How to Write a Conclusion for an Essay
Overview
A strong essay conclusion does three things: restates the thesis in fresh language, synthesizes (not just summarizes) the main points, and ends with broader significance so the reader understands why the argument matters beyond the essay itself.
Step 1: Restate Your Thesis in New Words
Your conclusion opens by echoing the thesis, but it should sound different from the introduction. The reader has now read the entire essay, so your restated thesis should reflect the weight of the evidence.
Introduction thesis: "Public universities should eliminate legacy admissions because the practice perpetuates socioeconomic inequality and undermines merit-based selection."
Restated in conclusion: "Legacy admissions policies at public universities actively entrench privilege at the expense of qualified applicants, making them incompatible with any institution that claims to value merit."
Notice the restated version is more confident. After presenting the evidence, you can afford to be more direct.
Step 2: Synthesize Your Main Points
Do not list your points one by one ("First, I discussed X. Then, I discussed Y."). Instead, show how they connect.
Weak (summary): "This essay discussed the economic costs, the ethical problems, and the legal challenges of legacy admissions."
Strong (synthesis): "The economic data, ethical arguments, and recent legal challenges all point to the same conclusion: legacy admissions cannot survive scrutiny from any angle."
Synthesis pulls the threads together. It answers the question: "What do all of these points, taken together, prove?"
Step 3: End with Broader Significance
The final sentence is the last impression you leave. Four effective closing strategies:
Call to action: "State legislatures should pass legislation banning legacy preferences at all publicly funded universities within five years."
Prediction: "If public universities do not act voluntarily, the courts will eventually force the change."
Broader connection: "The legacy admissions debate is, at its core, a test of whether American higher education values its ideals or its endowments."
Open question: "The remaining question is not whether legacy admissions will end, but how much damage they will do before they do."
Avoid cliches like "Only time will tell" or "In today's society." Be specific.
Conclusion Examples by Essay Type
Argumentative essay: "Legacy admissions policies actively entrench privilege at the expense of qualified applicants. The economic costs to overlooked students, the ethical contradiction with meritocratic ideals, and recent legal precedents all point to the same conclusion: public universities must end the practice. The question is not if, but when." Informative essay: "The water cycle drives weather patterns, shapes ecosystems, and sustains agriculture. Understanding evaporation, condensation, and precipitation as interconnected processes, rather than isolated events, reveals how a disruption at any stage ripples through the entire system." Narrative essay: "That summer taught me that confidence is not the absence of fear. It is the decision that the thing you want matters more than the thing you are afraid of. I still get nervous before every performance, but I no longer let that stop me from walking onstage."
Common Mistakes to Avoid
Introducing new arguments: If you have a new point, it belongs in a body paragraph. The conclusion closes the loop; it does not open a new one.
Starting with "In conclusion": This is filler. The position on the page already tells the reader it is the conclusion.
Apologizing or undermining your argument: "This is just my opinion" or "There is not enough research to be sure" weakens everything you wrote. Stand behind your thesis.
Copying the introduction word-for-word: A restated thesis should reflect growth. If the conclusion sounds identical to the introduction, the essay feels like it went nowhere.
Frequently Asked Questions
A conclusion is typically 5-10% of the total essay length, similar to the introduction. For a 1000-word essay, aim for 50-100 words. It should feel proportional to the essay, not rushed or overly drawn out.
No. The conclusion synthesizes arguments you have already made. Introducing new evidence, statistics, or quotes belongs in the body paragraphs. New information in the conclusion suggests your essay structure needs revision.
Avoid it. Phrases like "in conclusion," "to sum up," and "in summary" are filler. Your reader knows it is the conclusion because it is the last paragraph. Start with the restated thesis instead.
Summarizing lists what you said. Synthesizing shows how your points connect and build on each other. A strong conclusion synthesizes: "The economic, environmental, and social costs of fast fashion converge to make regulation inevitable."
