Are There Charges for Using Elastic IPs with EC2?

Yes, Elastic IPs will charge you even if you're not using them. And just to clarify, automatically assigned public IPv4s cost the same, so you'll pay for any public IPv4 you have reserved.

All Elastic IP addresses incur a charge, whether they're in use or just allocated. It's best to check the official docs for more specifics. Don't forget that starting February 2024, any resource with a public IP, elastic or ephemeral, will also be charged.

That's correct! Elastic IPs have been charged since last year, and you’ll get charged no matter if they're in use or sitting idle.

Yes, you'll incur charges for every Elastic IP allocated to your account, regardless of whether it's attached to an instance or not. So even if you're not actively using it, if it's allocated, you're paying for it.

Yup, both Elastic IPs and regular public IPs come with costs. It's a good idea to keep track of what you have allocated to avoid surprise charges.
