We will attempt to calculate IRR for a would-be pediatrician
using the following basic assumption. At age 22, the future
pediatrician would start her 4 years of medical school, costing her
$50,309/year. She would then complete 3 years of residency, during
which she would earn an income of $60,094/year. Her salary as a
pediatrician after her residency would be $181,000/year and she
would work until age 65. For simplicity, we assume alternatively,
she would go straight to find a job paying her $45,478/year
starting age 22 if she did not pursue her pediatrician career, and
she would work until age 65 as well.
- Verify that the IRR would be 17.77% by calculating that the
present value of her investment and return over her opportunity
cost would be zero at this rate.
- Now suppose the government want to lower the burden by
providing student loans with zero interest rate to medical
students. For simplicity, let us assume that the effect of such a
policy means she would not incur any tuition costs during her
medical schooling years. Instead, she needs to settle the total
amount of 4 year’s tuition of $201,236 (= 4 x $50,309) at age 48.
Verify that her IRR would now become 27.11%.
