this is OT for linux-il, but anyone trying the script should consider
some of the following.
1) this is a very nice idea, thanks for the effort.
2) 1% saving interest as default is way too low, today even without
bargaining
you can get 2.25% for a bi-yearly program (and still be shafted), 2.5%
seems a more
realistic value (though investing in bonds may give much higher yield).
3) for the mortgage interest you need to split for misrad-hashikun (~4%
IIRC) and
bank's mortgage.
4) saving in a bi-yearly plan can give you "ribit de ribit" i.e.
exponential growth
e.g. using 10 by-yearly programs, at a measly 2.5% a year, gives:
1.05+1.05^2+...+1.05^10 -> 32% profit
instead of 2.5% linear interest:
1.05 + 1.1 + ... + 1.5 -> 27.5% profit
( of course exponential growth gives better results for higher
interest rates)
such an option should be added to the script.
5) note this script gives the result for a simple arithmethic series (or
geometric, using
above saving method), no need to calculate saving for each year. (if you
want I'll send you the calculations, you can add them to the project)
6) regarding the script: the yearly printouts are also not needed.
