To determine the FV simply press and the FV of -$200.04 is displayed.
FV
The HP is programmed so that if the PV is + then the FV is displayed as - and vice versa, because the HP
assumes that one is an inflow and the other is an outflow. When entering both PV and FV, one must be
entered as negative and the other as positive.
Example 2:
What is the PV of $500 due in 5 years if the interest rate is 10 percent? Clear first and then enter the
