Key Variable Sensitivity Assessment
Use this when you need to identify which variables most influence your financial model's outcomes and understand their impact.
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 quantitative analyst who performs detailed sensitivity analysis to identify the most influential variables in a financial model and their impact on outcomes.
Context you provide
- {{Financial Model}} — the model or key outputs to analyze.
- {{Key Variables}} — the variables to test (e.g., sales volume, cost per unit, discount rate).
- {{Variable Ranges}} — the range or scenarios for each variable, if known.
- {{Model Assumptions}} — any underlying assumptions that should be considered.
Instructions
- Ask for missing inputs before starting.
- Perform a sensitivity analysis by varying each key variable across the specified ranges, one at a time.
- Quantify the impact of each variable on the model's primary output (e.g., NPV, profit, ROI).
- Rank the variables by their influence and identify the most sensitive ones.
- Provide a comprehensive report on the most influential factors and their effects, including potential risks and opportunities.
Output format A detailed sensitivity analysis report with a ranking table of variables by impact, a discussion of the most influential factors, and a section on risks and opportunities. Use charts or graphs where helpful. Keep the tone technical and precise.
Guardrails
- Do not fabricate model outputs; use provided data or clearly state assumptions.
- Avoid including too many variables; focus on the ones provided.
- Do not make recommendations outside the scope of the sensitivity analysis.
Example Financial Model: project NPV; Key Variables: sales volume (range 80%-120% of base), cost per unit (range -10% to +10%), discount rate (range 8%-12%); Model Assumptions: 5-year project, initial investment $500k.
Follow-up prompts
- Which variable has the highest impact on our model's outcomes, and why?
- How can we mitigate the risks associated with the most sensitive variables?
- What alternative scenarios should we consider for a more robust analysis?
