Variance Analysis Flashcards
What are the three material variances and their definitions?
Total variance
Difference between actual and standard direct material costs of the output produced
Material Price variance
(actual quantity of material purchased x standard price) – actual cost of material purchased
Material Usage variance
(actual production x standard material cost per unit) – (actual material used x standard cost per unit of materials)
What are the three labour variances and their definitions?
Total variance
Difference between the actual and standard direct labour costs of the output produced
Direct labour rate variance
(actual hours paid x standard labour rate per hour) – (actual hours paid x actual direct labour rate per hour)
Direct labour efficiency variance
( actual production in standard hours x standard direct labour rate per hour) – (actual direct labour hours worked x standard direct labour rate per hour)
How do you calculate labour variances?
Labour rate variance £ Actual hours @ standard price Actual cost Labour efficiency variance hours Actual units should have used x ? hours Actual units did use X standard hourly rate £
What are ideal time variances?
Idle time is where the workforce aren’t working
If there is idle time this needs to be separated out from the efficiency variance
The efficiency variance will then only record the active working hours
Idle time is always adverse
What are the three variable Overhead variances and their definitions?
Total variance
Difference between the actual and standard direct variable overhead costs of the output produced
Variable overhead expenditure variance
actual overhead cost incurred – (actual hours worked x standard variable production overhead absorption rate per hour)
Variable overhead efficiency variance
(actual hours worked x standard variable production overhead absorption rate per hour) – (actual production in standard hours x standard variable overhead absorption rate per hour)
How do you calculate the variable overhead variances?
Variable overhead expenditure overhead £
Actual hours @ standard price
Actual cost
Variable overhead efficiency variance hours
Actual units should have used x ? hours
Actual units did use
X standard hourly rate £
What are the three sales variances?
Sales Price Variance
(Actual sales volume x standard selling price per unit) – actual sales revenue
Sales volume variance Budgeted sales units – actual sales units Then value at: x standard gross profit per unit x standard contribution per unit x standard revenue per unit
What are the three fixed overhead variances?
Fixed Overhead total Variance
Overheads absorbed x
Actual overhead incurred y
Fixed production overhead total variance x–y
Fixed Overhead expenditure variance
Budgeted fixed overheads x
Actual fixed overheads y
Fixed overhead expenditure variance x–y
How do you calculate fixed production overhead volume variances?
Fixed production overhead volume variance
Actual output x
Budgeted output y
Volume variance in units x-y
X standard fixed overhead rate per unit £z
Fixed production overhead volume variance £z x (x-y)
How do you present the operating statement?
Absorption costing: £ Budgeted gross profit x Sales volume profit variance x Sales price variance x x Cost variances x Actual gross profit x
Include fixed overhead expenditure and fixed overhead volume variances in cost variances
How do you present the operating statement for marginal costing?
£ Budgeted contribution x Sales volume contribution variance x Sales price Variance x x Cost variances x Actual contribution x Budgeted overheads x Fixed overhead expenditure variance x Actual profit x
What could the causes for material price variances be?
Using a different supplier
Bulk buying – extra discounts
Unexpected increase in prices
Change in material quality
What could the causes for material usage variances be?
More or less scrap or wastage Change in material quality Change in quality control More efficient work procedures Change in material mix
What could the causes for labour rate variances be?
Increase in basic wages
Payment of bonuses
Using labour less or more experienced
Change in mix of labour force
What could the causes for labour efficiency variances be?
Using labour less or more experienced Change in mix and therefore efficiency Improved working methods Industrial action Poor supervision
