Goal-seeking analysis
Learning outcome statements
The learning outcome statements relevant for this section are:
- demonstrate an understanding of what-if (or goal-seeking) analysis
Definition of goal seeking analysis
Forward what-if analysis, including sensitivity analysis, changes an input and observes the resulting output; goal-seeking analysis reverses that process by fixing the output you want and solving for the input that gets you there.
Goal-seeking analysis is commonly used in financial planning, budgeting, sales forecasting, and performance optimization. It helps businesses determine the values needed to reach specific objectives, such as achieving a target profit margin, reducing costs, or hitting sales quotas.
Example: Solving for required sales volume
A company sells a product for $50 per unit, with a variable cost of $30 per unit and fixed costs of $200,000. Management wants to know how many units it must sell to reach a target operating income of $100,000.
Set up the equation:
Solve for : , so .
Answer: 15,000 units. In Excel’s goal seek function, this sets the operating income cell to $100,000 by changing the units-sold cell.
Applications of goal-seeking analysis
- Financial planning: Businesses use goal-seeking techniques to determine pricing strategies, break-even points, and investment targets.
- Sales and marketing: Companies use this analysis to estimate the required advertising budget needed to achieve a particular sales volume.
- Project management: Project planners can apply goal-seeking analysis to determine the necessary resource allocation to complete a project within a specified timeframe.
- Cost targets: Organizations use this approach to determine the cost reduction needed to reach a specified margin or profit target.
Tools for goal-seeking analysis
Goal-seeking analysis can be performed using various software tools, including:
- Microsoft Excel goal seek function: A built-in feature that allows users to adjust one input to achieve a specific output.
- Financial modeling softwares: Programs like MATLAB, R, and Python (using optimization libraries) enable advanced goal-seeking analysis in complex financial models.
- Enterprise resource planning (ERP) systems: Many ERP platforms incorporate goal-seeking capabilities to assist in strategic decision-making.
Limitations of goal-seeking analysis
- Goal seek adjusts only one input at a time; problems with multiple unknowns need optimization tools such as Excel Solver.
- The result is only as good as the model’s assumed relationships, which are often simplified and may ignore interdependencies between variables.
- It shows whether a target is reachable, not whether it’s realistic - cutting expenses to hit a margin target can hurt quality or future revenue.
- It gives a single answer, not probabilities; use simulation models, such as Monte Carlo simulation, for a range of likely outcomes.
