A long report is written for the people who produced it. A busy reader usually needs a shorter version: what was decided, what the report found, how sure the findings are, and what happens next. An executive summary is that version, and it should fit on one page.

This article is a template and a method for writing one. It is different from a general summary of a PDF. Its job is to support a decision, so it must select, rank, and qualify the findings rather than cover every section. For the general steps, read How to Summarize a PDF with AI first. This article does not describe any tool’s features, and it does not report how any tool performs.

1. Name the decision the summary supports

Write one sentence before you read the report: the decision a reader must make, or the question they must answer. For example: “Should the team renew the vendor contract for next year?” Every item in the summary should either inform that decision or be left out. A summary without a decision tends to become a list of section headings.

2. Read the report’s own summary and conclusions

Start with the report’s executive summary, introduction, and conclusions. Note the authors’ main claims and the page where each one appears. Then read the sections that support those claims. Do not rely on the conclusions alone. Mark any claim that does not have a supporting section in the report.

3. Choose three to five findings

A one-page summary has room for a few findings. Choose the ones that bear on the decision, and rank them by importance to that decision, not by where they appear in the report. For each finding, record:

If a finding has no evidence in the report, leave it out or label it as the authors’ opinion.

4. Use a fixed structure

Use the same five headings every time. A fixed structure lets a reader find what they need quickly, and it makes gaps easy to see.

  1. Decision: the question or choice, in one sentence.
  2. Bottom line: the report’s answer to that question, in two or three sentences, with the main qualification.
  3. Key findings: three to five items, each with its evidence and page reference.
  4. Limits: what the report does not show, and what could change the answer.
  5. Next steps: what the report recommends, and who would act on it, if the report says so.

Keep the whole summary to one page. As a rule of thumb, that is about 350 to 450 words, but check the length in your own layout.

5. Write the bottom line last

Draft the findings first, then write the bottom line from them. The bottom line should not say more than the findings support. If the findings are mixed, say they are mixed. A confident bottom line that the evidence does not support is an easy mistake to make.

6. Check every number and date

Each figure in the summary should appear in the report, with the same unit, period, and base. Check these four things:

  1. Unit and period. A figure for “Q3” is not the same as a figure for “the year.”
  2. Base. A percentage of one department is not a percentage of the company.
  3. Rounding. Use the report’s rounding, not your own.
  4. No new numbers. If you calculate a figure, say so and show the calculation.

Mark each item as confirmed, changed, or not found, the same way you would for any other summary. Remove anything you cannot find in the report.

7. Check the tone

A summary should describe what the report says, in plain language. Avoid adjectives the report does not use, such as “significant” or “dramatic,” unless the report applies them to a measured result. If the report is cautious, keep the caution.

An illustrative example

This example uses a fictional report and is for illustration only. It is not a result from testing a tool.

Fictional report: a 20-page review of a shared office printer contract, with a one-year cost history.

Decision: Should the office renew the printer contract when it expires in January?

Bottom line: The report recommends renewing for one year, with a review at six months. Its cost figures support renewal only if print volume stays near its current level, which the report does not forecast.

Key findings:

Limits: The report uses one year of data. It does not forecast print volume, and it does not compare the contract with other suppliers (page 12).

Next steps: The report recommends a six-month review of printing volume on the two busiest floors (page 13).

The example shows the structure at work. The 14% figure has a unit, a period, and a base. The limits section states what the report does not cover, so the bottom line is not more confident than the evidence.
