Overview of Standard Costing
Standard costing is a system used to assign predetermined costs to products or services. These standards are based on historical data, industry benchmarks, or management expectations and represent what the costs should be under normal operating conditions. When actual costs are incurred, they are compared to these standards, and the differences are analyzed through variance analysis.
The primary objectives of standard costing include:
- Providing a basis for budgeting and cost control.
- Identifying inefficiencies in the production process.
- Assisting in performance evaluation and managerial decision-making.
- Facilitating the planning of future operations by establishing cost expectations.
The benefits of standard costing extend to multiple aspects of a business. It simplifies cost accounting by standardizing cost measurement and provides early warning signals about variances that require attention. Furthermore, it enables managers to compare performance across different periods and departments, thereby fostering a culture of continuous improvement.
Standard costing emerged during the early 20th century as production processes became more complex. As companies grew larger and production methods became more mechanized, management needed a reliable method to control costs and measure performance. Over time, standard costing evolved to include direct costs as well as variable and fixed overheads, ensuring a comprehensive view of production efficiency.
Components of Standard Costing
Standard costing involves setting standards for the three primary components of production cost: Direct Materials, Direct Labor, and Overhead.
1. Direct Materials
Direct materials refer to the raw inputs that become an integral part of the finished product. In standard costing, a standard cost is determined for the quantity of materials expected to be used and the price per unit. Variances in direct materials can be split into:
- Material Price Variance (MPV): The difference between the actual cost per unit and the standard cost, multiplied by the actual quantity purchased.
- Material Usage Variance (MUV): The difference between the actual quantity used and the standard quantity allowed, multiplied by the standard price.
2. Direct Labor
Direct labor represents the cost of labor directly involved in the production process. The standard costing method involves setting a standard labor rate and a standard time required for production. The variances related to labor include:
- Labor Rate Variance (LRV): The difference between the actual hourly rate and the standard hourly rate, multiplied by the actual hours worked.
- Labor Efficiency Variance (LEV): The difference between the actual labor hours used and the standard hours allowed, multiplied by the standard rate.
3. Overhead
Overhead costs are indirect production costs that cannot be directly traced to a single product, such as utilities, rent, and depreciation. Overhead variances are divided into:
- Variable Overhead Variances:
- Spending Variance: The difference between the actual variable overhead rate and the standard rate, multiplied by the actual hours worked.
- Efficiency Variance: The difference between the actual hours worked and the standard hours allowed, multiplied by the standard variable overhead rate.
- Fixed Overhead Variances:
- Budget Variance: The difference between the budgeted fixed overhead and the actual fixed overhead incurred.
- Volume Variance: The difference between the applied fixed overhead (based on production volume) and the budgeted fixed overhead.
Each of these variances provides valuable insight into different aspects of the production process, enabling managers to pinpoint areas where performance deviates from expectations.

Step-by-Step Variance Calculations
ABC Manufacturing’s management performs variance analysis to determine where actual costs deviated from standards. Below are the calculations:
1. Direct Materials Variances
Material Price Variance (MPV): Calculated as:
MPV = (Actual Price – Standard Price) x Actual Quantity Purchased
= (INR 385 - INR 350) x (1,100 units x 3)
= INR 35 x 3,300
= INR 115,500 Unfavorable
Material Usage Variance (MUV): Calculated as:
MUV = (Actual Quantity Used - Standard Quantity Allowed) x Standard Price
= (3.2 - 3.0) x INR 350 x 1,100
= 0.2 x INR 350 x 1,100
= INR 77,000 Unfavorable
2. Direct Labor Variances
Labor Rate Variance (LRV): Calculated as:
LRV = (Actual Rate - Standard Rate) x Actual Hours
= (INR 1,470 - INR 1,400) x (0.55 x 1,100)
= INR 70 x 605
= INR 42,350 Unfavorable
Labor Efficiency Variance (LEV): Calculated as:
LEV = (Actual Hours - Standard Hours Allowed) x Standard Rate
= (0.55 - 0.50) x INR 1,400 x 1,100
= 0.05 x INR 1,400 x 1,100
= INR 77,000 Unfavorable
3. Overhead Variances
Variable Overhead
Variable Overhead Spending Variance: Calculated as:
Variable OH Spending Variance = (Actual Rate - Standard Rate) x Actual Hours
= (INR 147 - INR 140) x (0.55 x 1,100)
= INR 7 x 605
= INR 4,235 Unfavorable
Variable Overhead Efficiency Variance: Calculated as:
Variable OH Efficiency Variance = (Actual Hours - Standard Hours Allowed) x Standard Rate
= (0.55 - 0.50) x INR 140 x 1,100
= 0.05 x INR 140 x 1,100
= INR 7,700 Unfavorable
Fixed Overhead
Fixed Overhead Budget Variance: Calculated as:
Fixed OH Budget Variance = Budgeted Fixed OH - Actual Fixed OH
= INR 700,000 - INR 665,000
= INR 35,000 Favorable
Fixed Overhead Volume Variance: First, calculate Applied Fixed OH:
Applied Fixed OH = (Actual Production Units / Standard Production Units) x Budgeted Fixed OH
= (1,100 / 1,000) x INR 700,000
= INR 770,000
Fixed OH Volume Variance = Applied Fixed OH - Budgeted Fixed OH
= INR 770,000 - INR 700,000
= INR 70,000 Unfavorable
The above calculations indicate the areas where ABC Manufacturing deviated from its standards, highlighting both favorable and unfavorable variances.
