What is a Sensitivity Analysis – Example and Components involved
SENSITIVITY ANALYSIS
A Sensitivity Analysis is a “what-if” tool that examines the effect on a company’s Net Income (bottom line) when sales levels are increased or decreased. For example, the sensitivity analysis can answer the following questions:
- “WHAT” would be my forecasted net income, “IF” my sales forecast is 30%, 20%, or 10% too high?
- “WHAT” would be my forecasted net income, “IF” my sales forecast is 30%, 20% or 10% too low?
In other words;
- What would my bottom line be if I sold 10% more units than I originally forecasted?
- What would my bottom line be if I sold 20% more units than I originally forecasted?
- What would my bottom line be if I sold 30% more units than I originally forecasted?
- What would my bottom line be if I sold 10% fewer units than I originally forecasted?
- What would my bottom line be if I sold 20% fewer units than I originally forecasted?
- What would my bottom line be if I sold 30% fewer units than I originally forecasted?
Below provides an example of a sensitivity analysis.

A sensitivity analysis consists of three main components namely; 1) The Heading, 2) Sales Percentage Factors, and 3) The Body. Below briefly explains each component; beginning with The Heading.
STEPS TO DEVELOP A SENSITIVITY ANALYSIS ARE SUMMARIZED BELOW:
- develop your forecasted income statement;
- set your sales percentage factors (10%, 20%, and 30% for instance); look at each cost & expense and determine which is a variable cost and which is a fixed cost;
- Increase & decrease the sales in dollars at the various sales percentage (%) factors;
- Increase & decrease the variable costs at the various sales percentage (%) factors;
- The fixed costs will remain the same at various sales increases & decreases;
- Subtract each column’s variable costs and fixed costs from each sales column to arrive at the net income before tax at the various sales increases & decreases;
- Apply a tax rate to the net income before taxes to arrive at the Net Income After Taxes (optional).
Don’t get frustrated when distinguishing between a variable cost and a fixed costs. All you have to do is ask yourself – “will this cost or expense increase or decrease if I sell one additional unit or sell one fewer unit?” If the answer is yes, then it’s a variable cost AND if the answer is no, then it’s a fixed cost.
