The funding rate dynamically changes so it'd be difficult to predict imo. You've also not said what exchange your using.
If you're after a really rough estimate, I'd say 0.2-0.3% for the opening and closing of positions as well as that amount per day it's open - but this is just what I think I've seen in the past.
Hi Thank you for reading my post and trying to help me that is a good start the Exchange in question is Kraken they mentioned that Trading fees apply when opening *and* closing a position, on top of rollover fees)
