Why your deposit is a debit in your books and a credit at the bank.

The moment it stops making sense

You counted Sunday's offering, took it to the bank, and recorded it. A few weeks later the statement arrives, you look at that same deposit, and the bank has it under a column marked Credit. But when you open your own records, the same deposit is sitting under Debit.

It is a genuinely disorienting moment, and the natural conclusion is that one of them is backwards and it is probably your fault. Neither is backwards. Nobody made a mistake. This one confusion accounts for a large share of why church volunteers decide bookkeeping is not for them, and it takes about four minutes to clear up.

Debit and credit are directions, not judgments

The first thing to unlearn: debit does not mean bad and credit does not mean good. They are not plus and minus either. They are closer to left and right.

Bookkeepers have been writing two-sided entries since before the printing press, and the reason has nothing to do with money being good or bad. It is a checking mechanism. Every event gets written down twice, once on the left and once on the right, and the two sides must come to the same total. If they do not, something was written down wrong, and you find out that week rather than a year later.

Debit is simply the name of the left side. Credit is the name of the right side. That is nearly all the vocabulary carries, and everything else is convention about which side a particular kind of account grows on.

In your books, cash grows on the debit side

For the one account a church treasurer looks at most (the checking account), the rule is short enough to memorize and never look up again:

• Money into the checking account is a debit.
• Money out of the checking account is a credit.

So why does the bank say the opposite?

Because the bank is not keeping your books. It is keeping its own, and it is sitting on the other side of the table.

When you deposit five hundred dollars, that money becomes something the bank owes you. You can walk in tomorrow and ask for it back. On the bank's records that is a debt (a promise to pay you), and a promise growing larger is a credit on their side. So the bank writes your deposit as a credit, and it is telling the truth about its own position.

It is the same handshake, described by two people, each from where they are standing. If you lend a friend twenty dollars, you would write down "lent" and they would write down "borrowed." Nobody would call either version a mistake. A bank statement is your account as the bank experiences it, which is exactly upside down from how you experience it.

Once you have seen that, the statement stops fighting you. Their credit column is your money coming in. Their debit column is your money going out. Same money, opposite ends of the same handshake.

You are not going to be doing this in your head

Here is the part that should take the pressure off, and it is worth saying before anyone goes looking for a cheat sheet to memorize.

Modern accounting software writes both sides of the entry for you. You describe what happened in ordinary words — a gift came in, a bill was paid, a volunteer needs paying back for craft supplies — and the software works out which account gets the left side and which gets the right, and checks that they match.

A volunteer treasurer's actual job is to describe real events accurately and on time. It is not to perform double-entry bookkeeping from memory. Understanding debits and credits is useful the way understanding what a carburetor does is useful (it makes the dashboard make sense), and it is not a thing you should be doing by hand.

The three things worth actually remembering

If you keep nothing else from this page, keep these:

• Debit and credit are left and right, not good and bad.
• In your books, money into checking is a debit; money out is a credit.
• The bank's statement says the opposite because the bank is describing its own position, not yours.
