The price of an S3 bucket in the United States depends on storage used, access patterns, and data transfer. This guide outlines typical cost ranges in USD and highlights common drivers and savings options.
Notes on pricing: Storage costs are the largest component, while requests, data transfer, and management features add smaller, regular charges.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Storage (per GB, S3 Standard) | $0.018 | $0.023 | $0.031 | First 50 TB per month; tiered by total storage |
| Storage (per GB, S3 Standard-IA) | $0.012 | $0.018 | $0.025 | Longer-term infrequent access; lower latency |
| PUT/LIST/DELETE requests (per 1,000) | $0.005 | $0.005 | $0.006 | Includes uploads and bucket operations |
| GET/SELECT requests (per 1,000) | $0.0004 | $0.0004 | $0.0006 | Data retrieval requests |
| Data transfer out to Internet (per GB) | $0.09 | $0.085 | $0.12 | First 10 TB per month; varies by region |
| Data transfer in (per GB) | $0.00 | $0.00 | $0.00 | Typically free into S3 |
Overview Of Costs
Cost range expectations: a small, low-traffic bucket may cost under $1 per month, while a busy, multi-region dataset can reach many hundreds or thousands of dollars monthly. Assumptions: moderate storage of 500 GB, mixed requests, and standard data egress to the Internet.
Cost Breakdown
| Category | Low | Average | High | Assumptions |
|---|---|---|---|---|
| Materials | $9 | $11.50 | $15 | Stored data; includes 500 GB at $0.023/GB |
| Labor | $0 | $0 | $0 | Setup and ongoing maintenance mostly automated |
| Requests | $5 | $15 | $40 | Moderate PUT/LIST and GET activity |
| Data transfer out | $9 | $15 | $60 | Assumes 150 GB/mo to Internet |
| Taxes & fees | $0 | $0 | $10 | Depends on location and usage |
| Contingency | $0 | $0 | $5 | Buffer for spikes in traffic |
| Total per month | $23 | $36.50 | $130 | Storage, requests, egress, and minor extras |
Assumptions: region, specs, labor hours.
What Drives Price
class=”cost-driver”>Storage class choice significantly shifts cost. S3 Standard costs more per GB than S3 Standard-IA or Glacier storage classes, but provides lower latency and immediate access. class=”cost-driver”>Data egress to the Internet is a major variable, with higher monthly transfer driving higher bills. Request patterns (PUT/GET/LIST) impact monthly totals, especially in apps with heavy write or read activity.
Regional Price Differences
Prices for S3 vary by region. In general, the same storage class can cost up to 8–15% more in some urban areas or multi-region configurations compared to midwestern or southern regions. Regional pricing deltas reflect data transfer bandwidth and local AWS pricing tiers.
Ways To Save
Choose a storage class aligned with access needs to lower ongoing storage costs, such as Standard-IA for infrequently accessed data. Implement lifecycle rules to move older data to cheaper classes automatically. Consider data transfer patterns and compress data to reduce ingress/egress where possible. Monitor and set alerts for unusual request spikes to avoid unexpected charges.
Real-World Pricing Examples
Basic scenario — 200 GB stored, 1,000 PUT requests/mo, 5,000 GET requests/mo, 20 GB egress. Approximate monthly total: $5–$12 depending on class and region.
Mid-Range scenario — 1,000 GB stored in Standard, 50,000 PUT/LIST, 200,000 GET, 150 GB egress. Approximate monthly total: $25–$120 depending on region and whether IA or Glacier is used for older data.
Premium scenario — 5,000 GB stored across two regions, frequent PUT/LIST, heavy GET, 1 TB egress. Approximate monthly total: $300–$900 with higher transfer and cross-region replication costs.
Assumptions: region, specs, labor hours.
Notes: The exact pricing depends on storage class, S3 features (such as Replication, Inventory, or Object Lock), and any data-transfer discounts or commitments. Users should model monthly costs based on expected storage, average object size, and traffic patterns.
