But there is a catch when you start generating income. There is a royalty associated with it when you cross a certain limit.

[{"selector":"#anim-9f1c1389-5c2c-496d-9621-1260c27c0af2","keyframes":{"opacity":[0,1]},"delay":100,"duration":1700,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-ab323011-73d1-456b-ad7e-b895cb7b4bc1","keyframes":{"opacity":[0,1]},"delay":200,"duration":1400,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-e5a686ac-7ecd-4b86-8739-579ab02c8508","keyframes":{"transform":["translate3d(0px, 159.28633%, 0)","translate3d(0px, 0px, 0)"]},"delay":200,"duration":1400,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

Unreal Engine is totally free for educational purposes and for creating internal projects.

[{"selector":"#anim-adabe1bd-fca3-4036-b9b4-0ffa7d4aa46b","keyframes":{"opacity":[0,1]},"delay":100,"duration":1700,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-0ed2c7db-f7f6-4687-9392-a02547c163e1","keyframes":{"opacity":[0,1]},"delay":200,"duration":1400,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-6e3163e6-09c1-4e8b-a097-45ef06d2b624","keyframes":{"transform":["translate3d(0px, 213.94342%, 0)","translate3d(0px, 0px, 0)"]},"delay":200,"duration":1400,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

Unreal Engine allows you to distribute various commercial projects without incurring any fees from Epic Games.

[{"selector":"#anim-6a34bd48-1ae1-42cb-9137-8102f2868e35","keyframes":{"opacity":[0,1]},"delay":100,"duration":1700,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-3b1dd86c-beff-40cd-8ae3-94d77a0468bc","keyframes":{"opacity":[0,1]},"delay":200,"duration":1400,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-56f96690-0716-486e-ba4a-15d174c1fa42","keyframes":{"transform":["translate3d(0px, 158.13203%, 0)","translate3d(0px, 0px, 0)"]},"delay":200,"duration":1400,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

A royalty of 5% is only required if you distribute a commercial product that uses Unreal Engine code (such as a game)

[{"selector":"#anim-cc980719-a7a1-45cc-8e89-83467276fc38","keyframes":{"opacity":[0,1]},"delay":100,"duration":1700,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-c61942b8-1f2e-45d1-b5f2-065eee820bb1","keyframes":{"opacity":[0,1]},"delay":200,"duration":1400,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-3a70a3a7-bfef-40e7-bc89-22c57d94ac07","keyframes":{"transform":["translate3d(0px, 158.13203%, 0)","translate3d(0px, 0px, 0)"]},"delay":200,"duration":1400,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

The Royalty is only applied if the total revenue generated by the product surpasses $1 million USD.

[{"selector":"#anim-84c2563c-6566-4356-97ef-b02d170796d7","keyframes":{"opacity":[0,1]},"delay":100,"duration":1700,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-8227e034-c39d-4ce1-af3e-a17863507666","keyframes":{"opacity":[0,1]},"delay":200,"duration":1400,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-5957ba4e-346e-49fc-8260-ecabd8445d72","keyframes":{"transform":["translate3d(0px, 159.58128%, 0)","translate3d(0px, 0px, 0)"]},"delay":200,"duration":1400,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

Unreal considers every title as different. So, if you have two games making $600k then you don’t need to pay royalty to Unreal.

[{"selector":"#anim-c796d266-5782-48a7-86ac-2d09bf4d73d5","keyframes":{"opacity":[0,1]},"delay":100,"duration":1700,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-b6913d05-3f54-45cd-9d1b-fe5c9c148b8a","keyframes":{"opacity":[0,1]},"delay":200,"duration":1400,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-ed90c70e-e17b-465d-90bd-dc48c6443246","keyframes":{"transform":["translate3d(0px, 127.29606%, 0)","translate3d(0px, 0px, 0)"]},"delay":200,"duration":1400,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

The royalty agreement Changed on May13,2020 and is applicable for both Unreal engine 4 and 5.

[{"selector":"#anim-eb3a2f05-4330-498e-be24-f7cea97ec1af","keyframes":{"opacity":[0,1]},"delay":100,"duration":1700,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-62abb650-d790-44da-bc72-a9f240114248","keyframes":{"opacity":[0,1]},"delay":200,"duration":1400,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-3a75f25e-f8c3-4320-8e8d-730a2e726204","keyframes":{"transform":["translate3d(0px, 160.30595%, 0)","translate3d(0px, 0px, 0)"]},"delay":200,"duration":1400,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

After the change in Royalty agreement Unreal is cheaper when compared to Unity game engine.

[{"selector":"#anim-77ff56cd-a172-4299-a47e-ade22d5fdfb3","keyframes":{"opacity":[0,1]},"delay":100,"duration":1700,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-1a74374b-4a0e-43c1-86d9-5df91dc65d21","keyframes":{"opacity":[0,1]},"delay":200,"duration":1400,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-ed184c31-84bb-4034-94a4-88aa15daaadd","keyframes":{"transform":["translate3d(0px, 160.30595%, 0)","translate3d(0px, 0px, 0)"]},"delay":200,"duration":1400,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]
