The routines in this program are all self prompting. When the main
menu is visible, just select the routine that you want to run by entering
the letter shown next to the routine. You will then see a new screen that is
waiting for your input. Enter the information that is being requested, then
press ENTER. You will be prompted for more information. When you are no
longer being prompted for information, the program will calculate and
display the results.

When you enter values you may use commas and dollar signs. DO NOT use
a percent sign or a cent sign. If you do so, the progam will not accept the
input and an error message will indicate that you did not enter a number.
The progam will then wait for you to reenter the information.

Remember, all interest rates are expressed in an annualized figure.
Periods per year means how often are the monies compounded. Withdrawals and
deposits are done at the start of each compounding period. Thus, if the
routine asks for a rate of interest, you might reply 12.5, meaning the
annual rate of interest is a 12.5 percent. If the rate is compounded
quarterly, then when asked how many periods, you would respond with 4. And
finally if you want to withdrawal or deposit $1,000 a year you would have to
divide this amount by four ($250) and enter that figure since there are four
periods per year. (SIDEKICK by Borland would be great for this calculation.)

At the end of each routine you are prompted with M(ain Menu) or
R(epeat)? Type M if you want to return to the main menu or type R if you
want to run another of the same calculations with different input. You must
return to the Main Menu to quit the program.

The following is a brief description of what each routine does:

Future Value of a Deposit

This routine will calculate the future value of a deposit. In other
word how much will a given amount be worth after a period of time when
invested at a given rate of interest.

Future Value of a Series

This routine is just like the one above accept that it assumes that
there is a series of deposits being made. That is, there are deposits being
made of a fixed amount at the start of each compounding period. These
deposits are made for the life of the investment. Example: Your IRA funds
are invested at a rate of 8.8 percent compounded quarterly. You want to
invest $2,000. each year for a period of 15 years. For this program you
must input $500.00 when ask for the deposit since it is assumed that the
deposit is made at each compounding period. The program will return to you
the value of the account after the 15 years assuming a deposit was made each

Payment Required for Future Sum

This one is fun. You want to be worth a billon in 5.5 years! How much
do you have to deposit each compounding period at a particular rate of
interest to make it happen.

Present Value of Amount

Your Brother-In-Law owes you 100,000 big ones due in 7.2 years. He
offers to pay you $90,000 dollars today. This routine will tell you if it
is a good deal. You can throw the bum out if the present value exceeds the
90,000 that he is offering. On the other hand you can show your wife just
how dumb the guy is if the present value is less than $90,000.

Present Value of a Series
As above accept that the routine will tell you the present value of a
series of payments. Example: Your profit sharing may be drawn down in one
lump sum or you may accept a series of payments. Use this routine to tell
you which is the best way to go. If the present value is worth more than the
series of payments for the period, you'll know what to do.

Withdrawal of Funds

Congratulations! You just won the Publishers Clearing House's Grand
Prize of $125,00 and being a frugal person, you immediately run over to the
corner office of E. F. Hutton and deposit the funds in thier money market
accout. Now the question is, if you withdrawal a little bit every month,
how long will your prize last you? There will be no guessing with this
routine. This routine takes into account any interest rate, compounded for
any period and any size of withdrawal.

Interest Rate Earned

You held some stock for 3.75 years. When you bought it it was worth
$7,500 and when you sold it it returned, after commissions, $12,274. What is
the effective annual interest rate? If it is more that the average money
market rate for the period, pat yourself on the back.

Net Present Value, Uneven Cash Flow (NPV)

Very simple, if the result is positive, you have found an investment
that is returning your desired yield. If it is negative, it is not giving
you the return on your investment that you would hope to get. Routine asks
for amount invested and annual interest rate that you would LIKE to earn.
You then supply the cash flows that you expect. Each one can be different.
To stop entering cash flows, enter 0.

Time to Double

At a given rate of interest, at a particular rate of compounding how
long will it take for you to double your money.

Equivalent Interest Rate
CitiBank is offering 9.9 percent compounded daily. First Boston is
offering 9.5 percent compounded quarterly. Now just exactly who is giving
you the best deal? Run this routine to find out.

Straight-Line Depreciation

Computes an annual depreciation table using the above method.

Declining-Balance Depreciation

Computes an accelerated depreciation schedual and prints a table. Use
these table to help decide which is the best method to depreciate the office

Sum-of-Years-Digits Depreciation

Computes an accelerated depreciation schedual and prints a table. Use
these table to help decide which is the best method to depreciate the office

Break-Even Point

You are about ready to market the next best seller. This routine asks
you for your total of fixed costs. (Phone, Rent, Insurance etc.), Cost of
manufacturing the product (total cost of materials etc.) and the selling
price of the item. It then returns to you the number of units that must be
sold to break-even in your venture.

Economic Ordering Quantity (EOQ)

What is the most economical quantity to order for an item? Allows you
to input the overhead costs in processing an order. Then the routine takes
the total annual units of an item used and the unit carrying cost (interest
rate your funds earn multiplied by the purchase price for each unit) of the
item to calculate the most economical quantity to order. Buyers and Bosses
should love this one!

Sales Price with Discount

What is the total prices with tax for an item selling at a particular

Weighted Average

Calculates an average value for input of different values and amounts.
If you bought stock the first of each month at different prices and in
different quantities this routine will tell you what you paid in terms of
the average price per share. To stop entering values, enter 0 at a value
prompt. This routine will allow you to average up to 1,000 different values
and units. If you need it to allow for more inputs, contact the author!

Monthly Payment Calculation

Your in a fix and you need to borrow 10,000 from the local loan shark.
You can borrow the funds for 2.3 years at an annual rate of interest of 22.3
percent. What will your monthly payment be to the quy?

Mortgage Schedule

This will show you a loan schedule and what portion of any payment is
applied to interest and what part is applied to principal. You are asked
for the loan amount, interest rate, term of the loan, and the year for
which you want the table shown. At the end of the program you are prompted
with the usual M(ain Menu) and R(epeat) as well as A(other Year). The
difference between REPEAT and ANOTHER YEAR is that another year will use
the same loan conditions and just report back a table for a different year.
Repeat allows you to change the conditions of the loan. Note: you can see
a table for the twelve months following the 4.5 year mark, for example,
just by entering 4.5 when asked for what year. Also note, that when
prompted for the year the program will not allow you to enter a year
greater than the term of the loan. This routine can be used at tax time
when you need to see how much interest you paid on a loan.

Remaining Balance

Things are a little easier now and you want to pay off some loans.
This routine will show you what the balance is on a loan after any
particular payment.

Accelerated Payments

You were just promoted to head boss and with it you got a big fat
raise. Now you can pay an extra $125.00 toward the principal on your
mortgage. This routine will show you when your loan will be paid off and
how much interest you will save over the remainder of the loan. The
program prompts you for the terms of the loan (years, amount, & interest
rate) as well as the year of the increase and the extra amount paid. When
asked for year, DO NOT enter a year such as 1985, rather enter the year in
which the increase payments started, such as 3 for the third year or 9 for
the ninth year. Just for fun, assume you have a 30 year $75,000 mortgage
and you decide to pay and extra $75. per month after the fifth year. Take
a quess as to what year the loan will be paid off in and how much interest
you will save for the balance of the loan. Now run the routine and see how
close you came to the correct answer. Unless you are in finance, quaranteed
you will be suprised.

Balloon Payment

You are considering using one of the new "creative" ways to finance a
home. This calculates what the balloon payment is after a particular
number of years.

Affordable House Price

This will help you decide what mortgage you can afford. The routine
asks you for the annual interest rate on the loan, the length of the loan,
your annual income, an estimate of property taxes and insurance, the
percentage of your income for payments and the percentage you want to put
down. It will use these values to figure what you can afford when shopping
for a home.

Mortgage With Second

This will calculate the total monthly payment when carrying two
mortgages. It is assumed that only the interest on the second mortgage is
being paid.

Rental Property Analysis

If you are a land lord, or considering being one, this routine will
calculate your monthly cash flow from your rental property. The routine
considers your mortgage, annual interest rate, term of the loan, annual
insurance, taxes, & maintanence and the monthly income. (If you are a
renter, you could also figure out what your landlord is making off of you!)

I hope that these routines have some practical value for you.
