How much is an MBA worth?

Assume that you were earning $40,000/year before entering 2-year full time MBA program and that tuition costs are $16,000/year. Expected salary is $54,000/year after graduation. You can invest money at 8%.

Assume that you will work 30 years after graduation, and that the salary differential ($14,000 = $54,000- $40,000) will continue through this period.

For simplicity, assume that the first payment of $16,000 has to be made at the start of the program and the second payment one year later.
