SG&A Expenses: Definition, Formula & Benchmarks
SG&A — Selling, General and Administrative expenses — is the largest operating cost line below gross profit for most companies. It is the pool of overhead that funds the sales force, management, marketing, and back-office that keep the business running. Understanding what belongs in SG&A, how to calculate it as a percentage of revenue, and what benchmarks by sector reveal is essential for reading any income statement or evaluating a company's cost discipline.
SG&A expenses are the operating costs not directly tied to producing goods — salaries, rent, marketing, and overhead. SG&A % of Revenue = SG&A / Net Revenue x 100. Lower is generally better — it signals operating leverage as the business scales. Apple (AAPL) FY2024: $26.1B SG&A on $391B revenue = 6.7% — exceptionally lean for a company at that scale.
What Counts as SG&A?
SG&A is a catch-all for indirect operating costs — the expenses required to run the business but not directly tied to making a specific unit of product. The line sits between gross profit and operating income on the income statement.
- Salaries and benefits (sales, management, back-office)
- Compensation for the sales force, executives, finance, HR, and all support functions not counted in COGS. Typically the largest single component of SG&A.
- Office rent and utilities
- Lease payments and operating costs for headquarters, regional offices, and sales offices. Capital-light models with remote workforces keep this near zero.
- Marketing and advertising
- Paid media, brand campaigns, trade shows, agency fees, and digital marketing spend. Some companies break this out separately; many fold it into SG&A.
- Legal and accounting fees
- Outside counsel, audit fees, compliance, and regulatory costs. These can spike during acquisitions, litigation, or periods of heavy regulatory scrutiny.
- Travel and entertainment
- Sales-related travel, executive travel, and client entertainment. A useful signal of how heavily the company relies on face-to-face selling.
- Software subscriptions and IT overhead
- SaaS tools, ERP systems, internal productivity software, and IT support costs that serve the administrative side of the business (not product delivery).
What is not in SG&A: cost of goods sold (COGS), research and development (R&D), and depreciation & amortization are typically reported as separate line items above or alongside SG&A. Some companies combine SG&A with R&D into a single "operating expenses" line — in that case, check the footnotes to separate them.
SG&A Formula
SG&A appears as a line item on the income statement. The two most useful calculations are the ratio to revenue (which normalizes across companies of different sizes) and the relationship between SG&A, gross profit, and operating income.
- SG&A % of Revenue
- SG&A / Net Revenue × 100. The standard ratio for comparing overhead efficiency across periods and peers. Lower and declining is the target for a scaling business.
- Operating Income = Gross Profit − SG&A − R&D − Other OpEx
- SG&A is the largest deduction from gross profit on the path to operating income. Reducing SG&A as a share of revenue directly expands operating margin.
Both formulas use figures from the same period's income statement. For cross-company comparisons, always use the percentage ratio — absolute dollar amounts are meaningless without normalizing for company size.
Worked Example: Apple (AAPL) FY2024
Apple's FY2024 income statement shows how SG&A sits between gross profit and operating income, and why Apple's exceptionally low SG&A ratio is a core driver of its 31.5% operating margin.
| Income Statement Line | Amount | % of Revenue |
|---|---|---|
| Revenue | $391B | 100% |
| − Cost of Revenue (COGS) | $211B | 54% |
| = Gross Profit | $180.7B | 46% |
| − SG&A | $26.1B | 6.7% |
| − R&D | $31.4B | 8% |
| = Operating Income | $123.2B | 31.5% |
Apple's 6.7% SG&A ratio is exceptionally low for a company of its size. For comparison, most consumer goods companies run SG&A at 25-40% of revenue. Apple achieves this partly through its direct-to-consumer retail model (which captures sales efficiency through Stores and apple.com) and partly through brand recognition so strong that relatively little paid selling effort is required. See our SG&A benchmarks by sector to compare Apple's ratio against its industry peers.
SG&A Benchmarks by Sector
SG&A as a percentage of revenue varies dramatically by industry. Asset-light businesses with strong brands and direct distribution channels run lean SG&A; industries requiring large sales forces or heavy marketing run much higher ratios.
| Sector | Typical SG&A % of Revenue | Why |
|---|---|---|
| Software / SaaS | 20-35% | High sales and marketing spend to acquire and retain subscription customers; large account management teams |
| Consumer Goods | 25-40% | Heavy brand advertising, distribution networks, and trade promotion spending to maintain shelf space and market share |
| Healthcare | 15-25% | Pharma companies spend heavily on physician detailing and DTC advertising; medtech companies invest in clinical sales teams |
| Financial Services | 30-50% | High compliance overhead, large back-office operations, and significant client acquisition costs in wealth management and insurance |
| Manufacturing | 10-20% | Relatively lean selling costs in B2B environments; most cost is in COGS; channel-dependent models vary widely |
| Retail | 15-30% | Store associate labor, marketing, and corporate overhead; e-commerce players run leaner than brick-and-mortar chains |

SG&A and Operating Leverage
Fixed SG&A is the engine of operating leverage — when revenue grows faster than SG&A, the ratio falls and margins expand. This is one of the most powerful drivers of profit growth in a scaling business.
Operating leverage works because much of SG&A is semi-fixed: salaries, office leases, and software subscriptions do not automatically rise in proportion to revenue. A company that grows revenue 20% while keeping SG&A flat sees its SG&A percentage fall by roughly 3-4 percentage points per year — directly expanding operating margin by the same amount without any change in gross profit.
The key metric to watch: SG&A as a percentage of revenue, trended over 3-5 years. A healthy scaling business shows this ratio declining over time. A company where SG&A% is rising every year — even if absolute dollars of profit are growing — is becoming less efficient and may face margin compression at maturity.
Example: A company with $500M revenue and $100M SG&A (20% ratio) grows revenue 20% to $600M. If SG&A stays flat at $100M, the ratio falls to 16.7% — a 3.3 percentage point improvement in operating margin from SG&A alone, adding $20M of incremental operating income on the same cost base.
When Rising SG&A Is a Red Flag vs. an Investment
Not all SG&A increases are equal. Context determines whether rising overhead is a warning sign or a rational growth bet. The key question is whether revenue is growing faster, at the same pace, or slower than SG&A.
- Red flag: SG&A rising faster than revenue
- When SG&A% climbs persistently while revenue growth lags, it signals cost discipline problems — management may be adding headcount, real estate, or marketing spend without commensurate revenue return. Watch for this in mature companies where the growth phase is over.
- Acceptable: SG&A rising into a new market
- Early-stage companies and those entering new geographies or verticals often intentionally spend ahead of revenue. Amazon ran negative operating income for years funding logistics and AWS infrastructure. The question is whether management has a credible path to SG&A leverage.
- Diagnostic: Read management commentary
- Every earnings call and 10-K discusses SG&A trends. Management should be able to explain why SG&A is rising (investing in X market, building Y capability) and when leverage is expected. Vague explanations for persistent SG&A inflation are a yellow flag.
Rule of thumb: in a healthy public company, SG&A% should decline or hold flat as the company scales. If a company doubles revenue over five years but SG&A% has not improved, ask whether the business model has genuine operating leverage or whether costs are structurally variable.
SG&A vs. COGS: The Key Distinction
COGS (Cost of Goods Sold) and SG&A are both expenses on the income statement, but they measure fundamentally different things and appear at different levels of the P&L.
COGS is a product cost — it is directly tied to producing the specific units sold in a period. When you sell a product, the COGS associated with that product flows to the income statement. COGS includes raw materials, direct labor, and manufacturing overhead. It is subtracted from revenue to arrive at gross profit.
SG&A is a period cost — it is expensed in the period it is incurred, regardless of how much was sold. The CEO's salary, the lease on headquarters, and the annual software subscriptions all hit the income statement in the period they occur, whether the company ships one unit or one million. This timing difference matters for understanding how margins respond to changes in volume.
The practical implication: a company facing a volume decline will see gross margin compress as fixed COGS (manufacturing overhead) spreads over fewer units, while SG&A hits the income statement at the same absolute level regardless of how much was sold. Both effects hit operating income, but through different mechanisms. For a detailed look at the income statement waterfall from gross profit to operating income, see our operating income guide.
