How to Calculate Variable Cost: The Formula
Total Variable Cost (TVC) = Variable Cost per Unit (V) × Number of Units Produced (Q)
Formula Sources: Investopedia, Corporate Finance InstituteVariables Explained
- Total Variable Cost (TVC): The sum of all variable costs for a specific period or production run.
- Variable Cost per Unit (V): The monetary cost of a single unit of production that varies with output (e.g., raw materials, direct labor).
- Number of Units Produced (Q): The quantity of goods or services manufactured or delivered.
What is Variable Cost?
Variable costs are expenses that fluctuate in direct proportion to changes in production volume or business activity. Unlike fixed costs (which remain constant regardless of output, such as rent), variable costs increase when production increases and decrease when production falls. They are crucial for calculating profitability metrics like Break-Even Point and Contribution Margin.
Understanding variable costs allows management to set optimal pricing strategies, determine inventory levels, and perform accurate cost-volume-profit (CVP) analysis. The most common examples of variable costs are raw materials, packaging, sales commissions, and utilities directly tied to production usage.

How to Calculate Variable Cost (Example)
Imagine a small toy company, “ToyCo,” wants to calculate its Total Variable Cost for producing 5,000 action figures.
- Determine Variable Cost per Unit (V): ToyCo finds that the plastic, paint, and packaging for one action figure totals $3.50. So, V = $3.50.
- Determine Number of Units Produced (Q): The production run is 5,000 figures. So, Q = 5,000.
- Apply the Formula: Total Variable Cost (TVC) = V × Q.
- Calculate the Result: TVC = $3.50 × 5,000 = $17,500.
- Conclusion: The Total Variable Cost for producing 5,000 action figures is $17,500.
Frequently Asked Questions (FAQ)
Is direct labor a variable cost?
Yes, direct labor is typically considered a variable cost, especially in manufacturing, because the total cost of labor increases with the number of hours required to produce more units. However, salaried employees (like supervisors) are usually fixed costs.
What is the difference between variable cost and marginal cost?
Variable cost is the total cost that changes with volume. Marginal cost is the additional cost incurred to produce one more unit. While closely related (marginal cost is often the variable cost per unit), marginal cost specifically looks at the change from one level of output to the next.
How do I find variable cost in an income statement?
Variable costs are often included within the Cost of Goods Sold (COGS). To find the true variable cost, you must separate the variable components of COGS (like materials) from fixed components (like depreciation of factory equipment).
Why is variable cost important for the Break-Even Point?
The variable cost per unit is essential for calculating the contribution margin (Selling Price – Variable Cost per Unit). The Break-Even Point is calculated by dividing Total Fixed Costs by the Contribution Margin, meaning a lower variable cost leads to a lower break-even point.
