With the hefty amount of time you'll have to devote to classes, studying, and related activities, you won't have much time or energy left over for personal, family, or leisure activities. Your MBA is an investment in yourself, and as with any investment, you need to decide whether the potential return is worth the time and money spent. The MBA degree does not guarantee a fabulous job at a fabulous salary. Half of the salaries fall below the average. Salaries are influenced by local conditions.
Salaries tend to be higher in areas with high living costs and lower where it's cheaper to live.
An MBA grad's salary is also influenced by his or her salary profile prior to entering the program. Look at the financial costs and benefits realistically. But your decision to get an MBA may not depend on the bottom line. There are returns beyond financial ones. The degree may give you greater job mobility, access to positions that offer greatly enhanced job satisfaction, or other non-financial advantages.
