Incremental Analysis: Definition – Explanation – Example

What Is Incremental Analysis?

Incremental AnalysisIncremental analysis is a business decision-making tool that examines alternative choices based on marginal cost differences between them. Incremental analysis is used in business to determine the true cost difference between alternatives.

This technique is also known as the relevant cost method, marginal analysis, or differential analysis.  Simply put, it disregards any sunk or prior costs. Incremental analysis is important in company planning. For example,  deciding whether to self-produce or outsource a function. Companies use this tool to determine whether to accept new business, manufacture, or purchase items.  Also, to sell or process products further, discontinue a product or service, and allocate resources. Only two courses of action are considered and the comparison is based on the differences rather than commonalities.

Incremental Analysis  – A Closer Look

Incremental analysis is a problem-solving method that uses accounting data to make decisions. When one alternative is compared to another, incremental analysis can reveal the advantages or various consequences.

Relevant Versus Non-Relevant Costs

Only relevant expenses are included in analysis models.  Further, these costs are often divided into variable and fixed costs. To ensure that the organization pursues the most advantageous choice, the analysis examines opportunity costs.  This is the lost or wasted opportunity when choosing one alternative over another. Non-relevant sunk costs are expenses that have already been incurred. Because sunk costs are unaffected by any action, they are not considered in the incremental analysis. Relevant expenses are sometimes known as incremental costs since they are only incurred when relevant activity is expanded or commenced.

Types of Incremental Analysis Decisions

Incremental analysis assists businesses in determining whether or not to accept customized orders. Customized orders may turn out to be less expensive than the regular selling price. Incremental analysis also aids in allocating limited resources to multiple product lines.  It can help to guarantee that a scarce asset is utilized to its full potential. Decisions on whether to manufacture or purchase items, abandon a project, or rebuild an asset benefit from an incremental study of the opportunity costs. Incremental analysis also determines if a product should be processed further in-house or sold at an earlier stage in the production process.

  • New business – Taking on or accepting a new line of business
  • Make or buy – Making or buying parts of a product and/or manufacturing the product
  • Point of processing – Selling unfinished or raw products and/or processing them further
  • Continue or abandon – Eliminating an unprofitable division or segment of the business
  • Resource allocation – Determining a sales mix

Incremental Analysis – Key Considerations

The three main concepts to consider are differential cost, sunk cost, and opportunity cost.

  • Differential costs are the expenses and revenues that differ across options.  They exclude revenues and costs that are shared by all alternatives. In certain research or writings, the income created by different options is referred to as relevant benefits. Therefore, these are also known as unnecessary expenses or marginal costs. A cost must be incremental, result in a change in cash flow, and be expected to alter in the future to be regarded as a relevant expense. As a result, a relevant cost occurs as a result of a certain management choice. The notion is not applicable to financial accounting but is applicable to management accounting.
  • Sunk costs refer to expenditures that have already been incurred.  Therefore, they have no bearing on any management decision or choice between alternatives. The amount is unlikely to rise or decrease entirely in the future. Sunk costs are often referred to as sunk capital, embedded cost, or past year cost.
  • Opportunity cost defines the gain or loss arising from a choice between two possibilities. The opportunity cost is the value of what is lost while choosing between two or more possibilities. As a result, opportunity cost is defined as “the loss incurred in order to achieve a certain benefit.” Or, the exchange of one benefit for another.

Example of Incremental Analysis

Consider a company that manufactures a particular product and sells at a net profit margin of 25%. The company currently runs at less than full capacity – about 75%.  The company receives an inquiry for a similar product with a net profit margin of 15%. The sales manager is considering rejecting the potential order because of a policy to only accept orders with a net profit margin of 20% or higher.  However, if the company at full capacity can still supply the product, it may lead to a higher margin than its forecasted 15%.

This is due to the fact that fixed expenditures will remain constant.  Therefore, when an additional item is created, the firm will not incur any further expenses beyond the variable costs. As a result, it may become a valid production item with a net profit above the 20% threshold.  The finance manager must perform an incremental cost analysis before deciding whether to accept or reject the potential order.

Form 8857Form 8857 is an IRS Tax Form requesting innocent spouse tax relief.  It is used by taxpayers to seek relief from a tax burden involving a spouse or ex-spouse. Couples who file a combined tax return are generally jointly liable for any tax due. When additional taxes are discovered due to undeclared income and incorrect deductions or credits, both partners are accountable. This liability can remain in place even after a couple has divorced.

Getting a divorce doesn’t necessarily stop the IRS.  Once you file a joint tax return, they consider both parties still liable for a tax obligation.  Even though a divorce ruling may indicate that only one party is accountable for the tax.  The IRS may nevertheless assume that both parties maintain joint liability for the tax debt. If there is a balance owed, a spouse or ex-spouse must normally submit Form 8857 within the prescribed time limit the IRS has to collect the tax.  The application for innocent spouse relief must usually be completed no later than 2 years after the date the IRS first attempted to collect the taxes in question from you.
