price of U4 for permanently usage (without 5% fee)

Like in the title. How much will it cost? I know that engine is free, but games (if I get from them 30,000 $ in quarter) I must pay 5% from income? Right? Is there an option for pay permanently for engine and use without that 5% restriction?

You have to negotiate a custom license: https://www.unrealengine.com/custom-licensing

note that it’s not going to be cheap, it’s going to most likely be around the same amount you would pay for the 5% royalty. It’s mostly for big studios where 5% royalty would end up being much more than you would reasonably expect to pay for licensing (like if it were to amount to over a $1 million)
