ASelecting Interest Calculation for a Period with a Partial Month

You can select compound interest or simple interest to calculate interest for a period with a partial month. Before performing each type of calculation, first use Configuring Settings (page E-16) to select either compound interest or simple interest for the dn setting.

ACMPD 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.
