Your COGS Analysis Blueprint

1

Identify your revenue and direct costs. This includes inventory purchases, raw materials, or direct billable labor used to create your product.

2

Exclude indirect expenses. Rent, marketing, and admin salaries are Operational Expenses (OpEx), NOT Cost of Goods Sold.

Use dynamic toggles to include easily forgotten costs like Freight-In and Packaging to ensure your Gross Margin is 100% accurate.

Why COGS Matters for Your Practice

Pricing Power & Margins

If you don't know your exact Cost of Goods Sold, your pricing strategy is just a guess. By isolating the direct costs of producing your product or service, you can accurately calculate your Gross Profit Margin. This ensures you have enough gross profit to cover your operational overhead and generate true net income.

Maximize Tax Deductions

COGS is deducted directly from your Gross Receipts to determine your taxable Gross Profit. Accurately tracking beginning inventory, purchases, and direct labor reduces your taxable income, keeping more of your hard-earned revenue out of the hands of the IRS.

Strategic COGS Frameworks

Select the strategic expense model that aligns with your specific industry structure.

Inventory Formula

Our retail and manufacturing tabs use the standard accounting formula: Beginning Inventory + Purchases - Ending Inventory.

Service Cost of Revenue

Services don't hold physical stock, so our Service tab calculates "Cost of Revenue" using direct billable labor and sub-contractors.

COGS Strategy FAQ

COGS refers to the direct costs of producing the goods sold by a company. This amount includes the cost of the materials and labor directly used to create the good. It excludes indirect expenses, such as distribution costs and sales force costs.

COGS is deducted from your gross receipts (revenue) to calculate your gross profit. Because it directly lowers your reported gross profit, an accurate and fully maximized COGS calculation directly reduces your taxable income, saving you money during tax season.

No. Marketing, advertising, rent for a retail storefront, and administrative salaries are considered Operating Expenses (OpEx). COGS strictly includes costs that are directly tied to the production or acquisition of the specific items you are selling.

Service businesses usually calculate a "Cost of Revenue" or "Cost of Services" instead of traditional COGS. This includes the direct wages paid to employees fulfilling the service, subcontractor fees for the project, and direct software licenses required solely for that client.

Yes. "Freight-In" (the cost to ship raw materials or wholesale products to your facility) is a direct cost of acquiring the inventory and should be added to your COGS. (Note: "Freight-Out" or shipping products to your customer is usually tracked as an operating delivery expense).

You only deduct the cost of goods that were *actually sold* during the period. If you bought $10,000 in product but $4,000 is still sitting on your shelf at the end of the year (Ending Inventory), you can only claim the $6,000 that left your store as COGS for that period.
