Topic type
us-east-1 list rates, pricing as of 2026-06-17. SMS rates use US planning average; actual carrier rates vary. Source: AWS public pricing .
Who This Tool Is For
Backend engineers, platform teams, and FinOps leads designing pub/sub, event notification, or fan-out patterns with SNS.
Why We Built This Tool
SNS bills stack publish request units, per-subscriber delivery attempts, and channel-specific rates — fan-out to many HTTP endpoints can dominate the invoice.
What Problem It Solves
- Topic type choice. Compare Standard free tier vs FIFO ordering costs.
- Payload impact. Large messages multiply billable publish units via 64 KB chunks.
- Delivery mix. Model HTTP/S, email, SMS, and mobile push on one screen.

Frequently Asked Questions
Where do these SNS prices come from?
Rates are AWS published us-east-1 list prices (AWS SNS pricing), pricing as of 2026-06-17.
How are payloads billed?
Each 64 KB chunk of payload counts as one request unit for publish pricing — identical to the SQS request-unit model.
Does Standard SNS have a free tier?
Yes — the first 1 million Amazon SNS API requests per month are free for Standard topics. FIFO topics have no free tier.
How does fan-out affect cost?
Each subscription receives a delivery attempt per publish. HTTP/S delivery is billed separately from publish requests — high subscriber counts multiply delivery charges.
Are SMS rates exact?
No. SMS pricing varies by country, carrier, and message type. This calculator uses a US planning average ($0.00645/message) — verify in the AWS SNS console for production budgets.
SNS vs SQS — when do I need both?
SNS fan-out to multiple SQS queues is a common pattern: SNS handles publish-once, SQS buffers per-consumer processing. Model both sides with this calculator and the SQS pricing calculator.
