In one sentence
An avoidable cost is an expense that would disappear if a specific activity, product, or decision were discontinued, so it matters for incremental decision-making.
Decision rule (incremental analysis)
A common short-run decision rule is:
[
\text{Proceed if incremental revenue} \ge \text{avoidable cost}
]
Sunk costs are not avoidable and should not affect the decision.

Background
The concept of avoidable cost is a pivotal term in economic and financial analysis, helping firms and policymakers understand the implications of halting production or abandoning a project. A clear definition and comprehension of avoidable costs enable better decision-making when planning budgets, evaluating opportunities, or considering discontinuing operations.
Historical Context
The study of avoidable costs has been integral since the evolution of cost accounting principles in the early 20th century. It gained prominence as businesses sought more accurate methods to allocate resources and manage operational efficiency.
Definitions and Concepts
Avoidable cost refers to:
- Definition: That part of the cost of any output that could be saved by not producing it. It includes direct variable costs like fuel, materials, and labor tied explicitly to the production process.
- Common Misconceptions: Some costs which may seem avoidable at first glance can sometimes prove otherwise due to contractual obligations or legal constraints, such as long-term contracts for materials or labor law requirements for notice periods.
- Fixed Cost: Costs that do not vary directly with the level of production or operation.
- Variable Cost: Costs that vary directly with changes in production volume.
- Sunk Cost: Costs that have already been incurred and cannot be recovered.
- Marginal Cost: The cost to produce one additional unit of output.
