About 10BA Pro Financial Calculator

The 10BA Financial Calculator works like the industry standard financial calculator such as the HP 10B, HP 10BII, or the HP 10BII+ emulator; however, we add tons of unique features that makes this app be the most convenient financial calculator that you have ever used.

Single-Access Key
No need to use a shift key to access the yellow or the blue functions. The Single-Access Key feature enables you to activate the yellow and the blue functions quickly and conveniently.

Integrated Cheatsheet
No need to memorize anything. Each functions on the calculator has a cheatsheet containing brief description of how the function works, and examples.

Anti-Boring
Replace the background with an image from your photo gallery. You can even make it transparent like the interface you often see on TV, kind of.

For TI Users, before you post a one-star review asking where the CPT button is.
There is no [CPT] button by design so don't look for it. The app does not need the [CPT] key. To find future value [FV] instead of [CPT][FV] just tap [FV]. Read the integrated Help feature for details, or simply contact us!

Privacy Policy
10BA Pro Financial Calculator does not collect, store, or transmit information about its users. The use of "allow to take pictures and record video" permission is for the application to use the back camera and achieve transparent background effect. The use of "allow to access photos, media, and files on your device" permission is to enable you to select an image from the gallery folder as calculator background. The permission is also necessary if you want to convert the amortization schedule into Excel format because the app needs to save the converted file into the Documents folder.

Reviews for 10BA Pro Financial Calculator

I absolutely love this app. I use present value calculations and loan amortization many times per week and loved my hp17bll financial calculator so changing seemed like a big ask but this app is so slick and with built in help that allows you to do even the most sophisticated calculations (even those you don't do often) it was easy. It also has things your HP doesn't have, like a complete amortization table on the screen. Super product and at $2 it is the deal of the century. still love it 12/25
