ACCA · Question 28 · Standard Costing

A logistics warehouse pays its workers a standard rate of $15 per hour. During the week, workers were paid for 5,000 hours, but due to a conveyor belt breakdown, they only actively worked for 4,800 hours.

Calculate the idle time variance. State your answer as a number followed by 'A' or 'F' (e.g., 3000 A).

How to approach this question

1. Calculate the idle hours (Hours paid - Hours worked). 2. Multiply idle hours by the standard labor rate. Idle time is always adverse.

Full Answer

Idle hours = Hours paid - Hours worked = 5,000 - 4,800 = 200 hours. Idle time variance = 200 hours × $15/hour = $3,000. Because idle time represents paid time where no work was done, it is always Adverse.

Common mistakes

Calculating the efficiency variance instead of the idle time variance.
