Data transfer between instances in the same AZ is free. If the data crosses AZs, you're changed $0.01 per GB in both directions. This is for instances on a VPC. I think the pricing model is different for classic EC2.
There are some exceptions like all traffic between EC2 and ALBs being free.
Edit: Pricing is described at https://aws.amazon.com/ec2/pricing/on-demand/#Data_Transfer https://aws.amazon.com/ec2/pricing/on-demand/#Data_Transfer
