Amazon EC2 and S3 Price Calculation

Question

I am new to AWS so in case I made mistake in understanding concepts please explain.

I have a webapp written in Nodejs and I want to deploy it to aws Elastic Beanstalk which requires an EC2 t2.small (linux) instance and aws S3 to store server files.

Strategy:
Data Transfer Out to Internet : Using EC2 to render files from s3
Data Tranfer In from Internet: Using S3 HTTPs commands from aws NodeJS SDK

Question : Do I have to pay additional for migrating files from S3 to EC2 before rendering it ?

Answer 1

Here is very detailed d ata transfer pricing rules list for EC2 instances.

Data transfer IN to EC2 FROM internet is 0.00/GB, which in other words FREE.

Data transfer OUT has costs associated (and in some cases FREE) depending on your setup.

EDIT:

After question edit, still this answer applies. S3 to EC2, no charge. EC2 to outside world has some costs associated.
