Definition
Sensitivity Analysis is a technique used in financial modeling to determine how different values of an independent variable affect a particular dependent variable under a given set of assumptions. This method is commonly used to assess the risks and potential impacts of changes in key input variables on the outcome of a decision or project.
Examples
-
Investment Risk Assessment: Financial analysts use sensitivity analysis to assess how changes in interest rates or market conditions could impact the returns on an investment portfolio.
-
Project Management: Project managers apply sensitivity analysis to identify how changes in project timelines and budgets can influence the overall feasibility and profitability of a project.
-
Sales Forecasting: Companies perform sensitivity analysis to see how changes in market demand, supplier costs, or other factors can affect sales forecasts and business operations.
Frequently Asked Questions (FAQ)
What are the main benefits of sensitivity analysis?
Sensitivity analysis helps assess risk, identify critical variables, test models’ robustness, and support decision-making processes.
It involves changing one input at a time and observing the effect on the output while keeping other variables constant.
What is the difference between sensitivity analysis and scenario analysis?
Sensitivity analysis examines changes in one variable at a time, while scenario analysis evaluates the impact of changing multiple variables simultaneously.
Can sensitivity analysis be applied in non-financial scenarios?
Yes, it can be applied to any field requiring risk assessment and decision-making, such as engineering, medicine, and environmental studies.
Tools include spreadsheet software like Microsoft Excel, specialized financial modeling software, and statistical packages like R and Python.
-
Scenario Analysis: A process of analyzing possible future events by considering different plausible scenarios.
-
Risk Assessment: The identification and evaluation of risks associated with a particular course of action or decision.
-
Monte Carlo Simulation: A computational technique used to model the probability of different outcomes by running multiple trials using random variables.
-
Break-Even Analysis: A financial calculation to determine the level at which a business must operate to cover its costs.
