In most styles, the footnote number goes after the period, with dashes as the main exception.
Footnotes feel tiny until they cost you points. A single raised number in the wrong spot can make an otherwise clean paragraph look sloppy, and it can confuse a reader who’s trying to track what your note applies to.
The good news: most academic styles agree on the core rule. Once you learn that rule, you can handle the tricky cases—quotes, parentheses, dashes, and “this note applies to just these words”—without guessing.
Do You Put Footnote Before Or After Period? The Standard Rule
Put the footnote marker after the period at the end of the sentence. That means the punctuation closes the sentence, then the superscript number sits right after it.
This is the default in Chicago Notes and Bibliography, Turabian, and many other systems that use note numbers. Chicago’s own guidance says the note number follows punctuation marks in almost all cases, with the dash as the standout exception. You can read that rule straight from Chicago Manual of Style guidance on note numbers and punctuation.
Why The Marker Usually Belongs After Punctuation
Think of punctuation as the “closure” of the sentence. The period, comma, or quotation mark finishes the thought. The footnote marker is not part of the grammar. It’s a pointer that says, “There’s a note tied to what you just read.”
Placing the marker after punctuation keeps the sentence readable. Your eye flows through the words, hits the end punctuation, then sees the note number. The page looks calmer too, since the punctuation stays where readers expect it.
There’s also a practical editing angle. Teachers, editors, and academic journals are used to seeing the marker after punctuation. When they don’t, it stands out in a bad way, even if the meaning is still clear.
Placement Rules That Cover Most Papers
End Of Sentence
If the note supports the whole sentence, place the marker at the very end—after the period.
End Of Clause
If the note supports only one clause, you can place it at the end of that clause. The same punctuation logic still applies: write the clause, add its punctuation, then add the marker.
After Quotation Marks
When a sentence ends with a quotation, the closing quotation mark counts as part of the sentence’s finish. Most styles place the footnote marker after the closing quote (and after the period if the period is inside the quote under American punctuation rules). Chicago states the number normally follows a quotation. The safest habit is: close the quote, end the sentence, then place the marker.
After Commas, Colons, And Semicolons
Footnote markers usually follow these marks too. If you place a marker before a comma, it can look like the comma belongs to the note number, not your sentence.
Question Marks And Exclamation Points
Same pattern. Put the marker after the question mark or exclamation point when the note applies to the whole sentence.
Cases Where The Marker May Move
Dashes Are The Standout Exception
When a dash is the punctuation right next to your marker, many style guides put the marker before the dash. The idea is to keep the dash visually tied to the sentence that follows it, not split by a superscript. Chicago calls out the dash as the punctuation the note number precedes.
Notes That Apply To A Single Word Or Phrase
Sometimes you’re not citing the whole sentence. You’re citing one specific claim, term, or number inside it. In that case, place the marker right after the word or phrase it supports. If punctuation follows that word, the marker still goes after the punctuation that belongs to the word or phrase.
Here’s a clean mental test: ask, “What exact chunk of text should trigger the reader to check the note?” Place the marker right after that chunk ends.
Parentheses
Parentheses create a mini-boundary. If your note supports only the parenthetical text, put the marker before the closing parenthesis. If your note supports the whole sentence, put the marker after the period at the end of the sentence, not inside the parentheses.
Some style guides spell out this distinction in their footnote sections. If your instructor or journal provides house rules, follow those first.
Headings And Titles
Many academic guidelines discourage footnote markers in headings. Headings are meant to scan cleanly, and a superscript can look like a typo or an exponent. If a heading needs a citation, it’s often better to cite in the first sentence of the section instead. Purdue OWL’s note guidance also warns against placing callouts in headings in its footnote material. See Purdue OWL guidance on footnote callouts.
How Different Styles Treat Footnote Placement
Most major styles land in the same place: the marker follows punctuation. Differences show up more in footnote formatting than in marker placement, yet it helps to know what your grader expects.
If you’re writing for a class, check the syllabus, rubric, or department handout. A professor’s preference can override a general rule.
| Style Or Context | Marker Vs Period | Notes On Typical Use |
|---|---|---|
| Chicago Notes And Bibliography | After the period | Common in history, humanities, book-style research |
| Turabian Notes | After the period | Student-friendly Chicago variant used in many courses |
| APA Notes | After the period | Footnotes are less common; used for extra detail, not citation |
| MLA Notes | After the period | Notes exist, yet MLA usually prefers Works Cited for sources |
| IEEE Notes | After punctuation | Technical writing often uses bracketed numbers, not footnotes |
| Legal Writing (Many Systems) | After the period | Often heavy note use; check the required rulebook for edge cases |
| Publisher Or Journal House Style | Usually after the period | House rules can differ; follow submission guidelines |
| Class Or Instructor Preference | Depends on the class | If directions conflict, follow the assignment sheet |
Common Mistakes That Lose Marks
Putting The Marker Before The Period By Habit
This is the classic error: you type the superscript, then you type the period. It reads like the period belongs to the note number. Most graders will mark it wrong in note-based styles.
Using The Wrong Spot In Quoted Sentences
Quoted sentences add visual clutter. If the marker lands inside the quotation marks when it should sit outside, it can look like you’re claiming the source included the footnote. Keep the marker tied to your sentence, not inside the quoted text, unless a style guide or publisher requires it.
Stacking Multiple Markers Without A Plan
If a sentence relies on two sources, you can either use one note that cites both sources or use two markers. Many instructors prefer one note with multiple citations, since it’s easier to read.
Restarting Numbering
Most papers number footnotes consecutively from start to finish. Restarting each page can happen if you insert manual superscripts instead of using the word processor’s footnote tool.
Quick Checks For Tricky Sentences
When you’re unsure, run these checks before you submit.
| Situation | Where The Marker Goes | Simple Pattern To Follow |
|---|---|---|
| Note covers the whole sentence | After the final punctuation | Sentence ends.1 |
| Sentence ends with a quote | After the closing quote | “Quoted text.”1 |
| Marker sits next to a dash | Before the dash | Word1—rest of sentence |
| Note applies to a single term | Right after the term ends | Term1 continues… |
| Note applies only to parenthetical text | Before the closing parenthesis | (detail1) |
| Note applies to the full sentence with parentheses | After the sentence period | (detail).1 |
| Two sources support one sentence | One marker, one combined note | Sentence ends.1 (note lists both) |
How To Do It Cleanly In Word And Google Docs
Most footnote placement issues come from typing superscripts manually. Don’t. Use the built-in footnote feature so the numbering stays consistent and your notes stay attached to the right page.
Microsoft Word
- Click where you want the marker to appear in the sentence.
- Go to References → Insert Footnote.
- Word inserts the superscript and moves your cursor to the bottom of the page.
- Type the note text, then click back into the body to keep writing.
If you want the marker after the period, place your cursor after the period first. This one habit fixes most placement errors.
Google Docs
- Click where the marker should go.
- Select Insert → Footnote.
- Docs adds the number and creates the footnote area automatically.
Docs handles renumbering well when you add or delete notes. That’s a lifesaver during revisions.
Formatting The Note Text So It Looks Academic
Marker placement is only half the battle. The note itself needs to look intentional.
Keep Notes Tight
A footnote is not a second paragraph. If you find yourself writing long notes, ask if the content belongs in the main text. Readers shouldn’t be forced to bounce up and down the page to follow your argument.
Match Your Style’s Citation Format
Chicago notes, legal notes, and other systems have their own citation patterns. Use the pattern your course requires. Small details—commas, italics, page ranges—carry weight in formal writing.
Use Consistent Punctuation Inside Notes
Keep note sentences punctuated like normal sentences. If a note is just a citation, end it with a period if your style calls for it. Consistency signals careful editing.
A Simple Editing Routine Before You Submit
Run this routine once at the end. It’s fast, and it catches nearly every footnote placement problem.
- Search your document for superscripts that are not generated by your footnote tool. Replace them with real footnotes.
- Scan each sentence-ending marker. Check that the period comes first, then the marker.
- Scan any dashes near markers. If a marker sits after a dash, change it to before the dash unless your required style says otherwise.
- Check quoted sentences. Make sure the marker sits where your style expects—usually after the closing quote.
- Skim the footnote list. Confirm numbering runs straight from 1 onward with no gaps.
One Last Gut Check
If you remember one rule, make it this: punctuation finishes the sentence; the footnote marker points back to what you finished. That’s why the marker usually sits after the period.
When you hit an edge case, tie the marker to the smallest chunk of text that the note supports. That keeps your citations honest and your page easy to read.
