Are there any good loan calculators ?
-Something with Spitzer tables aka "equal payments"
-Open-Source
-preferably desktop GUI (Qt)
-preferably cross-platform (Windows + Linux) -- Android is a bonus !

NOTE: Debian package list returned zero results for keyword "loan" or "mortgage".

The only thing i came across was gcalctool,which provides advanced and some financial functions. I would think your best resource would likely be a financial webpage - many, many financial number crunching calculators online. ...or since you want something off-line just customize a spreadsheet with your most commonly used forumulas. Googling 'equal payment calculator spreadsheet' provides lots of resources that you could probably implement into libreoffice.
