Frequently Asked Questions

How accurate is this DynamoDB pricing calculator?

This DynamoDB pricing calculator uses official AWS pricing data updated regularly from Amazon's public pricing API. It accounts for regional pricing differences, capacity modes, and free tier benefits. For production budgets, verify final costs in the AWS Billing console since pricing can change.

Should I use on-demand or provisioned capacity for DynamoDB?

Use on-demand for unpredictable workloads, new applications, or when automatic scaling is preferred. Use provisioned capacityfor steady, predictable traffic - it's typically 60-70% cheaper than on-demand for consistent workloads. This calculator compares both modes for your usage pattern.

What are the main DynamoDB cost components?

DynamoDB pricing includes: Capacity charges (WRU/RRU for on-demand or WCU/RCU-hours for provisioned), Storage ($0.25/GB-month standard, $0.10/GB-month for Standard-IA), and optional features like Global Tables, Point-in-Time Recovery ($0.20/GB-month), and DynamoDB Streams.

What's included in the DynamoDB Free Tier?

The DynamoDB Free Tier (always free, not just 12 months) includes 25 GB of storage, 25 WCU and 25 RCU for provisioned capacity, or 200 million requests/month for on-demand mode, plus 2.5 million DynamoDB Streams read requests.

When should I use DynamoDB Standard-IA table class?

Use Standard-IA (Infrequent Access) for tables where storage is the dominant cost and access is infrequent. Standard-IA offers 60% lower storage cost ($0.10/GB vs $0.25/GB) but higher request costs. Ideal for log tables, historical data, or archive workloads exceeding 100 GB.

How much do DynamoDB Global Tables cost?

Global Tables replicate writes across regions. You pay the standard read/write costs in each region plus replicated write charges ($0.625/million replicated write request units for on-demand). Use this calculator to estimate multi-region costs by enabling Global Tables and specifying the number of regions.

How does DynamoDB compare to RDS or Aurora pricing?

DynamoDB is a serverless NoSQL database with pay-per-request pricing, while RDS and Aurora are relational databases with instance-based pricing. For high-throughput, key-value workloads, DynamoDB is often more cost-effective. Compare using our RDS pricing calculator and Aurora pricing calculator.
