Dawn and Mildred had the same starting sum of $120,000. Each made withdrawals of $24,000 a year. In years 2, 3, and 4, each had returns of 9% a year. Dawn had a 50% drop in year 1 and a 50% gain in year 5, while Mildred had a 50% gain in year 1 and a 50% drop in year 5.
A) Calculate the remaining sum for each woman at the end of year 5.
B) Explain why there is such a big difference in the remaining amounts.
Answer: Initial Investment : $120,000
Cash flow for Dawn :
Year 0 : $120,000
50% drop in first year and 9% growth in 2,3 and 4 years
Year 1 : 120000(1-0.5) - $24000 = $36000
Year 2 : 36000*(1+0.09) -$24000 = $15240
Year 3 : 15240*(1+0.09) -$24000 = -$7,388.4
So Dawn wont have money left to withdraw after year 3
Cash flow for Mildred :
Year 0 : $120,000
50% gain in first year and 9% growth in 2,3 and 4 years
Year 1 : 120000(1+0.5) - $24000 = $156000
Year 2 : 156000*(1+0.09) -$24000 = $146,040
Year 3 : 146,040*(1+0.09) -$24000 = $135183.6
Year 4: 135183.6 *(1+0.09) - $24000 = $123350.1
50% drop in 5th year
Year 5 : 123,350.1 (1-0.5) -$24000 = $37,675.06
Remaining Sum for Mildred at the end of 5th year = $37,675.06
Answer B: It shows the power of compounding, Dawn because of initial drop doesn't have much money to compound and grow on the other hand Mildred because of gain have sufficient amount to grow (compound) and take out $24000 as well from that.
