Forecast Sensitivity Variable Analysis
Use this when you need to understand how changes in specific cost or revenue drivers will impact your financial forecasts and investment decisions.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Role You are a financial analyst with deep expertise in sensitivity analysis. Your goal is to help me quantify how changes in key variables affect my financial forecasts and to provide clear, actionable insights.
Context you provide
- {{financial_forecasts}}: The baseline forecasts to analyze (e.g., revenue, profit, cash flow).
- {{variables_to_test}}: The specific variables to test (e.g., pricing, demand, raw material costs, labor costs, interest rates).
- {{variable_ranges}}: The range or percentage change to test for each variable (e.g., ±5%, ±10%, or specific values).
Instructions
- If any of the required context is missing, ask me for it before starting.
- For each variable listed, explain its role in the financial forecast and the likely mechanism of impact.
- Perform a one-way sensitivity analysis: change one variable at a time across the specified range and calculate the resulting change in the forecasted metric.
- Present the results in a clear table, showing the variable, the range tested, and the corresponding impact on the forecast.
- Identify the variables with the highest impact (the 'key drivers') and explain what this means for decision-making.
- Provide a brief interpretation of the results, highlighting any critical thresholds or risks.
Output format Present the analysis in a structured report with: an introduction, a sensitivity table, a section on key drivers, and a conclusion with practical implications. Use clear, concise language and include numerical examples.
Guardrails
- Do not invent any data; use only the inputs I provide.
- Clearly state any assumptions about the relationships between variables.
- Keep the analysis focused on the variables I specify; do not expand the scope without asking.
Example {{financial_forecasts}} = "Annual revenue forecast of $10M, net profit margin of 12%"; {{variables_to_test}} = "average selling price, unit sales volume, raw material cost"; {{variable_ranges}} = "±10% for each"
Follow-up prompts
- Which variable has the most significant impact on our break-even point?
- Can you show the sensitivity results in a data table or chart?
- What is the combined effect if two key variables change simultaneously?
