How much is the Polygon fee?

Excuse me, I was wondering if you could help me with a query regarding the Polygon fee. I'm quite interested in understanding the current cost associated with transactions made on the Polygon network. Could you please elaborate on the fee structure, if there's a fixed rate or if it fluctuates? Also, are there any factors that can influence the Polygon fee, and how can users potentially minimize these costs? I'd appreciate your insights on this matter.
