Now, let's do a comparision, assume your cost of capital is $8\%,$ you have $20$ years until retirement $($including any years in school$),$ your current salary is $$60,000$ and you receive a $25\%$ raise whether you complete your MBA, regardless of whether it is the full time MBA program $($taking $2$ years off$)$ or complete it part$-$time over $4$ years while working. What is the best economic decision?
