Price calculation when deploying web api as lambda function

There is a new template in Visual Studio AWS Serverless Application Template using which I can deploy a WEB API as Lambda function in AWS (https://aws.amazon.com/blogs/developer/running-serverless-asp-net-core-web-apis-with-amazon-lambda/) however I need to know how the pricing is calculated for this model as there is only one lambda which will be deployed in AWS and which will be routing requests to different controllers like accountcointroller or usercontroller. So every request will be considered as one execution for AWS lambda and will be charged accordingly?
