I actually dipped into the red on my Maestro a couple of times, but I haven't seen any interest charges hit my account yet. Honestly, those 14% annual interest rates they talk about just confuse me. Like, how does that math even work in practice? Probably a pretty dumb question, but I'm just lost here.
They definitely would have calculated it, but honestly, the amount was probably so tiny you wouldn't have even noticed it on your statement.
The way it works is that they calculate the interest on a daily basis and then just charge you once a month. So, what that means is if you end up overdrawn at the beginning of the month, but you manage to move money back in and clear that negative balance after about a week, they’ll calculate the interest specifically for those seven days you were in the red, and then they'll just tack that total onto your bill at the end of the month.
For example, if you go into the negative $333, that 14% interest rate would mean you're looking at something like maybe 10 or 15 cents a day depending on the amount. If you cleared that balance pretty quickly, you probably didn't even realize those few pennies were being added up...
I’m pretty sure that’s exactly what happened here.
