Martha’s RRSP is currently worth $97,000. She plans to contribute $5000 at the beginning of every six months until she reaches age 58, 12 years from now. Then she intends to use half of the funds in the RRSP to purchase a 20-year annuity making month-end payments. Five years later she will use half of the funds then in her RRSP to purchase another 20-year annuity making month-end payments. Finally, at age 68, she will use all of the remaining funds to purchase a third 20-year annuity also making end-of-month payments. What will be her monthly income at age 65 and at age 70 if her RRSP and the annuities earn 7.5% compounded monthly?
