Can be staying in same job, promotion related, or career change based. Since we have a wide range of people here, let's talk %. What % of your prior salary was the raise? For example, if someone earns $100,000 per year, and gets a raise to $125,000 then their raise was a 25% raise. 
Mine was a 60% raise when I switched from public school teacher to full time graduate professor/ doctoral researcher.
Actually, McDonalds corporate is supposed to be pretty good to work for.
ive had years where my pay went down 40-70%
Biggest was a while ago when I went from a shit job I hated to a job I actually wanted.
I accepted the new job based on a salary figure that was a 21% increase from my shit job. After 3 months of training at the new job, they floored me with a completetly unexpected raise that made it a total improvement of 34% [from the shit job].
I went from $30K to $45K to $69K with 3 different companies in 5 years.
Now Im making shit ....
I'm potentially looking at a promotion at the end of the month which includes a 50% raise. 
Went from making 50k-85k in 2 yrs.
I was making 60k a year my first year out of Highschool. Second year I made 100k for the next 2 years I made 110-120k. Then I quit that job because I was miserable. I made less than 25k for a while now, and now I'm self employed. Don't know how much I'll make this year.
But I've never been happier.
