1)
Account value accumulated in 4 years = Invested Amount * (1 + interest rate)no of periods
Account value accumulated in 4 years = $5100 * (1 + 11%)4
Account value accumulated in 4 years = $7742.16
Account value accumulated in 8 years = Invested Amount * (1 + interest rate)no of periods
Account value accumulated in 8 years = $5100 * (1 + 11%)8
Account value accumulated in 8 years = $11,753.14
Account value accumulated in 12 years = Invested Amount * (1 + interest rate)no of periods
Account value accumulated in 12 years = $5100 * (1 + 11%)12
Account value accumulated in 12 years = $17,842.10
2)
Value of ordinary annuity = Annuity / (1 + interest rate)period+ ,,,,,+ Annuity / (1 + interest rate)period
Value of ordinary annuity = Annuity * (1 - (1 + interest rate)-no of periods) / interest rate
Value of ordinary annuity = $500 * (1 - (1 + 9%)-10) / 9%
Value of ordinary annuity = $3208.83
Value of annuity due = Annuity + Annuity / (1 + interest rate)period+ ,,,,,+ Annuity / (1 + interest rate)period
Value of annuity due = Annuity + Annuity * (1 - (1 + interest rate)-no of periods) / interest rate
Value of annuity due = $500 + $500 * (1 - (1 + 9%)-9) / 9%
Value of annuity due = $3497.62
Annuity due is a better investment since the value of the money received today is more than the value received in the future. Annuity due makes payments at the beginning of the year while the ordinary annuity makes payments at the end of each year. The discounting periods for Annuity due are lower than ordinary annuity.
