TikTok Seller Center shows GMV but not real profit. Discover the metrics Seller Center hides and how Dashboardly fills the gaps.
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.
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.
Your COGS should reflect the full landed cost of each product:
| Component | Example | Often Forgotten? |
|---|---|---|
| Factory/supplier price | $3.50 per unit | No |
| Ocean freight (per unit) | $0.60-$1.20 | Yes |
| Air freight (per unit) | $2.00-$5.00 | Sometimes |
| Import duties & tariffs | 0-25% of declared value | Yes |
| Customs brokerage fees | $0.10-$0.30 per unit | Yes |
| Product packaging | $0.15-$0.50 | Sometimes |
| Quality inspection | $0.05-$0.15 | Yes |
| Insurance | $0.02-$0.10 | Yes |
| Component | Cost |
|---|---|
| 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.
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.
When you buy inventory at different prices over time, you need to choose an accounting method:
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.
