Incremental Analysis, also known as the relevant cost approach or differential analysis, is a vital decision-making method used in managerial economics and finance. This method focuses on evaluating the financial and opportunity costs associated with different alternatives to aid in selecting the best possible option. The primary steps involved in incremental analysis are:
- Gather all costs associated with each alternative.
- Drop the sunk costs.
- Drop those costs that do not differ between alternatives.
- Select the best alternative based on the remaining cost data.
Relevant Cost
Relevant costs, also called differential costs, are costs that differ between decision alternatives. They are crucial in incremental analysis because they directly impact the decision-making process.
Types of Relevant Costs
- Variable Costs: Costs that vary directly with the level of output or activity.
- Fixed Costs: Costs that remain constant within a certain range of activity but may change for different decisions.
- Opportunity Costs: The potential benefit lost by choosing one alternative over another.
Steps in Incremental Analysis
1. Gather All Costs
Collect all the costs associated with each potential decision. This includes both fixed and variable costs, as well as direct and indirect costs.
2. Drop the Sunk Costs
Sunk costs are past costs that cannot be recovered. Since they do not affect future decisions, they are irrelevant and should be excluded from the analysis.
3. Drop Costs That Do Not Differ
Exclude costs that remain the same regardless of the decision alternative. These costs do not affect the comparative analysis and should be ignored.
4. Select the Best Alternative
Evaluate the remaining relevant costs for each alternative. The option with the lowest cost or highest net benefit is typically selected.
Special Considerations
Examples of Incremental Analysis
- Make or Buy Decisions: Deciding whether to produce in-house or to purchase externally.
- Add or Drop a Product Line: Evaluating the financial impact of continuing or discontinuing a product or service.
- Pricing Decisions: Setting optimal prices for products or services by considering variable and fixed costs.
Historical Context
The concept of incremental analysis has been integral to managerial decision-making since its formal introduction in the mid-20th century. Its principles have roots in classical economics and cost accounting.
Applicability in Modern Business
Incremental analysis is used by firms across diverse industries, including manufacturing, retail, services, and technology, to make informed financial decisions.
Comparisons
Incremental vs. Marginal Analysis
While both methods evaluate costs and benefits of decisions, marginal analysis focuses on the additional benefits gained from small changes, whereas incremental analysis compares distinctly separate alternatives.
Related Terms
- Cost-Benefit Analysis: Evaluates the net economic benefits of different choices.
- Break-Even Analysis: Computes the point at which total revenues equal total costs.
FAQs
What is the primary benefit of incremental analysis?
The main advantage is that it simplifies complex decisions by focusing only on costs that change between alternatives.
Why are sunk costs ignored in incremental analysis?
Sunk costs are historical and non-recoverable, hence irrelevant to future decisions.
Can incremental analysis help with pricing strategies?
Yes, it helps by focusing on relevant costs to set competitive and profitable prices.

Summary
Incremental analysis is a systematic approach used to make informed managerial decisions. By focusing on relevant costs and excluding irrelevant or sunk costs, this method simplifies the decision-making process and optimizes financial outcomes for businesses. Its applicability across various business decisions underscores its significance in the realms of economics and finance.
