- RPI Calculator 2.1
- (C) Richard Smedley 1997-1998
- =============================
-
- Have you ever wondered if your wages are really keeping up with the cost of
- living, or whether constantly increasing prices are really justified?
-
- RPI converts money from one year to another, so that you can compare how
- much things used to cost with how much they cost now. For example, ú25.00
- in 1990 is worth the same as ú29.40 in 1995.
-
- This is extremely useful for things like seeing if your wages are really
- keeping up with the cost of living, or finding out whether the value of
- your house/car has increased by more than inflation.
-
- Several datafiles are supplied, allowing you to perform a wide range of
- calculations; including UK Pounds Sterling (RPI) and US Dollars (CPI). You
- can even use the program for making future guestimations based on current
- values!
-
-
- INSTALLATION
- ------------
-
- This program is compatible with all EPOC32 machines, such as the S5 and
- Geofox.
-
- 1. Create the folder "System\Apps\RPI" on any drive. You may need
- to select `Show system folder' from your system prefs to do this.
-
- 2. Copy the following files into that folder:
-
- America.dat
- England.dat
- RPI.aif
- RPI.app
- RPI.hlp
- Wages_UK.dat
-
- The RPI icon will now appear on your Extras bar.
-
- The first time you use the program, the Options window will automatically
- appear for you to select which data file you wish to use.
-
-
- USING THE PROGRAM
- -----------------
-
- The RPI window contains the following boxes:
-
- Amount - the amount that you want to convert
-
- From - the "from" year
-
- To - the "to" year
-
- Enter the required info into each box, and then press the return key.
-
- For example, suppose that in 1996 you were paying ú68.50 per week in rent,
- and wanted to check whether or not your rent has increased in line with the
- overall rate of inflation. Enter the following:
-
- Amount: 68.50
- From: 1996
- To: 1998
-
- The program will then display the answer: ú73.08
-
- This means that if you're now paying more than ú73.08 for your rent, then
- you'll know that your rent has increased by *more* than the current rate
- of inflation. Likewise, if you're paying less than this, you'll know that
- it has increased by *less* than the rate of inflation.
-
- (That example uses the English.dat datafile!)
-
- You can perform similar calculations in the same way on things like, for
- example, the price of a loaf of bread or a can of pop, or the amount that
- you paid for your house compared with its current value, and so on. The
- potential uses are almost infinite.
-
-
