to determine the most profitable option given the level of capital employed

Worked Example

Faced with increasing costs, Kent & Medway Properties Ltd is looking to close one of its three high-street estate agency branches.

The table below shows some key data for each of the branches.

Branch

Capital employed 

Profit before interest and tax

Sevenoaks

£2.4m

£0.37m

Whitstable

£3.1m

£0.57m

Rochester

£2.9m

£0.51m

Calculate the Return on Capital Employed (RoCE) for each branch and recommend which branch, on profitability terms, should close.

(5)

Step 1: Apply the formula to calculate the RoCE for each branch

      RoCE= Profit before interest and taxCapital employed  × 100RoCE Sevenoaks = £0.37m£2.4m  × 100 = 15.42%   [1]

RoCE Whitstable = £0.57m£3.1m  × 100 = 18.39% [1]

RoCE Rochester = £0.51m£2.9m  × 100 = 17.59% [1]

Step 2: Identify the least profitable branch for closure

  • Sevenoaks is the least profitable branch with a RoCE of 15.42% and should be the branch selected for closure   [2]

Examiner Tips and Tricks

When calculating financial ratios check that you are using the correct units.

In some cases financial data is presented as raw figures (e.g. £14,520) but in most cases, you will be working in thousands (£000) or millions (£m).

  • Ensure that you convert correctly, e.g. £0.39 million is equal to £390,000 and £34.9 (000) is equal to £34,900

  • Make sure the decimal place is in the correct place

  • Calculate to two decimal places unless stated otherwise
