How to use the marketplace commission calculator
Money flow of one sale
On a marketplace the buyer pays once but several parties are paid from that payment. The seller receives the item price minus the platform's commission and fees. The payment processor takes its fee. The platform keeps its commission, any fixed fee and any buyer service fee. This calculator splits one order into those parts and then multiplies it out.
Enter your fee model
- Seller's item price is the price the seller sets.
- Commission % is the share of the price the platform takes from the seller.
- Fixed fee per order is a flat charge to the seller, such as 0.25 per order.
- Buyer service fee % is added on top of the price paid by the buyer. Enter zero if you do not charge one.
- Payment fee has a percentage and a fixed part, matching how processors usually price card payments. The percentage applies to what the buyer pays.
- Choose who bears the payment fee.
Read the per-order result
The seller side shows payout after every deduction. The platform side shows revenue, any payment cost you absorb and net. Two quick gauges, your take rate and the percentage the seller keeps, summarise the deal. Sellers compare you with other platforms using exactly these figures, so keep the seller percentage competitive.
Look at scale
The table repeats the per-order maths at 100, 1,000, 10,000 and 100,000 orders per month, plus your own volume in bold. It shows gross sales, seller payouts and platform net. The note below it gives a yearly figure at your volume.
Using the numbers
- Test commission levels at your average price and at a low price; if the platform net falls below zero for small orders, add a fixed fee or a minimum price.
- Compare a high commission with no buyer fee against a lower commission plus a buyer fee.
- Revisit the model when your average price changes.
Fees are a product decision as much as a financial one, so check how the payout looks from the seller's side.
Frequently asked questions
What is a take rate?
It is the share of the item price that the marketplace keeps after costs. If a 60 item earns the platform 6.60 net, the take rate is 11 percent. It is the most common way to compare marketplace business models.
Should the seller or the platform pay the payment fee?
Both models exist. Charging the seller keeps platform margin predictable and is common. Absorbing it can make your fees look simpler and attract sellers, but it lowers your net, especially on small orders where the fixed fee is large.
What does the buyer service fee do?
It is a percentage added on top of the price that the buyer sees at checkout. The platform keeps it as revenue, and the payment processor also charges on it because the buyer pays it.
Why do small orders squeeze the margin?
A fixed per-transaction fee does not shrink with the basket. On a low price it takes a bigger bite out of the seller payout or platform net. A modest fixed fee on your side can offset that.
Does the calculator include refunds and chargebacks?
No. Refunds, disputes and tax add real cost in practice. Consider lowering the projected platform net by your expected refund rate when planning.
