The second "usage" should be "estimated usage". It just extrapolates from how much you used. It isn't perfect. But you have only actually used $0.01 in "current usage". So really, really low.

This is what it looks like without the words cut off

The UI shouldn't be cutting those words off

Oh I got scared that today only I signed up

And today only I got billed 2 $

Also, with the hobby plan, you get $5 (the cost of the plan) as a "gift". As in, you are charged a minimum of $5 a month. But you are only charged on usage. IE, if you use $7 of resources, you are charged $7 for the month. And if you use $3 of resources for the month, you are charged $5 for that month. Does this make sense?

Yeh it make sense

You mean minimum of 5$ will be charged even if I use less resources

And above that even if I go i will only be charged 5 - the usage

Why 3 it should be 2 or 3?

I was using random numbers in my examples

Got it

Another thing I would like to confirm 5$ worth of space in db is free right?

Monthly?

Yea. The cost of the plan.
It is a very good system. Lets them keep the lights on while also not pushing a high cost onto the user.

$5 of total usage. Be that CPU, Mem, or storage space.

Oh above that how much I will be charged on db side?

Right. Lets say you have usage that looks like:
$1 on CPU
$4 on memory
$2 on disk
$1 on network egress
You would be charged $8 for that month

But if you had usage that looked like:
$0 on CPU
$2 on memory
$1 on disk
$0 on network egress
You would be charged $5 for that month.

DB is "disk" space. Assuming you are using a volume on railway.

As for how much does a postgres db cost a month? Well, exact number is hard to say. But it should be less than this. You can play around with numbers on https://railway.app/pricing

i want to confirm only first month is gift period? which gives 5$ free?

or its every month?

You receive that gift every month?

Yes

Thats amazing

Ngl railway is great for low usage services
