One flexible profit model for marketplace sellers who need to compare products, platforms, and prices before listing.
How the math works
Use the number after every cost
This calculator shows the amount left after the costs that are easy to forget. Change the assumptions to match your marketplace, product, vehicle, or region instead of relying on a generic rule of thumb.
Profit margin = (selling price − product − shipping − packaging − platform fees − ads) ÷ selling price
Questions sellers ask
What is a good marketplace profit margin?
The right margin depends on product category, returns, advertising, and labor. Model all costs before deciding whether a percentage looks healthy.
Should marketplace fees be included in profit margin?
Yes. Platform, payment, advertising, shipping, packaging, and inventory costs all belong in your net margin calculation.
How do I compare two marketplace products?
Run both products with the same cost categories and compare net profit per order, margin percentage, and monthly contribution.
Fee assumptions and related tools
