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.

I have used this app for over a decade as a full-time mortgage loan originator. It is fantastic and it allows me to always have my calculator with me! It does everything that my 'real' calculators do and I prefer it in this App format to the real handheld calculator. totally worth it.

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.

So far so good. I like how it is so far but at the same time you should tell people that they will have to make an additional purchase of $3.99 within the app to unlock the rest of the features (basically the rest of the blue buttons). This calculator is truly a 10bii + after you make the second purchase but it is actually a HP 10B when you first get it.

Hello yellow! Glad you are liking the app. As for telling people about the 10bii+ upgrade, it is the first line of the app description in the store: "In-App Upgrade: 10bii+ Features (Bonds, Breakeven, Depreciation, Trig, Probabilities) available!" Enjoy!
