The 10bii Financial Calculator is a versatile and powerful financial calculator which features more than 105 different functions for financial analysis, business, statistics, and general mathematics. Modeled after the extremely popular 10bII Financial Calculator by Hewlett Packard, the 10bii Financial Calculator combines precise mathematics, intuitive display, and ease-of-use in one compact package. It allows you to easily calculate loan payments, interest rates, amortization, time value of money, investment value, and more using a combination of powerful and intuitive equation-writing functionality and helpful worksheets.

By expanding on HP's traditional presentation, the 10bii Financial Calculator allows quick and intuitive building and visualization of TVM (Time Value of Money) calculations and Uneven Cash Flow scenarios and lets you type in whole equations for easy review and one-touch evaluation.

With the 10bii Financial Calculator, you can:

Calculate Time Value of Money (Length of Term, Present Value, Nominal Interest, Loan Payments, Future Value) and see the cash flow diagram produced for you via the Graph TVM key. Values for N, PV, I, PMT, and FV are displayed right above their keys for easy reference.

Easily enter Uneven Cash Flows, including rapid calculation of Net Present Value and Internal Rate of Return. A dedicated interface makes adding, editing, deleting, and reordering uneven cash flows a breeze.

Switch between Nominal and Effective interest rates with the simple touch of a button.

Enter and analyze statistical data points. Includes standard calculations such as standard deviation, mean, and linear regression forecasting.

Never has using a financial calculator been so easy or intuitive. The 10bii Financial Calculator is truly powerful enough for the professional but accessible enough for everyone. It is an ideal tool for teaching the power of compounding interest, analyzing potential deals or business ventures, or just doing math problems, and sharing the results of your work with others.

The 10bii app is the updated version of the 10b app. Also known as the 10b2.

This is a nice app, however, recent update (December 12, 2021) crash unlocked 10bii++ purchase. Please fix. Note: Developers have immediately noticed the issue and are currently fixing it. This is a very advanced app which I like to use and use it daily. Edit: I have talked to developer Kenny Wyland several times. Ken seems like a good guy. I was a little bit upset because this is my favorite app, and I have all the Android calculator apps. I like the 10bii+ because the clicking sounds when you touched the keys are just right (the clicking sounds of the competitor calculators are a bit too soft, using a different tone, or no sound). The layout of the buttons and the background color are perfect, professionally desired. The algorithm behind the app is solid. These 2 aspects beat all the competitors. Thanks.

We released v4.3.3 a few hours later and fixed this issue. It should be working normally now.

Probably one of the most handy tools to run a quick analysis from my phone reverse engineering a mortgage if I am missing a piece of data. I don't like that it is not tied to the app for your PC though. It's a separate charge and at a markup. Why am I paying twice for the same product? Can we not match user keys across platforms?

Thank you! To answer your question, when buying an app through one App Store (like Google Play) that doesn't make it available through another Store (like the Mac or Microsoft App Store) b/c those app stores are managed by different companies. MS doesn't want to let you install the PC version when you paid Google for the Android version.

Up until recently, I loved this app. The amotization payments are now incorrect. This seems to have changed sometime over the past couple of years (not sure when). Not sure what happened in the coding but DO NOT rely on the loan numbers being right. They are close but not correct.

Hi Stuart, the AMORT hasn't changed in ~8 years. This is likely just a misunderstanding. Maybe Begin/End Mode. Also each bank has their own policies for how to calculate amort schedules and deal with rounding fractional pennies. Amorts will often vary from bank to bank by a few pennies. Please email theteam@inadaydev.com and we can clear this up.

What's new

If you experience any problems, please contact theteam@inadaydev.com asap so we can get it fixed for you. Fixed issue with main calculator button text being too wide on certain phones. Upgraded to latest Google Play billing API. Fixed some crash issues related to Android 11. Fixed issue with switching to 10bii+ features repeatedly.
