Quote from a customer:

"Last week I had a meeting with my accountants and my bankers. We were working on the pro forma balance sheets and cash flows for a new project I'm working on.

They were all asking why I had switched to the iPhone for I used to be a die hard "brandX phone" fan. I said that one could do so much more. They said "yea...sure" (they were all using "brandX phones") until I started using your calculator. We were analyzing different payment and amortization schedules. They were so impressed by how easily we could figure out the amount of interest, principal and remaining loan balance for any certain period or combination of periods that in the end they were saying "I have to get me one of those".

 Great product. Thanks."

    I have used this calculator for over 20 years first as a handheld and then on both my iPad and Droid phone. As an Engineer and later Financial Advisor I’ve used most functions it offers and am very satisfied with it. When I took the CFP test 14 years ago (10 hours under strict monitoring) I brought two with me to make sure I had backup. Didn’t think I ever need it (and didn’t) but I wouldn’t take a chance.
  • I continue to use this calculator every day...
