Calculating variable costs in a stock company, or any business, involves understanding which costs change with the level of production or sales activity. Variable costs are those that vary directly with the volume of production or sales. Here’s a step-by-step guide to calculating variable costs:
1. Identify Variable Costs
Variable costs are those that change with production or sales levels. Common examples include:
- Raw Materials: Costs of materials used in production.
- Direct Labor: Wages of employees directly involved in production.
- Sales Commissions: Fees paid based on sales volume.
- Utilities: Costs like electricity that increase with higher production levels.
2. Gather Data
Collect data on your costs over different levels of production or sales. This data should include:
- Total Costs: Record total variable costs in INR associated with different levels of output.
- Production Levels: Note the corresponding production or sales volumes for each cost figure.
3. Calculate Variable Cost Per Unit
To find the variable cost per unit in INR, use the following formula:
Variable Cost Per Unit = Total Variable Costs (INR) / Total Units Produced
Where:
- Total Variable Costs (INR) are the costs that vary with production (e.g., raw materials, direct labor).
- Total Units Produced is the number of units produced during the cost period.
Example: If the total variable costs for producing 1,000 units are ₹50,000, then:
Variable Cost Per Unit = 50000 / 1000 = 50
So, the variable cost per unit is ₹50.
4. Determine Total Variable Costs
To find total variable costs for any production level in INR, use the following formula:
Total Variable Costs (INR) = Variable Cost Per Unit × Number of Units Produced
Example: If the variable cost per unit is ₹50 and you produce 2,000 units, then:
Total Variable Costs (INR) = 50 × 2000 = 100000
So, the total variable costs are ₹100,000.
5. Analyze the Cost Behavior
Analyze how variable costs behave as production levels change. This involves:
- Creating a Cost-Volume-Profit (CVP) Analysis: A CVP analysis helps understand the relationship between costs, sales volume, and profit in INR.
- Plotting Costs: Plot variable costs against production levels to visualize the direct correlation.
6. Adjust for Business Changes
If there are significant changes in business operations, such as a new production process or changes in supplier prices, adjust your calculations accordingly.
7. Integrate into Financial Planning
Incorporate variable cost calculations into budgeting and forecasting to better predict financial outcomes based on different levels of production or sales.
Example Scenario
Company XYZ produces widgets. Their data for different production levels is as follows:
- At 1,000 widgets: Total Variable Costs = ₹70,000
- At 2,000 widgets: Total Variable Costs = ₹1,40,000
From this data, the variable cost per unit is:
Variable Cost Per Unit = 70000 / 1000=70
And if the company plans to produce 3,000 widgets:
Total Variable Costs (INR) = 70 × 3000 = 210000
So, the total variable costs for producing 3,000 widgets would be ₹2,10,000.
By following these steps with INR, you can accurately determine the variable costs for any level of production or sales, which helps in making informed financial decisions.
