You make a series of quarterly deposits every quarter starting at the end Quarter 1 and ending at the end of Quarter 36. The first deposit is $1,100, and each deposit increases by $500 each Quarter. The nominal annual interest rate is 7%, and is compounded continuously. What is the Future Value of these series of deposits at the end of Quarter 36?

Answer:

the fund will be valued after 36 quarters: 443.027,75

Explanation:

This will be an arithmetic progression with h = 500

the continously rate we are going to convert to a quarterly equivalent rate:

[tex]e^{0.07} =(1+r)^{4}[/tex]

[tex]\sqrt[4]{e^{0.07}}-1 = r__{quarter}[/tex]

r = 0.017654022

Then we calculate future value of an ordinary annuity of 1,100

[tex]C \times \frac{(1+r)^{time} -1 }{rate} =FV\\[/tex]

C     1,100

time 36

rate 0.017654022

[tex]1100 \times \frac{(1+0.0176540221507619)^{36} -1}{0.0176540221507619} =FV\\[/tex]

FV $54,682.8156

plus future value of the increases:

[tex]\frac{h}{i} ( S_{n:i}- n)[/tex]

500/0.017654022 = 28,322.15773

Sn:i

[tex]1 \times \frac{(1+0.0176540221507619)^{36} -1}{0.0176540221507619} = FV\\[/tex]

FV 49.7117

n =   36

Sn:i - n = 13.7117

$28,322.15773 x 13.7117 = $388.344,93

Now we add both:

$54,682.8156 + $388.344,93 = 443.027,75
