I currently have a long-term gold and silver position by holding GLD and SLV equities on 2x margin with TastyWorks. The funding rate is 8% for the margin.

I'm curious if it would be better to sell my equities and replace it with SPRE, which is a smaller size precious metals futures contract they offer with a tick size of 0.01 x 100.

The problem is I don't know how to calculate if it would be cheaper for me to hold my positions through futures contracts long-term rather than holding stocks. Are there funding rates for futures contracts held overnight where you either pay or get paid depending on the number of long and short positions? Or would the only fees be calculated when rolling over each month?

You would need Full Margin if holding any Futures contract and be aware of the LTD
