WebMar 20, 2024 · Sensitivity analysis helps to identify and evaluate the risks associated with an investment or project. By testing the model with different assumptions, financial analysts can determine how sensitive the output is to changes in key variables, such as interest rates, exchange rates, or sales volumes. WebThe formula for sensitivity analysis is basically a financial model in excel where the analyst is required to identify the key variables for the output formula and then assess the output based on different combinations of the independent variables. Mathematically, the dependent output formula is represented as, Z = X2 + Y2
