What GPA is needed to keep options open?

[Vandy]

I'm a CS sophomore at Vanderbilt.  I'm not sure if I will want to pursue grad school in the future,but I want to keep my options open.  What GPA is generally expected in order to be a competitive applicant for masters or even phd programs?  Thanks in advance.

The higher the better. Aim for 3.7 or higher for top programs. You can get into the unranked programs with a 3.0 GPA, but who wants to aim for mediocrity?

3.2-3.3 is fine for Master's for schools ranked around Vandy's ranking. For schools a bit higher, 3.5+ is good. For the Stanford's, 3.8+.

For PhD, try to get 3.6+ (or 3.8+ for the Stanford's) and get plenty of research experience and great letters.
