Performance hit on REPLACE function?

Will there be a decline in performance if I add the REPLACE function to my SELECT statement to eliminate quotation marks from the results? For example:

SELECT REPLACE(a.first_name, '"'), REPLACE(a.last_name, '"').............

Would the size of the tables being queried or the size of the result set affect if the REPLACE function hurts performance?
