OSPF cost - LAN segment

Hi all,

May I know a little bit detail about ospf cost,

For example I have topology like below

R1 (fa0/0) |------ SW1------| (e0/0) R3 (s1/0) ======= (s1/0) R2
                      cost ?

------| ethernet segment
=== serial interfaces

Using default bandwidth reference.
I want to ask what will be the cost on the LAN segment between R1 and R3
Is it true that, there will be two different costs there depending on from
which point we look the routing table?
So for example I put loopback on R2 and R1.
The cost from R1 when try to reach loopback on R2 will be lower if I compare
with the cost from R2 when try to reach loopback R1.

Thanks for clarifying
Welly
