昇給したって英語でなんて言うの？

An increase in salary is known as a 'raise'.
You can also say:
I've been promoted.
A promotion normally means a raise in salary as well as position.

I hope that helps!

1. To get a raise/rise = "an increase in amount or value" is from 1728. Meaning "increase in salary or wages" is from 1898, chiefly American English (British preferring 'rise').
   "How can Brian afford to go to mexico on holiday?"
   "Oh, he just got a rise."
2. To agree an increase in... = after negotiating, to settle for a higher level off something.
   "My company agreed an increase in my paid holiday entitlement. I now get 4 weeks paid holiday a year."

"Raise" means that your salary has/was increased.

"I got a raise, today!"
"I got a salary increase."
"My salary was put up, I hope, the bonus increases as well.

example
"I got a pay rise, I hope they increase my bonus too".
or
"Good news, my salary was increased".
or
"Yey, my pay went up, I hope they put up my bonus too!".

A salary increase: literally that ;-D "I got a raise" is the go to phrase...but it is mainly for blue collar workers....A lawyer or a doctor would use ..."salary Increase"
:It was really unexpected but I recently got a salary increase."

I got a raise= This is a straightforward easy way to express that your salary increased.

I got an increase in salary= Another very simple way to say that you are being payed more money thank before.
