insens350 [35]

Answer:

The annual difference between Option 1 (15 years) and Option 2 (20 years) is $7,211.19 in favor of the first one.

Explanation:

Giving the following information:

Option 1:

Number of years= 15

FV= 450,000

i= 0.0525

Option 2:

Number of years= 20

FV= 450,000

i= 0.0525

To calculate the annual cash flow, we will use the following formula on each option:

A= (FV*i)/{[(1+i)^n]-1}

A= annual cash flow

<u>Option 1:</u>

A= (450,000*0.0525) / [(1.0525^15) - 1]

A= $20,464.72

<u>Option 2:</u>

A= (450,000*0.0525) / [(1.0525^20) - 1]

A= $13,253.53

The annual difference between Option 1 (15 years) and Option 2 (20 years) is $7,211.19 in favor of the first one.
