Question

Note, the mode of compounding and the mode of making your payments must match to use the formula. Therefore, we must first find the effective rate of 5 percent compounded quarterly and then use that rate in the formula, with $2,000 as the annuity or payment made at the beginning of each period. The effective rate is (1+.05/4)-1-0.0509. This rate is plugged into the formula for a future value of an annuity due as the i or rate per period: 2. The city of Glendale borrows $48 million by issuing municipal bonds to help build the Arizona Cardinals football stadium. It plans to set up a sinking fund that will repay the loan at the end of 10 years. Assume a 4 percent interest rate per year. What should the city place into the fund at the end of each year to have $48 million in the account to pay back their bondholders? This is a future value of an ordinary annuity problem. The formula is:

Explanation / Answer

FV=x*1.04^9+x*1.04^8.....x

=x*(1-1.04^10)/(1-1.04)

This FV must be 48

So, x=48*(1-1.04)/(1-1.04^10)

x=3.997965

Hence, it must place 3.997965 million at the end of each year starting from year 1
