- INTEREST
- ========
-
- The interest facility allows complex interest calculations to be made
- on any account.
-
- The INTEREST window opens directly from an account and works only
- on that account. Data entry and results are both completed within
- the window.
-
- START AND END DATES
-
- Start and end dates are simply selected, by default thay are set to
- today and one year ago.
-
- PERIOD
-
- The period for the compounding of interest is selected by
- clicking over the appropriate period button, if you select 'days' then
- enter the number of days in the field below 'days'. Note that as you
- change start and end dates the 'Date from' and 'To' dates change also.
-
- BALANCES
-
- If there is only one interest rate applicable to all balances
- then ignore the 'Balances structure' fields. When you click on the top
- left box of the 'Rates' table 'All' will appear in the 'Balances
- structure' field.
-
- TIERED RATES
-
- If the interest rates are tiered you will need to enter
- the balances up to which interst rates apply, enter the lowest value
- in the left hand 'Balances structure' box-this value can be
- negative-then move to the next box (RETURN or ARROW key) and enter the
- next value, when you have entered all the values you require then
- click over the top left 'Rates' box and the box to the right of the
- last 'Balance structure' box that you have completed will be filled in
- with ">" plus your last figure. If you have made a mistake in the
- order of entering these figures you will be given a warning message.
- All figures can be edited at any time (delete the old figure and write
- in a new one-the arrow keys will not work within the box during
- editing). If you get it completely wrong double click on the CLEAR
- button and all data will be cleared. Having set the balances structure
- just fill in the appropriate interest rates in the top row of the
- 'Rates' table.
-
- DATES FOR RATES
-
- If the interest rates have changed during the period of
- concern to you then you must enter the dates at which the new rates
- have started. To do this move the mouse pointer over one of the
- blue/white arrows next to the first empty box under the 'Date from'
- box (with the start date in it). The pointer will change shape. The
- select button changes days, the menu button changes months (no auto
- repeat) and the adjust button changes years. Click select and a date
- one day in advance of the previous date will appear in the box. Set up
- the required dates, if you try to set a date out of sequence a warning
- will be given. Note that the start date can be changed to any value
- irrespective of the date of the first rate entry and the end date is
- also independent of the last rate date.
-
- RATES
-
- Clicking in the top left 'Rates' box will automatically check the
- 'Balances structure' data and enter 'All' or ">" in the appropriate
- boxes. To complete the 'Rates' table merely fill in the boxes for all
- balances and dates entered. If you do not fill all these in a warning
- will be given when you try to calculate the interest. Note that RETURN
- will move the cursor to the right and all ARROW keys work on empty
- boxes but not full ones.
-
- CALCULATION
-
- To calculate the interest click the CALCULATE button. If you have
- forgotten to enter an interest rate you will be given a warning
- message at this stage. If you have got it right every entry in the
- period will be evaluated for interest and the results will be
- displayed in the lower part of the window.
-
- RESULTS
-
- There is a result shown for the end of each period, the 'balance'
- shown is the balance including the calculated interest and this is
- used in the calculation for the next period so that interest is
- compounded correctly. If more than 25 'periods' are calculated only
- the last 25 are displayed and a message to this effect will be
- displayed.
-
- CLEAR
-
- Clicking the CLEAR button once will delete the results but leave the
- 'Balances structure' and 'Rates' intact for editing and further
- calculation if required. Double clicking clears all data and resets
- dates to default values.
-
- SAVE
-
- With the 'Balances structure' and 'Rates' intact they may be saved to
- ease your next interest calculation! Clicking the SAVE button saves
- these figures to a file specific to this account and next time you
- select 'interest' these figures will be entered into the window
- automatically. They can then be CLEARed if required.
-
- EXIT
-
- Closes the window.
-
- PRINT
-
- Selecting PRINT will print a full report detailing the Balances
- structure, Rates and results. This is also available as a text file in
- the 'data.print' directory if you wish to export it to another word
- processor.
-
- ENTER
-
- Results can be entered on to the account by clicking the ENTER
- button, this will close the INTEREST window and leave the account
- display showing the interest entry(s)-note that the amount of this
- entry(s) is not added to balances because it is not actual interest
- but notional, it can however be 'checked'.
-
- EDITING
-
- All entries can be edited, however the DATES cannot be deleted
- without CLEARing the window fully-this is normally no problem as the
- start and end dates can still be altered and any rates outside the
- period of interest (no pun intended) will simply be ignored.
-
- NOTES
-
- The interest is calculated for each entry from the date of the
- transaction. Small differences will occur from bank calculations if
- these dates do not tie up exactly those on bank statements or if
- interest is not credited in this manner under the terms of the
- account.
