Income statement of a sole trader

🎬 The doodle video for this lesson is coming soon. Subscribe on YouTube to see it first.

The income statement shows whether a business made a profit or a loss over the year.

Cost of sales and gross profit

Revenue (sales less sales returns)
less cost of sales = gross profit
Cost of sales = opening inventory + purchases (less purchases returns, plus carriage inwards) − closing inventory

Profit for the year

Gross profit
add other income (such as discount received, rent received)
less expenses (such as wages, rent, insurance, carriage outwards, depreciation, irrecoverable debts)
= profit for the year (or loss).

An example

Worked example

Revenue £80 000, opening inventory £5000, purchases £50 000, closing inventory £7000. Find the gross profit.

  1. Cost of sales = 5000 + 50 000 − 7000 = £48 000
  2. Gross profit = 80 000 − 48 000

Answer: £32 000

Key idea

Cost of sales = opening inventory + net purchases (+ carriage inwards) − closing inventory. Gross profit = revenue − cost of sales. Profit for the year = gross profit + other income − expenses.
