As in, I remember that back in my apprentice days I knew how much I got paid per hour.
Now recently I had to look trough my documents to find out what my monthly salary even is because it’s raise season and I have to give my manager a number higher than that so that he can advocate for it to the board of directors.

I still remember my yearly salary semi-accurately (like within 10%), but I bet super rich people either go by decades or don’t know at all what they make in a year.

On the other side, my friends who work retail jobs have a decent estimate of what they make per week or two week span, even if they are paid monthly.
