Before setting shipping
- Run the full Mercari calculator with the real item price, category, and buyer-paid shipping charge.
- Enter the actual label cost after carrier discounts, packaging, insurance, and signature add-ons.
- Check whether free shipping raises conversion enough to offset the seller-paid label cost.
- Use the USPS shipping tool when the label, packaging, or add-on cost is the unknown part of the listing.
Check Mercari shipping against fee data
Shipping treatment changes payout only after the marketplace fee model is known. Use the Fee Index for same-input marketplace rows, Fee Changes for recent policy updates, and Seller Reports for dated summaries before citing how shipping affects seller fees.
After the source check, keep the exact buyer-paid shipping, seller label cost, and packaging inputs in the shipping calculator or platform fee calculator.
Price the listing after shipping
Once the shipping setup is clear, run the platform calculator with real category, item cost, label cost, and buyer-paid shipping inputs. Use break-even when free shipping needs to be folded back into the sale price.
