Free tools get you to the first win. The full platform gives you research, SEO, mockups, creative production, and listing-ready assets in one connected flow.
Know exactly what goes into your pocket. Estimate transaction fees, listing fees, payment processing, offsite ads, net profit, and margin in seconds.
Includes the standard $0.20 listing fee per item sold.
Calculates the standard 15% offsite ads fee on total revenue.
The calculator does not stop at gross revenue. It walks the full chain from sale price down to the dollar amount that actually lands in your account.
Transaction, listing, payment processing, and an optional offsite ads fee - all calculated against your total sale price including shipping.
Your item cost and shipping cost are subtracted from revenue so you see net profit, not just gross. No hidden expenses left out.
The final margin tells you whether your price leaves enough breathing room for ads, discounts, and growth - or whether you are pricing too lean.
Profit is only one part of a healthy listing. Optimsy adds search demand, competition context, SEO Expert, mockups, and listing-ready assets in one connected workflow.
Margin is not just "profit per sale." It is the budget you have for ads, discounts, returns, packaging upgrades, and the next product launch.
Competitor prices reflect their costs, not yours. Anchor against your own cost structure first, then sanity-check against the market.
Materials, packaging, shipping, fees, and any platform tooling you pay for. If it touches the order, it belongs in the calculation.
If your margin barely clears the fee load, you cannot afford to run a sale or buy traffic. Pricing should fund growth, not just survive.
The $0.20 listing fee and $0.25 payment-fixed fee hit hardest on cheap products. Bundles often beat single-unit pricing here.
Two items sold together spread the flat fees over a larger ticket and almost always improve net margin, even at a discount.
