Calculate ecommerce profit margins across 6 currencies, with a full cost breakdown.
Enter a selling price and product cost to see the profit analysis.
A product's sale price minus its cost isn't your real profit -- platform fees, payment transaction fees, shipping, and tax all take a bite before money actually lands in your pocket. This calculator itemizes every one of those costs against your revenue, showing true profit and margin rather than the misleadingly simple "price minus cost" figure many sellers mistakenly rely on.
Enter your sale price, product cost, per-unit shipping cost, platform fee percentage (like a marketplace's commission), payment transaction fee percentage, tax rate, any other per-unit cost, and quantity sold. Select your currency from 6 supported options (INR, PKR, USD, GBP, EUR, AED).
Total Revenue = Price × Quantity
Platform Fee = Total Revenue × Platform Fee %
Transaction Fee = Total Revenue × Transaction Fee %
Tax = max(0, (Total Revenue − Total Product Cost)) × Tax Rate %
Profit = Total Revenue − (Product Cost + Shipping + Platform Fee + Transaction Fee + Tax + Other) (shipping and other costs applied per unit)
Margin % = (Profit ÷ Total Revenue) × 100
A deliberate design detail: tax is calculated only on the positive gross margin (revenue minus product cost), not on your final net profit after all fees -- and only when that margin is actually positive. If your product cost exceeds revenue, no tax is applied. Shipping and "other" costs are multiplied by quantity, since they're incurred per unit sold.
Ecommerce sellers pricing a product on a marketplace with a known commission structure. Anyone comparing profitability across different platforms with different fee schedules, or checking whether a bulk order's shipping and per-unit costs still leave a healthy margin.
This is a planning estimate based on the figures you enter -- it doesn't account for returns/refunds, chargebacks, advertising spend, or fixed overhead costs (rent, salaries) not tied to a specific unit sold. All currency amounts are displayed with the same number formatting style regardless of currency selected; only the currency symbol changes.
The page's example shows a healthy result, so here is a hypothetical tight one. A product sells for 20 with a cost of 15, shipping of 4 per unit, a 15% platform fee, a 3% transaction fee, no tax, and a quantity of 1. Platform fee is 3.00 and transaction fee is 0.60. Costs total 15 + 4 + 3.00 + 0.60 = 22.60, so profit is 20 - 22.60 = -2.60, a margin of -13%. On paper the item has a 5 unit gap between price and cost, yet it loses money. This is the exact trap the calculator is designed to expose.
Price 30, cost 12, shipping 3, platform fee 8%, transaction fee 2%, tax rate 10%, quantity 10. Revenue is 300, product cost 120, shipping 30, platform fee 24, transaction fee 6, and tax is 10% of the 180 gross margin, which is 18. Total costs are 198, leaving profit of 102, or a 34% margin.
For pricing that affects your tax filings, VAT or sales tax registration, or cross-border rules, consult an accountant or your tax authority. This tool is a planning aid only.
This calculator applies tax to the gross margin (revenue minus product cost) before other fees are subtracted, matching how many sales/VAT tax structures actually work -- tax on the sale margin, not on your post-fee net profit.
Per unit -- both are multiplied by your quantity, since they represent a cost incurred for each individual unit sold, not a one-time flat cost.
No -- add any ad spend as part of your "other" per-unit cost if you want it reflected, or track it separately if it's a fixed campaign cost not tied to individual units.
Yes. If your costs and fees exceed revenue, the result shows a negative profit and margin, and no tax is applied because there is no positive gross margin.
Divide the monthly amount by the units you expect to sell and enter it in the Other per-unit field, or track it separately from this calculation.
No. Currency only changes the symbol shown. Enter all amounts in the same currency yourself.
It varies widely by product type and business model, so there is no single right number. Use the calculator to see what you are actually earning and decide what is sustainable for you.
