Which billing dimensions apply?
us-east-1list rates, pricing as of 2026-06-25. AWS-service events on the default bus are excluded. Cross-region replication and data transfer not modeled. Source: AWS public pricing.
Select every line item you use. AWS-native service events on the default bus cost $0.
Who This Tool Is For
Platform engineers and FinOps leads building event-driven workflows with custom event buses, Pipes, or scheduled invocations.
Why We Built This Tool
EventBridge looks like a $1/million-events service until Pipes, Schema Discovery, Archive retention, and cross-region replication stack on the same bus.
What Problem It Solves
- Dimension stacking. Six independent billing lines — model only what you actually use.
- Custom vs AWS events. AWS-service events on the default bus are free; custom publishes drive the bill.
- Operational leaks. Schema Discovery left on in production and idle Archive retention are common surprises.

Frequently Asked Questions
Where do these EventBridge prices come from?
AWS published us-east-1 list prices (AWS EventBridge pricing), pricing as of 2026-06-25.
Are AWS-service events on the default bus free?
Yes. Events from AWS services (S3, EC2, CodePipeline, etc.) on the default event bus incur no publish or rule-evaluation charge. Custom application events are billed at $1.00 per million.
How is EventBridge Pipes priced?
Pipes bills $0.40 per million events processed, independent of source (SQS, Kinesis, DynamoDB Streams) or target (Lambda, Step Functions, event bus). Source and target services bill separately.
What does Schema Discovery cost?
Schema Discovery inspects events passing through a bus and generates schemas at $0.10 per million events evaluated. Enable on dev/staging buses; disable in production once schemas are stable.
How does Archive storage work?
Archive stores events at $0.10 per GB-month. Replay is free as an action, but replayed events re-incur standard publish rates. Set retention to avoid indefinite storage charges.
EventBridge vs SNS — when is EventBridge worth the premium?
EventBridge adds content-based routing, schema discovery, archive/replay, and cross-account sharing. For simple fan-out to known subscribers, SNS-to-SQS is often cheaper — compare with the SNS and SQS calculators.
