- INTEREST CALCULATOR WINDOW
- ==========================
-
- This window allows you to perform interest calculations for both
- regular and lump sum investments and loans. An immediate result is
- displayed using the data input and optionally an account is generated
- to allow you to perform more complex calculations using the 'See
- Account' Interest function.
-
- TYPES
-
- There are 4 baisc types of calculation:
-
- *Lump Sum Savings - the interest will be calculated then the total of
- original sum plus interest, and the interest alone will be displayed.
-
- *Regular Savings - the interest on each payment will be calculated
- assuming the entered interest rate applies to the whole period. The
- total of regular payments and interest, and the interest alone will be
- displayed.
-
- *Lump Sum Loan - the regular monthly repayment needed to pay for this
- loan will be calculated assuming a 31 day delay from loan to first
- repayment. The regular repayment will be displayed together with the
- total sum to be repayed. Alternatively an option to calculate the
- regular repayment of interest only (such as in an Endowment mortgage)
- can be selected. In this case the result displayed is the regular
- interest repayment and the total interest to be repayed.
-
- *Regular Loan - this assumes you receive a regular loan over the
- period and works out the total to be repayed at the end of the period.
- The result displays the total amount owed and the interest element
- included within this total.
-
- VARIABLES
-
- The variables that can be changed are:
-
- *Total period - in months or years, the period over which interest is
- to be calculated.
-
- *Compound period - in months, the period over which interest is
- compounded. Normally set to 12 months, if it is changed then the APR%
- box after calculation will show the equivalent annual interest rate to
- be different from that set.
-
- *Interest rate - the actual percentage rate per annum to be used
- irrespective of the compound period set. If an APR is used here then
- 12 months should be set for the Compound period.
-
- *Regular period - the period between regular savings payments or
- regular loan receipts.
-
- MAKE ACCOUNT
-
- Selecting this option makes the calculator generate a full account -
- 'Fixed.CalcAcct' using the data provided as well as performing the
- 'Quick' calculation. This account can then be displayed, modified, and
- added to through the TRANSACTION form which in this case is limited to
- Internal transactions on CalcAcct only. The Interest function can then
- be used to perform more complex analysis using tiered interest rates
- and periodic chages to rates.
-
- APR%
-
- The interest rate entered is taken as a flat annual rate over the
- compounding period - so if 10% is entered and the compound period is 6
- months then 10% will be used during each 6 month period. This would be
- equivalent to a 10.25% rate using a compounding period of a year. The
- APR% box shows this equivalent yearly rate whenever a new result is
- calculated.
-
- CONTROLS
-
- *Calculate - this performs the calculations and displays the result.
-
- *Clear - this clears all user entered data and resets default values.
-
- *Exit - this closes the window and resets default values.
-
- *Create - this replaces Calculate if the Make Account option is chosen
-
- *Interest Only? - this button appears only when Lump Sum Loans is
- selected, if chosen then only the regualr interest payments are
- calculated.
