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.

Recent changes:
Improved Cashflows, Stats screen, and Easy Modes to format numbers with grouping symbols for thousands (i.e. "15,000" instead of just "15000").

★★★★★ Nick D8653 · Dec 14, 2021
This is a great financial app - there has been an issue with Google play the past couple of days that have been resolved - don't let this discourage you from using this app - I have been using this for years and once you get used to using it you won't be able to live without it - also, Kenny was a great help and very responsive during the issues with Google play
★☆☆☆☆ Indira Dejarnette · Jun 9, 2021
WT Heck Bought it struggled w Google play till 330am won't download just says refund or install. With each time I click install it wants to rebill. Account checked paid now no app and needed for all day RARE opportunity training told by 2 experts retiring soon to get. There's a free calculator they said could be alt this morning SMH. This could be a hit for hundreds of thousands when people have bad results everyone switches.
★☆☆☆☆ Lloyd Samsonite · Jan 5, 2022
