APA 6th Edition

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.

APA 7th Edition

If you're deciding whether to use "percent" or "%", please "use the percent symbol and currency symbols only when they are accompanied by a numeral; also use them in table headings and in figure labels and legends to conserve space" (American Psychological Association, 2020, p. 187). Use "percentage" when a numeral isn't provided e.g., 3% versus "a low percentage".
