How much does a marketplace make?
Most online marketplaces charge sellers a commission of 5-30% per transaction. A marketplace doing $10,000 in monthly GMV at a 10% commission rate earns roughly $700 in net revenue after Stripe processing fees (2.9% + $0.30) and Prometora's platform fee (1.5% on Professional). Use the calculator below to project your own numbers, or read the commission rates guide for benchmark data by category.

When someone opens the link, the calculator automatically loads your commission rate, AOV, monthly orders, and selected plan. Great for sharing projections with co-founders or investors.
It factors in your commission rate, AOV, and Prometora fees to give you a realistic order target.
Once you exceed break-even, every additional order is pure profit (minus Prometora's small transaction fee). The calculator shows you exactly where this threshold is.
For example, if your GMV is $5,000 and your net revenue is $300, your profit margin is 6% of GMV. This helps you understand your take-home rate at a glance.
