I'm new to AWS and just hit with a bill of around $120, even though I had about $120 in credits on my account. I thought using the Free Tier would protect me while I learned the ropes. From what I can see, the charges seem to be from data transfer out, public IPv4 address fees, and possibly some EC2 instance costs, plus taxes. It's really frustrating because I thought I had stopped all my resources, but some of them still kept billing. I learned the hard way that stopping isn't the same as terminating, and some resources can keep charging even if you think you're done. I'm reposting here to raise awareness among other newcomers and to seek practical advice. I have a few specific questions: 1) What AWS resources are commonly overlooked that continue to bill? 2) What's your process for ensuring that nothing is still incurring charges? 3) Do you have a checklist for beginners to prevent unexpected costs? 4) Any tips on getting refunds for accidental charges from AWS support?

Good point about monitoring your AWS costs! Using the AWS API can help you keep track of your expenditures more effectively. Consider using third-party tools designed for AWS billing analysis—they can keep tabs on your spending, even in the Free Tier! That way, you'll have alerts set up to prevent surprises down the line.
Understanding AWS billing can feel overwhelming, and getting stung by unexpected charges is definitely part of the learning process. It's well-known that the Free Tier doesn't guarantee free usage; it just offsets costs after you're already hit with them. If you find yourself faced with charges, it's worthwhile to reach out to AWS Support to ask for a refund. While there's no guarantee, some users have had success depending on the situation.
Many newbies face this issue, but it's important to realize that Free Tier provides credits rather than preventing charges. Double-check your regions for resources like NAT gateways and stopped EC2s; they're sneaky culprits in racking up costs. I recommend a thorough cleanup process—check every region in your AWS account, and keep an eye on Billing tools to catch and eliminate any unnecessary charges. And yes, sometimes AWS will refund first-time billing mistakes if you explain the situation well.
You're not alone in this! Many people get caught off-guard by AWS bills, and even with the Free Tier, you need to keep a diligent eye on your usage. Common resources that people forget about include public IP addresses, EBS volumes attached to stopped EC2 instances, and load balancers. It’s wise to regularly check each region and to look at your Billing - Cost Explorer to see where your costs are coming from. Setting a strict budget alert, even if it’s just $1, can help notify you when you’re approaching charges.
