Overview of Standard Costing
Overview of Standard Costing
Standard costing is a management accounting control technique that sets predetermined (budgeted) costs and revenues, then compares these against actual results to identify variances.
Standard cost — the expected cost of producing one unit, set in advance, covering materials, labour and overheads.
Variance analysis — the process of identifying and investigating differences between standard and actual performance.
How a standard costing system operates
- Set standards (budgeted information) for materials, labour and sales
- Compare standard costs and sales with actual costs and sales
- Identify the variances (differences between standard and actual)
- Investigate the reasons / causes for the variances
- Take corrective action (including potentially resetting standards)
Favourable vs Adverse variances
A variance is either favourable (F) or adverse (A):
- Favourable — actual result is better than standard (lower cost or higher revenue than expected)
- Adverse — actual result is worse than standard (higher cost or lower revenue than expected)
Causes of favourable variances:
- Actual sales higher than standard (higher volume and/or higher unit price)
- Actual material cost lower than standard (lower quantity used and/or lower unit cost)
- Actual labour cost lower than standard (fewer hours used and/or lower hourly rate)
Causes of adverse variances:
- Actual sales lower than standard (lower volume and/or lower unit price)
- Actual material cost higher than standard (higher quantity used and/or higher unit cost)
- Actual labour cost higher than standard (more hours used and/or higher hourly rate)
Labelling variances
- By deducting actual from standard, a positive figure is favourable and a negative figure is adverse
- Each variance must be labelled with a £ sign and F or A
- Adverse variances do not need to be shown in brackets (though brackets are acceptable)
