Ecommerce unit economics
Marketplace break-even, price and units.
Use your own fee percentage and per-order charge to find the minimum price that covers variable costs, then test how many units cover fixed costs at an entered price.

Method and limitations
Source / provenance: user-entered assumptions. The calculator runs locally: break-even price is (unit cost + per-order fee) ÷ (1 − fee rate); units are fixed costs divided by contribution per unit, rounded up.
“Break-even” covers only the fixed costs and target profit you enter. Taxes, returns, storage, advertising, labour, and shipping belong in your variable or fixed cost inputs. This is a generic model, not an official marketplace calculation or live platform fee lookup.
