WARNING: If you're really struggling with double entry accounting and you've come straight to this page, you might find it a little tricky... The lessons on this site build up step-by-step, so if you haven't reviewed any of the earlier lessons, you may want to do so first.

Start with the previous section on Basic Accounting Transactions. In those lessons you'll go through each type of transaction and gain a thorough understanding of how each transaction affects the basic accounting equation. Revising these earlier lessons should make your ongoing studies much easier.

Be sure to check your understanding of this lesson by taking the quiz in the Test Yourself! section further below. And right at the bottom of the page, you can find more questions on the topic submitted by fellow students.

## What is the Double-Entry System of Accounting?

In one of our first lessons we asked the question, What is Accounting? and learned that it is a system of recording information about a business.

Well, this system has a specific name.

That name is the double entry system of accounting.

Double entry means two entries.

And we literally make two entries - for every single transaction.

Why are there two entries instead of just one?

You may not be surprised by this, but it's all based on our basic accounting equation:

Just like any equation, the basic accounting equation has two sides.

There's assets on the left side. And owners equity + liabilities on the right side.

When a transaction takes place, it doesn't just affect the one side - it usually affects both.

Or, to put it more accurately, a transaction always affects two accounts.

## A Simple Double Entry Accounting Example

Here's a simple example of a double entry to illustrate how this works:

ABC Business takes out a loan of \$50,000 from the bank.

Here is what the double entry, called a journal entry, would look like for this:

I'll explain exactly how I got to this journal entry below.

First, let's look at the transaction and its impact on the accounting equation.

This transaction results in more assets (in the form of cash for the business) and also more liabilities (in the form of the loan).

Now, we could just make a single entry and record that we received more cash.

But where did this cash come from?

If we didn't make any further entry, we'd have to guess later on when we looked at our records. We'd just see a record of receiving \$50,000 cash.

Maybe the \$50,000 cash came from income we made? Or maybe it was additional capital invested by the owner?

We simply wouldn't have a good record of what happened.

So instead of just recording the increase of our cash, we also record a second entry about how the cash came about or where it came from - a loan.

Looking back at our accounting equation above, the left side increases by \$50,000 and the right side also increases by that amount.

The increase to that left side (assets) is one entry.

And the increase to the right side (liabilities) is the second entry.

OR...

The entry to increase bank (or "cash") is one account and one entry.

And the entry to increase loan (a liability) is a second account and a second entry.

## Recording the Journal Entry (Debit and Credit)

The double entries we make have a specific name. You've probably heard of them before. One of these entries is called a debit and the other is called a credit.

Here is the double entry again for the above example:

DR is an abbreviation for the Latin word debere ("to owe") or for "Debit Record."
It indicates a DEBIT ENTRY.

CR is an abbreviation for the Latin word credere ("to entrust to another") or for "Credit Record."
It indicates a CREDIT ENTRY.

The debit to Bank simply indicates that our Bank account is increasing.

And the credit to the Loan account (a liability account) means this is also increasing.

## Moving Forward

For a full, detailed tutorial on how to figure out which account is debited and which is credited for any transaction, see our mind-blowing tutorial Debits and Credits: What They Really Mean.

After that we'll go through each of the transactions we went over previously with our sample business, George's Catering, but this time we'll delve deeper and go over the exact debit and credit entry for each one.

But before all of that, in the 2nd lesson in this section, we're going to take a look at an alternative viewpoint of the basic accounting equation. This short but powerful lesson should provide you with even greater certainty on the accounting equation and give you a better understanding of the two entries in our double entry accounting system.

So, what are you waiting for? Time to get stuck into double entry accounting and the debit and credit entries.
