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.
1. Windows Built-in Calculator App
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:
- Standard: This is the default mode in the Windows calculator app that performs basic mathematical calculations like addition, subtraction, multiplication, power, division, and more.
- Scientific: In this mode, you can take the exponential of a number, take its modulus, and while performing these calculations, directly use terms like pie (π) and Euler’s number(e). In addition, you can perform trigonometric and algebraic calculations within this mode including all basic calculations offered in Standard mode.
- Graphing: Use this mode to draw graphs of functions. In this mode, you can enter a mathematical function and it will plot a graph for you. Its graphing capabilities to plot complex functions will genuinely amaze you if you haven’t yet tried it.
- Programmer Mode: It allows you to convert values into various number systems, including Hexadecimal, Octal, Binary, and Decimal. Additionally, you can perform basic Bitwise operations such as AND, OR, Not, etc.
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.
2. Calc Pro HD
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:
- Converts between eight different number bases.
- Plots graphs for eight equations.
- More than 3000 unit conversions in 19 categories.
- Converts 150+ world currencies.
- Pre-fed 1500 constants for use.
- Financial calculations with over ten worksheets.
- Statistical calculations with eight types of regression analysis.
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.
Download: Calc Pro HD (Free, In-app purchases available)
3. Naturplay
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.
With the Cortana integration, you can say, «Cortana, I want to calculate.» The app will open following your command, and you will be able to dictate to Cortana to perform calculations. As such, if you want a powerful assistant in your homework, be sure to give Naturplay a shot.

5. Sticky Calculator
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.
Download: Sticky Calculator (Free, In-app purchases available)
6. Calculator+
Unlike other apps, Calculator+ comes with more advanced features like differentiation, integration, and simplification. It is free to use and comes in two themes, light and dark. Besides storing the history of your calculations so you can refer back to them later, it also allows you to add new custom functions that you might use frequently.
Furthermore, you can plot graphs, use complex numbers, solve matrices, and perform calculations in bin, oct, and hex modes. In addition, the app contains a good collection of variables, matrix variables, and list variables, and you can use pre-fed math constants for calculations.
With its mathematical, trigonometrical, hyperbolic, and special functions, this calculator will prove to be an invaluable tool when solving math problems.

The developers of this program have imported the Windows 7 calculator perfectly, complete with its familiar scientific and programmer modes, as well as its robust performance.
To install the program, open the .zip file and run the .exe installer inside. Once you’re done, hit the Windows key and you’ll find it under the recently added programs category. Make sure you drag and drop it to your desktop so you don’t lose it!

Quick tip:
Google It
If you’re always on the web like I am, then you might find the quickest way is just to drop question into Google search. If you have Google as your default search engine, then you can put the expression into the search bar at the top of the browser and have it automatically evaluated in the search result.
It lacks the functionality to save numbers in the calculator’s memory, but it’s a quick and easy way to get arithmetic done.
GeoGebra Graphing Calculator
- Quickly plot functions
- Evaluate and visualize results
If you need to quickly plot a graph, Geogebra is the perfect lightweight program to see what a function looks like.
You can also add sliders for variables as well as include lines, circles and distance measurements to help you visualize the 2D space.
If you want to venture even further into Geogebra’s functions, you’ll also find tracing, polygons, conics and function transformations. All of these are quite helpful in visualizing more complex mathematical concepts.
If you just need to get some values out of a function, then you can calculate the outputs on the sidebar in function notation, such as by typing f(30).
The app is free, fast and lightweight, and saves you from pulling out a physical graphing calculator.

Switch the Windows Calculator’s Mode
If you’re looking to switch out your Windows calculator because it doesn’t offer enough functionality, don’t forget that you can switch it to scientific or programmer mode.
On scientific mode, you’ll find the trigonometric functions, logarithms, fractions and roots.
Bonus: Bind Your Favorite Calculators to Keyboard Shortcuts
There’s no need to go hunting on desktop for your calculator just to make a quick calculation, instead, you can bind it to a key press combination so you can open it whenever you need.
Step 1. Right click the desktop shortcut to calculator.
Using a Windows app?
Step 2. Hit Properties.
Step 3. In the shortcut field, but in your preferred key binds. I put CTRL + Shift + G to Geogebra and CTRL + Shift + C to the Windows calculator.
