What is the relevant range?

• A. The range of output where total costs are linear.
• B. The activity levels the organization has experience at, for which cost data is available.
• C. The maximum capacity of the production facility.
• D. The point at which fixed costs become variable.

Answer: (B)

The relevant range is the band of activity levels over which cost behavior is expected to stay the same and for which we have cost data to base estimates on. Within this range, fixed costs are treated as constant and variable costs per unit remain unchanged, so total costs change proportionally with activity. This concept ties directly to the organization’s actual operating experience—the activity levels for which data exist and plans are made. If you operate outside this range, costs can change in unforeseen ways, making estimates unreliable. The best choice describes the relevant range as the activity levels the organization has experience at, for which cost data is available. The other statements aren’t accurate definitions: relevance isn’t simply about where total costs are linear, nor is it tied to maximum capacity, and it isn’t about the point where fixed costs become variable.
