EDUCATION COSTS - INVESTOPEDIA https://www.investopedia.com/articles/professionaleducation/09/mba-real-costs.asp

Higher education costs in the United States have outgrown the rate of inflation, and getting an MBA has associated tuition expenses along with rent and book costs. MBAs, especially those who go to private business schools, can accumulate between $100,000 and $200,000 in debt and expenses in just over a two-year period. Fortunately, for those who are highly motivated to secure an MBA, there are alternative options one can explore in order to both receive the degree as well as minimize the costs...

So summing it up, $80,000 for tuition, $40,000 for boarding and books, $20,000 for peripheral expenditures brings the total MBA cost to around $140,000, while the lost income brings the tab to a whopping $260,000. That figure amounts to more than four years of salary at an annualized income rate of $60,000
