How much does it cost to create ERC20?

I'm just getting started in the crypto world and I'm really interested in ERC20 tokens. Could you tell me, how much does it typically cost to create an ERC20 token? I've heard it can vary depending on a number of factors, but I'd like to get a general ballpark figure. Is it something that can be done cheaply, or does it require a significant investment? Also, are there any hidden costs or ongoing expenses that I should be aware of? I'm just trying to get a better understanding of the financial commitment involved in this process.
