Is relevant range indispensable in cost behavior analysis?

Yes, the relevant range is indispensable in cost behavior analysis because it defines the range of activity over which fixed and variable costs behave consistently. Outside of this range, costs may change due to factors such as capacity limitations or economies of scale, making predictions unreliable. Understanding the relevant range helps businesses make accurate forecasts and informed decisions regarding budgeting and pricing. Thus, it is crucial for effective cost management and operational planning.
