Hi all, I wrote a powerful little script that acts as a quick calculator that will determine how much money you should end up with (and other information), should you lend X @ Y rate, with a daily compounding feature inspired by Poloniex, which varies between 0-2day minimum time-frames for margin lending. In the future, may update to change the compounding feature, but most on the web already accommodate long-term, long-compounding period loan earnings, so this is a bit more unique to the crypto-space.

If you have questions, or need a video, let me know here and I will try to help you out. Edit: Seems like the code here displays without indentation, which is very important, if indents don't copy over, you can use this PasteBin link with full Syntax Highlighting : http://pastebin.com/SLgyArfJ
