- LOANS
- =====
-
- This program is intended to simplify your loan calculations. Any-
- one of four loan values may be calculated, given the other three
- standard values. The program may be used for standard loans or
- mortgages, by altering the compounding period. You will be pro-
- vided with a schedule of your loan payments. Any of the four loan
- values may be altered for any period(s) and the schedule recalc-
- ulated. Lumpsum payments may be made, with or without payment re-
- calculation. Other recalculation scenarios are possible, see the
- list of examples following the gadget explanations. Finally, you
- you may print out a copy of your schedule, starting with any per-
- iod you desire.
-
-
- Gadgets:
- ========
-
- Rate - This represents the nominal interest rate payable on a
- yearly basis.
-
- Payment - Your monthly loan payment.
-
- Term - The number of monthly loan payments, maximum 300.
-
- Principal - The original outstanding value of your loan.
-
- Compounding - The number of times that interest is compounded per
- year on your loan. Zero represents simple interest.
- Most loans are calculated using simple interest,
- while most mortgages are compounded semi-annually.
-
- Period - The period in which you wish to change one of your
- four original values. Also the period which the
- print out will begin. You must select a period to
- change before making any re-calculations.
-
- NOTE: The left mouse button may now be used to sel-
- ect this feature.Simply point to the period desired
- in the schedule and click the mouse button.
-
- Calculate - Used to start the calculation of the fourth value.
- This is also used to re-calculate values once any
- changes have been made.
-
- Print - Dumps your schedule to a printer.The print out will
- begin with the period entered in the Period Gadget.
-
- Date - The date the first payment is to be made.Entered as
- follows, 'JUN 1987'. The month must be any standard
- three letter abreviation, capitals are optional.The
- year may be '0', '1987' or any other numeric value.
-
- Lumpsum - The prepayment you wish to make on your loan. This
- may be entered for any period(s). This may be used
- with or without re-calculation.
-
-
- Menu Items:
- ===========
-
- About - A requester showing shorter explanations of the gadgets
- listed above.
-
- Reset - Returns all variables to their original value. This will
- also erase your existing loan schedule, BE WARNED!
-
- Quit - Self explanatory. This is also available in the output
- window by selecting the close gadget. Remember, YOUR DATA
- WILL BE LOST!
-
-
- Title Bar:
- ==========
-
- Should you make an incorrect selection or produce a value outside
- of the programs range, you will be notified of your error in the
- window's title bar. This should prevent any visits from the GURU.
- I HOPE.
-
- Examples:
- =========
-
- The standard calculations are fairly obvious, but let us look at
- some of the more obscure possibilities.
-
- Having made your original calculation, you would like to make a
- Lumpsum Payment at some point in your schedule. Assuming your
- Lumpsum Payment will not affect your payment (unlikely) all you
- have to do is:
- (1) Enter the period your payment is to take place.(Mouse option)
- (2) Enter your Lumpsum Payment.
- (3) Select the Calculation gadget.
-
- Given the same conditions, let us assume your payment will be re-
- calculated. This is the procedure to follow:
- (1) Enter the period your payment is to take place.(Mouse option)
- (2) Enter your Lumpsum Payment.
- (3) Enter ZERO '0.0' for your payment.
- (4) Select the Calculation gadget.
-
- The same principal may be applied to any of the four values. If
- you wish to re-calculate a value after a change,simply enter Zero
- for that value and select the calculate gadget.
-
- One more practical example.
-
- Assume your original values have been entered and your schedule
- produced. Now you wish to change the Interest Rate in Period 13
- (Year 2),make a Lumpsum Payment and have your Payment calculated.
- Here is the procedure.
- (1) Enter the period to change.(Mouse option)
- (2) Enter your new Interest Rate.
- (3) Enter your Lumpsum Payment.
- (4) Enter Zero for your Payment.
- (5) Select the Calculation gadget.
-
- This order need not be specific, except that you must select the
- Period to alter first and the Calculation gadget last. The com-
- pounding period could also have been changed.
-
-
- Although this program is designed to calculate monthly Loan
- Payments it is possible to use it for other than standard loans.
- Let us say that your payments are to be made bi-monthly, all you
- need to do is enter twice the nominal yearly Interest Rate.If the
- Payments are to made yearly, the Interest Rate that you enter is
- 12 times the nominal yearly rate. Of course your print out will
- not be correctly formatted.

- HISTORY
- =======
-
- This is my first C program. The project was originally started as
- an exercise in programming. It has grown from a simple user in-
- put program to the Intuition based program you now see. The pro-
- gram has undergone several revisions and GURU hunts, as I learned
- more about the Amiga's operating system. I hope you find it use-
- ful.
-
- I have considered a couple of future additions, including file
- capabilities and a detailed mouse based selection system. This would make the user's changes much simpler.
