The command 'free' shows what you like to know:
$ free
             total       used       free     shared    buffers
cached
Mem:       1551480    1505656      45824          0     101400
1015540
-/+ buffers/cache:     388716    1162764
Swap:       524264      23088     501176

The used/free amounts on the second line are the interesting ones in
this case.
