INTRODUCTION

Calc version 5.0 is full featured financial software which

will provide solutions to many common financial questions. It

includes a wide range of financial functions: Present Value,

Future Value, Discounted Cash Flow Analysis, Future Value of an

Annuity, Present Value of an Annuity, Pay Off Amount for a

Loan, Amortization, and Loan Payment Calculations. It also

includes Comparative programs, where two situations are

presented side by side for ease of comparing the efficacy of

alternative investment or loan decisions. These comparative

programs include Future Value Comparison, Present Value

Comparison, Future Value of an Annuity Comparison, Present

Value of an Annuity Comparison, Loan Payment Comparison, and

Annuity Payment Comparison. It also includes programs which

will solve for unknown interest rates for a Lump Sum Deposit,

Future Value of an Annuity, Present Value of an Annuity,

Annuity Payment, and Loan/Lease payments. It also includes

programs to Convert Annual Percentage Rates to Effective Rates

and Effective Rates to Annual Percentage Rates. Calc also

includes a pop-up Calculator and Calendar.

Calc was designed for ease of use and contains an integrated

help facility, which will pop up context sensitive help at any

time, when the

and then pressing

Pressing

the entry field. The help facility is quite extensive and

contains most of the information found in this documentation

file. It also contains an explanation of each routine and

examples aimed at providing the user with a conceptual

understanding of the routine. For this reason, discussion

pertaining to conceptual use of the program is intentionally

limited in this document.

INSTALLATION

Calc requires at least a CGA monitor and an IBM or compatible

computer with 256K of memory, preferably with a hard drive.

Calc can be installed on a floppy disk, but access time to

files will be slow. The disk must not be write protected as

Calc does periodic writes. The six (6) files you should have

received are: FCALC.EXE, FCALC.API, FCALC.SCR, FCALC.HLP,

FCALC.DAT, and the file you are currently viewing, FCALC.DOC.

Copy these six (6) files to the same directory, preferably on

your hard drive in a directory named FCALC. All six files must

be in the same directory and the program must be started from

this directory. At the prompt, merely type FCALC and then

press enter to run the program.

MENU SYSTEM

The Calc menu is a standard "pull-down" menuing system. To

activate the menu strike the Alt key and press the first letter

of the menu item you wish to select. Highlight the selection

of choice and press enter. As an alternative to highlighting

the desired selection, the "hot key" of the desired item may be

pressed. the "hot key" for any menu item is the key which is

highlighted in intense white.

COMMAND LINE

The 25th line command bar displays the date and time as well as

available keys/commands. These keys vary with the user's

location within a program and therefore, it is important to

reference this command line to properly navigate the program.

ENTERING VARIABLES

If an error is made while making an entry in an Calc field it

may be corrected, one character at a time, by using the

The entire entry can be erased by striking the

the user has hit the return key and exited the field, pressing

the Cursor Up key will return the user to the previous field to

make necessary corrections.

The Cursor Dn key enters the same number that was previously

entered in a field and advances the cursor to the next entry

field. This key is useful when the user wishes to change only

one or two variables in a program for comparison purposes. The

Cursor Dn key when in "Comparison" programs will enter the

variable from Case A into Case B, if Case B had no prior entry.

Decimal points are placed in variable fields by striking the

period key or the Del key when the NUM lock key is toggled on.

Appropriate dollar signs, commas, and percentage signs are

automatically inserted by the program.

DEFAULT PARAMETERS

Calc programs will accept a maximum number of 999,999,999.99

in many input fields. Output is limited to 9,999,999,999.99.

Input which results in output exceeding the maximum may be

preceded by "%" which indicates that there are leading digits

which have been truncated from the output. The user is

cautioned that Calc solutions preceded by % are inaccurate.

If values are entered into fields which are "out of range" a

dialog box will appear and explain the default error.

COMPOUNDING PERIODS

The maximum Compounding Periods Per Year are only limited as

explained in the paragraph above.

Ads are often seen which state "Compounding from day of deposit

to day of withdrawal". This type of statement implies daily

compounding, but how many days are there in a year? When

compounding periods are daily, two popular methods are used for

computing days in a year - the exact method and the ordinary

(Banker's Rule). The exact method assumes 365 days in a year

and the ordinary assumes twelve, 30 day months, or 360 days in

a year. To determine the convention used in any particular

investment, the user needs to check with the particular

investment institution. Calc programs utilize the exact

method.

Compounding could occur every hour, minute, second, or for that

matter, every instant. Compounding every instant is the

concept of "Continuous (Instantaneous) Compounding". The

formula for Continuous compounding utilizes "e" the base of the

system of natural logarithms. This constant is approximately

2.718281828459............

Discounted Cash Flow utilizes the base of the natural log to

compute the Net Present Value. To simulate Continuous

Compounding in other programs, enter a large number, (such as

999,999) in the Compounding Periods Per Year.

In addition, Calc programs will accept any numerical input

for compounding periods, within the limits explained above;

however, compounding periods other than 1, 2, 3, 4, 6, 12, 24,

26, 52, 360, 364, 365, or 366 have little practical value,

because it would be unlikely to find investments with

compounding periods differing from these.

AMORTIZATION

The Amortization program produces standard amortization

schedules. The schedules can either be displayed to the screen

or printed on the printer. Pressing

Amortization program provides information on printing to the

screen or printer.

Calc allows up to ten (10) different interest rates over the

life of a loan. An * denotes the commencement of an interest

rate when the amortization schedule is printed or displayed to

the screen.

Number of Years can be up to thirty (30). A loan for

fractional years (such as an 18 month loan) may be entered as

1.5 in the Number of Years field.

Payments Per Year (PPY) may be 1, 2, 3, 4, 6, 12, 24, 26, or

52. The following chart further explains PPY:

PPY Frequency Meaning # Pmts in Full Year

--- --------- ------- -------------------

1 Annual Once/year 1

2 Semi-Annual Every 6 months 2

3 Tri-Annual Every 4 months 3

4 Quarterly Every 3 months 4

6 Bi-Monthly Every other month 6

12 Monthly Each month 12

24 Semi-Monthly Twice each month 24

26 Bi-Weekly Every other week 26 or 27

52 Weekly Each week 52 or 53

As most individuals who are paid either Weekly or Bi-Weekly

are probably aware, there is one day of the week which will

occur 53 times in non leap years, and two days of the week

which will occur 53 times in leap years. Consider for a moment

that 52 X 7 = 364. There are 365 days in a year, 366 in a leap

year. Ergo, it is apparent that one day of the week (two in a

leap year) will occur 53 in a given year. Where applicable,

Calc recognizes this fact and therefore if Weekly or Bi-Weekly

is selected, certain years will contain either 53 or 27 PPY,

respectively. The date selected as the 1st Payment Date will

establish the Day of the Week for payment of a loan, and when

this day of the week occurs 53 times in a years, the number of

payments per year is adjusted accordingly.

Calc Amortization assumes that payments are made in arrears,

meaning that the borrowed funds were received in the previous

period. Another assumption is that compounding periods are the

same as the payment period. Calc uses the normal method of

amortization which means that the payment remains the same

thru the life of the loan (except final payment), unless the

interest changes.

The user is reminded that the final payment of an Amortized

Loan is often slightly higher or lower than the other payments.

The final (Last) payment is displayed by Calc Amortization.

ANNUITY PROGRAMS

An annuity is a series of equal payments or receipts for a

specified number of periods.

An Ordinary Annuity has payments at the END of each period of

time.

An Annuity Due has payment at the BEGINNING of each period of

time.

A Simple Annuity has payment dates which match the compounding

periods. All Calc annuity programs are Simple Annuities and

therefore, Calc annuity programs should not be used when

compounding does not coincide with periodic deposits.

In applicable Calc annuity programs the user will be prompted

by a dialog box and will need to indicate if the Annuity to be

calculated is Ordinary or an Annuity Due.

The Present Value Annuity Program does not present a prompt for

input as to an Ordinary or Annuity Due. This is because the

equation utilized by the program assumes an Ordinary Annuity.

The Discounted Cash Flow program is based on an Ordinary

Annuity equation and therefore, the Cash Flows alluded to in

the program are assumed to occur at the end of each period.

PAY OFF

The Calc Pay Off program calculates the amount required to pay

off an amortized loan before the final payment. The equation

utilized is based on the Unpaid Balance Method. Consequently,

the Pay Off program will not solve for loans which are based on

the Rule of 78s or an alternative convention.

FUTURE VALUE (FV)

FV is the amount to which a deposit will grow by a given future

date when compounded by a given interest rate. This Calc

program will solve the question: if I deposit $x today at x%

interest what will be the value of the deposit at the end of x

years?

PRESENT VALUE (PV)

PV is the current value of a future sum. This Calc program

will answer the question: How much do I need to deposit today

at x% interest to have $x at the end of x years?

FUTURE VALUE ANNUITY (FVA)

FVA is the amount to which a series of equal deposits will grow

by a given future date. This Calc program will answer the

question: If I deposit $500 at the end of each month, at 10%

interest, what will be the value of these deposits at the end

of 9 years. To determine the Fv of an Annuity with a starting

balance run Calc Future Value to compute the Fv of the

starting balance, then run Calc FV Annuity, and then add the

results of the two programs together. The Calculator is handy

in storing values between Calc programs.

ANNUITY PAYMENT

Calc Annuity Payment answers the question, how much do I need

to deposit each period, for a certain number of years to

achieve a desired future sum. For instance, suppose that on

the day your child is born you decide to start saving for his

college education. You estimate that 18 years from now, a four

year college education will cost $100,000. You have an

investment which will pay 10% interest and your deposits will

be made at the beginning of each month. By entering these

variables into this Calc program, the user will find that the

required monthly payment to achieve this future sum is $165.12.

CONVERT EFF/APR

This Calc Program converts the Effective Interest Rate (Eff)

back to the Annual Percentage Rate (APR). As defined in all

Calc programs, the APR accounts for compounding only once per

annum, while Eff produces the Effective Interest Rate when

compounding periods are taken into account.

For instance, the interest on $1,000 at 12% APR for 10 years is

$2,105.00. The interest on $1,000 at 12% APR, with interest

compounded daily (365 days in year) is $2,319.46. In this

example the APR is 12% while the Eff rate is 12.75%.

CONVERT APR/EFF

This Calc program does the inverse calculation of EFF/APR.

DISCOUNTED CASH FLOW ANALYSIS (DCF)

Discounted Cash Flow Analysis combines two methods of ranking

investment decisions - the Internal Rate of Return (IRR)

Method and the Net Present Value (NPV) Method.

NPV is equal to the present value of future returns, discounted

at the marginal cost of capital, minus the present value of the

cost of the investment.

IRR is the rate of return on an asset investment, calculated

by finding the discount rate that equates the present value of

future cash flows to the cost of the investment.

This Calc program will answer the question: If I purchase an

apartment building for $50,000 and my required rate of return

is 12%, and the future cash flows over the next 5 years will be

$5,000 each year, and the resale value of the apartments after

5 years will be $75,000, and $10,000 depreciation is taken,

has my investment goal been met?

If the NPV equals 0, then the investment goal has been met and

the IRR is 12%. If the NPV is greater than 0, then the

investment goal has been exceeded, and the IRR is greater than

12%. If the NPV is less than 0, then the investment goal has

not been met and the IRR is less than 12%.

The number of Cash Flows in this Calc program is limited to

99.

FIND LOAN PAYMENT

This Calc program determines the payment for a loan given the

variables of interest rate charged, duration, and number of

payments per year. If an amortization schedule is required,

the Calc companion program "Amortization Schedule" should be

used.

PRESENT VALUE ANNUITY (PVA)

There are two ways to conceptualize the PVA. The first is that

a PVA is a lump sum that can be deposited today that will

amount to the same final total as would the periodic payments

of an annuity. The second is that a PVA is a lump sum that

could be deposited today so that equal periodic withdrawals

could be made.

As an example of the second way of looking at a PVA, $6532.89

must be deposited today at 10% interest compounded annually, to

provide withdrawals (or payments) of $1500 at the end of each

year for the next 6 years.

As an example of the first way of looking at a PVA, $6532.89

left in an account for 6 years at 10% interest, would produce

the same final total as deposits of $1500 at the end of each

year for six years.

The PVA program assumes an ordinary annuity. That is, payments

occur at the "END" of each period.

COMPARISON PROGRAMS

Calc Comparison Programs provide the user with a visual method

to evaluate the efficacy of alternative investment decisions or

loans. Entries are first made in the Case A column, then in

the Case B column. Comparison programs included are Future

Value, Present Value, Fv Annuity, Pv Annuity, Loan Payment, and

Annuity Payment.

INTEREST FIND

Calc interest programs find the interest rate when the

interest rate is unknown. Since a direct equation does not

exist, except for lump sums, to solve for an unknown interest

rate, Calc will make successive approximations at the interest

rate until it is found. The result will be an approximation.

To test its accuracy, plug the result into the appropriate

Calc program.

CALENDAR

When initially popped-up the calendar displays the current

month calendar. A 25th line command bar displays information

necessary to change the calendar's date.

CALCULATOR

Pops up a four function calculator which is useful for doing

simple calculations on the fly and for storing numbers when

moving from one Calc program to another. A 25th line command

bar displays information relative to the calculator's

operation. The help facility also provides additional

information.

DOS SHELL

Calc remains in memory but exits temporarily to the DOS

command prompt. You can then perform any service supported by

COMMAND such as Dir, Type, Sort, or executing another program

that memory constraints will allow. Calc when loaded,

occupies approximately 253K of memory.

If you change directories while shelled to DOS, be sure to

return to the Calc directory before returning to Calc.

Failure to do so will result in an error message stating that

required files cannot be found.

When shelled to DOS and you wish to return to Calc, type

"Exit" at the DOS prompt.

Loading Memory Resident Programs (TSRs) while shelled to DOS,

will produce erratic results when returning to Calc. If TSRs

are used they should be loaded prior to loading Calc.
