Accepted Answer

There is no need to delete VPCs, subnets, security groups, and network ACLs, as they will be the ones that do not incur fees when created.

If the EC2, RDS, etc. that were launched in the VPC are gone, then there would be no billing.

You should check the AWS Cost Explorer screen for charges for a few days.

It is rare to forget to delete EC2 or RDS snapshots, so please make sure they have been deleted.

Answer

VPCs, subnets, route tables, and internet gateways do not have a cost. So, it is ok to leave your default VPC. See: [VPC pricing](https://aws.amazon.com/vpc/pricing/).

You can delete the Default VPC if you want to.
