Amazon Web Services (AWS) has a free plan; paid plans are priced by quote, but hidden costs like implementation and support still add to the total as of November 2026. Key hidden costs: phantom charges for deleted/unused resources, data egress / network transfer costs, ec2 t-series unlimited mode burst credits. Verified from 1 sources by CostBench.

Hidden Costs Breakdown

Phantom Charges for Deleted/Unused Resources

critical overage

Users report being charged for resources they deleted or never provisioned. VPCs, public IPs, and other infrastructure components can continue generating charges even after deletion or when no services are running. AWS sometimes auto-provisions resources (like WAF distributions) that cannot be removed, trapping customers in ongoing charges.

They have been charging me for VPCs usage.I deleted those and then those were regenerated. Once I blocked all of them I got charged for Public IPs reserved. I deleted those and they keep charging me.

They are forcing WAF into customers and force you to pay... YOU CAN'T REMOVE THE Distribution to prevent unwanted charges!

Data Egress / Network Transfer Costs

high overage

AWS charges significant fees for data transfer out of their network, which are easy to underestimate. Community analysis of Kafka clusters on AWS found network costs alone could add $103,000/year even for small 35MB/s workloads. Inter-zone networking fees on a 3 AZ Kafka cluster were cited at $14,765/month.

And I haven't even begun to mention the network costs, which can cost an extra $103,000 a year just in this miniscule 35MB/s example.

reddit · 2025-04-21
An equivalent 3 AZ Open Source Kafka cluster would cost over $20,252/month, with the inter-zone networking fees alone costing almost five times as much as the total infrastructure costs for WarpStream ($14,765 vs. $2,961).

EC2 T-Series Unlimited Mode Burst Credits

high overage

EC2 T-series instances (t2/t3) running in 'unlimited' mode charge $0.05/vCPU-hour for burst credits above the baseline. A t3.nano running at full CPU in unlimited mode costs $0.1052/hour — 5x more than a t3.small and 20x more than the baseline non-unlimited rate. This can make burstable instances more expensive than larger fixed-performance instances.

reddit · 2025-05-13
Burst credits for t2 and t3 cost $0.05/vCPU-hour... t3.nano has a baseline cost of $0.0052/on-demand hour. If you max out its two vCPUs in unlimited mode, then you pay 0.0052 + 0.05 * 2 = $0.1052/hour. That's 5 times as expensive as paying for a t3.small, and 20 times as expensive as the non-unlimited t3.nano was.

EBS Storage Costs for Data-Intensive Workloads

high overage

AWS EBS (Elastic Block Store) storage is significantly more expensive than comparable bare-metal storage. For data-intensive workloads like Kafka, st1 HDD storage costs $45/TB/month in the cheapest us-east region ($54/TB in Frankfurt). A small 6-broker Kafka cluster needing 130TB could cost $70,200/year in storage alone — 32x more than equivalent bare-metal (source dated Sep 2024).

reddit · 2024-09-29
`st1s` cost 0.045$ per GB of provisioned (not used) storage each month. That's $45 per TB per month... We will need to provision 130TB. That's: $188 a day, $5850 a month, $70,200 a year

S3 Tables Premium Storage & Compaction Fees

medium overage

S3 Tables (AWS's managed Iceberg service) costs 15% more than standard S3 storage and adds a new compaction charge at $0.05/GiB processed plus $0.004/1000 objects. For 1TB of new data ingested monthly, compaction alone adds a one-time $51.20 fee. Total cost is approximately 37% more expensive than standard S3 (source dated Dec 2024).

reddit · 2024-12-05
Storage Costs - these are 15% higher than Standard S3... Compaction - a completely new Tables-only cost, charged at both GiB-processed and object count. $0.004 per 1000 objects processed. $0.05 per GiB processed

Savings Plans Complexity & Incorrect Charges

high addon

AWS Savings Plans can result in unexpected charges. Users report being charged 200% of instance cost for unused Savings Plans coverage on instance types they believed were not covered (such as T-series RDS instances). Resolving billing disputes is extremely difficult with no effective escalation path.

trustpilot · 2026-05-08
their staff mentioned T-series instances are not covered by the saving plans. Yet, they charged, 200% of the instance cost (fixed hourly rental, not on demand, not by usage).

Support Plan Costs

high support

trustpilot · 2026-05-06
the billing support ticket I lodged has sat for 65 days without even being assigned. It's impossible to reach AWS (online chat times out, no phone number to call)

trustpilot · 2026-06-25
HI ! Its been more than a week and my support case 178184788100483 is still not assigned nor fixed

Lambda + API Gateway Hidden Overhead

medium overage

Serverless architectures using Lambda are not truly free at idle. AWS KMS and API Gateway incur charges even when no requests are processed. Lambda also charges per RAM×time, per concurrent execution, and re-execution charges apply when timeouts occur.

hn · 2022-06-09
If you use AWS Lambdas do implement something like an HTTP endpoint, you still need to pay for stuff like AWS KMS and API Gateway even if no client hits you with a request... Above free tier AWS Lambdas are terribly expensive when compared with EC2 alone. You're charged per RAM*time, you're charged per concurrent execution, and if your Lambda times out you have to pay for the re-execution.
