Lifestyle creep refers to a phenomenon where an increase in income leads to an increase in nonessential expenses (things you
don't really need).
When this happens, things that used to be luxuries become your new normal, you perceive them was if there essentials.
This phenomenon can start a loop:
You get a raise, so you have extra
money.
You have extra
money, so you spend more
money.
You spend more money, so you live check to check.
You live check to check, so you work harder.
You work harder, so you get a raise.
Person A: I just got this
huge raise, any ideas on what to spend it?
Person B: I think you should save it, lifestyle creep is easier to prevent than to
stop.
