Let's start with a review of the general journal. The general journal is the original book of entry. It contains the transaction detail for accounting events in a chronological order.
Journal entries are specific changes to accounts--meaning the debits and credits. Journal entries derive their name from their use within the general journal. Referring back to the accounting cycle, you may recall that it starts with analysis, so if you perform your analysis and determine that there is an accounting event, the next step would be to journalize the transaction. It's important to remember that there are no journal entries until accounting events have taken place.
Let's explore some examples of creating journal entries.
Well, you know that you're going to have equipment. You're purchasing an asset, so your assets are going up. Remember, the reference number is from your chart of accounts, so in this case, account number 3001 shows a debit of $10,000.
You must also reflect at least one credit. In this case, you are paying cash, so you must show a credit to your cash account of $10,000. Now you have your journal entry within your general journal for this transaction.
You know that you're purchasing equipment, so your equipment's going up with a $10,000 debit.
However, to what account is your credit going to be? It's not cash in this case. Since it's on account, it's going to be accounts payable. It's a liability, or money that is owed, and liabilities are increased with credits. Therefore, you have a $10,000 debit to equipment and a $10,000 credit to accounts payable. It is important to note that the unique identifier for a journal entry here is J102. That unique identifier changes with each transaction that you are adding to your general journal.
Well, if you're paying down a liability, that must mean you have to debit your accounts payable.
In addition, if you're paying cash for that, it means that your cash is also going down. Therefore, you have a credit to cash of $5,000.
Similar to the last entry that you made, it involves accounts payable. You are paying off your entire balance, so you're paying all $10,000. Again, the liabilities are reduced by debits, so there is a $10,000 debit to accounts payable.
You also must have a credit to cash, because you are paying cash. Therefore assets--because cash is an asset--are reduced by credits, so you have a credit to cash of $10,000.
Owner's draws are a reduction of equity; because the owner is pulling cash out, his or her equity is going down. This is recorded with a $2,000 debit within the journal entry.
Regarding the credit, if he or she is taking cash out, that must mean cash is going down. Assets are reduced by credits, so there is a $2,000 credit to the cash account.
You know if you're receiving cash, that must mean your assets are going up. Therefore, you would debit your cash account.
However, what do you think the credit is to? It is for future services that haven't been performed yet, so it wouldn't be revenue. It would be unearned revenue. Therefore, it is a liability, because you haven't performed those services yet, but you have an obligation to perform them because you've been paid. Since liabilities are increased with credits, there is a credit to your unearned revenue.
You are pre-paying the expense, which is an asset. It gets recorded with a $1,000 debit in your journal entry within our general journal.
What about your offsetting credit? You paid $1,000 cash, which must mean that your cash is going down. Therefore, you would credit cash for $1,000.
