I posted an updated Wharton acceptance rate analysis which is more accurate than this article. It shows how GPA and GMAT affect your odds of admissions.
When applying to a top MBA program, GMAT and GPA are important parts of the application. As one would expect from a top MBA program, at Wharton GPA has a large impact on your chances of admission. The question is how much does your undergraduate GPA affect your chance of admission. I analyzed the acceptance data from the past two and half years at GMAT Club to see how much GPA impacts acceptance rate. Unlike Harvard where there is little benefit from GPA until 3.8 or higher, at Wharton the acceptance rate generally increases as the undergraduate GPA rises.
At Wharton GPA Increases Chance of Admission
You can clearly see that acceptance rate is lowest below 3.0 and highest in the 3.8 to 4.0 range. There is a slight dip in the 3.6 to 3.79 GPA range. I took a closer look and it appears to be because more applicants in this GPA range worked in industries that Wharton does not value. There are more applicants in the 3.6 to 3.79 range that work in Government and Mutual Funds and fewer in Military and Venture Capital, which are industries that Wharton seems to prefer.
Higher GPA does appear to increase the chance of an applicant being admitted to Wharton, but the slope is not as steep as I would have expected. Unfortunately for some, GPA is stuck in stone. Applicants who hope to increase their chance of admissions need to focus on GMAT to increase their odds. Luckily, data suggests that very high GMAT scores significantly increase the odds that Wharton will accept an applicant. If an applicant studies hard for the GMAT, then a high GMAT score is highly likely achievable. There are many companies that offer GMAT preparation which will increase your chance of admission.
Wharton does not publish statistics on GPA for us to analyze. However, we can look at what the average GPA is in my data set. The mean GPA for accepts at Wharton in my dataset is 3.61 GPA with a middle 80% GPA in the range of 3.23 to 3.94. The mean Wharton GPA of 3.61 is lower than the mean Harvard GPA of 3.66.
