How this is calculated

Revenue = selling price + shipping charged, without tax. With tax-inclusive prices, tax = price − price ÷ (1 + rate).
Each fee is charged on the base you choose, so a 15% fee on a tax-inclusive price is larger than on the net price.
Returns: the refunded share of revenue is lost, the product goes back into stock, and the cost of one return is added for each returned order.
Profit = revenue kept − product cost − order costs − fees − return handling. Margin = profit ÷ revenue kept. Markup = profit ÷ total costs.
Break-even and target prices are solved exactly, including fee minimums and caps, then rounded up to the next cent so the target is never missed.

Assumptions

One item per order.
Fees are not refunded on returns.
Costs are entered without VAT you can reclaim.
Item and shipping use the same tax rate.
