Frequently Asked Questions
How is profit per order calculated?
fees = price × (commission + payment %) + fixed fee; payout = price − fees; profit = payout − cost.
Which figures do I need?
Selling price, marketplace commission, payment processing fee, fixed fee per order, product and shipping cost. Take them from the same period and the same set of accounts or reports so the ratio is consistent, and check the example values as a guide to the units expected.
Which fees should I include?
Every fee your platform or provider charges on a sale: commissions, payment processing, fulfilment, storage, advertising and the expected cost of returns. Fee schedules change, so check the current rate card.
