A year from now, you plan to begin saving for your retirement by making a deposit into a new savings account that has an expected return of 6% compounded weekly. You plan to continue depositing the same amount each year until you retire in 40 years. You expect to make withdrawals in the amount of $1,000 from your savings account every month for 35 years after you retire. Assume you were asked to find the amount you will need to deposit into your savings account each year until you retire in order to fund your retirement. In your solution, you would need to use the annuity present value equation to find the present value at your retirement date of the withdrawals you expect to make each month during your retirement. What interest rate would you use in this equation?
