Compute-Only Variables
You cannot enter values manually for compute-only variables, for example, net
present value (NPV). To compute a value, display a compute-only variable and
press C. The calculator computes and displays the value based on the
values of other variables.
When you display a compute-only variable, the COMPUTE indicator reminds
you to press C to compute its value. After you press C, the 7 indicator
confirms that the displayed value has been computed.
Automatic-Compute Variables
When you press # or " to display an automatic-compute variable (for
example, the Amortization worksheet INT variable), the calculator computes
and displays the value automatically without you having to press C.
Enter-or-Compute Variables in the TVM Worksheet
You can either enter or compute values for the TVM worksheet variables (N, I/Y,
PV, PMT, and FV).
Note: Although you do not have to be in the standard-calculator mode to assign
values to these variables, you must be in the standard-calculator mode to
compute their values.
• To assign the value of a TVM variable, key in a number and press a
variable key.
• To compute the value of a TVM variable, press C, and then press the
variable key. The calculator computes and displays the value based on the
values of other variables.
Enter-or-Compute Variables in Prompted Worksheets
You can either enter or compute values for some prompted worksheet
variables (for example, the Bond worksheet YLD and PRI variables). When you
select an enter-or-compute variable, the calculator displays the variable label
with the ENTER and COMPUTE indicators.
• The ENTER indicator prompts you to press ! to assign the keyed-in
value to the displayed variable.
• The COMPUTE indicator prompts you to press C to compute a value for
the variable.
