It's no advantage to retire (8)

I believe the answer is:

drawback

I'm a little stuck... Click here to teach me more about this clue!

'it's no' is the definition.
I can't tell whether this defines the answer.

'advantage to retire' is the wordplay.
'advantage' becomes 'draw' (I can't justify this - if you can you should believe this answer much more).
'to retire' becomes 'back'.
'draw'+'back'='DRAWBACK'

Can you help me to learn more?

(Other definitions for drawback that I've seen before include "Fly in the ointment" , "Hindrance - disadvantage" , "Hindrance - retreat" , "Catch" , "Disadvantage, problem" .)

I've seen this clue in The Guardian and The Globe and Mail.
