An amortization Program for creating a table of payments
This is an amortization table for home mortgages, but it should work for anything else that follows that type of math - say a car loan.
Usage:
python amortization.py -csv|screen -P # -i # -n #
example with principle of $270,000, 4.44% interest, for 30 years:
python amortization.py -csv -P 270000 -i .0444 -n 360
-csv: create a Comma Separated Values file to import into excel
-screen: print the amortization table to screen
-P: for # enter principal amount
-i: for # enter interest as a decimal
-n: for # enter number of months
If you want to see the effect of extra monthly payments, create a file called extraprincipal and put the values in one after another one line at a time.
Ex:
0
200
300
0
would be 0 extra principal the first month, 200 extra the second month, etc
Runs on QT. Install those libraries via pip (especially if you run on Windows) or your package manager (on Linux).
Run amortization-gui.py
After entering data into the fields, hit calculate. It will print the data into the field below in a spreadsheet-like view. It will also create a CSV file called amort.csv. You can import this into any program that can take in CSV files. If you import it into a spreadsheet program you can then create a PDF (or anything else you'd do with a spreadsheet.
