How much is $500 US in Italy?

Excuse me, could you please clarify something for me? I'm trying to understand the current exchange rate between the United States Dollar and the Euro, which is the currency used in Italy. Specifically, I'm wondering how much 500 US Dollars would be worth in Euros. Is there a straightforward way to calculate this, or would it depend on the current market conditions and the exchange rate at the time of the transaction? I'm hoping to get a rough estimate so I can plan accordingly. Thank you in advance for your help.
