A Other CNVR Mode Calculations
Example 2: To convert an effective interest rate (EFF) to
a nominal interest rate (APR)
• In step 2 of the basic procedure (Example 1), select “APR:
Solve”.
A CNVR Mode Financial Calculation Variables
(VARS)
•Variables n and I are used in the CNVR Mode.
•A value is assigned to
I whenever you perform an EFF
or APR calculation in the CNVR Mode.
• The values of CNVR Mode variables are retained even if
you change to another mode. Note, however, that CNVR
Mode variables are also used by other modes, so
performing an input or calculation operation may change
the values assigned to them.
• Though CNVR Mode variables are financial calculation
variables, they are also used by arithmetic and function
operations in the COMP Mode.
A Calculation Formulas
APR : nominal interest rate (%)
EFF :effective interest rate (%)
n : number of annual compoundings
k Cost/Sell/Margin Mode
• The Cost/Sell/Margin (COST) Mode lets you calculate
cost, selling price, or margin after inputting the other two
values. You can input the cost and selling price, for
example, and calculate the margin.
