    12.6: Application - Planning Your RRSP

    Due to the nature of these questions, five Application questions, two Challenge questions, and one Spreadsheet question are offered.


    1. When Criss turns 55, 35 years from now, he wants his RRSP savings to pay him the equivalent of $35,000 annually today with 2.4% annual inflation. He thinks his annual contributions can earn 9% compounded annually increasing by 4% per payment. Upon retirement, he wants to receive end-of-month payments for 30 years and estimates his account can earn 5.35% compounded annually. What is his first RRSP contribution payment at the end of the year?
    2. After graduating college at age 22, Kandahar immediately gained employment in the accounting field. He thinks that his career path will follow the “standard” path and he will retire at age 65. He feels he could live comfortably off of $30,000 in today’s dollars, with expected inflation of 2.1% annually. In retirement, he plans on receiving month-end payments for 13 years with 3.75% compounded monthly interest. Suppose his investment earns 8% compounded quarterly and he will increase his contributions by 0.9% per payment. What is his first quarterly RRSP contribution three months from now?
    3. Aisha and Richard are getting married, 33 years before they hit age 65. Neither has any RRSP savings to date. They figure that together in retirement they would like to earn the equivalent of $60,000 today plus 3% annual inflation. After retiring, they want to receive payments at the end of every three months for 15 years while the account earns an estimated 4.35% compounded semi-annually. If their RRSP can earn 8.25% compounded monthly and they plan on increasing contributions by 1.5% per interval, what first semi-annual payment is made today by each of them to achieve their joint goal?
    4.

    1. Sanchez is eligible to receive retirement benefits of $901.01 at age 65, but decides to start receiving them when he turns 60 instead. This incurs a 36% penalty on his benefits. By taking his retirement benefits at age 60, he will realize a monthly saving of $184.80 in retirement fund contributions. Both the benefits and contributions savings are expected to rise monthly by 0.15%.

In retirement, he will use the accumulated savings, which are expected to earn 4.5% compounded quarterly, to top up his retirement benefit payments to his pre-penalty amount. The monthly benefits are expected to rise monthly by 0.15%.
