Marketplace Fee & Points Calculator
Calculate net received after selling fees and point rewards on Japanese marketplaces. Reverse-calculate listing price from a target net. Everything stays in your browser.
How to Use the Japan Marketplace Fee Calculator
Currency: every amount on this page is Japanese yen (JPY, ¥) and is rounded to whole yen, because the presets are Japanese marketplaces. There is no currency selector — if you work in another currency, convert to yen first (or use "Custom" purely as a percentage calculator).
Pick a marketplace preset, enter the listing price or the net amount you want to receive, and add any point reward rate if it applies. The selling fee, net revenue and point-adjusted amount update live.
Use this before listing an item on a Japanese flea-market or auction app, or when deciding what listing price is needed to keep a target profit after platform fees.
Example
Mercari listing ¥3,000, 10% fee, 0% points: fee ¥300, net ¥2,700. With 5% points: +150 pts → ¥2,850 equivalent.
Japan-style marketplace fees
The presets are Japan's flea-market and auction apps — Mercari, Rakuma, Yahoo! Flea Market (formerly PayPay Flea Market) and Yahoo! Auctions — which take a percentage of the sale price (Mercari, for example, charges 10%; Rakuma uses a tiered rate of 4.5–10% based on your recent sales, so enter the rate shown in your app). Amounts are in yen, and "points" are the loyalty points these apps credit back, worth ¥1 each. Rates change and can vary by category, so treat the presets as a starting point and confirm the current fee on the platform. For a marketplace that isn't listed, choose "Custom" and enter its rate.
Good For Sellers in Japan
- Checking whether a listing price still leaves enough net revenue after fees.
- Working backward from a target net amount to a practical sale price.
- Comparing Japanese marketplace fee presets before choosing where to list.
Preset Sources and Excluded Costs
Preset rates and rounding are checked against official guidance for Yahoo! Flea Market proceeds, Yahoo! Auctions seller fees, and Rakuma selling fees (last checked July 14, 2026). Confirm the rate and any coupon actually shown in your account before listing.
The estimate includes listing price, selling fee, and the point rate you enter. It excludes shipping, payout or payment fees, packaging, optional promotion, tax obligations, and category-specific charges. Subtract those separately when comparing true proceeds.
Meaning of the Reverse Calculation
Net-target mode repeatedly applies the selected platform's integer-yen rounding and finds the lowest listing price that reaches the target. It does not assess campaign caps, point expiry, buyer costs, or the likelihood of a sale. The final transaction screen takes priority.
