Calculate your TikTok Shop profit margins. Factor in platform fees, shipping, ad spend, and COGS instantly. TikTok Shop Calculator Stop guessing your margins. Start knowing them. If you sell on TikTok Shop, you already know the feeling. You list a product at $29.99, it sells, and you think you just made money. Then the commission hits. Then the transaction fee. Then you remember shipping. And ad spend. By the time you open a spreadsheet to figure out what actually landed in your pocket, you've already moved on to the next product — still not sure if the last one was even profitable. That's the problem. TikTok Shop moves fast. Your pricing decisions shouldn't be based on gut feel. WHY MARGINS ARE SO HARD TO TRACK ON TIKTOK SHOP TikTok Shop isn't like a traditional e-commerce storefront. The fee structure is layered, and it changes depending on your category, your account status, and whether you're running ads. Here's what eats into every single sale: - Platform commission (typically 5%, but varies by category) - Payment processing / transaction fees (around 2.9%) - Shipping costs (which vary wildly depending on product weight, carrier, and fulfillment method) - Cost of goods sold (your actual product cost, including sourcing and manufacturing) - Advertising spend (TikTok Ads, Spark Ads, creator commissions) - Packaging, inserts, return reserves, and other hidden costs Most sellers don't account for all of these at once. They price a product, hope the math works, and only realize weeks later — when they pull a report — that they were breaking even or worse. This extension exists to fix that. One screen. All your costs. Instant clarity. WHAT THIS EXTENSION DOES TikTok Shop Profit Calculator is a lightweight Chrome extension that lives in your browser's side panel. Click the icon, punch in your numbers, and get a complete profit breakdown in seconds. No spreadsheets. No formulas. No switching between tabs to cross-reference fee schedules. Here's what you see after every calculation: Revenue — Your total top-line revenue based on selling price and units sold. Product Cost — Your cost of goods, multiplied by units. This is what you paid to source or manufacture the product. Shipping — The per-unit shipping cost you're absorbing, whether you offer free shipping to buyers or not. TikTok Commission — The platform's cut, calculated as a percentage of your selling price. Default is set to 5%, but you can adjust it to match your actual category rate. Transaction Fee — The payment processing fee TikTok charges on every order. Default is 2.9%, adjustable. Ad Spend — What you're spending on ads per unit sold. This is critical for TikTok sellers who rely on paid traffic. Other Costs — A catch-all for packaging, inserts, return reserves, prep fees, labeling, or anything else that chips away at your margin. Net Profit — The real number. What you actually keep after everything is deducted. Profit Margin — Net profit as a percentage of revenue. This tells you how efficient your pricing is. ROI — Return on investment, calculated against your total cash outlay (COGS + shipping + ads + other costs). This tells you how hard your money is working. HOW IT WORKS 1. Click the extension icon in your Chrome toolbar. The calculator opens in the side panel on the right side of your browser. 2. Enter your selling price, product cost, and shipping cost. 3. Adjust the commission and transaction fee percentages if your category uses different rates. 4. Add your per-unit ad spend and any other costs. 5. Set the number of units sold (default is 1, but you can model bulk scenarios). 6. Hit "Calculate Profit." That's it. You get a full breakdown instantly. The side panel stays open even if you click elsewhere in your browser, so you won't lose your data mid-calculation. WHY A SIDE PANEL, NOT A POPUP Most Chrome extensions use popups. You click the icon, a small window appears, and the moment you click anywhere outside it — it's gone. Your inputs vanish. You have to start over. That's a terrible experience for a calculator. You need to reference product pages, check shipping rates, look up ad dashboards — all while keeping your numbers visible. This extension uses Chrome's Side Panel API. The calculator stays pinned to the right side of your browser. You can browse TikTok Shop Seller Center, check your ad manager, look up supplier pricing on AliExpress — all while your profit calculator stays open and ready. No data loss. No re-entering numbers. Just keep working. PRESETS: SAVE YOUR PRODUCT CONFIGURATIONS If you sell multiple products, you don't want to re-enter cost structures every time. Save your frequently used configurations as presets. For example: - "Phone Case — AliExpress supplier" with $2.30 COGS, $3.50 shipping, $1.00 ad spend - "LED Strip Lights — domestic supplier" with $8.50 COGS, $5.99 shipping, $2.50 ad spend Load a preset from the dropdown, tweak the selling price, and calculate. It takes seconds to model different pricing scenarios across your entire catalog. You can save up to 20 presets. They're stored locally in your browser — nothing is sent to any server. CALCULATION HISTORY Every calculation you run is saved automatically. Open the History tab to see your last 50 calculations with timestamps, unit counts, profit amounts, and margin percentages. Click any history entry to reload those exact values into the calculator. This is useful when you want to revisit a product you analyzed last week, or compare how different pricing strategies performed. Clear your history anytime with one click. REAL SCENARIOS WHERE THIS HELPS Pricing a new product: You found a product on 1688 for $4.20 per unit. Shipping to your US warehouse is $2.80 per unit. You want to sell it for $19.99 on TikTok Shop. Is it worth listing? Plug in the numbers and find out before you order inventory. Evaluating ad profitability: You're running TikTok Ads and spending $3.50 per conversion on a $24.99 product. Is the ad spend killing your margin, or are you still profitable? The calculator shows you instantly. Comparing shipping methods: Should you use TikTok's fulfilled-by-TikTok shipping at $5.99, or your own 3PL at $4.20? Run two quick calculations and compare the bottom line. Negotiating with suppliers: Your supplier offers a lower price at 500 units. Plug in the new COGS, set units to 500, and see how the total profit picture changes at scale. Setting minimum viable price: Work backwards. If your costs are fixed, what's the lowest selling price where you still hit a 20% margin? Adjust the selling price field until you find it. Running seasonal promotions: TikTok Shop pushes mega sales events. If you drop your price by 15% for a flash sale, does the increased volume make up for the thinner margin? Model it. WHAT THIS EXTENSION DOES NOT DO It does not scrape data from TikTok Shop. It does not access your seller account. It does not read your browser history, track your activity, or send data anywhere. The only permissions it uses: - Storage — to save your presets, history, and daily usage count locally on your device. - Side Panel — to display the calculator in Chrome's side panel. That's it. No tabs permission. No host permissions. No network requests. Everything runs locally in your browser. FREE TIER The extension is free to use with a daily limit of 15 calculations per day. The counter resets every 24 hours. For most sellers evaluating a handful of products, 15 calculations per day is plenty. The limit is displayed in the header so you always know how many you have left. THE MATH BEHIND THE CALCULATOR For full transparency, here is exactly how every number is calculated: Revenue = Selling Price x Units Sold TikTok Commission = Revenue x Commission Rate (default 5%) Transaction Fee = Revenue x Transaction Fee Rate (default 2.9%) Total Costs = (Product Cost x Units) + (Shipping x Units) + Commission + Transaction Fee + (Ad Spend x Units) + (Other Costs x Units) Net Profit = Revenue - Total Costs Profit Margin = (Net Profit / Revenue) x 100 ROI = (Net Profit / (Product Cost + Shipping + Ad Spend + Other Costs) x Units) x 100 No hidden logic. No rounding tricks. Just straightforward arithmetic applied to every cost that matters. WHO THIS IS FOR - TikTok Shop sellers who want to stop guessing and start knowing their real margins. - Dropshippers who need to quickly evaluate whether a product is worth listing. - Brand owners running TikTok Ads who want to understand the true cost of customer acquisition. - Resellers comparing pricing across multiple products and suppliers. - Anyone selling on TikTok Shop who has ever asked: "Am I actually making money on this?"
