Can you share a screenshot of the cost breakdown?

where do i find this?

how on earth is the memory $55

Take a look at https://railway.com/workspace/usage and see what service uses the most RAM

this?

Go back one month on the top and below there's a breakdown by project and then inside it by service

ah i see now. ok, and if the service is offline it doesn't use any ram correct?

Yep
