Grant makes a profit (5)
I believe the answer is:
yield
I believe this is a double definition.
'grant' is the first definition.
(synonyms)
'a profit' is the second definition.
(I've seen this before)
'makes' is the link.
(Other definitions for yield that I've seen before include "Investment interest" , "Render" , "Produce as harvest or surrender" , "bow" , "Bring forth" .)
