What is the relevant range in cost behavior?

The relevant range in cost behavior refers to the specific volume of activity over which fixed costs remain constant. Understanding this concept is crucial for analyzing how costs behave at different production levels. Within this relevant range, fixed costs do not change with the volume of production, meaning that they will be the same regardless of whether a business produces a small quantity or a larger quantity of goods, as long as that production level falls within the defined relevant range.

When the volume of production exceeds this relevant range, fixed costs may begin to change, which could happen due to the need for additional facilities or equipment. Therefore, recognizing the relevant range helps businesses make informed decisions regarding budgeting, forecasting, and pricing, without worrying about unexpected cost increases outside of this range.
