Profit margin after fees
A product pricing calculator works out the selling price you should list a product at, starting from your real costs and the profit margin you want to keep. Unlike a plain markup tool, this calculator also subtracts the marketplace fee that platforms like Shopee, Lazada, Amazon, and TikTok Shop take out of every sale, so the price it gives you protects your margin after those fees, not before. Enter your product cost, shipping and packaging, any overhead, your target margin, and the fee percentage, and you get the exact price to charge.
The formula this calculator uses is: Selling Price = Total Costs / (1 - Marketplace Fee% - Target Margin%). Suppose your total costs are $13 (product $10 + shipping $2 + overhead $1), you want a 25% margin, and your marketplace charges a 10% fee. The maths is $13 / (1 - 0.10 - 0.25) = $13 / 0.65 = $20.00. At $20, the platform takes $2, your costs are $13, and you keep $5 profit, which is exactly 25% of the price. This is why pricing against margin instead of markup matters once fees enter the picture.
Many sellers set a price using only cost and markup, then watch their profit shrink when the marketplace deducts its cut. On a $20 item, a 10% fee is $2 gone before you count product cost. If you priced without accounting for that fee, your real margin lands well below target. Building the fee into the price up front is the difference between a healthy margin and selling at a loss. If you sell the same SKU across several channels with different fees, each channel needs its own price, which is where a profit margin calculator and per-channel pricing become essential.
Margin is profit as a percentage of your selling price; markup is profit as a percentage of your cost. This calculator prices on margin because margin is what actually survives after fees and tells you the share of each sale you keep. It still shows the equivalent markup on cost so you can sanity-check against supplier rules of thumb.

It depends on category and channel. Fashion and accessories often target 40-60% margins, electronics run leaner at 15-30% because of competition, and handmade or niche products can hold 60%+. Whatever you choose, make sure the margin covers marketplace fees, shipping, returns, and advertising. A target that looks healthy before fees can turn thin once a 10-15% commission comes off the top, so always price on the after-fee number this calculator gives you.
If you list on Shopee, Lazada, Amazon, and your own store, each platform takes a different fee, so the same target margin needs a different price on each. Managing that by hand across dozens or hundreds of SKUs is where mistakes creep in and margins leak. OneCart lets you set and update prices per channel from one dashboard, sync inventory in real time, and see profit by SKU across every marketplace, so your carefully calculated prices actually hold up in production.
