Is an Economics minor supplementing a math major worth an extra semester?

I’m a senior math major who’s able to graduate Summer 2017 with a B.S. in Mathematics with a concentration in Finance. By that point, I will have all but one class completed for an economics minor. Would it be worth it staying the extra semester and graduating in the fall of 2017 with the minor or just the math major?

I do plan on getting a master’s degree directly after my B.S. This master’s will either be in math, finance or computer science.

I’d talk to an advisor about it. Personally, I wouldn’t want to pay an extra semester worth of costs just to get a minor if I was getting a grad degree anyway. An advisor could probably give you a better perspective than me though
