How much VP does a $5 gift card give?

I'm curious, could you please elaborate on how many virtual points, or VPs, one can acquire from a $5 gift card? It's important to understand the exchange rate or value associated with these virtual rewards, as they may vary depending on the platform or program in question. Is there a standard rate that applies across the board, or does it differ for different services? I'd appreciate any clarification you can provide on this matter.
