What it means
Overhead is the collection of costs you pay just to keep your business open, whether you sell a lot or very little on any given day. Think of rent, utilities, insurance and the salaries of administrative staff who support everyone else.
Overhead differs from direct costs, which rise and fall with each unit you make, such as the flour in a loaf of bread. Because overhead supports the whole business at once, it is hard to link to any single product or customer.
Managers care about overhead because it decides how much you must earn before you make a real profit. A business with $20,000 of monthly overhead must generate $20,000 of gross profit (sales minus the direct cost of those sales) just to break even.
Everything above that is profit, and everything below it is a loss. Overhead is often split into fixed items, such as rent, and variable items, such as utilities, which move a little with activity.
Many managers track it as a percentage of revenue and review it each quarter to spot subscriptions nobody uses or space nobody needs. Overhead also feeds into pricing.
Because it cannot be traced to one product, businesses spread it across their products using a rate or an allocation method, so that every price includes a fair share of the running costs. A business that ignores this step can look busy and still lose money.
Think of overhead like the cost of owning a car: you pay for insurance, servicing and parking even on weeks when you hardly drive it.
In practice
Real-world examples
Example 1
An entrepreneur runs a small online retail store with monthly website hosting of $50, internet of $80 and an e-commerce platform subscription of $79. Together these overhead costs come to $209 a month and are due however many orders arrive. On a slow month with only a handful of sales, they still have to be paid in full.
Example 2
A small manufacturing company pays $4,000 a month for factory rent, $3,500 for an office manager and $1,000 for utilities. That is $8,500 of overhead that must be covered before any product makes a profit. If the firm sells fewer units next month, the bill stays exactly the same.
Example 3
A dental practice pays $4,200 for its clinic lease, $3,000 for a receptionist and $800 for professional insurance each month. These $8,000 of overhead costs support every patient visit, but none of them can be assigned to a single treatment. The practice must therefore build a share of them into the fee for every appointment.
Think of it
Think of overhead like the maintenance costs of owning a car: you need to pay for insurance, regular servicing, and parking even when the car is not being driven.
Formula
Calculation
Overhead Ratio = (Total Overhead / Total Revenue) x 100
For example, a studio has monthly overhead of $12,000, made up of $5,000 rent, $5,000 administrative salaries and $2,000 of insurance, utilities and software. With revenue of $60,000, the overhead ratio is 12,000 / 60,000 = 20%.
If a quiet month brings revenue of only $40,000, overhead is still $12,000, so the ratio rises to 12,000 / 40,000 = 30%. The business has not spent more, but each dollar of sales now has to carry a heavier share of the fixed bills.Case study
Seen in the real world
This is a fictional, illustrative scenario. Brightside Print Studio, an invented small printing business, had monthly revenue of $45,000, direct costs of $27,000 and overhead of $9,000, leaving a profit of $9,000. The owner felt comfortable with these numbers and rarely looked at the overhead line. In a slow season, revenue fell by a third to $30,000 and direct costs fell to $18,000, leaving gross profit of $12,000. Overhead stayed at $9,000, so profit dropped to $3,000.
Revenue had fallen by one third, yet profit had fallen by two thirds, because the fixed bills did not shrink with sales. The owner reviewed every recurring bill, cancelled $1,500 a month of unused software and equipment rental, and renegotiated part of the lease. Overhead now sits at $7,500, so the studio needs less revenue to break even and can cope with quiet months more comfortably. The owner also adds a one-line overhead check to the monthly management report, so the figure is never ignored again.
Watch out
Common mistakes
- Treating overhead as something you cannot control, when subscriptions, space and insurance can all be reviewed and renegotiated.
- Counting direct costs, such as materials used in a product, as overhead, which makes products look more profitable than they are.
- Taking on new fixed overhead after a good month without checking it is affordable in a bad one.
Questions
People also ask
Is overhead the same as operating expenses?
They overlap heavily, but operating expenses is the broader accounting term for the costs of running the business, while overhead usually means the support costs that cannot be traced to a single product.
Do salaries count as overhead?
Only when they support the whole business, such as administration, finance or management. The wages of staff who directly make the product or deliver the service are direct labour.
What is a healthy level of overhead?
There is no single answer because it varies widely by industry, but the key test is whether your gross profit comfortably covers it with room to spare.
