US scenarios are converted using your exchange-rate assumption, not a live quote. They do not imply that these US platforms are available in Japan.
How the calculation works
Assumes seller-paid shipping, included in the item price. Shipping presets are estimates and exclude packaging. Withdrawal charges and platform-specific fee rounding are excluded. Comparisons with US platforms use an editable illustrative exchange rate.
Payout = item price + seller-collected shipping − fees. Profit = payout − item cost − shipping cost. Reverse mode finds the lowest listing price that reaches your selected payout or profit.
Estimates exclude unlisted charges. Reverse prices round up to the smallest currency unit that meets your target.
Compare platforms at the same sale price
Same item price, costs, and buyer-paid shipping. The current platform follows the selected controls; other rows use platform defaults. Required listing prices appear in reverse mode. Poshmark shipping is paid to the platform and excluded from seller revenue. Payment processors and marketplaces provide different services. Optional promotions and buyer fees are excluded.

Frequently asked questions
What does the target amount mean?
Choose payout to calculate the amount after platform fees but before costs. Choose profit to also subtract item and seller-paid shipping costs. Reverse mode finds the lowest listing price in cents (whole yen for JPY) that reaches your target, including fee thresholds.
Are these fees guaranteed?
No. The fee table states the region, assumptions, official source and verification status. Optional charges, account-specific pricing, taxes on fees and platform rounding can change the actual payout.
How does the comparison work?
All rows use the same item price and costs. The current platform follows your selected payment type and seller category; other rows use their defaults. Each platform retains its own fee base. The displayed verification status applies to each row; read the assumptions before comparing.
