Matching Concept

The central idea of the Matching Concept is simple: to find the true profit or loss for a period, you must pair the revenue earned in that period with the expenses that were necessary to earn that same revenue. You cannot mix up revenues from one year with expenses from another year and call the result a meaningful profit.

Profit is not just cash left over. It is the surplus of revenue earned over the expenses incurred to earn that revenue, both belonging to the same accounting period.

Revenue and Expense Recognition: Accrual, Not Cash

The concept builds directly on the accrual basis of accounting. Revenue is recognised when the sale is complete or the service is rendered — not when cash is received. Similarly, an expense is recognised when an asset or service has been used to generate revenue — not when cash is paid.

This means you record the expense in the period it helps earn revenue, regardless of when the cash actually leaves the business.

Practical Examples of Matching

• Salaries, Rent, Insurance: These are recognised as expenses in the period to which they relate. If you pay rent in April for the month of March, that rent is an expense of March, not April. The cash payment date is irrelevant.
• Depreciation: A fixed asset (like a machine) is used over many years to generate revenue. Its cost cannot be charged as an expense in the year of purchase. Instead, the cost is divided (depreciated) over the periods during which the asset is used. Each year, a portion of the asset's cost is matched against the revenue that the asset helped generate that year.

The Critical Case: Cost of Goods Sold

This is the most important application of the matching concept for a trading business. When calculating profit for a year, you cannot take the cost of all goods purchased or produced during that year.

You must only consider the cost of goods that have actually been sold during that year. The cost of goods that remain unsold at the end of the year is not an expense of the current year — it is an asset (closing stock) that will be matched against the revenue of the next year when those goods are sold.

The Core Rule of the Matching Concept

The concept leads to a single, non-negotiable rule for profit determination: …
