I do this. Sometimes I add the info the same day, or just do it all on the weekend. Probably takes 10 minutes a week. I can then take that info and compare to any budgets or predictions and see where things are going right or wrong.

I’ve had everything balance down to the penny for 20 years now. If you have some attention to detail and make it a habit, it’s not really that difficult or time consuming.

It’s also kind of like paying cash. It makes you more aware of what you are spending.
