Explain the purpose and main parts of an income statement, calculate gross profit and profit for the year, and explain how profit can be used or improved

What this dot point is asking

This outcome wants you to explain the purpose and main parts of an income statement (also called the profit and loss account), to calculate gross profit and profit for the year (net profit), and to explain how profit can be used or improved. The central idea is that the income statement shows whether a business made a profit or loss over a period, by setting its revenue against its costs in a clear order.

The answer

Purpose of the income statement

An income statement shows a firm's revenue, costs and profit (or loss) over a period, usually a year. Its purpose is to show how much profit the business made and how it was made, so that owners, investors, lenders and managers can judge performance and make decisions.

Main parts of the income statement

The statement works down from sales to profit:

• Revenue (sales turnover) - the money earned from selling goods or services.
• Cost of sales - the direct cost of the goods sold (materials, the cost of buying stock).
• Gross profit = revenue minus cost of sales.
• Expenses (overheads) - indirect running costs such as rent, wages, utilities and advertising.
• Profit for the year (net profit) = gross profit minus expenses.

Gross profit and profit for the year

Gross profit is the profit from trading before overheads. Profit for the year is what is left after all costs, the figure the owners actually keep. A firm can have a strong gross profit but a low profit for the year if its overheads are high.

How profit is used

Profit can be:

• Retained in the business (an internal source of finance for growth).
• Distributed to owners (drawings for a sole trader, dividends for shareholders).
• Used to repay debt or build reserves.

How profit can be improved

• Increase revenue - sell more, or raise price where demand allows.
• Reduce cost of sales - cheaper suppliers, less waste (raises gross profit).
• Reduce expenses - lower rent, utilities or admin (raises profit for the year).

Examples in context

Example 1. A cafe with high rent. A Singapore cafe has strong sales and a good gross profit, but its mall rent and staff costs are very high, so its profit for the year is small. Reading its income statement, the owner sees that overheads, not trading, are the issue, and decides to renegotiate rent and improve staff scheduling. This shows how the split between gross profit and net profit pinpoints whether a firm's problem lies in trading or in overheads.

Example 2. Improving the gross margin. A clothing retailer finds its gross profit is thin because it buys stock at high prices. It switches to a cheaper supplier and reduces markdowns, raising the gross profit on each item. Because expenses are unchanged, the higher gross profit flows straight through to a higher profit for the year. The example shows how cutting the cost of sales lifts both profit figures, a direct use of the income statement structure.

Try this

Q1. State the formula for gross profit. [2 marks]

• Cue. Gross profit = revenue (sales) minus cost of sales (the direct cost of the goods sold).

Q2. Revenue is $80,000, cost of sales is$50,000, and expenses are $20,000. Calculate the profit for the year. [2 marks]

• Cue. Gross profit = \80{,}000 - \50{,}000 = \30{,}000$; profit for the year =$\30{,}000 - \20{,}000 = \$10{,}000$.

Q3. Explain the difference between gross profit and profit for the year. [4 marks]

• Cue. Gross profit is revenue minus the cost of sales, so it measures the profit made from trading before any overheads are taken off. Profit for the year is gross profit minus all the expenses (overheads) such as rent, wages and utilities, so it is what the business actually keeps after every cost. A firm can have a healthy gross profit but a low profit for the year if its expenses are high, which is why both figures are shown and compared.
