In general, you can expect your base offer to run from $145K-$148K, though McKinsey heads the leading consulting firms by offering $152K to start. When it comes to performance bonus, McKinsey is middle of the pack, with Strategy& consultants able to max out at $47K in bonus. Like base pay, MBAs generally collect the same signing bonus as everyone else -- $25K -- though KPMG and BCG offer a bit more to onboard top graduates.
