That's low compared to the old one which was something like $3k for one platform, $5k for multiple.
If you cannot make $215/month with your software, how can you pay anyone a salary?
If you are non-professional, why not use the open source edition and add value with support?
As stated in other reply, open source option not an option as it states I can't publish it in app stores.

You would mostly need the commercial version only for mobile deployment due to LGPL having issues with static linking. Support for natively compiled Qt Quick is also a bonus.
"You must purchase a Qt Commercial Developer License from us or from one of our authorized resellers before you start developing commercial software. The Qt Commercial Developer License does not allow the incorporation of code developed with the Qt GNU LGPL v. 2.1 or GNU GPL v. 3.0 license versions into a commercial product."
Basically, you have to choose LGPL or commercial before you start your project. You can only transition from commercial to LGPL, not LGPL to commercial.
They do that to prevent specifically the thing you're suggesting, though they're probably aiming it more at large companies with many developers, so those guys don't just buy 1 license.
It might be me as I am not a native English speaker but I think "non-commercial" is more accurate than "non-professional" as people can write free software rather professionally and they often do.
