What exactly does it mean to “debit” and “credit” an account? Why is it that debiting some accounts makes them go up, but debiting other accounts makes them go down? And why is any of this important for your business?
Here’s everything you need to know.
What is a debit?
In double-entry accounting, debits (dr) record all of the money flowing into an account. So, if your business were to take out a $5,000 small business loan, the cash you receive from that loan would be recorded as a debit in your cash, or assets, account.
What is a credit?
Credits (cr) record money that flows out of an account. To use that same example from above, if you received that $5,000 loan, you would record a credit of $5,000 in your liabilities account.
What types of entry methods are there for recording transactions?
There are two methods of recording transactions in accounting: single-entry and double-entry.
Because single-entry bookkeeping is a cash system, which simply records incoming and outgoing cash in a single ledger, it’s not used very often by professional accountants or bookkeepers.
Most accountants, bookkeepers, and accounting software platforms use the double-entry method for their accounting. Under this system, your entire business is organized into individual accounts. Think of these as individual buckets full of money representing each aspect of your company.
For example:
- One bucket might represent all of the cash you have in your business bank account (the “cash” bucket)
- Another bucket might represent the total value of all the furniture your business has in its office (the “furniture” bucket)
- Another bucket might represent a bank loan you recently took out (the “bank loan” bucket)
When your business does anything—buy furniture, take out a loan, spend money on research and development—the amount of money in the buckets changes.
Recording what happens to each of these buckets using full English sentences would be tedious, so we need a shorthand. That’s where debits and credits come in.
When money flows into a bucket, we record that as a debit (sometimes accountants will abbreviate this to just “dr.”)
For example, if you deposited $300 in cash into your business bank account:
An accountant would say we are “debiting” the cash bucket by $300, and would enter the following line into your accounting system.
When money flows out of a bucket, we record that as a credit (sometimes accountants will abbreviate this to just “cr.”)
For example, if you withdrew $600 in cash from your business bank account:
An accountant would say you are “crediting” the cash bucket by $600.
Debits and credits in action
There’s one thing missing from the examples above. Money doesn’t just disappear or appear out of nowhere. It has to come from somewhere, and go somewhere.
That’s what credits and debits let you see: where your money is going, and where it’s coming from.
Let’s say that one day, you visit your friend’s startup. After taking a tour of the office, your friend shows you a beautiful ergonomic standing desk. You’ve been looking for this model for months, but all the furniture stores are sold out. Your friend ordered an extra one, and she can sell it to you for cheap. You agree to buy it from her for $600.
Here’s what that would look like using our bucket system. First, we move $600 out of your cash bucket.
Just like in the above section, we credit your cash account, because money is flowing out of it.
But this isn’t the only bucket that changes. Your “furniture” bucket, which represents the total value of all the furniture your company owns, also changes.
In this case, it increases by $600 (the value of the chair).
You debit your furniture account, because value is flowing into it (a desk).
In double-entry accounting, every debit (inflow) always has a corresponding credit (outflow). So we record them together in one entry.
An accountant would say that we are crediting the bank account $600 and debiting the furniture account $600.
How debits and credits affect liability accounts
The two buckets we used in the above example—cash and furniture—are both asset buckets. (That is, they keep track of something you own.)
But not all buckets are asset buckets. Some buckets keep track of what you owe (liabilities), and other buckets keep track of the total value of your business (equity).
Let’s imagine that after buying that expensive desk, you want to get some extra cash for your business. So you take out a $1,000 bank loan, and you increase (debit) your cash account by $1,000.
Now here’s the tricky part.
In addition to adding $1,000 to your cash bucket, we would also have to increase your “bank loan” bucket by $1,000.
Why? Because your “bank loan bucket” measures not how much you have, but how much you owe. The more you owe, the larger the value in the bank loan bucket is going to be.
In this case, we’re crediting a bucket, but the value of the bucket is increasing. That’s because the bucket keeps track of a debt, and the debt is going up in this case.
How debits and credits affect equity accounts
Let’s do one more example, this time involving an equity account.
Let’s say your mom invests $1,000 of her own cash into your company. Using our bucket system, your transaction would look like the following.
First, your cash account would go up by $1,000, because you now have $1,000 more from mom.
But that’s not the only bucket that changes. You mom now has a $1,000 equity stake in your business—so the bucket labelled “equity (Mom)” also increases by $1,000:
Why is it that crediting an equity account makes it go up, rather than down? That’s because equity accounts don’t measure how much your business has. Rather, they measure all of the claims that investors have against your business.
The Equity (Mom) bucket keeps track of your Mom’s claims against your business. That’s her equity, not your business’s. In this case, those claims have increased, which means the number inside the bucket increases.
Debits and credits chart
Most people will use a list of accounts so they know how to record debits and credits properly. And if that’s too much to remember, just remember the words of accountant Charles E. Sprague:
“Debit all that comes in and credit all that goes out.”
