I don't use a debit card. Everything possible goes on a credit card, which I pay off every month. Anything that can't be put on the card (I don't pay additional fees) gets the autopay treatment from my checking account.
I've got a savings account with a decent interest rate and have not found ACH transactions to be too slow.
So, I keep track of everything in my Excel file, which is why I find a handwritten check ledger so antiquated and incomplete. It doesn't project expenses, doesn't keep track of savings once saved, and only has very limited budgeting capabilities, if any.
I wonder if all the online resources and software available nowadays have led to an increase in financial literacy, come to think of it. Scribbling on paper just seems so error prone, primitive and incomplete.
