Average salary increase for promotion for Non-FO

Long time lurker, first time poster in here.

I know this site is heavily focused on front office positions, but I was curious if anyone knows the typical salary percentage for a promotion for a non-FO job?

I'm currently in analyst in the legal/compliance area of our firm. Assuming I stay at this firm and can get a promotion, what exactly am I looking at in terms of a pay increase? (Not that I plan on being promoted anytime soon, I've only been at this firm for a few months)

Thanks in advance and sorry if this isn't the correct forum.
