To calculate the variances for the most recent month, we compare actual results with standard costs. The direct material price variance is -$1,600, and the direct material usage variance is $6,000. The direct labour rate variance is $0, and the direct labour efficiency variance is $6,000. The variable overhead expenditure variance is -$7,500, and the variable overhead efficiency variance is $15,000. The fixed overhead expenditure variance is $19,600, the fixed overhead capacity variance is $10,000, and the fixed overhead efficiency variance is $10,000.
To calculate the variances for the most recent month, we need to compare the actual results with the standard costs. Here are the calculations:
(i) Direct material price variance = (actual price - standard price) * actual quantity = ($1.40 - $1.50) * 16,000 = -$1,600
(ii) Direct material usage variance = (actual quantity - standard quantity) * standard price = (16,000 - 12,000) * $1.50 = $6,000
(iii) Direct labour rate variance = (actual rate - standard rate) * actual hours = ($6.00 - $6.00) * 5,000 = $0
(iv) Direct labour efficiency variance = (actual hours - standard hours) * standard rate = (5,000 - 4,000) * $6.00 = $6,000
(v) Variable overhead expenditure variance = (actual expenditure - standard expenditure) = $75,500 - (4 * 5,000 * $15.00) = -$7,500
(vi) Variable overhead efficiency variance = (actual hours - standard hours) * standard rate = (5,000 - 4,000) * $15.00 = $15,000
(vii) Fixed overhead expenditure variance = (actual expenditure - standard expenditure) = $54,600 - (4 * 4,000 * $10.00) = $19,600
(viii)Fixed overhead capacity variance = (actual hours - standard hours) * standard rate = (5,000 - 4,000) * $10.00 = $10,000
(ix) Fixed overhead efficiency variance = (actual hours - standard hours) * standard rate = (5,000 - 4,000) * $10.00 = $10,000
