Went from E4 to E5 in the USAF, that was a big of a raise. Base pay and BAH allowance got some nice jumps. Took a 50% pay cut when I separated, then a 20% pay raise when I started my new job back in April. Got a raise with them after two months, because of how their 'cycles' work. A 7 cent raise because of the proration.
$20,000 raise.
Followed by a $75,000 pay drop a few years later (upon moving to FL)
