In my opinion, the only finance job you need to get an MBA for is investment banking. If you just want to do FP&A (which sounds like what you're describing), an MBA doesn't really help you at all. Investment banking is different because the only times you can get hired into investment banking is 1) when you get hired as an analyst after graduating college, 2) when you get hired as an associate after graduating from your MBA, or 3) when you get hired as a senior banker after having been a senior executive with a useful rolodex that can generate revenue for the firm. For most people, #3 is not possible, so if you didn't get hired as a college student, your only chance of breaking in is through a MBA.

The high pay in investment banking also makes it a lot more worthwhile to invest in a MBA education. Instead of the average low six figure salary most MBAs make, you would make $220k+ on average as someone who just finished business school and is starting in investment banking. The ROI is much, much better.

To see what MBA programs are the best for getting into investment banking, you can look at the attached efinancial article.
