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 HP 10bII Financial Calculator, the 10bii Financial Calculator app 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. The 10bii Financial Calculator's keypad has been specially designed to be easy to use and easy to see. 

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 Flows, lets you see the stored values of all of your memory registers in one easy view, graphs your statistical series, and lets you type in whole equations for easy review and one-touch evaluation.

With the 10bii Financial Calculator, you can:

Get answers to common financial questions WITHOUT having to know how to use a financial calculator!  With the 10bii Financial Calculator's Easy Modes, answer a few simple questions worded in plain language (rather than Financial-ese) and find out just how much you'll save with that refi, how much you'll have at retirement, how long it'll take you to save up for that big purchase and more.  Now with 12 Easy Modes!

Easily enter and see diagrams for 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.

Enter and analyze statistical data points, and see graphs based upon the values you enter. 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 powerful enough for the professional but accessible enough for everyone.

### 1/5 — Mauvais

*2026-02-12, version 4.12*

Trop dur wallah

### 5/5 — Best Financial calculator

*2025-12-25, version 4.12*

Great app that is easy to use and worth its cost. Never had issues with it & helps with investing.

### 5/5 — The power of knowledge

*2025-06-09*

This calculator is an awesome tool for prospecting.  I’ve used the 10b for 35 years. 

As a mortgage professional, I have been asked thousands of math questions. What’s my payment ?  What interest rate am I paying now? If I shorten my term how much can I borrow?  Amortization schedules, or simply cost per thousand dollars borrowed.   It allows me to text the amortization information to my perspective clients, thus giving me their cell number and building my reputation!

### 5/5 — Perfect for HP 10b fans

*2025-03-30*

I still have my old HP 10b from college, and it's awesome. I need one to take with me all the time, so I bought this. I was hesitant, since the reviews for the actual HP 10bii+ are mostly negative.

Turns out this app is great. I highly recommend it.

### 1/5 — Atrocious UI

*2025-03-27, version 4.10*

This is standard math, the expectation form an $7 app is to make its easy for a lay person to use and not have to use youtube videos to learn how to get an amortization schedule.  I could have done that with Excel PMT. I wanted a lazy solution but this isn’t it, i wish i had not spent the money

### 1/5 — Not the same as 10II

*2025-03-19*

I wanted to hit the same keystrokes on this calculator as I do on my real calculator. That doesn’t work. It keeps open up dialog boxes that have more questions than the single input I was looking to put in. I am sure if I spent time I can figure this out, but I really just mindlessly wanted to hit the same keystrokes because my calculator was not close by. I can’t believe I paid for this when I thought it was going to be the same. How do I get my money back

### 1/5 — Baloney ahh app

*2025-02-07, version 4.10*

The free financial calculator in the App Store is so much better and if you’re in college, it will be the exact same as the calculator your professor will use. Don’t waste your precious money on this app unless you are an experienced finance calculator expert. Just get the free one lil bro ✌️

### 5/5 — Small new bug

*2025-01-21, version 4.10*

Love this app and use it every day!  A new bug came in on the last update though on something small - when you try to add a percentage to a number it only adds the percentage number, not the percentage amount.  Example 100+12% is 112, but the result shown is 100.12

### 5/5 — Excellent and effective

*2024-12-27*

For my work, I have a financial calculator in the mobile program I use which is great at illustrating how much growth occurs over a period of time at higher rates of return, but this one is my go to app when speaking with business owners and initial meetings with prospective clients to illustrate the impact of inflation and simple savings and investing strategies. Simple and effective. Thank you.

### 5/5 — Excellent! Second to none!

*2024-10-28*

I’ve used this app for quite a while, and I found it to be full of features that you would expect, as well as features you would not expect, such as full amortization tables. This app is very well done.
