We can go nuts accounting for the budgets and expenses. Frankly it is needed for the people who have no idea where their money is going, says Moneysense. Meanwhile, my partner (Sanaa) and I did it during my PhD years out of dire need. Now, we do it to stay on top of our expenses. However, it burns too many cycles. I think once the expenses are figured out then there is no need for "nit picking". Ball park budgeting is fine. Only need to pay attention when the expenses are "out of whack" compared to the budget. Similar sentiments are voiced by MoneySense Nov 2016 issue.
