Secrets created by EventBridge Connection resources that are used with API Destinations are free when called by EventBridge to authorize requests to the API!
To get a good estimate for using AWS Secrets Manager, use the AWS Pricing Calculator: https://calculator.aws/#/createCalculator/SecretsManager you can configure your number of Secrets, duration and number of API calls.
When I configured it for US-East with 1 Secret for 30 days and 10,000 API events, it returned a monthly price of $0.45 USD.
