John,I am a recruiter who specialises in taking people out of IB and placing them in consultancies. On the whole for people with 3-8 years experience, I have found that IB and Consultancies pay a similar amount in terms of base salaries, the area that there is considerable difference is bonuses, where IB pay significantly more. At the very junior and very senior ends of the spectrum (ie less than 3 years and more than 10 years) IB pay more in terms of base and bonus.However at the senior end of consulting, if you have the ability to sell consulting assignments, Consultancies will pay through the nose to get you.
