## It's a work in progress...

I'm still working on this and I haven't had a chance to do a write up about it. It take you step by step through some formulas and it can take expressions as input. I'll do a quick example for the future value of an investment of $50,000 compounded daily at 1.59% APR for 5 years:

Set the "PV" to 50000, an i of 1.59/100/365 (percent / 100 / # of compounding periods) and set n to 365*5+1 (5 years + 1 day for the leap year). If done correclty the answer should be $54,139.54.
