For an asset account, I've learned that debit increases the balance. This makes perfect sense.
So that it's straightforward to calculate net worth, it would make sense that when I buy something on a credit card, that would be a decrease (which is still a debit since it's a liability account). So am I right in saying that despite it being the normal state of affairs for a credit card account to be in the red, that it should still be displayed with a negative balance?
This is to do with a hobby software project I'm working on that includes a (hopefully powerful but simple) accounting module.
Many thanks in advance.
