Answer:
The present value of annuity is $657,720
Explanation:
Present value of an annuity is the total cash value of all future annuity payments, given a determined rate of return or discount rate.
Present value of annuity = P![[\frac{1 - (1 + r)^{-n} }{r}]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B1%20-%20%281%20%2B%20r%29%5E%7B-n%7D%20%7D%7Br%7D%5D)
where: P is the periodic payment, r is the rate per period and n is the number of periods.
The discount rate is compounded for the first 7 years and thereafter.
The present value of annuity in the first 7 years can be calculated as:
P = $1800 × 12 = $21,600 per year, r = 8% and n = 7 years.
= 21600![[\frac{1 - (1 + 0.08)^{-7} }{0.08}]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B1%20-%20%281%20%2B%200.08%29%5E%7B-7%7D%20%7D%7B0.08%7D%5D)
= 21600![[\frac{0.42}{0.08}]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B0.42%7D%7B0.08%7D%5D)
= $113,400
Thus, the present value after the first 7 years = $113,400.
Therefore, the present value of the annuity = 113,400![[\frac{1 - (1 + 0.1)^{-9} }{0.1}]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B1%20-%20%281%20%2B%200.1%29%5E%7B-9%7D%20%7D%7B0.1%7D%5D)
= 113,400![[\frac{0.58}{0.1}]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B0.58%7D%7B0.1%7D%5D)
= $657,720
The present value of annuity is $657,720.
