Income statements — common mistakes

Examiners look for precision. Do not confuse 'Revenue' with 'cash' or 'profit'. Revenue is the value of sales made in a period, whether or not the cash has been received yet. Always use the correct formula: Revenue - Cost of Sales = Gross Profit.

Show each line in calculations even if the question only asks for one figure — method marks are common. Use $ and thousands consistently with the case.

This is a common misconception. Profit is not the same as cash. Profit is an accounting measure of performance (Revenue - Costs) over a period. A business can be very profitable but have a negative cash flow if its customers (trade receivables) take a long time to pay their invoices. Conversely, a business could have positive cash flow but be unprofitable. Cash flow is tracked in the Statement of Cash Flows, not the Statement of Profit or Loss.

Operating Profit is arguably the most important indicator of a company's underlying operational health. It shows how well management is running the core business, generating profit from its primary activities, before the effects of its financing decisions (interest) and tax obligations. A strong and stable Operating Profit suggests a sustainable business model, whereas the final 'Profit for the Year' can be distorted by high debt levels (interest) or one-off tax effects.

Not necessarily. Increasing revenue is a positive sign, but it's only one part of the story. You must look further down the Statement of Profit or Loss. For example, did the Cost of Sales increase at a faster rate, causing the Gross Profit margin to shrink? Did the business spend heavily on marketing to achieve that revenue growth, causing Operating Profit to fall? A full analysis requires looking at the relationship between revenue, gross profit, and operating profit to judge overall performance.
