Editor's choice

HP 12C Platinum

  • 1-Line-by-10-Character Display
  • Over 130 built-in Functions
  • RPN & Algebraic Data Entry
  • Keystroke Programming, up to 400 Steps
  • Carrying Case & Long-Life Battery

It’s impressive that a calculator can be in the market 30 years after its first production.

Maybe it’s because of its durability, or it is its excellent battery life. Either way, HP 12C is here to stay.

From actuaries to money managers, auditors, product managers, and many others, one calculator lies on their desks, and they all love it the way it is.

Reverse Polish Notation (RPN)

This feature cuts the calculation time by half. It prevents double entry of sign such that if you need the answer to 5 + 7, you just type 5 Enter 7 +so you won’t use the equal sign. This reduces your time on the keypad thus saving you time when handling many calculations.

As we say in business, time is money and a calculator that puts value in time is worth any computer app. This calculator also has an algebraic entry system with parentheses.

Over 100 Financial Functions

HP 12C can handle up to 80 cash flows thanks to the memory function. The same memory can handle up to 400 steps for the 130 functions. It provides you with a nice mix of finance, business, and statistics allowing you to solve all types of math problems in your sector.

This includes time-value-of-money math and creation of amortization schedules with the help of NPV and IRR. It can also store your custom programs for future calculations of cumbersome problems.


You have a one-line 10-digit display. It is on an adjustable contrast LCD which allows you to change the brightness to suit the exterior conditions.

Being able to adjust contrast eliminates eye strain if you are in a low lit environment. It also allows you to read the results fast and smooth with a light setting that suits your eyes.

Build Quality and Battery Life

One of the reasons this calculator has managed to stay in the market for so long is its shock resistance. Whether you work in the office or you spend your time in the field, you will at one time drop your calculator on the floor.

If it is a concrete floor, you can end up with a cracked screen or jammed keys. But not with the HP 12C. It is rigorously tested for falls that’s why you will spot it in just about any environment.

Looking at the battery life, HP 12C is powered by one CR2032 battery. It continues to provide similar long-term performance. Some users indicate they have not replaced their batteries for over a decade. It goes on to say the kind of reliability you can only get on HP 12C.

Best Accounting Calculator – Buyer’s Guide

An accounting calculator is always a valuable investment. Here are some notes to remember as you choose an accounting calculator for your needs.

Advantages of an Accounting Calculator

Geared towards finance problems. Apart from the basic math computations, these calculators also have additional features that help to solve financial problems. These can be such problems involving tax computations, discounted cash flows, interest rates, etc.

They are affordable. Accounting calculators do not have to carry complex functions like graphing capabilities. This brings down their cost which is ideal when you want to run a profitable business without investing heavily in equipment.

Easy to Use. The menus and display of these calculators are straightforward to use and see. They have color-coded keys with large LCDs where entries include the operation symbol. You’ll be able to get accurate answers instead of writing down numbers and doing the calculations in your head.

Portable Designs. These calculators are generally compact. You’ll not have to invest in many pieces if you need to use one in the office and another at home. This is because they can easily be carried to different locations.

Disadvantages of Accounting Calculators

Over-dependence on calculators including accounting ones seems to be a problem that spans throughout all sectors.

Using a calculator for all your calculations can create embarrassing situations where you are unable to solve simple math without a calculator.

Important Questions before buying an Accounting Calculator

How do you use an Accounting Calculator? Using an accounting calculator is incredibly simplified when you follow its instructions. Most of the keys are color-coded to allow memorizing of where specific functions are dialed in.

Accounting keys like Margin, TAX, Currency Conversion, and Cost/Sell are found on the upper side of the calculator.

White keys in many calculators represent the primary functions while the other colors blue/green indicates alternative functions.

How to Clear an Accounting Calculator? If your calculator does not have any stored entries, pressing the C button will clear the operation in progress. The CE key clears the screen but will not clear entries stored in the calculator’s memory. The MC clears anything stored in memory.

How do you set the tax rate on an accounting calculator? If you do work that constantly involves inputting tax rates, it will require that you know how to apply the current tax rate to save time and keystrokes.

In this case, we are going to use a Casio Accounting calculator to set the tax rate. If you want to add 12% tax rate:

  • Press down the AC key and press and hold for two seconds the % key which has the word SET
  • Now enter 0 and press the AC key
  • You’ve entered the tax rate, and you can add or subtract this tax rate using the TAX+ and TAX- keys

Does size matter? Your accounting calculator will be used on a daily basis. It is imperative that it is the right size for easy carrying around. It should also feel sturdy in your hands. You don’t want to keep dropping it if it’s too large.

Types of accounting Calculators

Accounting Present and Future Value Calculator. These are financial calculators that allow you to enter values for calculating money problems involving time. They are useful when computing investment problems like how much money you’ll have in the bank after five years at the current interest rate. The calculator allows you to compute the answer by inputting the different terms.

Book Value Accounting Calculators. Book value is the current value of a company after taking into account depreciation of assets and liabilities. This value appears in balance sheets but has to be computed in a series of actions. Book value calculations are provided by computer programs more so in Excel.

How to choose accounting calculator // Accounting calculator buyer’ guide

Margin Calculator. These are important calculators associated with Forex trading. They are trading tools that help compute the currency value since currencies come in pairs. They help users determine the course of action regarding their investment.

Accounting Calculator vs. Excel

The question to use accounting calculators or Excel is always a debate.

Accounting calculators are very easy to navigate. They are very handy as they are small and portable. It’s not like finding room for your laptop when going to work every day. An accounting calculator is excellent only to a certain degree.

If you work in a busy accounting firm, you’ll find yourself using both Excel and your financial calculator. Excel sheets save time when you have to analyze books of large organizations. These spreadsheets automate calculations, simplify tasks, and improve accuracy levels.

Excel spreadsheets are indispensable for budgeting, data entry, and financial forecasting. An accounting calculator cannot take the place of Excel spreadsheets, but Excel can take over the work of an accounting calculator. Only that, performing simple calculations is better on an accounting calculator.


Accounting calculators are crafted to handle financial functions. The question about which model works great comes down to your budget and preference. The accounting calculators on our list are beneficial to accountants, actuaries, business workers, and individuals who need help with their finances.

If you are looking for an accounting calculator on a budget, or you are content with a paperless printing model, you’ll find our models satisfactory.

Here, you’ll get a calculator that can help you be better in money matters. After all, we interact with money every day.
