Finance (hedge funds, investment banks, and private equity) jobs can have bonuses that are several multiples of the base pay, especially at the higher levels.
The only job where I've ever gotten more than a token bonus was when I worked at an investment bank. For us in IT and other "support" departments it was in the range of 10 - 20% of base; the actual financial guys got much more.
Manager's compensation is mostly bonus-based the higher you go, in the guise of "hitting your yearly targets." Senior Mgr is about 10% to 25% of base salary. Director is about 15% to 40%. VP is certainly 30% to 80%. CEO might solely depend on bonus to get the big windfall, like stock price hitting certain level.
