Will deleted EC2 instances be counted in the free tier

Question

I am planning to create a lot of EC2 instances in the AWS free tier account. I am not yet familiar with the pricing details. Suppose we can create a maximum of 20 instances under free tier. Let's say  I have created some 18 instances. Again if I want to create a 5 more, it's not possible as it reaches max, so I am planning to delete 3 and create another 5. Now, will those deleted instances be taken to consideration or not?

Answer 1

Based on what you said, I am assuming that you have not gone through pricing details yet. With AWS free tier, you can run a maximum of 750 free machine hours of micro instances. You will just be billed for usage of micro instances that exceeds 750 hours per month, which would be equivalent to one micro instance running 24x7. You'd also be billed normally for any of the larger instance configurations.
