explain and apply the accounting equation

1.2 The Accounting Equation 📊

Objective

Explain the accounting equation and show how to apply it when recording business transactions.

What is the Accounting Equation?

Think of a balance scale that must always stay level. In accounting, the scale is the accounting equation:

$A = L + E$

  • Assets (A) – what the business owns (cash, equipment, inventory).
  • Liabilities (L) – what the business owes (loans, accounts payable).
  • Equity (E) – the owner’s claim on the business (capital, retained earnings).

Visualising the Equation with a Table

Assets (A) Liabilities (L) Equity (E)
$1,000 $400 $600

Applying the Equation – A Simple Example

A small café starts with:

  • Cash: $1,000
  • No loans or debts
  • Owner’s capital: $1,000
The equation holds: $1,000 = 0 + 1,000$.

The café then takes a loan of $400 and buys equipment for $400. How does the equation change?

  1. Loan increases Liabilities by $400.
  2. Equipment increases Assets by $400.
  3. Assets now: $1,400; Liabilities: $400; Equity remains $1,000.
  4. Check: $1,400 = $400 + $1,000 ✔️

Exam Tips & Tricks 📝

  • Every transaction must keep the equation balanced – if one side changes, the other side must change too.
  • Remember: Debit increases assets and decreases liabilities/equity; Credit does the opposite.
  • Use the “double‑entry” rule: every transaction affects at least two accounts.
  • When in doubt, write the equation on a scratch paper and check the totals before finalising the entry.
  • Practice with quick scenarios – the more you rehearse, the faster you’ll spot the correct debits and credits.

Quick Quiz – Test Your Understanding

If a business buys inventory worth $200 on credit, what happens to the accounting equation? Write the new totals for Assets, Liabilities, and Equity.

Answer: Assets +$200 (inventory), Liabilities +$200 (accounts payable), Equity unchanged.
