How much is an Everest permit?

I'm curious to know, what's the current price tag on an Everest permit? It's such a prestigious and challenging climb, I imagine it doesn't come cheap. Is the cost relatively stable, or does it fluctuate based on demand and other factors? Are there any additional expenses or fees that climbers need to be aware of when preparing for their Everest expedition? I'd love to hear your insights on the financial aspect of scaling the world's tallest peak.
