AI financial modeling

Build the model logic without hiding the assumptions.

Use Griddy to structure or complete an Excel model, connect labeled assumptions to formulas, add forecast and ratio outputs, and preserve actuals or protected tabs. You provide and validate the financial inputs.

Griddy can accelerate workbook construction and repair. It does not verify external financial data, approve assumptions, or replace independent review of a consequential model.

Concrete modeling prompt

“Complete the forecast without changing the 2024A actual column. Forecast EBITDA from Revenue and the EBITDA Margin assumption, calculate EBIT after D&A, Taxes from EBIT and the tax-rate assumption, and PAT after taxes. Add EBITDA Margin and Net Margin on the Ratios sheet, keep Assumptions unchanged, and format forecast values as currency and percentages.”

This request separates actuals from forecast periods, identifies assumption links, states the formula logic, names protected sheets, and specifies number formats.

Expected output

  • Forecast formulas connected to labeled assumption cells rather than hard-coded results.
  • EBITDA, EBIT, Taxes, and PAT calculated across the forecast periods.
  • Ratio formulas tied back to forecast Revenue, EBITDA, and PAT.
  • Actuals, assumptions, layout, and unrelated sheets preserved.

A correct formula can still reflect a weak assumption. Reconcile actuals, verify sources, stress the drivers, and have a qualified reviewer inspect the finished model.

Workflow

From request to workbook.

  1. 01

    Define the decision

    Start with the question—runway, hiring, pricing, budget, investment, capacity, or cash—and only include the detail needed to support that decision.

  2. 02

    Separate inputs and logic

    Put verified assumptions in labeled cells, preserve historical actuals, and describe which forecast lines and ratios should reference each driver.

  3. 03

    Build or repair formulas

    Ask Griddy to fill the forecast ranges, connect sheets, apply number formats, and preserve specified headers, actuals, notes, and assumption cells.

  4. 04

    Audit and stress-test

    Trace formulas, reconcile totals, check signs and timing, change key assumptions, and confirm that base, upside, and downside cases behave as intended.

Model construction

Make the drivers visible and the formulas inspectable.

Financial modeling is distinct from formula generation because the model also needs structure, assumptions, period logic, scenario behavior, and reviewer trust.

01

Forecast schedules

Connect revenue, margins, payroll, operating expenses, taxes, working capital, or cash lines across monthly or annual forecast periods.

02

Ratios and scenarios

Build driver-based margins and ratios, then create base, upside, and downside outputs by changing labeled assumptions rather than rewriting formulas.

03

Formula-level control

Specify cross-sheet references, absolute assumption cells, preserved actuals, error guards, and target number formats for each model range.

Review before you rely

Treat the model as a decision system.

The workbook should make it easy to answer where a number came from, which assumption moves it, and what breaks under a different scenario.

  • Verify source data and label the date, unit, and provenance of every material input.
  • Separate historical actuals, assumptions, forecast formulas, and outputs so reviewers can trace the model.
  • Check signs, units, period alignment, cash timing, circular references, and denominator guards.
  • Use independent review for material financial, investment, lending, tax, or board decisions.

FAQ

Before you start.

Can Griddy build a financial model in Excel?

Griddy can help create model structure, formulas, formatting, summaries, charts, and multi-sheet forecast logic. You need to provide verified inputs and review the financial assumptions and outputs.

Can it complete an existing model without changing actuals?

Yes. Name the forecast ranges, formula rules, protected actual columns, assumption cells, and untouched sheets. Clear preservation instructions make the requested final state easier to verify.

Does Griddy provide financial data?

Do not assume generated or externally sourced values are authoritative. Provide and verify the source data used in a consequential model, and record its provenance in the workbook.

What should I review before using the model?

Trace formulas, reconcile historical periods, check units and signs, test scenarios, inspect cash timing and circular references, and obtain qualified independent review for material decisions.

Keep the logic open to inspection.

Connect verified assumptions to formulas, then stress-test the workbook before relying on it.
