Quick Answer

Define the key variables and assumptions for your base upside and downside scenarios. Paste into Claude or ChatGPT. Get a structured three-scenario model with financial outcomes and strategic implications.

What You Get

A complete three-scenario financial model covering base upside and downside assumptions, financial outcomes for each scenario, probability-weighted expected case, key trigger points that shift between scenarios, and strategic recommendations for each.

Who Is This For

CFOs presenting scenario analysis to boards and investors, finance teams stress-testing financial plans, and startup founders planning for multiple fundraising outcomes.

About This Template

Scenario planning forces leaders to confront uncertainty rather than pretend the future is knowable. A three-scenario model β€” base, upside, and downside β€” gives boards and management teams the context to make better decisions under uncertainty. This template guides finance teams through defining the key variables that drive each scenario, then uses AI to produce a structured three-scenario model with financial outcomes, probability-weighted expected case, and strategic implications for each scenario.

Generate three-scenario financial model

Paste this prompt into Claude or ChatGPT with your inputs filled in.

You are a CFO building a three-scenario financial model for board and management review. Using the inputs below, produce a structured scenario analysis.

Company: [company_name]
Planning period: [planning_period]
Base case revenue: [base_revenue]
Upside driver: [upside_driver]
Downside driver: [downside_driver]
Base case costs: [base_cost]
Current cash: [current_cash]
Scenario probabilities: [scenario_probabilities]

Produce:
1. Base Case β€” revenue, costs, EBITDA, and cash position with full assumptions
2. Upside Case β€” 20-30 percent revenue premium over base with upside-specific assumptions
3. Downside Case β€” 20-30 percent revenue shortfall from base with downside assumptions and cost response
4. Financial Outcomes Table β€” side-by-side comparison of revenue, EBITDA, and year-end cash for all 3 scenarios
5. Probability-Weighted Expected Case β€” weighted average outcome based on stated probabilities
6. Scenario Trigger Points β€” specific metrics that would signal a shift from base to upside or downside
7. Strategic Recommendations β€” what management should do differently in each scenario

Be specific about the financial numbers in each scenario. The downside case must include a cost response plan.

Sample Output

This is an example of what AI produces when you use this template.

Financial Outcomes Table

Base case: Revenue $14.25M, EBITDA $1.75M (12.3 percent margin), Year-end cash $4.1M. Upside case: Revenue $17.1M (20 percent above base), EBITDA $3.6M (21 percent margin), Year-end cash $6.3M. Downside case: Revenue $11.4M (20 percent below base), EBITDA -$1.1M (negative), Year-end cash $1.8M. Probability-weighted expected case: Revenue $13.98M, EBITDA $1.22M, Year-end cash $3.8M.

Downside Strategic Recommendations

If revenue tracks 10 percent below base by end of Q1 β€” activate the downside response immediately: freeze all non-essential hiring (save $480K annual), cut discretionary marketing spend by 40 percent (save $360K), and renegotiate or defer any software contracts over $20K annual. These actions bring the downside EBITDA from -$1.1M to approximately -$200K β€” preserving sufficient cash to reach profitability without raising capital. Trigger point: if March MRR is below $950K, activate downside plan on April 1.
