How to Calculate COGS for TikTok Shop Products: The Complete Guide

Most TikTok Shop sellers get their Cost of Goods Sold (COGS) wrong — and it is costing them thousands in miscalculated profits and incorrect tax filings. If you are using just your factory price as COGS, you are overstating your margins by 30-50%.

This guide covers everything you need to know about calculating accurate COGS for your TikTok Shop business.

What Is COGS?

Cost of Goods Sold (COGS) represents the total direct cost of producing or acquiring the products you sell. It is the first and largest deduction from your revenue, and getting it right is critical for understanding your true profit margin.

What to Include in TikTok Shop COGS

Your COGS should reflect the full landed cost of each product:

ComponentExampleOften Forgotten?
Factory/supplier price$3.50 per unitNo
Ocean freight (per unit)$0.60-$1.20Yes
Air freight (per unit)$2.00-$5.00Sometimes
Import duties & tariffs0-25% of declared valueYes
Customs brokerage fees$0.10-$0.30 per unitYes
Product packaging$0.15-$0.50Sometimes
Quality inspection$0.05-$0.15Yes
Insurance$0.02-$0.10Yes

How to Calculate Landed Cost Per Unit

Landed Cost = Product Cost + Freight + Duties + Packaging + Insurance + Inspection

Example: Beauty Product

ComponentCost
Factory price (FOB Shenzhen)$3.50
Ocean freight (per unit, 2000-unit order)$0.85
Import duty (6.5%)$0.23
Customs broker fee$0.12
Custom packaging$0.35
Inspection$0.08
Total Landed Cost$5.13

Notice the landed cost ($5.13) is 47% higher than the factory price ($3.50). Using $3.50 as your COGS would overstate your margin by nearly 5 percentage points.

Per-SKU COGS Tracking

If you sell multiple products, each SKU needs its own COGS. A blended average across all products hides which items are profitable and which are money losers.

Pro tip: Your best-selling product might actually be your least profitable. Per-SKU COGS tracking reveals the truth.

COGS and Inventory Accounting

When you buy inventory at different prices over time, you need to choose an accounting method:

Common COGS Mistakes

  • Using factory price only: Ignoring freight, duties, and packaging understates COGS by 30-50%.
  • Forgetting sample costs: Free samples to affiliates are a real product cost.
  • Not updating COGS when suppliers raise prices: Your margins change even if selling price stays the same.
  • Mixing currencies without conversion: If you pay in RMB, convert at the actual exchange rate you paid, not today's rate.
  • Ignoring defective units: If 3% of your order is defective, spread that cost across the good units.

COGS Impact on Taxes

COGS is your largest tax deduction. On your Schedule C, COGS is deducted from gross receipts before calculating taxable income. Understating COGS means you pay more tax than you should.
