or Formula

Previous lesson: Define Accounting

Check out the quiz in the Test Yourself! section further below when you're done with this lesson. And right at the bottom of the page, more questions on the topic submitted by fellow students.

Have you heard of the basic accounting equation or accounting formula?

Do you know what it is?

It's the fundamental equation that underpins all of accounting.

In other words, it's really important.

Why is it so important?

Because all accounting entries - all of them - are derived from it.

Let me say that again: All accounting entries. All of them.

So, if you really understand this equation, the rest of accounting becomes that much easier.

If you don't understand it, you'll probably find the subject very hard.

No pressure, right?

Okay, so pay attention...

The whole of accounting is based on one single equation: 


Accounting = Balance double entry system

The word equation comes from the word equal.

For any equation, one side always equals another.

Also, equations can actually be made out of anything.

For example:

  • 1 Orange = $0,50
  • House = Walls + Doors + Windows + Roof
  • 1 week = 7 days

So what does the basic accounting equation or basic accounting formula mean?

Well, in order to answer that question we need to look at what each of the terms in the equation mean.


accounting asset example - construction Vehicle

Assets are basically possessions of the business. They are things that add value to the business and will bring it benefits in some form.

For example, furniture, machinery, vehicles, computers, stationery or cash.

liability example - bank loan debt

Liabilities are basically debts.

The amount of liabilities represents the value of the business assets that are owed to others. It is the value of the assets that people outside the business can lay claim to.

Owners Equity (or Equity)

Owners equity, or simply, equity, is the value of the business assets that the owner can lay claim to.

It is the value of the assets that the owner really owns.

What the Basic Accounting Equation Means

In a nutshell, the accounting equation above shows us:

  • How much of the assets are owed to others (liabilities), and
  • How much are owned by the owner (equity).

It's as simple as that.
