The accounting equation · Cambridge IGCSE Accounting (9

In plain words

Everything a business has was paid for by somebody: either the owner, or someone the business still owes. That simple idea is the accounting equation, and all of double entry grows out of it.

6 things to know

Assets are things owned by the business, or owed to it: premises, equipment, inventory, trade receivables, money in the bank.
Liabilities are amounts the business owes to others: trade payables, loans, a bank overdraft.
Owner's equity (capital) is what the business owes to its owner: the money the owner put in, plus profits, less drawings.
The accounting equation: assets = owner's equity + liabilities. Rearranged: owner's equity = assets − liabilities.
Every transaction changes two things, and the equation still balances afterwards.
Profit increases owner's equity. A loss and drawings reduce it.

Worked example

A business has assets of $54 000 and liabilities of $16 500. Find the owner's equity. It then buys equipment for $3000 on credit. Show that the equation still balances.

Owner's equity = assets − liabilities = 54 000 − 16 500 = $37 500.
Buying equipment adds an asset: assets become $57 000.
It was bought on credit, so a liability is added too: liabilities become $19 500.
57 000 = 37 500 + 19 500. It balances, and the owner's equity has not changed.

Tips and tricks

Think about each transaction as two changes. If only one side of the equation has moved, you have missed one.
Buying an asset on credit does not change owner's equity. Only profit, loss, new capital and drawings do.
