I do free basic personal money management instruction to friends and acquaintances,, and one thing we do early on is try to simplify as much as possible all the accounts that a person has. I myself have just 8 active accounts (Schwab brokerage/IRA/solo checking/joint checking, Chase Sapphire solo CC, Southwest Visa joint CC, Venmo, PayPal) with just five logins, and I made it that way on purpose. I know some accounts are not within a person's control (the enterprise 401k is going to be wherever it is, etc) but I see people here trying to deal with four or five times as many accounts, which I imagine could be overwhelming.
Now I don't handle my wife's personal accounts so that would be a couple more, and we have no kids (just recently married, middle aged, so we each already had our own money and merely created a joint checking and joint CC for paying the bills) so I realize that one person doing ALL of a family's finances could certainly add some accounts.
Anyway, I was just curious because as I said, when sitting down with a new person I'm trying to help, the first discussion is usually figuring out how we can simplify where their money is going to and from. I've seen some crazy things!
