Introduction

The accounting equation forms the core of double-entry bookkeeping, providing a clear structure for recording and classifying financial transactions. Every transaction affects the equation in a way that keeps the balances in check. To use the accounting equation, you must understand the key elements: assets, liabilities, equity (also called capital), income, and expenses. Each element serves a specific purpose in representing the business’s financial position and performance.

Key Term: accounting equation
A formula expressing the relationship between a business’s assets, liabilities, and equity: Assets = Equity + Liabilities.

The Elements of Financial Statements

Correct recognition and classification of items is essential in accounting. There are five basic elements, each with a distinct definition:

• Assets are resources owned or controlled by the business that are expected to bring future benefits. Examples include cash, equipment, and receivables.
• Liabilities are present obligations to transfer economic resources to other parties as a result of past transactions. Examples include amounts owed to suppliers and bank loans.
• Equity (Capital) represents the residual interest in the assets of the business after deducting all liabilities. For a sole trader, this is the owner’s capital.
• Income is an increase in economic benefits, such as money received from sales, which increases equity.
• Expenses represent decreases in economic benefits, such as costs incurred to operate the business, which reduce equity.

Key Term: asset
A present economic resource controlled by the business due to past events, from which future benefits are expected.

Key Term: liability
A present obligation to transfer an economic resource as a result of past events.

Key Term: equity
The owner’s residual interest in the business’s assets after liabilities are settled.

Key Term: income
Increases in economic benefits that result in an increase in equity, excluding contributions from the owner.

Key Term: expense
Decreases in economic benefits that cause a reduction in equity, excluding withdrawals by the owner.

The Accounting Equation in Practice

The accounting equation ensures that all entries in the accounting system are balanced. Every financial transaction must keep the equation true.

Core equation:
Assets = Equity + Liabilities

This can be rearranged if needed, but the fundamental relationship does not change. Equity is sometimes expanded to show how income and expenses affect it:

Expanded equation:
Assets = Opening equity + Income – Expenses + Liabilities

Worked Example 1.1

A business owner starts a business by investing £8,000 cash. The business then takes out a bank loan for £2,000 and buys inventory for £3,000 cash.

Question: Use the accounting equation to show the financial position after these transactions.

Answer:

1. Owner invests £8,000:
   • Assets (cash): +£8,000
   • Equity: +£8,000
2. Bank loan of £2,000 received:
   • Assets (cash): +£2,000 (total cash = £10,000)
   • Liabilities: +£2,000
3. Buy inventory for £3,000 cash:
   • Assets: Cash –£3,000; Inventory +£3,000 (total assets remain £10,000)

Final equation:

Assets (Cash £7,000 + Inventory £3,000 = £10,000) = Equity (£8,000) + Liabilities (£2,000)

How Income and Expenses Affect Equity

In day-to-day business, most transactions affect income or expenses, which change equity (capital introduced by the owner):

• When the business earns income (e.g., makes a sale), assets increase (cash or receivable) and so does equity, via profit.
• When expenses are incurred (e.g., pay rent), assets decrease (less cash) and equity also decreases (profit falls).

This means:

• Profit increases equity.
• Losses and expenses reduce equity.

Worked Example 1.2

A business makes £4,000 in sales and incurs £1,500 in expenses (all paid in cash) during its first month.

Question: Show the impact on the accounting equation.

Answer:

• Sales:
  • Assets (cash): +£4,000
  • Income: +£4,000 (increase equity)
• Expenses:
  • Assets (cash): –£1,500
  • Expenses: –£1,500 (reduce equity)

Net effect:

Assets: Starting position +£2,500 (net cash = £4,000 in, £1,500 out).

Equity increases by net profit (£4,000 – £1,500 = £2,500).

Classifying Transactions by Element

When recording transactions, each must be recognised as an asset, liability, equity, income, or expense. Accurate classification is essential for correct double-entry and financial reporting.

Worked Example 1.3

Classify the following transactions for a retail business:

• Received £500 from a credit customer.
• Paid £80 for electricity.
• Purchased equipment worth £900 by bank loan.
• Owner withdrew £200 for personal use.

Question: State the type of each item.

Answer:

• £500 received: Asset (increase in cash), reduces receivables (asset).
• £80 electricity: Expense (reduces cash and equity).
• £900 equipment by loan: Asset (equipment increases), Liability (loan increases).
• £200 drawings: Reduces equity.

Exam Warning

Be careful not to confuse assets with expenses. Assets bring future benefit and are owned or controlled by the business, whereas expenses relate only to costs incurred during the accounting period without future benefit. Equipment purchased for use in the business is an asset; electricity used up is an expense.

Summary

The accounting equation is the fundamental expression of how assets, liabilities, and equity are related in accounting. Each business transaction affects at least two of these elements but keeps the equation balanced. Correct classification of assets, liabilities, equity, income, and expenses is necessary for accurate accounting records and financial statements.
