- DOCUMENTATION FOR THE FINANCE I ROUTINES
-
- 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 quarter.
-
-
- 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 computer.
-
- 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 computer.
-
-
- 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
- discount?
-
- 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?
-
-
- I hope that these routines have some practical value for you.
- Remember, if you find them of value please support my on going efforts to
- supply user supported software by sending a contribution to the address
- found on the title page of the program. If you use the software to create
- or maintain income that such a contribution should be tax deductable.
- Check with your account.
-
- If you find these programs easy to use and you have a need to solve
- other equations (engineers, financial advisers, researchers, etc.) contact
- me so that we can explore the possibilities of encompassing your needs in
- a similiar interface so that you can have a clerical person do a series of
- calculations for you.
