How much is 10,000 credits in Rocket League?

Excuse me, I was wondering if you could help me with a quick conversion. I'm trying to figure out how much real-world value 10,000 credits would represent in Rocket League. Is there a standard exchange rate or is it more fluid based on market conditions? I'm a bit new to the world of in-game currencies and I'm trying to get a handle on their worth. Your insights would be greatly appreciated.
