Gross margin is the percentage of revenue left after subtracting COGS. See the formula, how it differs from gross profit, and what a healthy margin looks like for TikTok Shop sellers.

Gross Margin

Gross margin (also called gross profit margin) shows the percentage of revenue you actually keep after covering the cost of the products you sold. It’s one of the quickest ways to see whether your pricing leaves enough room for a profitable business — before you even factor in ads, shipping, fees, or other expenses.

The Formula

Gross Margin (%) = (Revenue − COGS) ÷ Revenue × 100

First, subtract your Cost of Goods Sold (COGS) from revenue to get your gross profit in dollars.

Then, divide that gross profit by your total revenue and multiply by 100 to turn it into a percentage.

For example, a product that sells for $30 with a COGS of $12 produces $18 of gross profit, which is a 60% gross margin.

Gross Margin vs. Gross Profit

These two terms are related but not interchangeable, and mixing them up leads directly to pricing mistakes.

Metric What It Measures Unit
Gross Profit Dollar amount left after subtracting COGS from revenue Currency ($)
Gross Margin That same amount expressed relative to revenue Percentage (%)

Gross margin shows you how efficiently you earned it.A $10,000 gross profit can sound impressive until you realize it came from $100,000 in revenue (only a 10% margin). Compare that to the same $10,000 profit coming from just $20,000 in revenue (a 50% margin). Same dollars left over, completely different level of efficiency. Understanding operating profit vs gross profit extends this same logic one layer deeper, once other operating costs are factored in.

Why Gross Margin Matters for TikTok Shop Sellers

On TikTok Shop, gross margin is the number that determines how much room exists for everything that comes after the sale. Once gross margin is calculated, a seller still has to pay TikTok’s referral fee, affiliate creator commissions, ad spend, and fulfillment costs. A seller who doesn’t know their gross margin has no way to know whether their affiliate marketing commission rate or ad budget is sustainable.

This is the core reason margin planning has to start before a product launches, not after the first sales come in. Reviewing TikTok Shop fees alongside gross margin shows exactly how much of that margin gets absorbed by the platform before net profit is even calculated.

What Counts as a Good Gross Margin

Healthy gross margin benchmarks vary heavily by product category and business model.

  • Physical products with in-house manufacturing: 50% to 70% is common
  • Dropshipped or resold products: often 20% to 40%, since sourcing costs are higher per unit
  • Beauty, supplements, and apparel: frequently 60%+ due to lower unit production cost relative to price
  • Electronics and commoditized goods: often below 30% due to intense price competition

TikTok Shop sellers running dropshipping models typically operate on the lower end of this range, which is why margin discipline matters more for that business model than for sellers manufacturing their own product line. Comparing your numbers against highest profit margin businesses can help identify whether a category is structurally difficult to run profitably on the platform.

How to Improve Gross Margin

Sellers usually have three main ways to improve gross margin: increase the selling price, reduce the cost of goods per unit, or renegotiate terms with suppliers and fulfillment partners. Another practical move is bundling lower-margin products with higher-margin ones. This lifts average order value without pushing COGS up at the same rate.

Because TikTok Shop’s algorithm rewards products with strong conversion and engagement signals, sellers sometimes accept a lower gross margin on hero products to drive volume and visibility, then recover overall profitability through complementary items with wider margins. Tracking this properly requires looking at good operating profit margin targets alongside gross margin, since the two numbers tell different parts of the profitability story.

Tracking Gross Margin Automatically

Manually recalculating gross margin per SKU becomes unworkable once a shop has more than a handful of products, especially when COGS varies by supplier batch or shipping method. Best TikTok Shop profit trackers cover tools built specifically to calculate gross margin per order automatically, and the  TikTok Shop profit calculator

 can model gross margin scenarios before a pricing decision is finalized.
