"The current value of the Crusoes’ investment portfolio is USD 1,330,000. Scolari has determined that when the couple retires four years from today, a portfolio valued at USD 2,200,000 could sustain them through their retirement years. Scolari expects the Crusoes to earn an after-tax return of 4.5% per year on their current portfolio and any additions to the portfolio prior to retirement. The Crusoes believe they can continue to save an after-tax total of USD 35,000 per year during the next four years.

**C. Demonstrate, given the current assumptions, that the Crusoes will not be able to retire in four years in accordance with their existing plan. Show your calculations.**

So obviously it is N=4, PV=1330000, i=4.5%, PMT=-35000, CPT FV. I know you always input PV as a negative number, but I always screw up the PMT input on the calculator. How do you know if payment is -35000 or 35000?
