Starting price anticipating terminal pay-out (5)
I believe the answer is:
spend
'pay-out' is the definition.
'starting price anticipating terminal' is the wordplay.
'starting price' becomes 'sp'.
'anticipating' is a charade indicator (letters next to each other).
'terminal' becomes 'end' (I've seen this in other clues).
'sp'+'end'='SPEND'
(Other definitions for spend that I've seen before include "Use up (one's resources)" , "Outlay" , "amount" , "Run through" , "Pass (time) in a specified way" .)
