I was paying my credit card bill on the due date for a decade until my bank statement showed a $45 interest charge last month. | Adulting Hard - Talk Freely
You have my complete sympathy. I did the exact same thing for years with a store card, paying on the due date and never looking at the statement. The interest quietly piled up on a small balance I didn't realize was still there. It's such a common trap because the due date feels like the important deadline. Now I pay as soon as the statement posts to avoid any chance of that cycle starting again.
