5% of zero is zero.

You will not owe royalties if you do not receive any revenue whatsoever. Please note, however, that revenue is broader than just the purchase price of the app. Revenue includes ad revenue, in-app purchases, etc. So even if your app is free, if you receive revenue in any form attributable to the app, you will owe a royalty (except in specific cases set forth in the EULA). Please see Section 5 of the EULA for more detail.
