AWS DynamoDB cost questions

How is AWS DynamoDB billed?

AWS DynamoDB is billed per metered unit of usage. See the table above for each dimension and its rate, and the official pricing page for plan minimums and included allowances.

Why is my AWS DynamoDB bill higher than expected?

The per-unit rate is only one of the four numbers that set your bill. The others are how much your app uses AWS DynamoDB, how often, and across how many users. Long prompts, retries, multi-step agents, and uncached repeated context all multiply the rate. PrePrice models that usage from your code so the number is real, not a guess.

Where do these AWS DynamoDB prices come from?

From AWS DynamoDB's official pricing page (aws.amazon.com), verified June 14, 2026 and re-checked on a schedule. Pricing changes often, so confirm the live rate before you commit.
