At the B1G school I worked at in the midwest, most of the major gift officers made between $110-$160k. Annual giving and stewardship officers made less. Law/Business/Med usually made more than, say, the gift officer for the library or ed school. There was no "commission," but if you brought in high dollar gifts, you would be more likely to be promoted or end up at law/bus/med. The benefits and leave policy was amazing. Many of the positions required a lot of travel and were stressful. At the end of the day, it is a sales job...a rewarding sales job, but a sales job.
