Explain the concept of ‘double entry’ with reference to the accounting equation.

The concept of 'double entry' is a fundamental principle in the field of accounting. It states that every financial transaction has equal and opposite effects in at least two different accounts. This principle keeps the accounting equation (Assets = Liabilities + Equity) in balance.

Let's break it down:

1. Assets: These are resources owned by a business which are expected to generate future benefits. Examples include cash, inventory, buildings, etc.

2. Liabilities: These are obligations of a business, amounts that it owes to others. Examples include loans, accounts payable, etc.

3. Equity: Also known as capital or net assets, it represents the residual interest in the assets of the entity after deducting liabilities. In other words, equity represents the value of an asset after all liabilities have been paid off.

Now, let's consider a simple example to understand the double entry system:

Suppose a business takes a loan of $10,000 from a bank. Here, the business's cash account (an asset) increases by$10,000. Simultaneously, its loan account (a liability) also increases by $10,000. This is the double entry - one entry is made to an asset account (debit), and another entry is made to a liability account (credit).

So, the accounting equation after this transaction would be:

Assets ($10,000) = Liabilities ($10,000) + Equity ($0)

This equation always remains in balance due to the double entry system. Every transaction affects at least two accounts, and the total debits always equal the total credits. This ensures the accuracy of the financial statements and helps detect errors.
