Best Windows 10 calculator apps

From balancing your finances to graphing out complex equations, it's always handy to have a calculator around. Windows 10 has a calculator built in, but it isn't as powerful as some tools that are dedicated to more advanced work. Here are the best calculator apps available on Windows 10.

Calculator² has been available on Windows devices for a long time. It has a clean interface with just enough color to improve navigation while also utilizing Fluent Design System elements. More important than its design, it's also a versatile calculator featuring scientific, programmer, financial, and basic calculators. It also has a unit and currency converters.

The app is available for free, but the financial calculator and currency converter require you to pay extra. You can download the app on Windows 10, Windows 10 Mobile, and Windows Mixed Reality.

Naturplay Calculator

Naturplay Calculator is an excellent scientific calculator. It centers on natural writing to simplify the process of creating expressions. There are a lot of little touches inside the app that increase its power and usability. For example, it supports JSON and XML parsing for developers and also has an input panel for matric statistics.

The app is available for free on Windows 10, Windows 10 Mobile, HoloLens, and Xbox One.

Calc Pro HD - Calculator

Calc Pro HD - Calculator is the most expensive app on this list, but it's also the most versatile. In addition to standard, scientific, and graphing calculators, the app includes everyday utilities like a tip calculator, loan calculator, and a compound interest worksheet. In my opinion, it earns its price tag.

The app also looks impressive. While it doesn't look like the most modern app in UI design, the graph layout and astronomy caclulator are attractive, which is more important for an app like this.

Calc Pro HD- Calculator is available for $7.99 on Windows 10, Windows 10 Mobile, Xbox One, and HoloLens. If you'd like to try a free version of the app you can, as well, though it only supports five types of calculators.

Wolfram Alpha

Wolfram Alpha isn't a traditional calculator with a grid layout of buttons. Instead, it allows you to type in queries in natural languages, and then it performs the calculation.

I've been a fan of Wolfram Alpha since my early days at university. It's a useful tool for math and science as well as other types of information. I reviewed the app last year, and it hasn't changed much since then. It costs $2.99

Summing things up

The stock Windows 10 calculator is fine for basic calculations, but if you want to do more advanced mathematics, it's worth grabbing a better tool for your work.

Whether you need scientific, graphic, standard, or everyday calculations completed, there are quite a few solid options on Windows 10. If you use one that we missed, let us know in the comments.

  • own both Calc Pro HD/Wolfram Alpha
  • honestly there is no need for these, the default calculator is awesome and so complete / I wish Microsoft also bring the calculator app to android and ios
  • 100%
  • Yeah I agree - the default calculator is good too and, despite the supposed millions of apps on Android, I've struggled to find a decent one to use on my phone.
  • I use Calculator++ on my Android. Very feature complete and useful for math, effective UI. Would still prefer the Windows calculator, since it's so awesome. Miss it from my Windows phone
  • Concur.
  • The windows calculator is useless IMO because is does not support RPN. Calc Pro does. This review is also worthless because it doesn't state which of the reviewed calculator programs do support RPN.
  • I use 42S with RPN....
    Most folks in here don't even know what RPN is!
  • Windows calc, is all that's needed, a cpl of more tweaks, it would be perfect..... No need to pay for apps
  • I agree with other commenters saying Microsoft's own default calculator is great for basically everything except graphing. I think what's really needed is the ability in Windows to keep windows on top of other windows. This is really what's missing from the Windows calculator experience.
  • Right? I was wondering why we don't have that ability that yet. It would be so useful for checking/referring stuff with a single monitor.
  • You should include Microsoft Mathematics (formerly Microsoft Math in this group. It can be used to write and solve equations directly ans it shows the answer step by step. It is a graphing calculator that integrates into Microsoft Office and it is a free download.
  • Love Microsoft calculator and of course Wolfram
  • Windows calculator is pretty good, but I’ve always wondered why they never added a standard desktop (10-key) calculator mode...
  • I call your calculator and raise my Excel.
  • 2 things I miss with all these calculators:
    1. being able to open these apps multiple times in multiple windows
    2. being able to make our own calculators in these apps with easy IFTT blocks.
