Fights fixed cost to cover business degree (7)

I believe the answer is:

combats

'fights' is the definition.
(I know this)

'fixed cost to cover business degree' is the wordplay.
'fixed' indicates an anagram.
'to cover' indicates putting letters inside.
'business degree' becomes 'mba' (Master of Business Administration degree).
'cost' anagrammed gives 'cots'.
'cots' going around 'mba' is 'COMBATS'.

(Another definition for combats that I've seen is " Fights".)

I've seen this clue in The Telegraph.
