DynamoDB's cost model is built on Read and Write Capacity Units. It's likely that you'll start out in the free tier and it's still good to start building up an understanding of how what you do in DynamoDB will affect how much you pay.

Don't Worry too much. The amounts we're talking about here are dollars for up to a million units.

  • $1.25 per million write request units
  • $0.25 per million read request units
