Question

An engineer who is now 65 years old began planning for retirement 40 years ago. At that time, he thought that if he had $1 million when he retired, he would have more than enough money to live his remaining life in luxury. Assume the inflation rate over the 40-year time period averaged a constant 4.7% per year.

a) What is the CV purchasing power of his $1 million at age 65? (Hint: Use the day he started 40 years ago as the base year.)

The CV purchasing power is $  .

b) How many future dollars should he have accumulated over the 40 years to have a CV purchasing power equal to $1.9 million at his current age of 65?

To have a CV purchasing power of $1.9 million, he should have accumulated $  future dollars.

Explanation / Answer

a.

CV purchasing power 40 year before = $1,000,000 / (1 + 4.70%) ^ 40

= $1,000,000 / 6.2787

= $159,269.54

CV purchasing power 40 year before that is day he started 40 years ago as the base year was $159,269.54.

2.

CV purchasing power = $1.9 million

Future accumulated value = $1,900,000 × (1 + 4.70%) ^ 40

= $1,900,000 × 6.2787

= $11,929,462.27

Future accumulated value will be $11,929,462.27.
