Answer:
Winning a lottery,
a) Lump sum option = $600,000;
b) Yearly option = $772,173.49
Not winning a lottery,
Grand savings will be = $86,322.50
Step-by-step explanation:
Requirement 1) Winning a Lottery -
a) If I take the lump sum option, I will get the tax-deducted amount. Since the tax rate is 40%, I will get -
= $1,000,000 x (1 - 0.40)
= $1,000,000 x 0.60
= $600,000
b) If I choose the second option, I might get -
PV = PMT x [{1 - (1+r)^(-n)}/r]
PV = $100,000 x [{1 - (1+0.05)^(-10)}/0.05]
PV = $100,000 x 7.7217
PV = $772,173.49
From the above calculation, I will accept the yearly payment as it provides more earnings than the lump sum amount.
Requirement 2) Not Winning a Lottery -
Every day earnings = $5
Yearly earnings = $5 x 365 = $1,825
If I retire at the age of 65 years, therefore, I will save for (65 - 22) = 43 years.
Therefore, the savings will be = 43 x $1,825 = $78,475
If the savings for the average interest rate 10%, the total will be =
$78,475 x (1 + 0.10) = $86,322.50
Therefore, I will have $86,322.50 when I retire at age 65.
Requirement 3) If I started this plan later in my life, I would lose savings for how many years I wait for the started savings. For example, If I began at the age of 30, I would lose eight years of savings. Therefore, I would lose 7*$1,825 = $12,775 savings. I would also lose the grand savings of $12,775 x (1 + 0.10) = $14,052.50.
Therefore, for each year's of delay would lose $1,825.00 amounts.
