I think we can all agree that we want a higher GMAT score as it ultimately translates to financial benefits. A 650 can get you into a decent MBA program, but a 700 can get you into a very good program, and a 750 can get you a lot of scholarship money at a very good program and a spot at a top program, assuming the rest of your application is on par. Let's say the difference between a 750 and a 700 is 100k in scholarship money, can we conclude that the value of a 10-point GMAT score increase is approximately 20k? This is being conservative since if the candidate decides to take a spot at HBS over 100k in scholarship money, that can imply that the value of the score difference is over 100k.
I think the difference between a 650 and a 700 is also about 100k, if we are comparing scholarships at decent schools.
Kind of the same for 600 vs 650, at lower-tiered schools.
Let's not argue whether a 750 is actually better than a 700.
All else being equal, an application with a 750 score is at an advantage over one with a 700. The advantage diminishes in the 760+ range though.
So can we estimate that the average value of a 10-point increase in GMAT score translates to about 20k dollars? At least in the 600-750 range. If you wonder whether the implication that a 150 point increase translates to $300k sounds far-fetched, keep in mind that the advantage in starting salary of a graduate of Harvard wipes out the initial financial deficit in about 6 years, on average.
Is this estimate too high, too low, or just about right? Any thoughts are welcome.
