Amazon DynamoDB is a fully managed, serverless NoSQL database with consumption-based pricing — there are no fixed seat-based plans, and enterprise pricing requires contacting AWS Sales, though standard pay-per-use rates are published publicly. At small scale, DynamoDB is extremely cost-effective: a permanent free tier covers 25 GB of storage and approximately 200 million requests per month with no expiration, and typical low-traffic applications pay under $5/month. As throughput grows, on-demand pricing runs $1.25 per million write request units and $0.25 per million read request units, while switching to provisioned capacity with 1-year reserved commitments reduces costs by approximately 56% for steady workloads.

Amazon DynamoDB Year 1 Total Cost by Company Size
Real deployment costs including licenses, implementation, training, and admin — not just the sticker price.
A DynamoDB table with approximately 1,000 small items and minimal traffic, as reported by an engineering team using it for a low-scale internal use case.
On-demand pricing for approximately 1 million write request units and 1 million read request units per month. Excludes storage costs within the permanent free 25 GB tier.
On-demand pricing for 3.55 million write request units and 3.55 million read request units per month. Represents a small production workload with real traffic.
Full serverless application serving a side business with thousands of users, combining Lambda, S3, and DynamoDB. Cost covers the entire stack — not DynamoDB in isolation.
One-time cost of bulk-writing 2 billion rows to two DynamoDB tables via batch write API calls, without using the S3 import method. Illustrates the penalty for misunderstanding per-item billing vs. per-call billing.

Detailed pricing comparisons:
Amazon DynamoDB Contract Terms
Amazon DynamoDB contracts do not auto-renew. Changes require No contract — usage-based billing, can stop usage at any time. These terms are sourced from verified buyer experiences.
Can switch from on-demand to provisioned and reduce capacity; however, provisioned capacity reductions are limited to once per day
How to Negotiate Amazon DynamoDB Pricing
Amazon DynamoDB contracts are negotiable. These 6 tactics are sourced from real buyer experiences and procurement specialists.
Commit to a 1-year reserved capacity purchase for tables with predictable, sustained throughput. Reserved capacity saves approximately 56% compared to standard provisioned pricing. Best applied after validating actual usage patterns over several months to avoid over-committing to capacity you won't use.
HN (jakozaur, 2018)Use on-demand pricing initially to avoid provisioning guesswork. Once DynamoDB spend exceeds $50–$100/month, it becomes worth switching to provisioned capacity with auto-scaling. The on-demand to provisioned breakeven is at roughly 14% sustained utilization — below that, on-demand is cheaper; above it, provisioned wins.
HN (abd12, 2020)For initial data migrations or large backfills, use DynamoDB's table creation from S3 import instead of batch write API calls. S3 import pricing is far cheaper than paying per-row write request units. This avoids the documented mistake of spending $5,000–$8,000 on bulk loads that could have cost a fraction of that via S3 import.
HN (efxhoy, 2023)The highest-impact cost optimization is designing partition and sort keys so all access patterns are served by targeted queries rather than scans. A scan reads every item in the table; a targeted query reads only matching items. Investing in proper NoSQL data modeling upfront can reduce read costs by orders of magnitude at production scale.
Reddit/HN community consensusDynamoDB charges per KB read and written. Storing only lookup keys and small metadata fields in DynamoDB — with actual large payloads (files, documents, rich text) in S3 — keeps item sizes under 1 KB, minimizing both write/read unit consumption and storage costs significantly.
Reddit (AcrobaticLime6103, 2024)Large AWS accounts ($1M+/year AWS spend) can negotiate significant discounts on DynamoDB and related services. AWS enterprise teams have offered substantial discounts to retain large accounts evaluating migration to alternatives. Credibly building a migration plan to Cassandra or CosmosDB is the primary negotiating leverage. AWS has been documented discounting services by 40–80% for large accounts.
Reddit (anengineerandacat, 2024)Amazon DynamoDB Pricing FAQ
01 Does Amazon DynamoDB have a free tier?
Yes — and it is permanent. DynamoDB's free tier does not expire after 12 months. It includes 25 GB of storage, 25 provisioned Write Capacity Units (WCU), and 25 provisioned Read Capacity Units (RCU) per month, which AWS states is sufficient for approximately 200 million requests per month.
02 How much does a DynamoDB batch write of 25 items cost?
25 write request units — one per item, not one per API call. DynamoDB bills per row written regardless of batch size. A BatchWriteItem call with 25 items costs the same as 25 individual PutItem calls. This is one of the most common and costly misunderstandings, with developers reporting $5,000–$8,000 charges from single bulk load operations.
03 When should I use on-demand pricing vs. provisioned capacity?
On-demand is best for unpredictable or spiky traffic — you pay per request with no capacity planning required. Provisioned is best for steady, predictable workloads where you can reserve capacity in advance. For identical throughput, provisioned is approximately 7x cheaper than on-demand at full utilization — the breakeven point is roughly 14% sustained utilization. Auto-scaling allows provisioned tables to adapt to changing demand automatically.
04 How much can I save with DynamoDB reserved capacity?
Approximately 56% compared to standard provisioned pricing, with a 1-year commitment. Reserved capacity is purchased for specific read and write unit quantities and applied against provisioned tables. It does not apply to on-demand pricing mode.
05 Why are DynamoDB scans expensive?
A scan reads every item in the table sequentially, consuming read request units for each item regardless of how many match your filter. Unlike a targeted query using a partition key — which reads only relevant items — a scan on a table with millions of records consumes millions of read units. The solution is to design your data model so all access patterns are served by partition key queries or GSI queries, not scans.
06 Does DynamoDB become more expensive as my application scales?
Yes — it scales linearly with throughput. At small scale the service is very affordable (often under $5/month), but at sustained production volumes multiple engineering teams have reported switching to self-managed Cassandra or other databases when DynamoDB costs exceeded the fully-loaded cost of self-hosted infrastructure. However, most small-to-medium applications report spending under $50/month.
