If you're deciding whether to use "percent" or "%", please "use the symbol for percent only when it is preceded by a numeral. Use the word percentage when a number is not given" (American Psychological Association, 2010, p. 118). For example, 3% versus "a low percentage".

For more information, please see "The Grammar of Mathematics: Percentage or %?" from the APA Style Blog.
