I think this is mostly a US thing. Why use yearly salary? You’re not paid once a year, are you? Most likely once a month. Referencing monthly salary makes much more sense.
“I’m making 50k”. Great, now I have to guess - dollars? Monthly? Yearly? If yearly then what’s the monthly paycheck? Net? Gross?
I know people who make 50k per month and don’t have jets. I make 30k p/m but I’ll get there one day. It’s crazy how when I was broke making $20/hour in a cafe that I thought everyone or most people are broke but now I’m making modest money it’s crazy how many other entrepreneurs are in my circle now. Just wow.
