Understanding Your Mercari Seller Fees
Selling on Mercari can be a great way to declutter or build a reselling business, but understanding the fee structure is crucial for ensuring you actually make a profit. Unlike straightforward cash transactions, online marketplaces involve various deductions that affect your final payout.
Current Mercari Fee Structure (2024 Update)
Mercari has undergone significant changes in its fee policies recently. While historically known for a flat 10% selling fee, policies can vary based on region and recent updates.
Selling Fee: In a major update for the US market, Mercari eliminated the selling fee for listers, bringing it down to 0%. This means you no longer pay a percentage of the item's sale price just for selling it. However, older accounts or other regions may still see the traditional 10% fee.
Payment Processing Fee: Standard online transactions incur processing fees. While Mercari shifted many fees to buyers recently, standard payment processing logic usually involves a rate around 2.9% + $0.50 per transaction.
Direct Deposit Fees: Note that while listing might be free, transferring money out via Direct Deposit may incur a flat fee (e.g., $2.00) depending on the amount and current policy.
How to Use This Calculator
To get an accurate estimate of your earnings:
Sale Price: Enter the final price the item sold for (excluding taxes/shipping charged to buyer).
Shipping: Enter the shipping cost. Crucially, select whether You (Seller) or the Buyer is paying. If you offer "Free Shipping," you are paying for it out of your earnings.
Item Cost: Enter how much you paid to acquire the item. This is essential for calculating your actual "Net Profit" versus just your revenue.
Fee Adjustments: We have preset the fields to 0% Selling Fee and standard processing rates, but these are editable so you can adjust for specific promotions or policy changes.
Optimizing Your Profit
To maximize your return, consider the weight of your items carefully. Shipping costs are often the largest deduction for low-value items. If the profit margin is slim (less than $5), consider bundling items together to save on shipping overhead and processing limitations.
