The days of high school algebra may be a distant memory, but that doesn’t mean that a reliable calculator can’t help you as a businessman. Whether you’re a small business owner trying to balance your budget or a home office worker figuring out your self-employment taxes, having a good calculator handy can speed up the process. And although the technology behind portable calculators is over 50 years old, today’s devices run the gamut between options designed for basic calculations and more advanced models with a built-in printer and color LCD display.

To find the best calculator, it’s important to consider how intuitive its functions are, how affordable the model in question is, and how historically reliable the manufacturer’s products have been, along with other determining factors. With that in mind, here are the best calculators for you.

Final verdict

The Texas Instruments TI-30X IIS (see on Amazon) is the best overall calculator for several reasons. With an easy-to-use interface and a large two-line display, it has enough power to handle larger calculations while still maintaining the kind of functionality people expect from Texas Instruments. Combine all of that with a reasonable price tag and you’ve got a great calculator that can handle everything from easy sales transactions to complicated tax considerations.

### What type of calculator is right for me?

Calculators today can handle a wide variety of calculations, but sometimes you just need a simple calculator to work. If you only need to calculate basic addition, subtraction, division, and multiplication (with some consideration for decimal points), then you will probably be okay with a regular calculator. By the time you need to solve X or use data points to plot a graph, you will need a more advanced calculator.

### What is the difference between a calculator, scientific calculator and graphing calculator?

Although every calculator can handle basic mathematical equations, scientific and graphing calculators are generally more advanced than regular calculators. For example, a scientific calculator provides functions that can solve algebraic equations, such as finding exponents, roots, and logarithmic equations. Conversely, a graphing calculator can do all of these things, with the ability to plot a graph on its screen, creating different types of graphs with just a few buttons.

### Why would I need a calculator with printer?

If you need to do financial calculations or work in the financial industry, a printable calculator can be useful to avoid having to create long spreadsheets for a single equation. Printable calculators have the innate ability to let you review your calculations whenever you want.

Traditional calculators have screens that can display a few lines at a time, but a printing calculator creates a receipt for your entire chain of calculations. Rather than having to redo your work, you can read what was printed to verify it. When you are finished, you can remove the printed paper from the calculator and store it with your records.

### Why are some calculators much more expensive than others?

As with most technology, calculators generally get more expensive as features like more computing power, high-resolution color displays, and the ability to code and implement your own apps are added. This is why a simple calculator can cost less than \$ 10, while a graphing calculator costs around \$ 100.
