Overhead Costs Formula
Overhead costs are calculated by summing all indirect business expenses. The Overhead Rate is then determined by dividing the total overhead by a specific allocation base, typically direct labor cost.
Total Monthly Overhead (TMO):
TMO = Monthly Rent + Utilities + Admin Salaries + Other Fixed Costs
Overhead Rate (%):
Overhead Rate = (TMO / Total Direct Labor Cost) × 100
Formula adapted from: Investopedia – Overhead Definition, QuickBooks – Overhead Rate Calculation
Variables Explained
The following variables are used in the calculator to determine your total monthly overhead and the corresponding rate:
- Monthly Fixed Rent/Mortgage ($): The regular, predictable cost of your physical business space.
- Monthly Utilities/Other Fixed Costs ($): Stable, non-production related costs like insurance, software subscriptions, and utility bills.
- Monthly Admin Salaries/Indirect Labor ($): Compensation for non-production personnel (e.g., HR, accounting, administrative staff).
- Monthly Total Direct Labor Cost ($): The cost of labor directly involved in producing your goods or services. This acts as the allocation base for the Overhead Rate.

What are Overhead Costs?
Overhead costs are the ongoing, indirect expenses required to run a business but which cannot be directly traced to any single product or service unit. They are crucial for budgeting, setting prices, and determining how much revenue a company needs to generate to be profitable. Overhead costs are typically categorized as fixed (like rent) or variable (like shipping or office supplies), although this calculator focuses on the primary fixed monthly costs.
Properly allocating and controlling overhead is paramount for financial health. If a company underestimates its overhead, it may set product prices too low, leading to losses. Conversely, if overhead is inflated, the company may overprice its products, losing competitive edge. Understanding the **Overhead Rate** helps businesses assign these indirect costs to specific jobs or departments for accurate cost accounting.
How to Calculate Overhead Costs (Example)
Follow these steps to calculate the Total Monthly Overhead (TMO) and Overhead Rate for a sample business:
- Sum Fixed Costs: Gather all monthly fixed overhead expenses. E.g., Rent ($4,000) + Utilities ($1,500) + Admin Salaries ($8,000) = $13,500 TMO.
- Identify the Allocation Base: Determine the base for allocation. Let’s use Total Direct Labor Cost, which is $20,000 for the month.
- Calculate the Overhead Rate: Divide TMO by the allocation base and multiply by 100. $13,500 / $20,000 = 0.675.
- Determine the Percentage: The final Overhead Rate is 67.5%. This means for every dollar spent on direct labor, $0.675 is spent on overhead.
Frequently Asked Questions (FAQ)
What is the difference between overhead and operating expenses?
Overhead is a component of operating expenses. Operating expenses include all non-production costs (both direct and indirect). Overhead specifically refers to the indirect costs necessary to keep the business running, like rent and administrative salaries. Selling, General, and Administrative (SG&A) often encompass the bulk of overhead.
Is the Overhead Rate always calculated based on labor cost?
No. While direct labor cost is a common allocation base, the Overhead Rate can also be calculated using machine hours, direct material cost, or total sales, depending on which base provides the most accurate and logical distribution of costs for the specific business model.
How do I reduce overhead costs?
Reducing overhead often involves reviewing fixed costs. Strategies include negotiating lower rent, migrating to a smaller office space, optimizing utility usage, transitioning to cheaper software subscriptions, or outsourcing non-core administrative functions.
What is a ‘good’ Overhead Rate?
There is no universally ‘good’ rate, as it varies significantly by industry (e.g., service vs. manufacturing). However, a lower rate is generally preferable as it indicates that a smaller percentage of revenue is absorbed by non-production costs, suggesting higher efficiency and profitability potential.
