Jody's grandparents deposited $1,200 annually to a savings account and increased the deposits at a rate of 3% annually for 5 years. What is the present value of this investment earning 8% annually?
There is a growing annuity.
Given,
First deposit = F = 1,200
Rate = r = 8% = 8/100 = 0.08
Number of year = n = 5
Rate of growing = g = 3% = 3/100 = 0.03
Present value = P =?
The formula is as below:
P = [F/(r – g)] [1 – {(1 + g) / (1 + r)}^n]
= [1200/(0.08 – 0.03)] [1 – {(1 + 0.03) / (1 + 0.08)}^5]
= [1200 / 0.05] [1 – (1.03/1.08)^5]
= 24,000 × [1 – 0.953703^5]
= 24,000 × [1 – 0.788979]
= 24,000 × 0.211021
= 5,064.50 (Answer)
