What is Cost of Goods Sold (COGS)?
Every business selling products needs to know its Cost of Goods Sold (COGS). COGS includes all direct costs to produce or purchase the goods you sell. This number helps determine your gross profit.
A Cost of Goods Sold Calculator simplifies this complex calculation. It ensures accurate financial reporting and better pricing decisions.
Why is COGS Important?
- Determines Gross Profit
Gross Profit = Revenue – COGS
Without knowing COGS, you can’t know your true profit. - Helps with Pricing
If COGS is $10 and you sell for $15, your gross margin is $5. - Required for Tax Reporting
The IRS requires COGS for income tax calculations. - Identifies Cost Problems
Rising COGS may mean supplier issues or production inefficiencies.
What’s Included in COGS?
Direct Costs (Included in COGS)
- Raw materials
- Direct labor (factory workers)
- Manufacturing supplies
- Shipping to get inventory
Indirect Costs (NOT Included in COGS)
- Marketing expenses
- Office salaries
- Rent
- Utilities (unless factory-specific)
How to Calculate COGS
The basic COGS formula is:
COGS = Beginning Inventory + Purchases – Ending Inventory
Let’s break this down:
- Beginning Inventory
Value of all inventory at start of period. - Purchases
Additional inventory bought during the period. - Ending Inventory
Value remaining at period end.
Example Calculation
A toy store has:
- Beginning inventory: $20,000
- Purchases: $50,000
- Ending inventory: $15,000
COGS = $20,000 + $50,000 – $15,000 = $55,000
This means $55,000 worth of toys were sold.
Different Inventory Valuation Methods
Your COGS changes based on which accounting method you use:
1. FIFO (First-In, First-Out)
- Assumes oldest inventory sells first
- Better when prices are rising
- Results in lower COGS, higher profits
2. LIFO (Last-In, First-Out)
- Assumes newest inventory sells first
- Better when prices are falling
- Results in higher COGS, lower profits
3. Average Cost Method
- Uses average cost of all inventory
- Smoothes out price fluctuations
- Most common for small businesses
