This is calculated using FV function in Excel with these inputs :
rate = 8%
nper = 40
pmt = -5000
FV is calculated to be $1,295,283
2]
This is calculated in two stages : first find the FV of the retirement account at the end of 5 years , then add $100,000 to the account, and find the FV of the retirement account at the end of 40 years
FV at end of year 5 is calculated using FV function in Excel with these inputs :
rate = 8%
nper = 5
pmt = -5000
FV is calculated to be $29,333
After selling the business for $100,000 the retirement account is worth $129,333. This earns 8% per annum compounded for 35 years. The ending value is calculated as $129,333 * (1 + 8%) ^ 35 ==> $1,912,333
3]
This is calculated using FV function in Excel with these inputs :
rate = 8% / 4 (converting annual rate into quarterly)
nper = 40 * 4 (40 years * 4 quarters per year)
pmt = -5000 / 4 (here it is assumed that the annual deposit is converted into 4 quarterly deposits)
FV is calculated to be $1,423,119
4]
This is calculated using the PMT function in Excel with these inputs :
rate = 5%
nper = 20 (20 years expected remaining life)
pv = $1,295,283
PMT is calculated to be $103,937
5]
This is calculated using the PMT function in Excel with these inputs :
rate = 5%
nper = 20 (20 years expected remaining life)
pv = 1,295,283
fv = -200,000 (amount required to be left at end of 20 years)
PMT is calculated to be $97,888
