What the copart fee calculator calculates
Works out the fees on a marketplace or payment-processor transaction - percentage, fixed, referral, fulfilment and listing - and returns the seller’s net proceeds, the amount to charge to net a target, the buyer’s all-in total and the effective fee rate.
How to use this copart fee calculator
Enter Sale amount, Processor percentage fee (from your provider), Fixed fee per transaction (from your provider) and Marketplace referral / commission rate. Net proceeds to the seller updates as you type. Change one figure at a time to see what drives the result.
How the result is worked out
Open “How this is worked out” beside the result for the step-by-step calculation behind Net proceeds to the seller, Total fees and Percentage fee.
The method follows PayPal Merchant Fees (US), commercial transaction rate card, Amazon Seller Central, Selling on Amazon fee schedule (referral fees) and FBA fulfilment fees, Copart buyer fee schedule (member and internet bid fees, gate fee) and Percentage-plus-fixed fee inverse: gross = (net + fixed) / (1 - rate), the exact solution of net = gross - (gross x rate + fixed).
What you can compare
Change one input at a time to see how it affects Net proceeds to the seller, Total fees and Percentage fee. The inputs you can vary are Sale amount, Processor percentage fee (from your provider), Fixed fee per transaction (from your provider), Marketplace referral / commission rate, Flat fulfilment / buyer fee per order and Listing / gate fee.
Understanding Net proceeds to the seller, Total fees and Percentage fee
Fee schedules are set by the provider and change without notice, and many carry conditions (transaction size, currency, buyer location, product category, item size and weight). Confirm every rate against the provider’s current published fee schedule before relying on the result.
