A team creates a game with UDK that they intend to sell. After six months of development, they release the game through digital distribution and they earn €15,000 in the first calendar quarter after release. Their use of UDK during development requires no fee. After earning €15,000, they would be required to pay Epic €2,500 (€0 on the first €5,000 in revenue, and €2,500 on the next €10,000 in revenue). On subsequent revenue, they are required to pay the 25% royalty.
