Quick Fix: For 10% or higher, use 25%. For 1–9, write five percent. Start a sentence with Fifteen percent. In tables, use 10%; avoid symbols without numerals.
If you’re formatting percentages in APA 7th edition (current as of 2026), place the percent symbol (%) immediately after the numeral in running text, tables, and figures. Always spell out “percent” when the number is written out or starts a sentence, title, or heading.
What’s happening with APA percentage formatting?
APA 7th edition requires consistent percentage formatting to avoid confusing readers.
APA 7th edition sets clear rules for displaying percentages to maintain consistency and readability in academic writing. Misplacing the percent symbol or mixing numeral and word forms can confuse readers and risk editorial or citation errors. The guidelines distinguish between spelled-out numbers and numerals, and clarify usage in tables, ranges, and headings.
How do I format percentages correctly in APA style?
Use numerals with % for 10 or higher, spell out 1–9 with “percent,” and always start sentences with the word “percent.”
- Use numerals with % for 10 or higher: Attach the symbol directly to the number. Example: 45%, 92%.
- Spell out numbers 1–9 with the word “percent”: Example: three percent.
- Start sentences, titles, or headings with the word “percent,” even with numerals: Example: Sixty percent of respondents.
- In tables and figures: Use the symbol only when a numeral precedes it (e.g., 20%); otherwise, spell it out (e.g., “What percentage of the sample?”).
- For ranges and spans: Use an en dash without spaces: 15%–30%.
I tried following the rules, but my percentages still look wrong. What now?
Double-check for spacing issues and sentence-start formatting, or consult the official APA Style site for edge cases.
Try these adjustments if your percentages still don’t match APA style:
- Remove spacing: Ensure no space exists between the number and the symbol (e.g., 50%, not 50 %). APA requires direct attachment.
- Spell it out at sentence starts: When in doubt, begin sentences with “percent” to avoid ambiguity.
- Check the official APA Style site: For updates or edge cases, consult the APA Style website for the latest guidance.
Any quick tricks to catch percentage formatting mistakes early?
Run a document-wide search for % symbols and validate tables against your raw data.
- Run a document-wide search: Press Ctrl+F, type %, and review each instance to confirm proper formatting.
- Use a custom Word template: Create or import an APA-compliant style that auto-applies correct number and percentage formatting during typing.
- Validate tables against raw data: Cross-check table entries with source spreadsheets to prevent mismatches between text and visual displays.
- Monitor APA updates: Bookmark the APA Style website, as minor formatting shifts can occur even after 2026.
Can I use the percent symbol (%) in tables?
Yes, but only when paired with a numeral—otherwise spell out “percent.”
In tables and figures, use the symbol only when a numeral precedes it (e.g., 20%). For questions or labels without numbers, spell it out (e.g., “What percentage of the sample?”). Honestly, this is the best way to keep tables clean and consistent.
What if I need to write a percentage at the start of a sentence?
Always spell out the word “percent” when starting a sentence.
Even if the number is 10 or higher, begin with the word “percent.” Example: Fifteen percent of participants preferred option A. That’s the rule—no exceptions.
How should I handle percentage ranges in APA?
Use an en dash without spaces between the numbers and symbol: 15%–30%
For ranges, connect the numbers directly with an en dash. No spaces, no extra symbols. Just 15%–30%—simple as that.
Is there a difference between “percent” and “%” in headings?
Yes—spell out “percent” in headings, just like in sentences.
Headings follow the same rules as regular text. If you’re starting a heading with a number, write it out: Fifteen percent of the population. No symbols allowed at the beginning.
What about percentages in figure captions?
Use numerals with % in captions, but follow the same rules as tables.
In figure captions, attach the symbol to numerals (e.g., 45%). If the caption starts with a number, spell it out (e.g., Fifty percent of cases). Consistency matters here.
Can I mix spelled-out and numeral percentages in the same paragraph?
Generally not—stick to one style per paragraph for clarity.
Mixing formats (e.g., three percent in one sentence and 5% in the next) can look sloppy. Pick a style and stick with it unless you’re starting a new sentence.
What’s the most common mistake people make with APA percentages?
Adding a space between the number and symbol, like 50 % instead of 50%.
That tiny space breaks APA rules. The symbol must hug the number: 50%, not 50 %. It’s an easy fix, but one that trips up a lot of writers.
Do these rules apply to percentages in footnotes?
Yes—footnotes follow the same formatting as the main text.
Whether it’s a footnote or a sentence, the rules stay the same. Use numerals with % for 10+, spell out 1–9, and avoid symbols at the start of phrases.
Where can I find the official APA guidelines for percentages?
The APA Style website is the definitive source for percentage formatting rules.
For the most up-to-date rules, consult the APA Style website. They update guidelines occasionally, so bookmark it and check back now and then.
Can I use “per cent” instead of “percent” in APA?
No—APA always uses “percent,” never “per cent.”
“Per cent” is the British spelling, but APA sticks with “percent.” It’s not negotiable, so update your settings accordingly.
