Which of the following is NOT classified as a type of expense variance?

The choice of "Stepped Variance" is correct as it is not classified as a type of expense variance. In financial analysis, expense variances typically refer to differences between expected and actual expenses, and common types include price variance, volume variance, and efficiency variance.

Price variance measures the impact of the difference between the actual price paid for inputs and the expected or standard price. Volume variance focuses on the discrepancies arising from the actual quantity of inputs used compared to the planned quantity. Efficiency variance assesses how efficiently resources are utilized, comparing actual outputs to expected outputs based on the resources consumed.

"Stepped Variance" is not a recognized category in this context. It does not represent a standard measure used to analyze variations in expenses, making it distinct from the other options that all relate directly to expense variance analysis. Recognizing these classifications is crucial for understanding cost control and financial management within an organization.
