Is Cost of Goods Sold an Expense? Accounting Guide

Cost of Goods Sold (COGS) represents the direct costs a business incurs to produce or deliver the products it sells. These costs include materials, labor, and other expenses directly tied to production. COGS is reported on the income statement and subtracted from revenue to calculate gross profit.

Is Cost of Goods Sold an Expense or a Separate Category on Your Income Statement?

Both.Cost of Goods Sold (COGS)is a business expense;FASB Concepts Statement No. 6includes it within the definition of expenses. However, it is adistinct type of expense.

COGS appearsabove operating expenseson the income statement because it is deducted from revenuebefore gross profitis calculated, rather than grouped with operating expenses like rent, payroll, or marketing.

That distinction matters for both financial reporting and tax analysis.

What Is Cost of Goods Sold (COGS)?

Cost of Goods Sold (COGS)is the direct cost of producing or purchasing the goods sold during a reporting period.

The standard formula is:

Beginning Inventory + Purchases – Ending Inventory = COGS

COGS can include:

Raw materials
Direct labor tied to production
Manufacturing overhead tied to units produced

It generally doesnotinclude:

Sales commissions
Marketing costs
Administrative overhead

Those are usually operating expenses, not COGS.

Is COGS a Business Expense? The Accounting Answer

Yes.UnderFASB Concepts Statement No. 6, cost of goods sold is a form of expense because it represents costs incurred in generating revenue.

It is classified separately from operating expenses because it reflects thedirect cost of revenue-generating activity, while operating expenses generally support the business more broadly.

Both COGS and operating expenses can reduce taxable income, but they are tracked separately because they serve different analytical purposes.

COGS vs. Operating Expenses: The Income Statement Structure

A basic income statement flows like this:

Revenue−COGS=Gross Profit

Gross Profit−Operating Expenses=Operating Income (EBIT)

A useful rule of thumb:

Costs that vary directly with production or units sold generally belong inCOGS
Costs that support the business regardless of sales volume generally belong inoperating expenses

That distinction can drive margin analysis.

What Costs Are Included in COGS?

For manufacturers

COGS often includes:

Raw materials
Direct labor (production workers)
Factory overhead, such as:
- Production facility rent
- Equipment depreciation
- Utilities tied to production

For retailers

COGS often includes:

Purchase price of inventory for resale
Inbound freight
Import duties
Other costs to bring inventory into saleable condition

These are direct product costs.

COGS for Service Businesses: Cost of Revenue

Service businesses may not have inventory, but they often haveCost of RevenueorCost of Services, which serves a similar function.

Examples may include:

Consultant salaries directly tied to client projects
Hosting or infrastructure costs tied to deliverables
Restaurant food and beverage costs
Contractor costs directly tied to customer work

These direct delivery costs are typically separated fromgeneral and administrative (G&A)expenses.

How Inventory Valuation Method Affects COGS and Taxes

Inventory method affects both COGS and taxable income.

FIFO (First In, First Out)

Oldest inventory is treated as sold first.

In rising-cost environments:

Lower COGS
Higher taxable income

LIFO (Last In, First Out)

Newest inventory is treated as sold first.

In rising-cost environments:

Higher COGS
Lower taxable income

Weighted Average

Uses an average inventory cost and tends to smooth fluctuations.

Whichever method you use should generally be applied consistently and, where required, disclosed.

Is COGS Tax Deductible?

Yes.COGS reduces gross income and is fully part of determining taxable business income.

For product businesses filingSchedule C, COGS is generally reported in its own dedicated section (Lines 35–42), separate from ordinary business expenses.

That is one reason keepingCOGS accounts separate from operating expense accountsis so important.

How to Record COGS in Your Accounting System

Perpetual inventory system

Under a perpetual system, COGS is typically recorded automatically when a sale occurs.

Periodic inventory system

Under a periodic system, COGS is calculated at period-end using:

Beginning Inventory + Purchases – Ending Inventory = COGS

A common chart of accounts setup includes separate COGS accounts such as:

Materials
Direct Labor
Manufacturing Overhead

Keep these separate from operating expense accounts for cleaner financial reporting, margin analysis, and tax reporting.
