Unity announced a new fee structure today, and developers are none too happy. “We are introducing a Unity Runtime Fee that is based upon each time a qualifying game is downloaded by an end user,” the company wrote in a blog post announcing the change. “We chose this because each time a game is downloaded, the Unity Runtime is also installed.” The new per-install fees are set to kick in on January 1, 2024.

The company says developers will be charged for installations after passing both a minimum revenue threshold from the last 12 months and a minimum lifetime install count. The exact fees will vary depending on which plan they use. Unity Personal and Unity Plus subscribers will pay $0.20 per install after reaching $200,000 in revenue from the past 12 months and 200,000 lifetime installs. Meanwhile, after hitting $1 million in revenue in the last 12 months and one million lifetime installs, Unity Pro members’ fees start at $0.15 per install, while Unity Enterprise fees start at $0.125 per install.
