You can build in Xamarin without paying any money. What costs money is the IDE, Visual Studio, Professional, or Enterprise edition. What would cost you money if you're building apps for the Apple Store is the Apple developer fee, which is $99 per year. If you release the app to the Play Store, you have to pay $25. But Xamarin's license is free.

My company provided all the licenses that we need to support our use of Xamarin Platform.

There's no licensing cost for Xamarin. Like the rest of .Net, it's open source, but there is a licensing cost if you want to use the IDE. There's a number of different development environments you can use. 

You can use just traditional Visual Studio. I license Visual Studio Professional. It's about a thousand dollars a year and Xamarin comes with it. 

I also license another IDE, which I could run independently. That one is called JetBrains Rider, and it's only about $200 a year. You could do all of your Xamarin development with that if you didn't care to license the other stuff. 

The actual platform itself technically doesn't require anything. If you wanted to download Visual Studio Code, which is a free IDE, and figure out all the plugins to get everything to build and work the way you wanted, you could actually technically develop for free, but I don't think many people do that.

We took the Visual Studio licensing. If you take that license, this product comes with it. 

It might be $400 or $500 per year. We are using the Enterprise version of the software. They might pay per year or per developer. I'm not sure of the exact rate.

The price of the Xamarin Platform is not expensive. However, the price of the solution depends on the application that is made. For example, if you have small applications, it's different from large or enterprise applications.

The cost for us on average is $2,000 to $3,000 for all the projects. This involves starting from scratch until we deploy and package them to the Google Store or Play Store for publishing.

The product is inexpensive.

There is no license, and it is open-sourced. Therefore, there are no hidden fees.

This is an open-source solution, but there is a subscription charge to use the App Center of around $100.

I think the solution is free.

Xamarin Platform is open-source, so it is free to use.

Xamarin is available under several licensing arrangements. Each developer needs one license at least. To access all features, especially the Profiler, you need the highest tier.

Xamarin is open source, so it's free. If you're planning on development within a company, it might require purchasing the commercial version.

Xamarin is free. There is no license unless you go for some high-end enterprise features. Other than that, everything's free.

It is a free platform.

Xamarin Platform is a free open-source solution.

There is no license fee because the solution is open-source.

This is an open-source solution and there are no costs on the Xamarin side. If you're using it with iOS then you need to purchase a membership which is about USD$100 per year. 

Xamarin Platform is open-source, but there are fees for deployment, the API Store and Play Store, and using third-party libraries.

There is no requirement for a license. It is available for free as an open-source product.

If you plan smartly enough I think you will save some bucks for sure. You don’t need different native developers for each platform as Xamarin comes with cross-platform development so that’s an advantage.

In most cases, it is sufficient to have free/community license. But if you plan to seriously develop production-level, highly polished apps, you need to use Xamarin.Profiler and the professional or enterprise license.

This is a free product, so there is zero investment on licenses and IDE.

Licensing and pricing have changed, as the product moved to Microsoft. Before that, it was fairly complex: $800 per developer place, for one platform only.

Xamarin is free, or comes with Visual Studio. Therefore, it is very profitable.

For personal use, the Community Edition is free. If someone is a freelancer he can easily use the free edition.
