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?
Is 50k per year below average in the US? Is it hard to survive on that amount?
If you have a family it’s poverty wage.
To add to the other poster, in the USA we have calculators for these things.
There is lots of info available, but a short answer is:
The real median earnings of all workers aged 15 and over with earnings decreased 1.2 percent between 2019 and 2020 from $42,065 to $41,535
Comparing that to where I live.
The median is about $37k per year.
On the other hand. I make around $13k, single household, studio flat close to the city center and I make do just ok. Wouldn’t hurt to earn a bit more. But on the other hand I work a bit less than 50%. It’s hard to find work though and inflation is making living harder.
It depends significantly on location and living situation, but 50k ranges from moderately comfortable all the way to poverty line.
