Answer:
a) Amount to be invested today = $506,830.9
b) She will retire in 10.5 years time
Explanation:
The amount to be invested by Sara Wiggum today at 4% to accumulate $2 million in 35 years is called the Present Value.
Present value (PV) is the discounted value of a future amount at the opportunity cost rate of return . The amount to be invested now at a particular rate of return to equal a future sum.
Present Value (PV)= (1+r)^(-n) × Future cash flow
For Sarah, the
PV = (1+0.04)× (-35) × 2,000,000
= 0.2534 × 2,000,000
= 506,830.9415
Amount to be invested today = $506,830.9
<em>How soon will She retire at rate of 14% per annum?</em>
The PV is still 506,830.9415,
FV is still 2,000,000,
But rate now is - 14%, and
n - ?.
so we need to work out "n"
Work out "n" as folows:
(1+0.14)^(-n) = 2000000/506,830.9
(1+0.14)^(-n) = 3.9406
n = log 3.9406/log 1.14
n = 10.5 years
She will retire in 10.5 years time
