Suppose an annuity pays 6% annual interest, compounded semi-annually. You invest in this annuity by contributing $4,500 semiannually for 6 years. What will the annuity be worth after 6 years? Assume that the annuity is compounded with the same frequency as deposits are made unless stated otherwise.

Sagot :

The annuity that should be worth after 6 years is $63,900.

Given that,

  • The present value is $4,500.
  • The semi-annual time period should be = 6 × 2 = 12.
  • The rate of interest on semi-annual basis should be = 6% ÷ 2 = 3%

Now the following formula should be used:

[tex]Amount = Present\ value \times \frac{(1+ rate)^{(n)} - 1} {rate}\\\\= \$4,500 \times \frac{(1+0.03)^{12} - 1}{0.03}\\\\= \$4,500 \times \frac{0.4257}{0.03}\\\\= \$4,500 \times 14.1920\\\\= \$63,864\\\\= \$63,900[/tex]

Therefore we can conclude that the annuity that should be worth after 6 years is $63,900.

Answer: 63900

Step-by-step explanation: Use the savings annuity formula

PN=d((1+r/k)N k−1)r/k

to calculate the value of P6. The question states that r=0.06, d=$4,500, k=2 compounding periods per year, and N=6 years. Substitute these values into the formula results in

P6=$4,500 ((1+0.06/2)6⋅2−1)/(0.06/2).

Simplifying, we have P6=$4,500 ((1.03)12−1)/(0.03). Therefore P6=$63,864.13. Our final answer is 63900.
