A conclusion should do in its final paragraph what the whole essay has been building towards: it gathers your separate arguments into one judgement, answers the set question explicitly, and leaves the reader understanding why the answer matters. That takes roughly 5 to 10 per cent of your word count — about 100 to 200 words in a 2,000-word essay — and it requires synthesis, not summary. If your conclusion could be swapped with your introduction without the reader noticing, it is repeating rather than concluding. This guide shows how to make those last words carry weight: how to combine findings instead of listing them, how to land the “so what”, which phrases quietly weaken an ending, and, in a worked pair, exactly how a limp conclusion on a real question differs from a strong one.
Synthesise, do not repeat
The distinction that governs everything else is between summarising and synthesising. A summary works strand by strand: paragraph one said this, paragraph two said that. A synthesis asks what the strands mean together. Perhaps your economic argument pointed one way and your social argument the other — the conclusion is where you weigh them against each other and deliver the overall verdict that neither section could deliver alone. Markers describe this as “drawing the threads together”, and it is often the difference between an essay that describes a debate and an essay that settles one.
A practical way to force synthesis is to ban yourself from mirroring your paragraph order. If the body ran causes, then effects, then objections, do not conclude in that same sequence. Instead, open the conclusion with the judgement your whole analysis supports, then refer back selectively to the two or three pieces of evidence that most decisively support that judgement. One combined sentence — “Taken together, the evidence suggests the reform succeeded on access while failing on equity, and the equity failure is the more significant because it affected precisely the group the reform was designed to help” — does more concluding work than a paragraph that patiently recaps all four sections. Compare that with your essay introduction: the introduction promised a position; the conclusion should now state that position as proven, qualified or revised in light of the evidence. If the evidence changed your mind along the way, say so — a conclusion that honestly refines the opening thesis reads as more scholarly, not less.
Answer the question, then deliver the “so what”
Two moves must both appear. First, answer the question explicitly, using its own terms. If the question asked “to what extent”, your conclusion must contain an extent judgement — “to a considerable extent, but only after 2018” — not a general reflection on the topic. If it asked whether one factor mattered more than another, name the winner and the condition that limits the claim. Markers scanning a conclusion look for this sentence the way examiners look for a final answer in a maths paper; make it easy to find by placing it in the first half of the conclusion, not buried at the end.
Second, earn the “so what”. Significance can take several honest forms: an implication for policy or practice, a challenge to a common assumption, a note on what the answer means for how the topic should be studied, or a carefully bounded pointer to what remains unresolved. What it cannot be is a sudden expansion of scope. An essay on one hospital trust should not conclude with a claim about healthcare everywhere, and an essay on one novel should not end by pronouncing on all literature. Keep the significance at the same scale as your evidence and it will sound authoritative; inflate it and the marker’s trust drops at the very last moment. This relationship between body and ending is part of the wider architecture covered in our guide on how to structure an essay, where the conclusion is planned from the start rather than improvised at the deadline.
What never belongs in a conclusion
The firmest rule is no new evidence. A fresh citation, statistic or case study introduced in the final paragraph cannot be analysed properly, so it weakens rather than strengthens your ending — the marker’s natural response is to wonder why your most telling source arrived too late to be examined. For the same reason, avoid new arguments, new objections and new definitions. If a point feels essential at conclusion stage, that is a signal to revise the body, not to smuggle the point into the last paragraph.
Certain phrases also reliably drain strength. “In conclusion” and “To conclude” as openers are not forbidden, but they are filler: they announce an ending instead of delivering one, and a confident judgement does the job better. Apologetic openers are worse — “This essay has only scratched the surface”, “Due to the word limit, much could not be discussed”, “As a student, it is difficult to say” — because they invite the marker to agree that the work is inadequate at the exact moment you should be most assured. Rhetorical questions, dramatic quotations from nowhere, and the phrase “both sides have good points” without a verdict all create the same impression: a writer backing away from the judgement the essay exists to make. Finally, avoid mechanically echoing your introduction’s wording. Similar content is expected; identical sentences suggest the essay went in a circle.
Worked example: a weak ending and a strong one
Take the question: “To what extent was the printing press responsible for the spread of the Reformation?” A weak conclusion might read: “In conclusion, this essay has discussed the printing press and the Reformation. The printing press was very important and helped Luther’s ideas to spread quickly. However, there were also other factors, such as problems in the Church and support from princes. Overall, both sides have valid points and the printing press was one important factor among many. This topic is very interesting and much more could be said about it.” Notice the faults: it recaps instead of judging, offers no extent beyond “very important”, introduces no synthesis, hedges into “both sides”, and ends with an apology disguised as enthusiasm.
The strong version answers, weighs and signifies: “The printing press was responsible for the Reformation’s speed and reach, but not for its existence. Pamphlet printing turned local protest into a European movement within five years, a pace manuscript culture could not have achieved; yet reform survived only where political protection and existing grievances gave printed ideas an audience prepared to act on them. Print, therefore, deserves to be treated as a necessary accelerant rather than a prime cause — a distinction that matters beyond this case, because it warns against crediting any new medium, in any century, with effects that belong jointly to technology and to the society that receives it.” Same material, similar length — but the second version commits to an extent, combines the strands into a single judgement, and closes with a bounded significance the reader remembers.
Length, drafting order and final checks
Aim for 5 to 10 per cent of the total: roughly 50 to 100 words for a 1,000-word essay, 100 to 200 for 2,000 words, and 200 to 300 for a 3,000-word assignment. A conclusion much shorter than that rarely has room to synthesise; one much longer usually signals repetition or new material creeping in. Most conclusions work as a single paragraph at undergraduate length, though a longer essay may justify two — the judgement first, then the significance.
Draft the conclusion last, but plan it first. Your outline should reserve the conclusion’s verdict in one line from the beginning, so the body is written to earn it. Once drafted, run three checks. Does the first half contain an explicit answer using the question’s wording? Could any sentence be moved into the introduction without change — if so, rewrite it as a judgement rather than a promise? And does the final sentence leave significance rather than apology in the reader’s mind? If a conclusion fails those checks across several assignments, it is usually a planning habit rather than a writing problem, and the structured support described on our assignment help page can help rebuild the habit from outline stage onwards.
Frequently asked questions
Can I start a conclusion with “In conclusion”?
You can, and it will not cost marks by itself, but it adds nothing. Opening directly with your judgement — “The evidence supports the reform only in its revised form” — is stronger and more economical. If you do use a signpost phrase, make sure the sentence that follows contains a verdict, not another summary.
Should the conclusion repeat my thesis word for word?
No. It should restate the position in new language and in its final, evidence-tested form. If your analysis qualified the original thesis — as good analysis often does — the conclusion is where the qualified version appears. Identical wording suggests the argument never developed.
Can I mention a limitation or future research in the conclusion?
Briefly, yes, particularly in longer essays and reports. One sentence acknowledging the main boundary of your evidence, or the question your answer opens up, can add scholarly maturity. Keep it to a sentence, though — a conclusion dominated by limitations reads as apology rather than judgement.
What if I run out of word count before the conclusion?
Never submit an essay with a truncated or missing conclusion — markers treat it as an unfinished argument. Cut from the body instead: trim the longest descriptive passage, shorten the introduction, and protect at least 5 per cent for the ending. Planning word allocations in advance prevents the problem entirely.
Is one paragraph enough for a conclusion?
For most undergraduate essays up to about 3,000 words, yes. A single focused paragraph can answer the question, synthesise the main strands and state the significance. Longer pieces sometimes use two paragraphs, separating the judgement from the implications, but more than that usually means repetition has crept in.
End as you mean the essay to be judged: with a clear answer, honestly weighed, and a final sentence that tells the reader why it mattered. Write the conclusion with the same care as the opening, and the whole piece will feel finished rather than merely stopped.
