Key takeaways
- A conclusion restates your answer in new words, synthesises the main points and explains their significance.
- Do not introduce new evidence or arguments; you may point to implications and future questions.
- Research paper conclusions also note limitations and recommendations; report conclusions are often paired with recommendations.
- Start with a sentence that signals synthesis, such as 'Taken together' or 'This analysis shows', rather than relying on 'In conclusion'.
- Length is usually 5–10% of the whole text: one paragraph in an essay, a short section in a paper.
What a conclusion needs to do
To write a conclusion, restate your thesis or main finding in fresh words, connect your key points to show what they add up to, and end by explaining why the result matters or what should happen next. A conclusion is not a summary of every paragraph; it is the final step of the argument.
Think of it as answering the reader's last question: So what? The introduction told them what you would show. The body showed it. The conclusion tells them what it means now that they have seen the evidence.
A three-part method for any conclusion
- Return to the answer. Restate the thesis statement or main finding, rephrased in light of what you have shown. It should sound more confident and more precise than in the introduction, because you have now earned it.
- Synthesise, do not list. Show how your main points fit together. Instead of First I discussed X, then Y, explain how X and Y together support the answer.
- Close with significance. End with one of these: a practical implication, a connection to a wider debate, a recommendation, or an open question that your work raises.
In a 1,500-word essay, this is usually one paragraph of five to seven sentences. In a research paper or dissertation it may be a short section of several paragraphs, with the same logic stretched out.
How to start a conclusion paragraph
In conclusion is not wrong, but it is overused and tells the reader nothing about your argument. A stronger opening sentence signals that you are pulling ideas together. Some options:
| Purpose | Ways to start a conclusion |
|---|---|
| Synthesis | Taken together, these findings suggest... / Across all three cases... |
| Restating the answer | This essay has argued that... / The evidence reviewed here points to... |
| Returning to the opening | The nurse waiting for her bus at the start of this essay... |
| Research findings | This study set out to examine... The results indicate... |
| Report | On the basis of this review, the committee should... |
Choose one that fits your discipline and tone. In many sciences, a plain This study shows is preferred over a literary flourish.
Essay conclusion example
Here is an original example for an essay arguing that schools should start later in the morning.
Taken together, the evidence on adolescent sleep, attendance and attention points in the same direction: secondary schools that start at 8:45 a.m. or later serve their students better than those that start at 8:00. The biological shift in teenagers' sleep timing is not a matter of discipline, and schools that ignore it ask students to learn at the hour they are least able to. The practical objections, chiefly bus schedules and after-school activities, are real but solvable, as districts that have made the change demonstrate. The more difficult question is why a reform with such consistent support has been adopted so slowly, and whether school timetables are designed around learning or around habit.
The first sentence restates the thesis with the evidence folded in. The middle sentences synthesise the reasons and dispose of the main objection briefly. The last sentence widens the significance without starting a new argument.

How to write the conclusion of a research paper
A research paper conclusion includes the same three moves plus two that are specific to research: limitations and directions for future work. A useful order is:
- Restate the research question and the main answer.
- Summarise the key findings in two to four sentences, without repeating statistics in detail.
- Explain the contribution: what is now known, or known more securely, because of this work.
- Acknowledge the main limitations honestly and briefly.
- Suggest specific future research or practical recommendations.
An original example for a study on part-time work and student retention:
This study asked whether part-time employment affects first-year retention among first-generation university students. Students working more than 15 hours a week were noticeably less likely to continue into their second year, and the association was explained largely by reduced participation in peer study groups rather than by lower grades. These results suggest that the problem is less about academic ability than about access to the informal networks that help students stay. Because the data come from a single institution and rely on self-reported hours, the findings should be tested across different settings. Universities could respond by scheduling peer study sessions at times that working students can attend, and future research could evaluate whether such changes improve retention.
For the bigger picture of where this section sits, see our guide on how to write a research paper. In a dissertation, the conclusion chapter follows the same pattern at greater length and links back to each research question in turn.
Conclusions in reports and lab reports
In a business, policy or technical report, the conclusion states what the analysis found in direct terms, often as short paragraphs or numbered points, and is followed or accompanied by recommendations. Readers of reports frequently skip straight to the conclusion, so make it understandable on its own.
In a lab report, the conclusion is usually brief: state whether the results supported the hypothesis, give the key result with its value, mention the main source of error, and suggest one improvement. For example: The results supported the hypothesis that higher salinity reduces germination: germination fell from 92% in the control to 48% at the highest salt concentration. Uneven watering between trays may have added variability; future trials should use automated irrigation.
Revising a weak conclusion: before and after
Seeing a conclusion improve step by step is often more useful than reading rules. Here is a weak draft for an essay arguing that cities should protect street trees during construction.
Before: In conclusion, this essay has talked about street trees. First, I discussed shade. Then I discussed flooding. Finally, I discussed property values. Trees are very important and everyone should care about them. Only time will tell what happens.
The draft lists paragraphs in order, makes a vague claim (very important), adds no significance and ends on a cliche. Here is a revision:
After: Mature street trees do work that cities would otherwise pay for: they cool pavements on hot days, absorb stormwater that would overload drains, and raise the value of the homes around them. Because these benefits take decades to grow and minutes to remove, the cheapest moment to protect a tree is before construction begins. Requiring developers to fence root zones and replace any tree they damage at equivalent size would cost little in comparison. The real question for planners is not whether trees are worth keeping, but why a city would treat decades of free infrastructure as an obstacle.
The revision combines the three reasons into one sentence, draws out the logic connecting them, makes a specific recommendation and ends with a sharper question.
A quick self-check
- Could a reader who skipped to the conclusion tell what you argued?
- Does it sound more certain, and more precise, than your introduction?
- Is there any sentence you could delete without losing meaning?
- Does the final sentence leave the reader with something specific to think about?
In argumentative essays, the conclusion can also briefly acknowledge the strongest counterargument you answered, showing that your position has survived a fair test. Our guide to the argumentative essay shows how that fits into the overall structure.
Mistakes to avoid
- Introducing new evidence. If a point is important enough to need evidence, it belongs in the body.
- Copying the introduction. Readers notice repeated sentences. Rephrase in light of what has been shown.
- Listing every point mechanically. Synthesise instead of retelling the essay paragraph by paragraph.
- Overclaiming. A study of one school does not prove something about all schools. Match the strength of your conclusion to the strength of your evidence.
- Apologising. Phrases like this is just my opinion undercut your argument. Note genuine limitations plainly instead.
- Ending on a cliche. Avoid closing lines such as only time will tell. End on a specific implication.
Getting feedback on your conclusion
Conclusions are often written last and in a hurry, which is why they are a common place to lose marks. A second reader can tell you quickly whether yours answers the question and adds significance. Our essay feedback service comments on drafts you have written, and for longer papers our research paper coaching covers how the conclusion fits the whole argument. The writing stays yours throughout.
