Requests, not messages — and why batching cuts the bill 10×.
Queues bill requests, not messages, so batching up to 10 per call and long polling slash the count. For streaming-scale throughput instead, see the managed Kafka cost calculator.
Free message queue cost calculator — message volume and API requests per message to your monthly SQS-style bill.
Per API request, not per message. Each message typically involves multiple requests (send, receive, delete), so the request count is a few times the message count. The first million requests each month are free; after that it is about $0.40 per million.
Batch. SQS lets you send, receive and delete up to 10 messages per API call, which cuts your billable request count by up to 10×. Also use long polling to avoid empty-receive requests that you still pay for.
