Calculate a SKU price floor before marketplace fees erase margin. This product pricing tool includes COGS, packaging, shipping, marketplace fees, ad allowance, return reserve, break-even price, and target price before you choose a sales channel.
Direct answer
A marketplace seller needs more than cost plus markup. The safer price floor includes product cost, packaging, fulfillment, platform fees, payment processing, promotion, returns, and overhead before you write listing copy or run a discount.
Marketplace seller pricing example
If a seller pays $10 for the item, $0.80 for packaging, $5.20 for fulfillment, 8% marketplace fees, 3% payment fees, $4 in ads, and a 2% return reserve, the break-even floor is no longer close to COGS. The calculator shows whether there is still room for coupons, promoted listings, or better product-page copy.

How this calculator works
The calculator separates fixed per-order costs from percentage-based fees. Fixed costs include product cost, packaging, fulfillment, ad cost, and overhead. Variable fees include marketplace fees, payment fees, and a return or refund reserve.
This makes the page useful before platform-specific planning. Start with the general product pricing read, then compare TikTok Shop, Amazon FBA, Etsy, or another channel to see where the SKU has the healthiest room for ads, discounts, and listing experiments.
Next seller workflow
Once the SKU can support the target margin, use SKU to Sales to turn the same product facts into listing copy, SEO content, FAQs, ad hooks, and channel-specific experiments.

The practical product pricing calculator formula is fixed costs + variable fees + target profit. For marketplace sellers, that means COGS, packaging, marketplace fees, payment processing, shipping, ads, and return reserve must all be counted before you trust a target selling price.
Start with landed product cost, then add packaging, fulfillment, platform fees, payment processing, ads, return reserve, and overhead. After that, compare the break-even floor with the target price required for your target margin.
Use break-even price = fixed costs divided by one minus the variable fee rate. Fixed costs are product, packaging, fulfillment, ads, and overhead. Variable fees are marketplace fee rate, payment fee rate, and return reserve.
Markup compares selling price with product cost. Margin compares net profit with selling price after the full marketplace cost stack. That is why markup can look healthy while net margin is weak.
FAQ
Include COGS, packaging, shipping, marketplace fees, payment processing, ad allowance, returns, overhead, and target margin. That gives a more realistic price floor than markup alone.
Use this page first to test the SKU economics. Then use the eBay, Etsy, Whatnot, Amazon FBA, TikTok Shop, or Shopify calculator when platform-specific rules matter.
If the SKU clears break-even and target margin, send the price floor to the One SKU Content Pack Generator and build product-page copy that does not promise discounts the margin cannot support.
