I noticed that at US Bank some 30 years ago. My checking balance was always a few cents less than what my checkbook said I should have. It would be random like -.37, -.66, -.43, but always negative.
I switched to a small local bank and my accounts have been correct to the penny for 30 years.
I always wondered whose account all those pennies from who knows how many accounts they were going into.
Paying bills has never been easier with auto-draft, online payments, Venmo, etc. It’s easy to let bills slide for a couple of months without logging everything into the Excel spreadsheet. The one thing I demand of myself is staying on top of the two checking accts we have. And, I do it the old fashioned way...the bank statement compared to the ledger, calculated on a 9-key...to the penny.
I doubt my kids have ever balanced a checkbook.
