University of Kentucky Young Engineer Retirement Questions

Question Description

I’m working on a Engineering exercise and need support.

A young engineer decides to save $240 per year toward retirement in 40 years.

  1. If he invests this sum at the end of every year at 9%, then how much will be accumulated by retirement time?
  2. If by astute investing the interest rate could be raised to 12%, then what sum could be saved?
  3. If he deposits one fourth of this annual amount each quarter ($60 per quarter) in an interest bearing account earning a nominal annual interest rate of 12%, compounded quarterly, how much could be saved by retirement time?
  4. In part (c), then what annual effective interest rate is being earned?
