About the Profit Calculator
Revenue is vanity; profit is what you actually keep. Working out net profit, gross margin and markup from your price, cost and fees tells you whether a product is genuinely worth selling — and many sellers confuse margin with markup and misprice as a result.
This Profit Calculator turns your price, cost and fees into clear net profit, margin and markup figures, so you always know what you are really making.

How the Profit Calculator works
These calculators use the standard, published fee structures of the major marketplaces and platforms — Shopify, Amazon FBA, Etsy and eBay — including referral, transaction, payment-processing and fulfilment fees. By combining those with your product cost and price, they show your real profit and margin per sale rather than just revenue.
All calculations run privately in your browser.
Tips & best practices
- Margin and markup are not the same — a 50% markup on cost is only a 33% margin on price, so be clear which you mean.
- Include every cost, not just the purchase price, so your profit reflects reality.
- Aim for a margin that survives discounts, returns and ad spend, not just break-even.
Standards & accuracy
Based on the published fee structures of Shopify, Amazon, Etsy and eBay for realistic seller estimates.
Marketplace fees vary by plan, category and country and change over time, so treat results as close estimates. Confirm the exact figures against your own seller account before making decisions.
