Marketplace Profit Calculator

General seller margin

This flexible calculator works when you know your product cost, platform fee, payment fee, shipping cost, ad cost, sale price, and expected units sold.

Formula: price minus product cost, platform fee, payment fee, shipping, and ad cost

• Use platform fee for referral, transaction, or final value fee.
• Use payment fee for processor fees.
• Use ad cost per unit to model promoted listings or marketplace ads.
