How to use this Marketplace Fee Calculator

Enter your sale price, platform fees, payment fees, shipping, and product costs. The result estimates the unit economics of one order or transaction.

Formula

Net Profit = Sale Revenue + Shipping Charged − Marketplace Fees − Payment Fees − Product Cost − Shipping Cost − Other Costs

Different marketplaces charge fees on different bases. Some apply fees to item price only, while others include shipping and taxes. Use this as a fast planning estimate.

For better decisions, test conservative numbers. Include ads, packaging, returns, refunds, and shipping subsidies when they apply.

FAQ

What does this calculator estimate?

Estimate marketplace fees, payment processing costs, shipping, and net profit from a sale.

What formula does it use?

Net Profit = Sale Revenue + Shipping Charged − Marketplace Fees − Payment Fees − Product Cost − Shipping Cost − Other Costs

Should I use this for exact tax or accounting?

No. This is a planning calculator. Marketplace rules, tax treatment, refunds, and category-specific fees can change your actual payout.

Payouts often exclude product cost, inbound shipping, packaging, ads, returns, chargebacks, and other operating costs. This calculator estimates unit economics, not a full accounting statement.
