That's kind of a hard question to answer. You would have to go to every single website and look at whichever school interests you the most.
A financial engineering program will want to see a math score in the 90th percentile, and above the 80th percentile in the verbal.
A financial management program will want something more balanced, usually above 670.
This is for good to excellent master's program.
But again it depends of what schools you are applying to.
LSE for example wants a minimum of 650 on your GMAT before you consider applying for their MSc in Finance and Accounting.
Oxford engineering one wants 720. The range is huge, so as an average I would say 670.
I had a dream, it involved me getting 510 on my GMAT...
