Sunk Costs

What are Sunk Costs?

Sunk costs, also known as sunk capital, represent expenditure that has already been incurred and cannot be recovered. Once these costs are incurred, they are often included in the books of account as an asset, even though their value is non-recoverable. In management accounting, sunk costs are irrelevant to any subsequent business decisions because they remain constant regardless of potential future outcomes.

Detailed Explanation

Sunk Capital: This is typically expenditure on capital items that, once incurred, are recorded as assets even though their value cannot be recovered. Examples include constructing a railway embankment or dredging to create a berth in a harbor.
Management Accounting: In this context, sunk costs refer to costs that have already been incurred and are non-recoverable. Such costs should not influence future business decisions. A classic example is the original purchase price of a machine when deciding whether to replace it.

Examples of Sunk Costs:

Infrastructure Projects: Costs related to large-scale infrastructure projects, such as building bridges or highways, which cannot be recovered once the project is complete.
Marketing Expenses: Money spent on advertising campaigns that have already run.
Research and Development: The expenditure incurred in the development of a new technology or product which is abandoned or failed.
Equipment Purchases: The original cost of machines or equipment where the decision is being made about their replacement.

Frequently Asked Questions (FAQs):

Q1: How do sunk costs affect decision-making? A1: Sunk costs should not affect decision-making as they are past costs and cannot be recovered. Future decisions should be based on relevant costs and potential benefits.

Q2: Can sunk costs be recovered? A2: No, by definition, sunk costs cannot be recovered. They are expenses that have been made and are non-recoverable.

Q3: Are sunk costs recorded in financial statements? A3: Yes, they can be recorded as assets in the books of account, even though their value cannot be recovered.

Q4: Why are sunk costs irrelevant in future decisions? A4: Because they do not change regardless of the outcome of a decision. Only future costs and benefits should be considered in decision-making.

Q5: How do sunk costs differ from fixed costs? A5: Sunk costs are past expenditures that cannot be recovered, while fixed costs are ongoing expenses that do not change with the level of output or sales.

Relevant Cost: Costs that will be affected by a decision and should be considered when making future business decisions.
Fixed Costs: Regular, ongoing expenses that remain constant regardless of the level of production or sales.
Opportunity Cost: The potential benefits an individual, investor, or business misses out on when choosing one alternative over another.
Variable Costs: Costs that vary directly with the level of production or sales volume.
Capital Expenditure: Funds used by an organization to acquire, upgrade, and maintain physical assets such as property, buildings, or equipment.
