What it means
Imagine you run a bakery. The flour, sugar, and baker's wages are direct costs to bake the bread.
SG and A covers everything else needed to keep the doors open and sell that bread. This includes advertising, the salary of the accountant, utility bills for the shop, and software subscriptions.
Selling expenses cover activities required to market, promote, and sell products. General and administrative expenses cover the overhead costs of running the business as a whole.
While these costs do not directly create the product, they are vital for business survival and growth. For non-finance managers, keeping an eye on SG and A is essential because these costs can easily spiral out of control if left unmanaged.
Unlike manufacturing costs that rise naturally when you sell more products, SG and A often stays fixed. Controlling these overheads directly protects your profit margins.
Analysing these costs helps managers spot inefficiencies. If administrative expenses are growing much faster than sales revenue, it is a clear warning sign that the business is becoming bloated.
Benchmarking this metric against industry peers helps ensure your support functions remain lean and cost-effective.
In practice
Real-world examples.
Example
A tech startup spends 15,000 pounds per month on Google ads, 5,000 pounds on the founder's salary, and 3,000 pounds on cloud software. Total monthly SG and A is 23,000 pounds.
Example
A local manufacturing SME pays 2,500 pounds monthly for its central office rent, 1,200 pounds for accountancy fees, and 800 pounds for office supplies, totalling 4,500 pounds in SG and A.
Example
A boutique clothing retailer spends 4,000 pounds a month on store staff wages, 1,500 pounds on window displays, and 2,000 pounds on business insurance, making their monthly SG and A 7,500 pounds.
Think of it
“SG and A is like the fuel, maintenance, and insurance needed to run a delivery van. The packages inside are the product, but you need all those supporting costs just to get the van moving.
Formula
Calculation
Total SG and A = Selling Expenses + General & Administrative Expenses
Example: If a firm has 40,000 pounds in marketing costs (Selling) and 60,000 pounds in admin salaries and rent (General & Administrative), the calculation is:
40,000 + 60,000 = 100,000 pounds total SG and A.Case study
Seen in the real world.
GreenLeaf, a fictional eco-friendly cleaning product company, noticed their profits were shrinking despite record sales. The founder, Sarah, decided to investigate the income statement. While production costs were stable, SG and A had ballooned significantly over the past year. Sarah discovered that general and administrative expenses had doubled due to expensive office upgrades, redundant software subscriptions, and rising administrative salaries. Selling expenses had also increased through expensive, untracked social media campaigns that failed to bring in new customers. By cutting unnecessary software, pausing low-performing ads, and moving to a smaller shared workspace, Sarah reduced SG and A by 25 percent. This targeted cost reduction immediately restored healthy profit margins without impacting the quality of the cleaning products themselves.
Watch out
Common mistakes.
- Treating SG and A as completely fixed costs that can never be reduced.
- Confusing direct production costs with general administrative overheads.
- Assuming that cutting SG and A always improves business health, even if it harms vital functions like customer support.
Questions
People also ask.
Is rent always considered an SG and A expense?
It depends on the space. Rent for a factory or warehouse where products are made goes into production costs. Rent for the corporate head office goes into SG and A.
How does SG and A affect net profit?
SG and A is subtracted from gross profit along with other expenses. Higher SG and A means lower net profit, assuming revenue stays the same.
Why is this category tracked separately from cost of goods sold?
Separating them allows managers to see how much it costs to make a product versus how much it costs to run the business and sell that product.
