AnswerEdit

This array formula will do it

=SUM(VALUE(RIGHT(A1:A2000,LEN(A1:A2000)-SEARCH("-",A1:A2000))))

ensure that the range is the same as the range you are actually using, and that all cells have a - sign in them or it will fall over - enter the formula above and use ctrl shift enter to accept it - this will then return the result you want.
