Note the following points regarding SET UP screen settings whenever using the Financial
Mode.
•Drawing a financial graph while the Label item is turned on, displays the label CASH for the
vertical axis (deposits, withdrawals), and TIME for the horizontal axis (frequency). Axis
labels do not appear on the TVM graph.
•The number of display digits applied in the Financial Mode is different from the number of
digits used in other modes. The calculators automatically reverts to Norm 1 whenever you
enter the Financial Mode, which cancels a Sci (number of significant digits) or Eng
(engineering notation) setting made in another mode.

k Graphing in the TVM Mode
After performing a financial calculation, you can use 6 (GRPH) to graph the results as shown
below.
•Pressing 1 (TRACE) while a graph is on the display activates Trace, which can be used to
look up other financial values. In the case of simple interest, for example, pressing e
displays PV, SI, and SFV. Pressing d displays the same values in reverse sequence.
•Zoom, Scroll, and Sketch cannot be used in the Financial Mode.
•Whether you should use a positive or a negative value for the present value (PV) or the
purchase price (PRC) depends on the type of calculation you are trying to perform.
•Note that graphs should be used only for reference purposes when viewing TVM Mode
calculation results.
•Note that calculation results produced in this mode should be regarded as reference values
only.
•Whenever performing an actual financial transaction, be sure to check any calculation results
obtained using this calculator with against the figures calculated by your financial institution.

uConverting between the nominal interest rate and effective interest rate
The nominal interest rate (I% value input by user) is converted to an effective interest rate
(I%') when the number of installments per year (P/Y ) is different from the number of
compound interest calculation periods (C/Y ). This conversion is required for installment
savings accounts, loan repayments, etc.
P/Y:installment
periods per year
C/Y:compounding
periods per year
When calculating n, PV, PMT, FV
The following calculation is performed after conversion from the nominal interest rate to the
effective interest rate, and the result is used for all subsequent calculations.
i = I%'÷100

After I% is obtained, the following calculation is performed to convert to I%'.

I%............................... annual interest rate
PV ............................... present value (loan amount in case of loan; principal in case
of savings)
PMT ............................ payment for each installment (payment in case of loan;
deposit in case of savings)
FV ............................... future value (unpaid balance in case of loan; principal plus
interest in case of savings)
P/Y.............................. installment periods per year
C/Y.............................. compounding periods per year
Important!
Inputting Values
A period (n) is expressed as a positive value. Either the present value (PV ) or future value
(FV) is positive, while the other (PV or FV ) is negative.
Precision
This calculator performs interest calculations using Newton’s Method, which produces
approximate values whose precision can be affected by various calculation conditions.
Because of this, interest calculation results produced by this calculator should be used
keeping the above limitation in mind or the results should be verified.

2-4 Cash Flow (Investment Appraisal)
This calculator uses the discounted cash flow (DCF) method to perform investment appraisal
by totalling cash flow for a fixed period. This calculator can perform the following four types
of investment appraisal.
•Net present value (NPV )
•Net future value (NFV )
•Internal rate of return (IRR)
•Pay back period (PBP)
A cash flow diagram like the one shown below helps to visualize the movement of funds.
CF0
CF1
CF2CF3CF4
CF5CF6
CF7
With this graph, the initial investment amount is represented by CF0. The cash flow one year
later is shown by CF1, two years later by CF2, and so on.
Investment appraisal can be used to clearly determine whether an investment is realizing
profits that were originally targeted.

In this formula, NPV = 0, and the value of IRR is equivalent to i × 100. It should be noted,
however, that minute fractional values tend to accumulate during the subsequent
calculations performed automatically by the calculator, so NPV never actually reaches
exactly zero. IRR becomes more accurate the closer that NPV approaches to zero.
