Will I get charged that amount that is shown here?

Hey, please refer to the pricing documentation for a detailed explanation and examples. The hobby plan includes $5 of usage.

So I can use 5$ worth of resources without getting charged additionally?

But what about this, will I get charged this?

This is correct, as the hobby plan includes $5 of usage per month.

So I only got 2.94$ usage for the rest of the month or what?

I just paid for the plan and it seems like I only got $2.96 left

I see this

It is supposed to be $5 for the hobby plan, but since you have $2.96 in credits, it will be $5 - $2.96 = $2.04.

So do I get charged in the next month more?

Do I get charged the $2.04

You will get charged $2.04 the next time. Afterwards, it will be $5 a month, given that you don't have any credits anymore.

Ah so I get charged less the next month?

Yes, because you have $2.96 in credits, which will be used first.

Whys that?

The credits are most likely from your trial, you get $5 once you sign up.
