You currently make $100,000 a year and expect your salary increase by 10% a year for 20 years. You are considering an MBA which will cost you $120,000 for the entire education. If you take the MBA, you will have to pay the full tuition today (all upfront) and you will make zero earnings at the end of years 1 and 2. However, after graduation youll have an opportunity to join an investment bank, which promises $130,000 a year, which will grow by 15% for 18 years after graduation. Is the MBA a good deal?
