HP 10BII+ Financial Calculator Review + Guide

The decision to purchase a financial calculator is not an easy one.

For one, financial calculators are pricey, so you need to seek value for your money.

Also, you need to ensure the calculator you choose caters to your specific needs — for instance, students who are due for CFA exams. Keep in mind that only a few calculators are allowed in CFA exam rooms.

And finally, durability is a priority. Calculators fall all the time not to mention the accidental coffee spills. You need a calculator that is manufactured with all these aspects in mind.

So, whether you are looking to buy your first financial calculator or you want an upgrade, this is the right place to be.

Speaking of upgrades;

Hewlett Packard recently upgraded their HP 10BII calculator to a more advanced HP HP 10BII+ Financial Calculator.

About HP 10BII+ Financial Calculator

HP 10BII+ is the best financial calculator for a beginner. It is simple to use and just complex enough to do advanced math.

We love that this bad boy has over 170 built-in functions. And even though you can’t have the HP 10BII+ in a CFA class, it is accepted for AP, PSAT/NMSQT, and SAT exams.

In a nutshell, the HP 10BII+ appeals to students, real estate agents, accountants and pretty much anyone who works in finance.

Let us have a look at the upgrades applied to the HP 10BII+.

Differences Between the HP 10BII and the HP10BII+

As we have seen with other Financial Calculators, upgrades don’t affect the core functions of the calculator.

The HP 10BII+ is no different.

All the core functions remain the same. However, the HP 10BII+ carries some phenomenal upgrades. They include:

  • Probability Distribution Calculations
  • Depreciation
  • Bonds
  • Expanded Statistics Capabilities

Perhaps the best way to detail the HP 10BII+ is to break down its features.

Features of HP 10BII+

Basic Mathematics

The upgraded HP 10BII+ features all the essential math functions. Besides, there are advanced features, including:

  • Trigonometric functions inclusive of Sine, Cosine, Tangent, and their Inverses.
  • Pi Constant (3.141592653589793)
  • Permutations and Combinations
  • Hyperbolic functions plus their Inverses
  • Radian and Degrees modes but without Angle Conversions

Dedicated Buttons

One of the most outstanding features of this calculator is the array of Dedicated Buttons to make your calculations fast and efficient.

Here are our picks for the best-dedicated buttons on this bad boy.

  • Amortization and Time Value of Money capability. These features are invaluable for people working in finance and real estate. This is due to their quick loan and mortgage calculation capabilities.
  • Cash Flow Calculations. There is no Cash Flow without IRR, NVP, and NFV. With the HP 10BII+, you can store up to 45 Data Points with no frequency limitations.
  • Breakeven Point Analysis. These calculations are integral in determining profits against the cost of running a business.
  • Depreciation Functions. You will enjoy functions like Straight Line, Sum of the Years Digits, and Declining Balance. However, note that the depreciation functions only work in whole years.
  • Statistical Data Entry. According to the manual, HP 10BII+ will allow you to store, edit, and review up to 45 Data Points. Also, you can choose from 6 Regressions (Linear, Logarithmic, Exponential, Power, Exponent, and Inverse). If you have no idea which regression is ideal, HP 10BII+ offers a “Best Fit” (Regression 0) option.
  • Normal, Inverse Normal, Students’ and Inverse Students’ Distribution capabilities. Students with extended, cumbersome probability tables don’t have to go through the same steps every time. With HP 10BII+’s lower tail normal distribution and Students’ t distribution CDF capabilities plus their inverses, students can work their probabilities fast and easy.

That’s not all.

HP 10BII+ allows you to switch between Chain and Algebraic modes.

Last but not least, you will see a “Last Answer” feature. At first, this can be confusing. But all it means is the value of the last calculation, which is in line with HP 10 BII+’s continuous memory.

More of this below.

Memory Capacity

The HP 10BII+ has 22 memory registers. This feature is a significant upgrade from the previous ten memory slots of the HP 10BII

Further, this bad boy has a continuous memory. For this reason, the calculator remembers the value of the last computations. This is regardless of whether or not it was switched off.

Quite cool, huh?

Moreover, the HP 10BII+ saves 30 slots for Cash Flow and Data Points. Consequently, you will have 15 slots for Cash Flow and 15 slots for Data Points.

The manual says you can store 45 Cash Flows and 45 Data Flows. However, once the 30 slots are full, you can only add Data Flows, and you won’t be able to review them.

You will love that the HP 10BII+ has 12 characters on the LCD. Most financial calculators feature ten characters.

Other Features

The HP 10BII+ has a prettier keyboard. I find the blue-shifted functions brighter and more apparent.

Additionally, the keys are easy to push with perfect tactility. You will rarely miss keystrokes.

Further, HP 10BII+ carries 2 CR2032 batteries. According to the manual, these batteries are expected to last up to a year with daily usage.

Moreover, the HP 10BII+ features an Auto Shut Down feature. This feature shuts off the calculator if it goes for 5 minutes without contact.

If you are into Date-Related Calculations, you are in luck. HP 10BII+ supports both the US Date Format (mm.dd.yyyy) and the British Date Format (dd.mm.yyyy).

And finally, this calculator is sturdy and durable. Don’t be too worried about steep falls or random spills. It will clean up pretty thoroughly and work just as well.

Pros & Cons


  • 170+ in-built features
  • 10 more advanced financial and statistical calculations
  • 12 characters on the LCD
  • Continuous memory


  • No RPN
  • You can’t use it for CFA exams


The HP 10BII+ is a better calculator than its predecessor. We love all the additional calculations. Also, the dedicated keys make calculations go that much faster.
