What is the Accounting Equation

The accounting equation is the foundation of all double entry accounting systems. It explains the relationship between what a business owns, what it owes, and the owner’s stake in the business.

What is the Accounting Equation?

The accounting equation is:

Assets = Liabilities + Equity

This formula represents the financial position of a business. It ensures that the company’s books are always balanced, which is essential for accurate financial reporting.

Assets: What the business owns.
Liabilities: What the business owes to others.
Equity: The owner’s claim on the business’s assets after all liabilities are paid.

Every transaction a business makes affects at least two accounts and keeps this equation in balance. 🧾

Components of the Accounting Equation

1. Assets 💰

Assets are the resources a business owns that have value. They can be used to generate revenue or help the business operate. Assets are categorized into two main types:

Current Assets: These are assets that can be converted into cash within a year, such as cash, Inventory, etc.
Non-Current Assets: These are long-term investments or resources that cannot be quickly converted to cash such as equipment, machinery, property, etc.

2. Liabilities 📉

Liabilities are what the business owes to others. These are obligations that must be paid back in the future. Like assets, liabilities are categorized into:

Current Liabilities: Debts or obligations due within a year. Such as, payables, overdrafts, etc.
Non-Current Liabilities: Debts or obligations due over a longer period, such as loans.

3. Equity 📈

Equity represents the owner’s share of the business. It’s what remains after liabilities are subtracted from assets. Equity includes:

Capital: Money invested by the owner(s) into the business.
Retained Earnings: Profits that are reinvested into the business rather than distributed as dividends.

Since Accounting is a an equation, like all equations we can move things from one side of the equation to the other. So to find equity, we simply move over the liabilities so it is subtracted from the Assets, like so:

Equity = Assets – Liabilities OR Assets – Liabilities = Equity

How the Accounting Equation Works

The accounting equation ensures that every financial transaction maintains balance. Let’s look at some examples to understand how it works in practice. 🔍

Example 1: Starting a Business

Imagine you start a business with $10,000 in cash. The accounting equation looks like this:

Assets: $10,000 (cash)
Liabilities: $0
Equity: $10,000 (owner’s investment)

The equation balances:

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

Example 2: Taking a Loan

You take a $5,000 loan to buy equipment. Here’s how the equation changes:

Assets: $15,000 ($10,000 cash + $5,000 equipment)
Liabilities: $5,000 (loan)
Equity: $10,000

The equation still balances:

Assets ($15,000) = Liabilities ($5,000) + Equity ($10,000) ✅

Example 3: Earning Revenue

Your business earns $2,000 by selling goods. This increases cash and retained earnings:

Assets: $17,000 ($15,000 + $2,000 cash)
Liabilities: $5,000
Equity: $12,000 ($10,000 capital + $2,000 retained earnings)

The equation balances:

Assets ($17,000) = Liabilities ($5,000) + Equity ($12,000) ✅

Example 4: Paying Expenses

You spend $500 on office rent. This decreases cash and retained earnings:

Assets: $16,500 ($17,000 – $500 cash)
Liabilities: $5,000
Equity: $11,500 ($12,000 – $500 retained earnings)

The equation still balances:

Assets ($16,500) = Liabilities ($5,000) + Equity ($11,500) ✅

Conclusion

The accounting equation is the most essential tool for understanding a business’s financial position. Whether you’re starting a business, tracking earnings, or preparing financial reports, mastering the accounting equation is the first step to financial success.

With practice and careful record-keeping, you’ll find that the accounting equation becomes second nature, helping you maintain balance in every transaction you record.
