SG&A (Selling, General & Administrative) expense is the bucket of operating costs a business incurs that are not directly tied to producing its product or service. It typically appears as a single line (or small section) on the income statement and sits between gross profit and operating income.

What is SG&A expense?

In simple terms:
SG&A = all the “keep the lights on and sell stuff” costs that are not production or cost of goods sold (COGS).

These are the expenses you’d still have even if your factory shut down for a week, as long as the company continues to exist and run its front office and sales operations.

Main components of SG&A

Most companies break SG&A into three mini-buckets (even if they don’t show each one separately on the income statement):

  1. Selling expenses (to win customers)
    • Sales salaries and commissions
    • Advertising and marketing (online ads, campaigns, events)
    • Travel, meals, and entertainment related to sales
    • Sales software (like CRM tools) and sales support costs
  1. General expenses (to keep the business running)
    • Office rent and other facility costs not tied to production
    • Utilities (electricity, water, internet) for non-production areas
    • Office equipment (computers, phones, servers) and supplies
    • Insurance and other general overheads
  1. Administrative expenses (to manage and control the company)
    • Executive and administrative staff salaries and benefits
    • Accounting, finance, HR, legal, and IT costs
    • Professional fees, litigation costs, and some depreciation on office assets

Some companies also include certain depreciation and amortization in SG&A if those relate to offices and admin equipment rather than production machinery.

SG&A vs other key costs

Here’s where SG&A sits compared with other common expense categories:

[2][1] [5][7][1] [2][5]
Category What it covers Where it appears
COGS Direct costs to make/provide the product or service (materials, direct labor, production overhead). Above gross profit on the income statement.
SG&A Selling, general, and administrative costs not tied directly to production (sales, admin, overhead). As part of operating expenses, below gross profit.
Other OPEX Sometimes R&D or separate lines like restructuring, depending on company practices. Also within operating expenses, often separate from SG&A.
Many sources casually call SG&A “operating costs,” but technically SG&A is usually a major **portion** of operating expenses, alongside items like R&D in some businesses.

Why SG&A expense matters

SG&A is closely watched in every earnings season and board meeting because:

  • It directly reduces operating profit and net income.
  • It’s often more controllable in the short term than COGS (for example, a company can freeze hiring or cut marketing).
  • In tougher economic periods (like rising inflation and slower demand), companies look hard at SG&A “fat” to protect margins.

Investors also track SG&A as a percentage of revenue (an SG&A ratio) to see if a business is scaling efficiently or overspending on overhead as it grows.

Simple SG&A example (story style)

Imagine a small consulting firm for Q4:

  • Selling costs:

    • Sales salaries and commissions: 45,000
    • Digital ads: 12,000
    • Client travel & entertainment: 8,000
    • CRM software: 3,000
      → Selling total: 68,000

  • General costs:

    • Office rent: 18,000
    • Utilities: 2,400
    • Office supplies: 1,800
    • Insurance: 3,600
    • Legal fees: 5,000
      → General total: 30,800

  • Administrative costs:

    • Executive salaries: 90,000
    • Accounting: 24,000
    • HR: 8,000
    • IT infrastructure: 6,500
      → Administrative total: 128,500

Total SG&A = 68,000 + 30,800 + 128,500 = 227,300 for the quarter.

If revenue is 1,000,000 in that period, SG&A is about 22.7% of revenue, a ratio management and investors will pay close attention to over time.
