Access to the hobby plan costs 5 dollars a month ( and includes 5 dollars of free usage ). You then continue to pay for the resources you use on the platform, so if you're on hobby plan and you have a server running on Railway that uses 26 dollars of usage a month, then you'll be charged 21 dollars for the server ( since the first 5 dollars of usage a month is free ) and then 5 dollars for hobby plan, totaling 26 dollars a month.
