A Selecting Interest Calculation for a Period
with a Partial Month

calculate interest for a period with a partial month. Before
performing each type of calculation, first use Configuring

A CMPD Mode Financial Calculation
Variables (VARS)
•Variables n, I, PV, PMT, FV, P/Y, and C/Y are used in
the CMPD Mode.
• The values of CMPD Mode variables are retained even if
you change to another mode. Note, however, that CMPD
Mode variables are also used by other modes, so
performing an input or calculation operation may change
the values assigned to them.
• Though CMPD Mode variables are financial calculation
variables, they are also used by arithmetic and function
operations in the COMP Mode.
