Expenditures, outlays (5)
I believe the answer is:
costs
I believe this is a double definition.
'expenditures' is the first definition.
(cost is a kind of expenditure)
'outlays' is the second definition.
(cost is a kind of outlay)
(Other definitions for costs that I've seen before include "Charges" , "Damages" , "prices" , "is expensive" , "Is priced at" .)
