Build cleaner financial models, communicate results to non-finance audiences, and speed up analysis without sacrificing rigor. Built across 4 distinct stages covering Model Architecture, Forecasting and Assumptions, Communication and Presentation and more, this guide gives you one tested prompt per step so you never have to write from scratch or guess what the AI needs. The prompts work in ChatGPT, Claude, and Gemini and are designed to get usable output on the first try.

Stage 1

Model Architecture

Design the structure and logic of your financial model before building it.

Build three-statement financial model

I need to build a three-statement financial model for [DESCRIBE BUSINESS TYPE]. Walk me through the architecture: what goes in the income statement, balance sheet, and cash flow statement, and how the three statements link together.

Model Architecture

Design revenue model

Design a revenue model for [DESCRIBE BUSINESS MODEL, E.G. "A SAAS COMPANY WITH MONTHLY AND ANNUAL SUBSCRIPTIONS AND PROFESSIONAL SERVICES"]. Define the revenue drivers, how to structure the input assumptions, and how to calculate MRR, ARR, and churn.

Model Architecture

Build unit economics model

I need to build a unit economics model for [DESCRIBE BUSINESS]. Define the key unit metrics (CAC, LTV, payback period, contribution margin), how to calculate each, and what assumptions are most sensitive.

Model Architecture

Explain how

Explain how to structure a driver-based model vs a line-item model for [DESCRIBE USE CASE]. Which approach is better for my situation and what are the practical trade-offs in terms of flexibility and maintainability?

Model Architecture

Building model

I am building a model with multiple business segments: [LIST SEGMENTS]. How should I structure the model so each segment can be modeled independently but roll up cleanly into consolidated financials?

Model Architecture

Stage 2

Forecasting and Assumptions

Build defensible forecasts with clearly stated assumptions.

Write assumptions section

Write the assumptions section for a financial model projecting [DESCRIBE BUSINESS] over 3 years. Cover revenue growth drivers, margin assumptions, headcount, capex, and working capital, with notes on how each assumption was derived.

Forecasting and Assumptions

Build bottoms-up revenue forecast

I need to build a bottoms-up revenue forecast for [DESCRIBE SALES MOTION]. Define the pipeline stages, conversion rates, deal sizes, and sales cycle length needed to project bookings for the next 4 quarters.

Forecasting and Assumptions

Create scenario framework

Create a scenario framework for this model: [DESCRIBE MODEL]. Define the assumptions that differ between base, upside, and downside scenarios, and build a toggle so stakeholders can switch between scenarios easily.

Forecasting and Assumptions

Top-down market sizing

I have a top-down market sizing model and a bottoms-up sales capacity model that produce different revenue numbers. Help me reconcile them and decide which should anchor the forecast.

Forecasting and Assumptions

Write sensitivity analysis section

Write the sensitivity analysis section for this model. The key outputs are [DESCRIBE OUTPUTS]. Identify the 5 inputs with the most impact, build a two-variable data table for each, and write the interpretation.

Forecasting and Assumptions

Stage 3

Communication and Presentation

Explain financial results and models to non-finance audiences.

Write executive summary

Write an executive summary of these financial projections for a non-finance audience: [PASTE KEY OUTPUTS]. Explain the key assumptions, what drives the results, and the most important risks to the forecast in plain language.

Communication and Presentation

Business partner is

A business partner is questioning why our margin is declining in year 2: [DESCRIBE MODEL DYNAMICS]. Write a clear explanation of the drivers, using plain language and concrete examples rather than accounting jargon.

Communication and Presentation

Present three funding scenarios

I need to present three funding scenarios to our board: [DESCRIBE SCENARIOS]. Write the narrative for each scenario that explains the investment required, what it buys, and the expected financial outcome.

Communication and Presentation

Write model documentation

Write the model documentation for [DESCRIBE MODEL]. Include a purpose statement, input description, key formula explanations, known limitations, and instructions for updating assumptions.

Communication and Presentation

Communicate budget variance

I need to communicate a budget variance to the leadership team. We are [OVER/UNDER] on [BUDGET LINE] by [AMOUNT] due to [REASON]. Write the variance explanation memo that is direct, not defensive, and focuses on resolution.

Communication and Presentation

Stage 4

Specific Model Types

Build models for common finance use cases.

Walk me

Walk me through building a DCF valuation model for [DESCRIBE COMPANY TYPE]. Cover the free cash flow projection, terminal value calculation, WACC derivation, and how to sanity-check the output.

Specific Model Types

Build LBO model

I need to build an LBO model for [DESCRIBE TARGET COMPANY]. Explain the structure, how to model the debt schedule, the equity waterfall, and how to calculate IRR and MOIC for different leverage scenarios.

Specific Model Types

Design headcount

Design a headcount and compensation model for [DESCRIBE COMPANY, N EMPLOYEES]. Include current headcount, planned hires by quarter, role-level salary bands, loaded cost multiplier, and how to flag budget vs actual variance.

Specific Model Types

Build working capital model

Build a working capital model for [DESCRIBE BUSINESS]. Define the key working capital metrics (DSO, DPO, DIO), how to calculate cash conversion cycle, and how changes in each metric affect free cash flow.

Specific Model Types

Model pricing changes

I need to model the impact of pricing changes on our P&L. Current pricing is [DESCRIBE]. I am considering [DESCRIBE PRICING CHANGE]. Build the analysis showing revenue, volume, mix, and net impact under three elasticity assumptions.

Frequently asked questions

Can ChatGPT help me design a financial model architecture?+

Yes. Describe your business model and use case and ChatGPT will walk you through the model structure, revenue driver logic, how statements link, and where to place key assumptions.

How useful is ChatGPT for building revenue forecasts?+

Very useful for structuring the logic. ChatGPT can walk through bottoms-up sales capacity models, SaaS cohort models, and market sizing approaches with defensible assumption frameworks.

Can ChatGPT explain financial model outputs to non-finance audiences?+

Yes. Paste your key outputs and ChatGPT will write clear, jargon-free explanations of results, drivers, and risks that work for board decks, leadership updates, or business partner conversations.

What types of financial models does ChatGPT handle best?+

Three-statement models, unit economics, revenue drivers, DCF valuation, headcount planning, and working capital models are all areas where ChatGPT provides accurate, structured guidance.

Can ChatGPT help me build scenario analysis?+

Yes. Describe your model and ChatGPT will define base, upside, and downside scenario assumptions, build a toggle structure, and write sensitivity analysis interpretation for the key outputs.
