A good calculator comes in handy when you need to do complex equations, and our picks are the best calculator apps there are on Windows.

When calculations get hard to solve in your head, a fully featured calculator in Windows can be a lifesaver. These days, you can find hundreds of apps that can completely replace your pocket calculator.

Some apps may be limited to basic functions, but the advanced ones with features matching your scientific calculator will undoubtedly impress you. But choosing between too many options may be overwhelming.

We have listed the six best calculator apps you can use on Windows to narrow down your choices.

Before you begin looking at third-party calculator apps, you should take a look at the default Windows calculator app that comes built-in with the operating system.

The default Windows calculator has four different modes: Standard, Scientific, Graphing, and Programmer. Here is what each mode has to offer:

In addition to these basic modes, you can also perform date calculations and unit conversions for as many quantities as you can imagine, such as Currency, Volume, Temperature, Energy, and so on.

The built-in calculator can't do the job for you by any chance? There are plenty of other options you can try. Here are a few of them.

You should choose Calc Pro HD as your second choice if you want to enjoy all the basic Windows calculators' features with some additional perks that aren't available in the built-in app.

Here are some highlights of what Calc Pro HD can do besides Scientific and Standard calculations:

In addition to offering more flexibility in calculations, this calculator integrates with Cortana. That is, you can dictate Cortana to do the math for you without any hassle. This would be the perfect alternative to the Windows built-in calculator and the ideal replacement for a pocket calculator.

You can only perform standard and scientific calculations in the free version of Calc Pro HD. To access all other features, you'll have to subscribe to its premium plan.

Naturplay, another free-to-use calculator for Windows, provides quick real-time calculations of formulas as you type. When calculating long-form mathematical expressions, this can prove helpful.

The display feels like you are writing the calculations by hand, and it will significantly reduce calculation time since you won't have to press equal every time you want the results. Moreover, you can zoom into the calculation panel and save the calculation as an image to print or use later.

When it comes to interactive displays, Super Calculator is the best. It is the best choice for solving long expressions and it allows you to edit the expression anywhere, removing the hassle of typing the whole expression again - which cuts down operation time.

Though it may not have as many functions as other calculators on the list, the interface is easy to use. Like Naturplay, the Super Calculator is free to download from the Microsoft Store on Windows, and you can save and print your calculations.

Sticky Calculator combines a calculator and a memo tool into one. Unlike other apps, there is no Numpad to enter numbers. Instead, you can type in your expression via the keyboard and the calculator will automatically solve it and display the result.

This app offers the ability to write notes while carrying out calculations, which places it above all other apps on the list. Sending rough calculations full of instructions to your friend will be an easy task with the Sticky Calculator. Last but not least, the app is free to download.

The downside to using this app is that you have to input the formula term correctly. Taking the square root of a number requires adding sqrt(Number). This will not work if you input the same expression as square root (number). The same applies to other formulas.

Hopefully, one of the apps on this list will perfectly suit your needs. In case nothing seems right for you, you can explore the Microsoft Store, where you'll find calculator apps galore. It is not necessary to buy the premium versions; free versions will suffice too.

If you don't want to download the apps and start calculating right away, there are many handy online calculators like Good Calculators, Desmos Graphing Calculators, Symbolab, WolframAlpha, and more.
