PART ONE
Gross and Net Profit
Two measures of profit, telling two different stories.
openrevise.com
EDEXCEL GCSE BUSINESS · PAPER 2
Gross Profit
Making financial decisions
Lesson 1 of 2
Gross profit = sales revenue - cost of sales.
Sales revenue
The money received from selling products.
Cost of sales
The direct cost of making or buying the products that were sold - raw materials, stock bought to sell and production wages.
What it shows
How much profit the business makes from its products, before paying for everything else.
Example
Bright Bikes sells £500,000 of bikes. The bikes and parts it sold cost £300,000. Gross profit = £500,000 - £300,000 = £200,000.

EDEXCEL GCSE BUSINESS · PAPER 2
Net Profit
Making financial decisions
Lesson 1 of 2
Net profit = gross profit - other operating expenses and interest.
Other operating expenses
The costs of running the business that are not part of cost of sales - rent, salaries of office staff, marketing, insurance and utilities.
Interest
The cost of borrowing - interest paid on loans and overdrafts.
What it shows
The true profit left for the owners after every cost has been paid.
Example
Bright Bikes' other operating expenses are £120,000 and it pays £10,000 interest. Net profit = £200,000 - £120,000 - £10,000 = £70,000.

Reading the Accounts
Making financial decisions
Lesson 1 of 2
Gross profit, net profit and margins tell an owner how the business is really doing.
Revenue alone tells an owner little. Gross profit shows whether the business is buying and making its products at the right cost; net profit shows whether it is controlling everything else. The margins let the owner compare one year with another.

Profit Margins
Turning profit into a percentage.
openrevise.com
EDEXCEL GCSE BUSINESS · PAPER 2
Gross Profit Margin
Making financial decisions
Lesson 1 of 2
Gross profit margin (%) = (gross profit ÷ sales revenue) × 100.
What it shows
How many pence of gross profit the business makes from every £1 of sales.
A higher margin
Means the business buys or makes its products cheaply compared with its selling price.
How to improve it
Raise prices, or find cheaper suppliers and cut the cost of sales.

Bright Bikes' Gross Profit Margin
Making financial decisions
Lesson 1 of 2
Divide, then multiply by 100.
Bright Bikes' gross profit is £200,000 and its sales revenue is £500,000. Calculate its gross profit margin.
1
Write the formula
GPM = (gross profit ÷ sales revenue) × 100
2
Put in the numbers
= (£200,000 ÷ £500,000) × 100
3
Work it out
= 0.4 × 100 = 40%
ANSWER
Gross profit margin = 40%
openrevise.com
EDEXCEL GCSE BUSINESS · PAPER 2
Net Profit Margin
Making financial decisions
Lesson 1 of 2
Net profit margin (%) = (net profit ÷ sales revenue) × 100.
What it shows
How many pence of net profit the business keeps from every £1 of sales, after all costs.
A higher margin
Means the business controls its costs well.
The gap between margins
A big gap between gross and net margin means operating expenses and interest are taking a large share - a sign to control overheads.

Bright Bikes' Net Profit Margin

= (£70,000 ÷ £500,000) × 100
3
Work it out
= 0.14 × 100 = 14%
ANSWER
Net profit margin = 14%

CASE STUDY
Supermarkets: Pennies in the Pound
The UK's big supermarkets sell billions of pounds of food and household goods every year, but their net profit margins are usually very low - often just a few pence of profit for every pound customers spend. Competition on price is fierce, so they keep prices low and make their profit through enormous sales volumes. A luxury brand, by contrast, may sell far less but keep a much larger share of every pound as profit. Comparing margins, not just profit in pounds, shows how differently businesses make their money.
