Profit margin calculator
Ecommerce Profit Margin Calculator
Estimate true ecommerce profit after marketplace fees, fulfillment costs, product cost, duty, VAT, PPC, returns, and the other inputs that turn a sale price into real net margin.
Net profit = sale price - product cost - marketplace fees - fulfillment costs - duty - tax - PPC - return loss
- Sale price and product cost
- Marketplace seller fees
- Fulfillment and shipping costs
- Import duty and VAT assumptions
- PPC or advertising spend
What it calculates
One margin view, all the major inputs.
The calculator keeps the full cost stack together so the final margin reflects more than sale price minus product cost.
Connect sourcing cost, sale price, and landed-cost assumptions before margin is calculated.
Account for seller fees and category-based charges that reduce gross revenue.
Compare how shipping, warehouse, or fulfillment choices affect each unit sold.
Fold duty, VAT, and tax assumptions into the same profit view.
Include ad spend so profit is measured after acquisition costs.
Model refunds and return loss before they surprise the final margin.
How the calculation works
Profitlee turns the main costs sellers control and the platform fees they cannot avoid into one margin view, so you can compare products before placing an order.
If a product sells for $29.99, costs $8.00 to source, and carries marketplace, fulfillment, advertising, tax, and return costs, Profitlee estimates the net profit left after those deductions.
