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."

User Reviews
Used this calculator since 1992, when I actually bought the device. I love its simplicity and accuracy in business. Some things should always be there and this one just gets better and better.
Still using, it seriously continues to GROW ON You! Glad for the updates, and your continued willingness. Please, CONTINUE the GREAT programming. KennyW STILL GREAT programming…
Most app used on my phone!
Excellent
Use it constantly and is one of my daily go-to apps!
I have the original HP10BII calculator. One day the batteries died and I realized I could get this one for less $$$ than replacing the batteries in my “real” calculator, plus it goes everywhere my phone goes and so it’s always available. Then I discovered it has many other features on the “back side” as well. Thanks HP for a great calculator; thanks developer(s) for an even better app!
This is the only calculator I use, and I have relied on it for years. I’ve never had a single problem or glitch with it. I am so thankful to the developer for making it available.
I have used this wonderful app for many years now. I’m a retired professor of engineering and worked in private practice. In my work, I used this calculator as my go-to outside of my pc, and continue to use it even more for a variety of everyday projects. The available different kinds of other integrated calculators are super helpful as well.
Works great
I have used this calculator to amortize mortgage loans and compare real estate investment opportunities for years. It has always been a solid application and has performed wonderfully.
