Gemini for Financial Analysis: Sources, Sheets, and Review

Use Gemini for financial analysis to read supplied documents, help build spreadsheet calculations, and explain results you have checked. Keep document extraction separate from calculation: finding a number in a report and calculating a margin are different tasks with different checks.

The ongoing work needs a record of assumptions and approvals as well as numbers. fenbs keeps those human decisions, source references, and unresolved review tasks available outside one AI conversation. Your source reports and working financial model still belong in the tools used to maintain them.

How do you set up a financial analysis workflow?

1. Define the question and audience. For example: Explain the change in operating margin between two completed reporting periods for an internal review.
2. Collect approved sources. Record the issuer, reporting period, publication date, currency, units, and whether a newer or restated version exists.
3. Ask Gemini to extract the relevant figures with their table names and page references. Verify the extracted numbers against the documents.
4. Calculate in a working spreadsheet. Keep source inputs, formulas, and scenario assumptions in separate labeled areas.
5. Review the result before drafting the narrative. Save the checks, unresolved differences, and the person responsible for approving the conclusion.

Use an approved account and sharing process before providing confidential financial material. Start with public filings or a limited internal extract when possible. The aim is to give Gemini enough information to answer a defined question, rather than a collection of files whose status is unclear.

When should you use documents, chat, or Sheets?

Google supports uploading and analyzing files in Gemini Apps↗ (opens in a new tab). That is useful for asking questions about a supplied report. Google also documents Gemini in Google Sheets↗ (opens in a new tab), including formula creation, charts, and analysis. Consult those guides for current access and file requirements.

For a research notebook centered on source documents, see the Gemini Notebook guide. For broader dataset preparation, use Gemini for data analysis; this workflow concentrates on financial sources, assumptions, and review.

How do you stop extracted figures from losing their meaning?

Require a source ledger before asking for conclusions. For every input, retain the metric name as reported, period, units, currency, document version, and location. A figure labeled in thousands must not silently become a figure in dollars when copied into a spreadsheet.

Do not treat similarly named measures as interchangeable. The SEC financial statement guide↗ (opens in a new tab) explains the different roles of balance sheets, income statements, and cash flow statements. Match point-in-time balances with the appropriate dates, and period-based figures with comparable reporting periods.

Use only the supplied financial report. Find revenue and operating income
for each reporting period shown. Return: reported label, value, units,
currency, period, table name, and page reference.
Flag restated or adjusted figures separately.
If the report does not provide a value, write "not found".
Do not calculate ratios or explain the business performance yet.

Check each extracted input against the source, including parentheses that indicate negative values. If the document contains both reported and adjusted measures, preserve the distinction. Ask the reviewer which definition serves the question instead of allowing the narrative to decide it.

How should you check calculations and assumptions?

Ask for an inspectable formula, not just a number described as calculated. Confirm that the referenced cells contain the intended periods and measures. Test the formula on simple values you can calculate yourself before using it across a larger model.

• Reconcile totals with the source statements and explain any difference before using the result.
• Check signs, units, currencies, and whether a comparison uses a quarter, a year, or another period.
• Keep actual figures separate from estimates, forecasts, and scenario inputs.
• Define percentage change and percentage-point change separately in the output.
• Test missing values and zero denominators instead of accepting a convenient replacement value.

For a hypothetical example, a margin moving from 10% to 12% rises by two percentage points. Calling that a 2% increase changes the meaning. Give Gemini the checked calculation and ask it to explain that exact result, including the terminology you want used.

Record the assumptions a person selected in fenbs Decisions and rules, with their scope and reason. An assistant can record the choice; it should leave an unresolved accounting or modeling question open for the appropriate person.

What belongs in the final financial summary?

Separate findings, interpretation, and open questions. A finding might be a checked change in a reported measure. An interpretation proposes why it changed and needs evidence from disclosures or other approved sources. An open question says what the available material cannot establish.

Ask Gemini to attach a source reference to each factual sentence and identify claims that go beyond the supplied evidence. Then open the references yourself. A citation is useful only if it supports the particular sentence, period, and definition you are using.

Have a responsible reviewer approve the report for its intended use. A polished explanation does not establish that the underlying accounting treatment, forecast, or investment judgment is suitable. The broader AI financial analysis guide covers choosing a workflow across tools.

How to do this with fenbs

1. Create a free account and add a project naming the analysis question, reporting periods, and reviewer.
2. Keep a source reference list with the report locations and versions. Add definitions that future sessions need to the project glossary.
3. Record approved modeling choices in Decisions and rules. Create separate tasks for reconciliation, formula review, and open questions.
4. Connect a supported assistant through Integrations. Ask it to read the context before work and save the checked findings and next review step in Where we left off.

fenbs does not calculate your financial model or connect to Google Sheets. It is useful for the decisions and follow-through around the analysis; a one-time calculation may need only a reviewed workbook. See Gemini for project management for ongoing work and the AI at work hub for related guides.
