Billing, Pricing & Support Plans
AWS uses pay-as-you-go pricing with volume discounts and commitment-based savings. The five support plans range from free Basic to $15,000/month Enterprise with a dedicated Technical Account Manager (TAM). AWS Organizations consolidates billing across accounts and shares reserved instance discounts, while Service Control Policies enforce permission guardrails.
1. AWS Pricing Principles
Four core principles:
- Pay-as-you-go — No contracts, no minimum commitments for most services
- Save when you commit — Lock in 1 or 3 year commitments for significant discounts
- Pay less by using more — Volume tiers; the more you use, the lower the per-unit cost
- Benefit from AWS scale — AWS continuously reduces prices as it grows; customers benefit automatically
2. AWS Free Tier
Three types of free tier offerings:
| Type | Duration | Examples |
|---|---|---|
| 12 months free | First 12 months after account creation | 750 hrs/mo EC2 t2/t3.micro, 5 GB S3 Standard |
| Always free | No expiration | 1M Lambda requests/mo, 25 GB DynamoDB storage, 50 GB CloudFront data |
| Trials | Short-term free trial | SageMaker, Redshift, Inspector |
3. EC2 Purchasing Options
| Option | Max Savings | Commitment | Interruption Risk | Best For |
|---|---|---|---|---|
| On-Demand | 0% | None | None | Unpredictable workloads, dev/test, first-time use |
| Reserved — Standard | Up to 72% | 1 or 3 yr | None | Steady-state predictable workloads |
| Reserved — Convertible | Up to 54% | 1 or 3 yr | None | When instance type may change |
| Compute Savings Plans | Up to 66% | 1 or 3 yr ($/hr) | None | Flexible across instance family, size, region, OS |
| Spot Instances | Up to 90% | None | Yes — 2-min warning | Batch jobs, data analysis, fault-tolerant workloads |
| Dedicated Hosts | Varies | Optional 1/3 yr | None | Server-bound licenses (Oracle, Windows), compliance |
| Dedicated Instances | Varies | On-Demand or RI | None | Physical hardware isolation from other customers |
4. Pricing for Key Services
| Service | Pricing Dimensions |
|---|---|
| EC2 | Instance hours, instance type, OS, Region, purchasing model |
| S3 | Storage GB-months, number of requests, data transfer out, replication |
| Lambda | Number of requests + duration in GB-seconds |
| RDS | Instance hours, storage GB, I/O requests, data transfer, Multi-AZ surcharge |
| CloudFront | Data transfer out to internet, number of HTTP requests, Region |
| DynamoDB | Read/write capacity units or on-demand requests, storage GB, global tables replication |
Data transfer pricing note: Data transfer into AWS is generally free. Data transfer out of AWS to the internet incurs charges. Transfer between services within the same Region is often free or low cost.
5. AWS Support Plans
| Plan | Price | Contacts | Response: Production Down | Response: Business Critical | TAM |
|---|---|---|---|---|---|
| Basic | Free | 1 | No phone/email support | No | No |

| Business | $100/mo min | Unlimited | 1 hour | 4 hours | No (shared pool) |
| Enterprise On-Ramp | $5,500/mo min | Unlimited | 1 hour | 30 minutes | Pool of TAMs |
| Enterprise | $15,000/mo min | Unlimited | 1 hour | 15 minutes | Dedicated TAM |
Technical Account Manager (TAM):

AWS Trusted Advisor access by plan:

6. AWS Organizations & Consolidated Billing
Consolidated Billing benefits:
- Single bill for all AWS accounts in the organization
- Combined usage qualifies for higher volume discount tiers (e.g., S3 storage, data transfer)
- Shared Reserved Instance and Savings Plans savings — unused RI capacity in one account can apply to another
- Free to use — no charge for Organizations itself
Service Control Policies (SCPs):
- Define maximum permissions for accounts in the organization
- Cannot grant permissions — only restrict them
- An SCP deny overrides any IAM allow in the affected accounts
7. AWS Pricing Calculator
- Free web-based tool at calculator.aws — no AWS account required
- Estimate monthly costs for planned architectures before deploying
- Add services, configure expected usage, generate shareable estimate URL
- Replaces the older TCO Calculator and Simple Monthly Calculator
