k SET UP Items

u Payment {BGN}/{END}. Specifies {beginning of the period} / {end of the period} payment u Date Mode {365}/{360}. Specifies calculation according to a {365-day} / {360-day} year u Periods/YR. (Bond) {Annual}/{SEMI}. Indicates an {annual} / {semi-annual} period 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.

2. Simple Interest

This calculator uses the following formulas to calculate simple interest.

uFormula

365-day Mode 360-day Mode
SI' = n PV i 365 SI' = n PV i 360

I% 100 I% i= 100 i=

After configuring the parameters, press one of the function keys noted below to perform the corresponding calculation. 1(SI). Simple interest 2(SFV). Simple future value
An error (Ma ERROR) occurs if parameters are not configured correctly. Use the following function keys to maneuver between calculation result screens. 1(REPT). Parameter input screen 6(GRPH). Draws graph
After drawing a graph, you can press 1 (TRACE) to turn on trace and read calculation results along the graph. Each press of e while trace is turned on cycles the displayed value in the sequence: present value (PV) -> simple interest (SI) -> simple future value (SFV). Pressing d cycles in the reverse direction.
Press i to turn off trace. Press i again to return to the parameter input screen.

3. Compound Interest

This calculator uses the following standard formulas to calculate compound interest.

uFormula I

PV+PMT u
(1 + i u S)[(1+ i)n1] i(1 + i)

1 (1 + i)

PV= (PMT u + FV u )

FV= PMTu + PV

PV + FV u
PV : present value FV : future value PMT : payment n : number of compound periods I% : annual interest rate i is calculated using Newtons Method.

log n=

(1 + i S ) PMTFVi (1 + i S ) PMT+PVi log(1 + i)
S = 0 assumed for end of term S = 1 assumed for beginning of term
(1+ i u S)[(1+ i)n1] i(1+ i)n

1 (1 + i)n

F(i) = Formula I
(1+ i S)[1 (1+ i)n] PMT + (1+ i S)[n(1+ i)n1] i i +S [1(1+ i)n] FV n(1+ i)n1

uFormula II (I% = 0)

PV + PMT n + FV = 0

PV = (PMT u n + FV )

FV = (PMT u n + PV )

PMT =

PV + FV n

PV + FV PMT

A deposit is indicated by a plus sign (+), while a withdrawal is indicated by a minus sign ().
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.

I%' = (1+

[P / Y ] I% ) 100 [C / Y ]

[C / Y ]

P/Y : installment

periods per year

C/Y : compounding
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

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

[P / Y ]

I% [C / Y ] ) 1 [C / Y ]100 100
The value of I%' is returned as the result of the I% calculation. Press 2(CMPD) from the Financial 1 screen to display the following input screen for compound interest. 2(CMPD)
n.. number of compound periods 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
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 Newtons 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. After configuring the parameters, press one of the function keys noted below to perform the corresponding calculation. 1(n). Number of compound periods 2(I%). Annual interest rate 3(PV). Prevent value (Loan: loan amount; Savings: balance) 4(PMT). Payment (Loan: installment; Savings: deposit) 5(FV). Future value (Loan: unpaid balance; Savings: principal plus interest) 6(AMT). Amortization screen

An error (Ma ERROR) occurs if parameters are not configured correctly. Use the following function keys to maneuver between calculation result screens. 1(REPT). Parameter input screen 4(AMT). Amortization screen 6(GRPH). Draws graph
After drawing a graph, you can press 1(TRACE) to turn on trace and read calculation results along the graph.
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.

CF2 CF3 CF4

CF7 CF6

CF1 CF0

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.

NPV = CF0 +

n: natural number up to 254
CF2 CF3 CFn CF1 + + ++ (1 + i ) (1 + i )2 (1 + i )3 (1 + i )n

NFV = NPV (1 + i )

0 = CF0 +
CF2 CF3 CFn CF1 + + ++ (1+ i) (1+ i)2 (1+ i)3 (1+ i)n
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.
Initial value of N when NPV > 0. Press 3 (CASH) from the Financial 1 screen to display the following input screen for Cash Flow. 3(CASH)

360-day Date Mode Calculations
The following describes how calculations are processed when 360 is specified for the Date Mode item in the SET UP screen. If d1 is day 31 of a month, d1 is treated as day 30 of that month is used. If d2 is day 31 of a month, d2 is treated as day 1 of the following month, unless d1 is day 30.

9. Depreciation

Any of the following four methods can be used to calculated depreciation.

uStraight-Line Method

The straight-line method calculates depreciation for a given period.
(PVFV ) {Y1} u n 12 (PVFV ) SLj = n (PVFV ) 12{Y1} u SLn+1 = n 12 SL1 = ({Y1}G12)

SL j n PV FV j Y1

: depreciation charge for the jth year : useful life in years : original cost (basis) : scrap value (salvage value) : year : number of depreciable months in first year
Depreciation for an item acquired part way through a year can be calculated by month.

uFixed Percentage Method

Fixed percentage method can be used to calculate depreciation for a given period, or to calculate the depreciation rate.
I% {Y1} I% FPj = (RDVj1 + FV ) 100 FP1 = PV FPn+1 = RDVn ({Y1}G12) RDV1 = PV FV FP1 RDVj = RDVj1 FPj RDVn+1 = 0 ({Y1}G12)
FPj : depreciation charge for the jth year RDVj : remaining depreciable value at the I%
end of jth year : depreciation rate
uSum-of-the-Year's Digits Method
The sum-of-the-year's-digits method calculates depreciation for a given period.
n (n +1) 12 {Y1} n' = n 12 (n' integer part +1)(n' integer part + 2*n' fraction part ) Z' = 2 {Y1} n (PV FV ) SYD1 = Z 12 n' j+2 )(PV FV SYD1) SYDj = ( ( jG1) Z' 12{Y1} n' (n +1)+2 SYDn+1 = ( )(PV FV SYD1) ({Y1}G12) Z' 12 Z= RDV1 = PV FV SYD1 RDVj = RDVj 1 SYDj
SYDj : depreciation charge for the jth year RDVj : remaining depreciable value at the

end of jth year

uDeclining Balance Method
The declining balance method calculates depreciation for a given period.

DB1 = PV

I% Y1 100n 12 I% 100n
RDV1 = PV FV DB1 DBj = (RDVj1 + FV ) RDVj = RDVj1 DBj DBn +1 = RDVn RDVn+1 = 0 ({Y1}G12) ({Y1}G12)

: depreciation charge for the jth year RDVj : remaining depreciable value at the end of jth year I% : factor (%)

Installing STAT2 changes the function menu of the STAT Mode list input screen (initial screen) as shown below.
Pressing a function key that corresponds to the added item displays a menu that lets you select one of the functions listed below. 3(TEST). Test (Chapter 2, page 6) 4(INTR). Confidence interval (Chapter 3, page 31) 5(DIST). Distribution (Chapter 4, page 42) The SORT and JUMP functions available with ALGEBRA FX2.0 are moved to the TOOL menu (6 and 1) by STAT2.
uCalculation of the Coefficient of Determination (r2) and MSE
STAT2 adds calculation of the coefficient of determination (r2) for quadratic regression, cubic regression, and quartic regression. The following types of MSE calculations are also added for each type of regression.

Linear Regression.

MSE = MSE =

1 nnn2

(y (ax + b))

uEstimated Value Calculation for Regression Graphs
STAT2 adds a Y-CAL function that uses regression to calculate the estimated y-value for a particular x-value after a paired-variable statistic regression graph is drawn. The following is the general procedure for using the Y-CAL function. 1. After drawing a regression graph, press 62 (Y-CAL) to enter the graph selection mode, and then press w. If there are multiple graphs on the display, use f and c to select the graph you want, and then press w. This causes an x-value input dialog box to appear.
2. Input the value you want for x and then press w.
This causes the coordinates for x and y to appear at the bottom of the display, and moves the pointer to the corresponding point on the graph. 3. Pressing v or a number key at this time causes the x-value input dialog box to reappear so you can perform another estimated value calculation if you want. 4. After you are finished, press i to clear the coordinate values and the pointer from the display. The pointer does not appear if the calculated coordinates are not within the display range.
The coordinates do not appear if [Off] is specified for the [Coord] item of the [SETUP] screen. The Y-CAL function can also be used with a graph drawn by using DefG feature.
u Regression Formula Copy Function from a Regression Calculation Result Screen
In addition to the existing regression formula copy function that lets you copy the regression calculation result screen after drawing a statistical graph (such as Scatter Plot), STAT2 also adds a function that lets you copy the regression formula obtained as the result of a regression calculation. This type of copy operation is performed by pressing 6(COPY).
k Tests, Confidence Interval, and Distribution Calculations
STAT2 adds functions for performing tests, confidence interval, and distribution calculations. This manual fully describes each of these calculations in separate chapters: Chapter 2 Tests, Chapter 3 Confidence Interval, and Chapter 4 Distribution.

uParameter Settings

The following describes the two methods you can use to make parameter settings for test, confidence interval, and distribution calculations. Selection With this method, you press the function key that corresponds to the setting you want to select from the function menu. Value Input With this method, you directly input the parameter value you want to input. In this case, nothing appears in the function menu. Pressing i returns to the list input screen, with the cursor in the same position it was at before you started the parameter setting procedure. Pressing ! i (QUIT) returns to the top of list input screen. Pressing w without pressing 1 (CALC) under Execute item advances to calculation execution. To return to the parameter setting screen, press i, A, or w.

uCommon Functions

The symbol s appears in the upper right corner of the screen while execution of a calculation is being performed and while a graph is being drawn. Pressing A during this time terminates the ongoing calculation or draw operation (AC Break). Pressing i or w while a calculation result or graph is on the display returns to the parameter setting screen. Pressing ! i (QUIT) returns to the top of list input screen.
Pressing A while a calculation result is on the display returns to the parameter setting screen. Pressing u 5 (GT) after drawing a graph switches to the parameter setting screen (GT function). Pressing u 5 (GT) again returns to the graph screen. The GT function is disabled whenever you change a setting on the parameter setting screen , or when you perform a u 3 (SET UP) or ! K (V-Window) operation. You can perform the PICT menu's screen save or recall functions after drawing a graph. The ZOOM Function and SKETCH function are disabled. The TRACE function is desabled, except for the geaph display of two-way ANOVA. The graph screen cannot be scrolled. After drawing a graph, you can use a Save Result feature to save calculation results to a specific list. Basically, all items are saved as they are displayed, except for the first line title. Each time you execute Save Result, any existing data in the list is replaced by the new results.
