Definition§
Sensitivity analysis determines how different values of an independent variable affect a particular dependent variable under a given set of assumptions. It studies how various sources of uncertainty in a mathematical model contribute to the overall uncertainty of the model, helping to highlight which variables have the most impact.
| Sensitivity Analysis | Scenario Analysis |
|---|---|
| Focuses on one dependent variable | Explores multiple outcomes |
| Analyzes variables’ impact tightly | Analyzes a wider framework |
| Often used in financial forecasting | Utilizes various ‘what-if’ scenarios |
| Applicable to specific constraints | Generally takes a broader approach |
Examples§
- Stock Price Prediction: Sensitivity analysis can help predict how changes in interest rates might affect the share prices of publicly traded companies.
- Bond Pricing: Analysts may use sensitivity analysis to understand how different interest rates influence bond prices.
Related Terms§
- Scenario Analysis: A process that analyzes the expected outcome of a scenario and predicts different outcomes based on varying situations.
- What-If Analysis: A decision-making tool that helps in forecasting based on hypothetical input changes.

Frequently Asked Questions§
Q1: What is the primary use of sensitivity analysis?
- A: It’s primarily used to predict how changes in one or more variables affect an outcome in financial modeling and economic scenarios.
Q2: Can sensitivity analysis be applied to personal finance?
- A: Absolutely! You can use it to understand how changing your savings rate could impact your retirement goals.
Q3: What is the difference between sensitivity and scenario analysis?
- A: While sensitivity analysis looks at how changes in one variable affect another, scenario analysis considers multiple changes over many variables to forecast various potential outcomes.
