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 mean surely it’s obvious in that example, no?
If that’s the native currency wherever you are, then of course dollars
$50k/month about be $600k/year. Pretty sure you’d be able to tell if the person you’re talking to made half a million dollars a year vs just above the poverty line (in the US at least) just from context, but when in doubt - it’s probably safe to assume that the person you’re talking to isnt in the top 1% of earners
Yearly divided by 12? If you’re in a hurry and want a rough estimate just chop a number off the right and that’ll get you to within ~10% of the correct value
I’ve literally never heard anyone give their salary as gross outside the context of financial planning, and even then they’ll always specify “after taxes” or something similar.
Other comments go into plenty of detail about why they se various conventions are what they are (yearly vs monthly, net vs gross, etc(
