That would hit me pretty damn hard. My monthly expenses are exceed whatever 50k is monthly. I'd have to move, probably turn in my car and get a vastly cheaper car or used car, completely cancel auxiliary entertainment stuff, and make cuts to the quality of food I buy.
I'd be devastated quite probably.
Edit: Forgot the most important part. I would have to leave immediately.
Just to further expand...
My rent is currently about 1800.
Car is about 600.
That alone is 2400. 50k between 12 is roughly 4166 a month and this is just gross. Let's say that with all deductions it goes down to 3700. Is have about 1300. Not impossible to live off that, but then factor in expanses like my student loan which is only 100 bucks or so, credit card debt is more than ok let's say about 100 extra a month. My phone bill is about 270 with ATT, 90 for Fiber internet. That's another 360 down the drain. I'd have about 600 left over for groceries and other expenses.
It's doable of course but definitely an impact to my quality of life.
