Casey is right, when you look at your bank statement, the statement is shown from the perspective of the Bank. The money you deposit is a liability to the bank, therefore when you withdraw money their Liability is reducing hence a debit.

From the companies perspective, cash/bank a/c are an asset, hence the rule applies, i.e., 'An entry which increases an asset account is called a debit.' For example when you by a machinery for cash following transactions occur:

Debit: Machinery A/C ( Asset increasing, hence the Debit)
Credit: Cash/bank A/C (ASSET decreasing, hence the Credit)

Hope this helps!

Spongebob, you need to have an understanding of how the accounts interact. When in doubt: A = L + O.E.

Think of Assets as the property of the business. How did you pay for them? Through either 1) Debt (Liability) or 2) Your own money (O.E).

Forget the example of your bank. That confused me when I was first learning accounting too. Just look at the statement

A=L+O.E
If A went up then L or O.E must have as well.
If A goes down then L or O.E must too.
