About Paying

If I released a game using unreal engine and earning more than 3000$ in one calendar quarter, I’m supposed to pay 5% of the money I get just in that 3 months or 5% of all the money I get since the game released?

You should be paying on a quarterly basis, so you should have paid the 5% for the previous quarter at the end of the previous quarter. So functionally, each payment should be for just the current quarter. In addition, you do not owe royalties on the first $3,000 every quarter. So each quarter, you would be paying (Revenue - $3,000)*(5%)

Get it. Thanks!
