To calculate overhead costs, start by adding up all your indirect expenses such as rent, utilities, administrative salaries, and marketing to find your total overhead. Then, divide this total by an appropriate allocation base like total sales, direct labor costs, or labor hours. This gives you the overhead rate, which you can use to accurately assign overhead costs to your products or services.
Overhead Rate Formula: Overhead Rate = Total Indirect Costs / Allocation Base
This rate helps you understand how much overhead gets allocated per unit of the chosen base, simplifying pricing and cost control.
For ecommerce businesses, properly calculating overhead costs can mean the difference between sustainable growth and unexpected financial strain.
This comprehensive guide will walk you through everything you need to know about overhead cost calculation, from basic definitions to advanced formulas, real-world examples, and proven strategies to reduce these expenses while maintaining operational efficiency.
What Is Overhead Cost?
Definition of Overhead
Overhead costs are the ongoing business expenses that cannot be directly attributed to creating specific products or services. Unlike direct costs that fluctuate with production volume, overhead expenses remain relatively constant regardless of how much you produce or sell. These indirect costs are essential for keeping your business operational but don’t directly contribute to the creation of your products.

Understanding overhead costs is vital for accurate business analysis because they significantly impact your profitability, pricing strategies, and break-even calculations. Many business owners underestimate their true overhead expenses, leading to pricing products too low and eroding profit margins.
Overhead vs Direct Costs
The distinction between overhead and direct costs is fundamental to proper cost management:
Direct Costs | Overhead Costs |
Materials and supplies used in production | Rent and utilities |
Direct labor costs for manufacturing | Administrative salaries |
Shipping costs per order | Insurance premiums |
Product-specific packaging | Marketing and advertising |
Commission per sale | Software subscriptions |
Raw materials | Legal and accounting fees |
Many business owners initially struggle with this classification, especially when it comes to employee wages or technology costs. The key is determining whether the expense directly relates to producing a specific unit of product or service. Misclassifying these costs can lead to inaccurate pricing, poor financial decisions, and reduced profitability.
Types of Overhead Costs
Understanding different types of overhead costs helps you better manage and predict your business expenses. Each type behaves differently as your business grows or contracts.
Overview of Corporate Cost Types
Cost Type | Meaning | Examples |
Fixed Costs | Costs that stay the same regardless of production output or activity. | Rent, insurance, salaries, depreciation |
Variable Costs | Costs that rise or fall in line with production levels. | Raw materials, direct labor, sales commissions |
Semi-Variable Costs | Costs that include both fixed and variable elements. | Utilities, maintenance, cell phone bills |
Direct Costs | Costs that can be clearly linked to a particular product or project. | Direct materials, direct labor, project-specific costs |
Indirect Costs | Costs that cannot be directly assigned to a single product or project. | Factory overhead, admin salaries, building upkeep |
Product Costs | Costs directly related to producing goods. | Materials, labor, manufacturing overhead |
Period Costs | Costs tied to time periods rather than production. | Selling expenses, administrative costs, marketing expenses |
Fixed Overhead
Fixed overhead costs remain constant regardless of your business activity level. These expenses provide stability in financial planning but can be challenging during slow periods:
- Rent or mortgage payments – Office, warehouse, or retail space costs
- Insurance premiums – Business liability, property, and workers’ compensation
- Fixed salaries – Administrative staff, managers, and core team members
- Loan payments – Equipment financing and business loans
- Annual licenses and permits – Business registration and regulatory fees
- Base utility charges – Minimum monthly fees for phone, internet, and utilities
Variable Overhead
Variable overhead expenses fluctuate with your business activity, increasing during busy periods and decreasing during slower times:
- Shipping and delivery costs
- Sales commissions and bonuses
- Office supplies and materials
- Travel and entertainment expenses
- Temporary staffing costs
- Processing fees for payments
- Marketing campaign costs
Semi-Variable Overhead
Semi-variable overhead costs combine fixed and variable components, creating a base cost that increases with activity. These expenses often have minimum charges plus usage-based fees:
- Utilities – Base connection fees plus usage charges
- Phone and internet – Monthly plans with overage charges
- Employee benefits – Base coverage plus performance bonuses
- Software subscriptions – Tiered pricing based on users or features
- Equipment leases – Fixed monthly payments with maintenance costs
Direct Costs
Direct costs are expenses that can be specifically traced to producing a particular product or service. They include costs like raw materials and wages paid to workers directly involved in manufacturing. These costs vary directly with the level of production.
- Direct materials – wood used in furniture, fabric used in clothing
- Direct labor – wages paid to workers who assemble products
- Project-specific expenses – special tools or equipment needed only for one project
Indirect Costs
Indirect costs are expenses that support production but cannot be directly linked to a specific product. Examples include factory rent, utilities, and salaries of supervisors. These costs are typically fixed or semi-fixed and are also known as overhead.
- Factory overhead – electricity, equipment depreciation
- Administrative salaries – office staff wages not linked to production
- Building maintenance – cleaning, repairs, and general upkeep
Product Costs
Product costs encompass all expenses incurred to create a product, including direct materials, direct labor, and manufacturing overhead. These costs are inventoried on the balance sheet and expensed as the cost of goods sold only when the product is sold.
- Materials – raw inputs like steel, plastic, or chemicals
- Labor – workers directly involved in production
- Manufacturing overhead – utilities, machine operation costs
Period Costs
Period costs are all other costs not tied to production and are expensed in the period incurred. They include selling, general, and administrative expenses such as marketing, office rent, and executive salaries.
- Selling expenses – advertising, sales commissions
- Administrative costs – office supplies, accounting fees
- Marketing expenses – promotional campaigns, digital ads
Other Types Of Overhead Cost
Administrative vs Production Overhead
For ecommerce and retail businesses, it’s helpful to categorize overhead into administrative and production-related expenses:
Administrative Overhead | Production Overhead |
Office rent and utilities | Warehouse space |
Administrative salaries | Equipment maintenance |
Marketing and advertising | Quality control costs |
Legal and accounting fees | Inventory storage |
Office software and supplies | Packaging materials (bulk) |
Business insurance | Safety and compliance costs |
Why Overhead Cost Calculation Matters for Your Business
Profitability Impact
High overhead costs directly diminish your net profits by reducing the amount of revenue that flows to your bottom line. Every dollar spent on overhead requires additional sales to maintain the same profit level. Businesses with efficiently managed overhead costs enjoy competitive advantages through better pricing flexibility, higher profit margins, and increased resilience during economic downturns. Understanding your true overhead burden helps you make informed decisions about growth investments, staffing levels, and operational changes.
Pricing Strategy
Accurate overhead calculation is essential for sustainable pricing strategies. If you don’t account for all overhead costs when setting prices, you risk selling products below their true cost, eroding profitability over time.
For example, if your monthly overhead is $8,000 and you sell 400 units per month, each unit must absorb $20 in overhead costs ($8,000 ÷ 400 = $20). If your direct costs are $30 per unit and you want a 40% profit margin, your minimum selling price should be ($30 + $20) × 1.4 = $70 per unit.
Breakeven Analysis
Breakeven analysis determines how many units you must sell to cover all costs, and overhead calculation accuracy directly impacts this critical metric.
Breakeven Point Formula: Breakeven Units = Total Fixed Costs ÷ (Selling Price per Unit – Variable Cost per Unit)
If your fixed overhead is $10,000 monthly, selling price is $50, and variable costs are $25, you need to sell 400 units monthly to break even ($10,000 ÷ ($50 – $25) = 400 units). Understanding this calculation helps you set realistic sales targets and identify when your business becomes profitable.
How To Calculate Overhead Cost Step-by-Step
Identify All Overhead Expenses
Follow these steps to comprehensively identify your overhead expenses:
- Review your chart of accounts – Go through each expense category systematically
- Categorize fixed vs variable costs – Separate expenses that remain constant from those that fluctuate
- Include indirect labor – Count administrative and support staff salaries
- Account for facility costs – Include rent, utilities, maintenance, and insurance
- List professional services – Add legal, accounting, and consulting fees
- Include technology costs – Software subscriptions, hardware leasing, and IT support
- Consider depreciation – Include equipment and asset depreciation
- Add miscellaneous expenses – Office supplies, travel, and other indirect costs

Calculate Total Overhead for a Period
Use this formula to calculate your total overhead for any period:
Total Overhead = Fixed Overhead + Variable Overhead + Semi-Variable Overhead
For monthly calculations:
- Annual expenses ÷ 12 = Monthly overhead
- Weekly expenses × 4.33 = Monthly overhead
- Daily expenses × 30.44 = Monthly overhead
Example Calculation (with sample data)
Here’s a practical example for a Shopify store’s monthly overhead calculation:
Overhead Category | Monthly Cost |
Office rent | $2,000 |
Utilities | $350 |
Insurance | $400 |
Shopify subscription | $79 |
Administrative salary | $4,000 |
Marketing tools | $200 |
Accounting software | $50 |
Internet and phone | $120 |
Professional services | $500 |
Office supplies | $150 |
Total Monthly Overhead | $7,849 |
This calculation shows the business has $7,849 in monthly overhead costs that must be covered regardless of sales volume.
Overhead Rate Formula
The overhead rate helps you understand overhead as a percentage of sales or other business metrics:
Overhead Rate = (Total Overhead ÷ Total Sales) × 100%
Using our example: If monthly sales are $25,000 and overhead is $7,849:
Overhead Rate = ($7,849 ÷ $25,000) × 100% = 31.4%
This means overhead represents 31.4% of total sales, which is within the typical range for small businesses (25-35%).
Alternative allocation bases:
- Overhead per labor hour = Total Overhead ÷ Total Labor Hours
- Overhead per machine hour = Total Overhead ÷ Total Machine Hours
- Overhead per square foot = Total Overhead ÷ Total Facility Square Footage
Per Unit/Per Order Calculation
Calculating overhead per unit or order helps with pricing decisions:
Overhead per Unit = Total Overhead ÷ Number of Units Produced
Overhead per Order = Total Overhead ÷ Number of Orders
Shopify Store Example:
Monthly overhead: $7,849
Monthly orders: 320
Overhead per order = $7,849 ÷ 320 = $24.53
This means each order must contribute at least $24.53 toward overhead costs. Combined with direct costs and desired profit margin, this helps establish minimum pricing thresholds.

Strategies for Managing Overhead Costs
Overhead costs can significantly impact a company’s profitability, so they must be carefully controlled without compromising quality or sales. The key to successful business management is making smart spending decisions that balance cost savings with operational effectiveness.
Regularly reviewing and analyzing overhead expenses is essential to optimizing efficiency. Managers should stay alert to rising costs and quickly assess the effects of any cost-cutting measures to avoid unintended harm.
Some practical and relatively low-risk ways to reduce overhead include:
- Negotiating Better Rates: Leverage long-term relationships with suppliers and service providers to secure improved pricing or terms. If viable, explore competitive alternatives to ensure you’re getting the best deal.
- Outsourcing or Insourcing: Depending on the business needs, consider outsourcing key functions such as IT support, payroll, accounting, or legal services to external experts, or alternatively, bringing these roles in-house if it proves more cost-effective.
- Streamlining Operations: Conduct thorough analyses to identify non-essential tasks and redundant expenses. Simplifying processes and eliminating unnecessary steps can lead to significant savings without impacting sales.
- Embracing Remote Work: Allowing employees to work from home can reduce costs related to office space, utilities, and equipment. Staff benefit from saved commuting time, while businesses can downsize their physical footprint.
- Leveraging Technology: Use automation tools and technology to handle routine tasks efficiently. While simple, repetitive jobs can be automated, complex decision-making typically still requires human oversight.
By implementing these strategies, businesses can keep overhead costs in check, improving their financial health and competitiveness.

Overhead Costs FAQs
Overheads – also called overhead costs or indirect costs – are expenses that support a company’s operations but cannot be directly assigned to a specific product, service, or project. They apply to the business as a whole and are essential for keeping day-to-day operations running.
For ecommerce businesses, an overhead rate between 20-30% of total sales is considered good, with rates under 25% being excellent. This range allows for adequate operational support while maintaining healthy profit margins. Newer businesses often start with higher rates (30-35%) as they build efficiency and scale.
Overhead costs are recurring business expenses that are not directly tied to producing a product or delivering a service. They include essential operating costs such as rent, utilities, insurance, employee salaries, internet, office supplies, accounting, and legal fees.
It means for every $1 of direct costs, the business spends an additional $0.30 on overhead expenses.
Add up all indirect expenses (like rent, utilities, admin salaries), then divide by a base such as direct labor costs, machine hours, or sales to find the rate.
Review overhead costs monthly for tracking purposes and quarterly for strategic analysis. Monthly reviews help identify unusual expenses and ensure budget compliance, while quarterly reviews allow for deeper analysis of trends and cost-reduction opportunities. Annual reviews should comprehensively evaluate all overhead categories and set targets for the coming year.
