Questions On January 1 st, 2002 Jack deposited $1, 000 into Bank X to earn an interest rate of j per year compounded semi-annually. On January 1 st, 2007 he transferred his account to Bank Y to earn an interest rate of k per annum compounded quarterly. On January 1 st, 2010 the balance at Bank Y was $1, 990. 76. If Jack could have earned the interest rate of k per annum compounded quarterly from January 1 st, 2002 to January 1 st, 2010 his balance would have been $2, 203. 76. What was ratio of k/j?

We also know: We have an initial investment, that earned j compounded semi-annually for five years FVN=n=PV 0 x(1+ j/2)2*N = BALANCE 07=1, 000 x(1+ j/2)2*5 The BALANCE 07 will earn a rate of 10% (k) per annum compounding quarterly
Questions We also know: We have an initial investment, that earned j compounded semi-annually for five years FVN=n=PV 0 x(1+ j/2)2*N = BALANCE 07=1, 000 x(1+ j/2)2*5 The BALANCE 07 will earn a rate of 10% (k) per annum compounding quarterly for 3 years: BALANCE 10 = BALANCE 07 x (1+0. 1/4)3*4 1, 990. 76 = 1, 000 x(1+ j/2)2*5 x (1+0. 1/4)3*4 THEREFORE: k/j = 0. 1/0. 08 = 1. 25 1, 990. 76 = 1, 000 x(1+j/2)10 x 1. 02512 1. 48025 = 1, 000 x(1+j/2)10 / ^1/10 then solve for j => j = 0. 08
Questions The proceeds of a $10, 000 death benefit are left on deposit with the insurer at an effective annual interest rate of 5%. The balance at the end of 7 years is paid to the beneficiaries in equal monthly payments of X for 10 years (120 payments). During the payout period, interest is credited at an annual rate of 3%. What is the value of X?

During the payout period, interest is credited at an annual rate of 3%. What is the value of X? We can calculate the balance at the end of year 7: FV 7=PV 0 x(1+ i)7 = FV 7=10, 000 x(1+ 0. 05)7 = $14, 071 We can then calculate the annuity payment by: Solving for A ANNUITY DUE With PVA = $14, 071 i = 0. 03/12 = 0. 0025 N=120 (i. e. 12*10) ANNUITY: $119. 01
Questions Your father now has $1, 000 invested in an account that pays 9. 00%. He expects inflation to average 3%, and he wants to make annual constant dollar (real) end-ofyear withdrawals over each of the next 20 years and end up with a zero balance after the 20 th year. How large will his initial withdrawal (and thus constant dollar (real) withdrawals) be?
