A conclusion is the last thing your reader sees, so it shapes how the whole essay is remembered. Many students treat it as an afterthought and simply repeat the introduction. A strong conclusion does more: it confirms your argument, shows why it matters and leaves the reader with something to think about. Here is how to write one.
What a Good Conclusion Should Do
- Return to your thesis in fresh wording
- Pull your main points together, without listing them again
- Explain why the argument matters
- Close with a clear final thought
A Five-Step Process
1. Signal that you are wrapping up
You do not need “In conclusion.” A confident change in tone is usually enough, and a more natural opening works better, such as “Taken together, these examples show…”
2. Restate your thesis, but not word for word
If your thesis was “Schools should start later because teenagers need more sleep,” your conclusion might say: “Giving teenagers more time to sleep is not a luxury, but a practical way to improve learning.”
3. Synthesise your main points
Do not repeat each paragraph. Instead, explain how the points connect. What do they show when seen together?
4. Answer “so what?”
Tell the reader why the argument matters. This might be a consequence, a recommendation or a wider implication.
5. End with impact
Finish with a sentence that lingers: a call to action, a link back to your opening example, or a forward-looking idea.
Conclusion Examples
Argumentative: “Universities cannot ignore how quickly AI tools have changed student work. Supervised assessment is not a return to the past, but a way of making sure grades still reflect what students know.”
Analytical: “Fitzgerald’s green light ends up showing more than Gatsby’s longing. It shows how the promise of the future can shape, and ultimately trap, an entire generation.”
These work because they connect back to the argument and say something new, rather than just repeating it. For a real-world example of an issue where this approach works, see our news coverage on UK universities bringing back in-person exams.
Mistakes to Avoid
- Introducing new evidence. If it matters, it belongs in a body paragraph.
- Apologising or hedging. Phrases like “this is just my opinion” weaken your argument.
- Copying the introduction. Readers notice when the last paragraph is the first one reworded.
- Making sweeping claims. “Throughout history, humans have always…” rarely helps.
- Ending abruptly. A conclusion of one sentence feels unfinished.
How Long Should a Conclusion Be?
A common rule is about 5 to 10 percent of the total word count. In a 1,000-word essay, that means roughly 50 to 100 words, or one solid paragraph. Longer academic papers may need a fuller conclusion with limitations and suggestions for further research. Our guide on writing a research paper covers that structure.
Conclusion Checklist
- Does it return to the thesis?
- Does it connect the main points rather than repeat them?
- Does it say why the argument matters?
- Is the last sentence memorable?
- Is there any new evidence that should be moved?
