Income Statement (AS Level) Financial accounting

 

The Income Statement (sometimes referred to as the Statement of Profit or Loss) is the primary document used to determine a business’s performance over a specific period. Chapter 7 of the sources is dedicated entirely to this subject.

 Purpose and Nature of the Income Statement

An income statement is an account prepared periodically to find the profit or loss made by a business. For a sole trader (an owner who runs the business alone, responsible for debts and entitled solely to the profit), its preparation is critical for evaluating performance:

• Profit Determination: The statement compares the revenue earned by the business with its expenses. If revenue exceeds expenses, the business has made a profit; if expenses exceed revenue, it has made a loss.
• Period Statement: The statement is known as a period statement because it covers a specified period of time, typically one complete year, which must be clearly stated in the heading.
• Double-Entry Integration: The income statement is part of the double-entry model. Ledger account balances are transferred to the income statement via journal entry, effectively closing those nominal accounts for the period.

 Steps for Preparing the Income Statement

The preparation follows a logical sequence, assuming a trading business (one that buys and sells goods):

1. Prepare the Trial Balance: All ledger accounts must first be balanced, and a trial balance prepared at the date to which the income statement is required.
2. Transfer Nominal Accounts: The balances on nominal accounts (revenue, other income, and expenses) are transferred to the income statement.
3. Prepare the Trading Section: This section calculates the Gross Profit.
4. Prepare the Operating Section: This section incorporates other income and expenses to calculate the final Profit for the year.

 Structure of the Income Statement

The statement is constructed to clearly separate the profit generated from core trading (Gross Profit) from overall business performance (Profit for the Year).

1. Trading Section (Calculating Gross Profit)

This section focuses on the cost and revenue directly related to the goods sold:

Item	Calculation Detail
Revenue (Sales)	Total sales, less any Sales returns. This figure is also known as revenue or turnover.
Cost of Sales	The net cost of goods sold. This calculation structure is crucial:
Opening Inventory	Inventory (unsold goods) at the beginning of the period.
Add: Purchases	Purchases made during the period. Must deduct Purchases returns.
Add: Carriage Inwards	Carriage inwards (delivery cost to bring goods into the business) is added to purchases as it is part of the cost of the goods.
Less: Drawings (Goods)	Goods taken by the owner for personal use must be deducted from purchases at cost price and transferred to the Drawings account.
Less: Closing Inventory	Inventory remaining unsold at the end of the period is deducted from the goods available for selling.
Gross Profit	Calculated as Revenue minus Cost of Sales.

2. Operating Section (Calculating Profit for the Year)

This section adjusts the gross profit for other operational activities, income, and non-trading expenses:

Section	Detail
Add: Other Income	Income not derived directly from core sales (e.g., Discounts received, Rent receivable, Interest received). Other income should always be added to the gross profit, not treated as a negative expense.
Less: Expenses (Overheads)	Day-to-day costs incurred in running the business (revenue expenditure/expense). Examples include Wages and salaries, Rent payable, Discounts allowed, Insurance, and Carriage outwards (cost of delivering sold goods to customers).
Profit for the Year	The final result, sometimes called ‘the bottom line’. This figure is carried to the owner's Capital account in the Statement of Financial Position.

If the business is a service business (e.g., an accountant) that does not buy and sell goods, there will be no cost of sales section; the statement will only show the income (fees received) less expenses to determine the profit for the year.

 Presentation Styles

Income statements were historically prepared in horizontal form (with debit and credit sides, similar to a ledger account). However, the vertical form (listing information down the page) is now standard because it is easier for non-accountants to understand.

Key Presentation Tips:

• Always include a proper heading specifying the trader's name and the period covered ("for the year ended...").
• The words ‘cost of sales’ and ‘gross profit’ should always be explicitly included.
• For sole traders, expenses can be listed in any order, though grouping similar expenses (like property costs) or listing the largest expenses first is often recommended.
