What it means
When you run a business, you have two main types of expenses: direct costs and overhead costs. Direct costs change based on how much you produce.
For instance, if you bake cakes, the flour and sugar are direct costs. Overhead costs, on the other hand, stay largely the same whether you bake one cake or one thousand cakes.
They keep the lights on and the doors open, providing the necessary infrastructure for your team to do their work. Understanding your overhead is crucial for pricing and survival.
If your overhead is too high, it eats up all your profits, leaving you with nothing even if your sales look impressive on paper. Managers track overhead carefully to spot waste, trim unnecessary subscriptions, and ensure the business maintains enough cash reserve to get through quiet months.
In everyday practice, businesses separate overhead into fixed and variable categories. Fixed overhead includes things like annual property leases that never change month to month.
Variable overhead includes items like electricity bills or office supplies that fluctuate slightly based on activity levels, but still do not directly connect to creating your core product. Controlling these expenses is often the difference between a thriving enterprise and a struggling one.
While direct costs scale nicely with revenue, high overhead can quietly drain your bank account. Reviewing these expenses regularly helps non-finance managers make smart choices about office space, software licenses, and support staff.
In practice
Real-world examples.
Example
Sarah runs a boutique coffee shop. Her monthly rent of 2,000 pounds, commercial insurance of 150 pounds, and accountant fees of 200 pounds are all overhead costs, payable whether she sells one coffee or ten thousand.
Example
A regional plumbing firm with five vans must pay 1,200 pounds monthly for fleet insurance, 800 pounds for office rent, and 300 pounds for booking software. These overhead costs continue even during a quiet week with few jobs.
Example
A software development agency employs twenty programmers. Their office lease, legal compliance fees, and human resources software subscriptions count as overhead because they support the business as a whole rather than one specific client project.
Think of it
“Think of overhead costs like the fuel and maintenance required to run a tour bus. Even if the bus has zero passengers on board today, you still need to pay for insurance, garage space, and regular servicing just to keep the vehicle ready for the road.
Formula
Calculation
Total Overhead Cost = Fixed Overhead + Variable Overhead
For example, if your graphic design studio has a monthly office rent of 1,500 pounds, utility bills of 200 pounds, insurance of 100 pounds, and software subscriptions of 300 pounds:
Total Overhead = 1,500 + 200 + 100 + 300 = 2,100 pounds per month.
To find your overhead rate per project, divide total overhead by your total direct labour hours. If your team works 700 hours a month, your overhead rate is 2,100 divided by 700, which equals 3 pounds per labour hour.Case study
Seen in the real world.
GreenLeaf Landscaping, a growing garden maintenance firm, experienced a surge in customer contracts during the summer. The owner, Mark, celebrated the rising revenue by leasing a larger, more prestigious office and hiring a full-time receptionist, which pushed monthly overhead from 3,000 pounds to 6,500 pounds. When autumn arrived, regular garden maintenance contracts dropped by half. Because Mark had locked into a long-term commercial lease and salary commitment, his monthly overhead remained at 6,500 pounds despite a significant drop in incoming cash. GreenLeaf quickly ran into a cash flow crisis, struggling to pay fuel and equipment suppliers. To survive, Mark had to sublet half the office space and negotiate a temporary part-time schedule for administrative support. The experience taught him that overhead costs must be scaled carefully alongside predictable, long-term revenue rather than short-term sales spikes.
Watch out
Common mistakes.
- Treating direct production costs as overhead, which distorts product pricing and profit margins.
- Ignoring small recurring software subscriptions that quietly add up to a massive annual overhead total.
- Locking into rigid, long-term overhead commitments based on a temporary surge in seasonal sales.
Questions
People also ask.
Are staff salaries always considered overhead?
Not always. Salaries for administrative, human resources, and executive staff are overhead. However, the wages of factory workers or service providers who directly make the product are classified as direct labour costs.
How do I reduce my overhead without hurting the business?
Start by auditing all recurring software subscriptions, negotiating better rates with utility and service providers, and considering remote or hybrid working models to downsize expensive physical office space.
Why is tracking overhead important for setting prices?
If you only price your products to cover direct material and labour costs, you will not generate enough money to pay your rent and utilities, leading to a net loss overall.
