Fulfilment unit economics calculator

Methodology

Goods cost per order = cost of goods per unit × average units per order. Fulfilment cost per order = pick and pack + packaging + outbound shipping + storage allocation. Payment fee = average order value × payment fee rate. Expected return cost = return rate × return handling cost, charged across every order as a probability-weighted expectation rather than only to orders that come back. Contribution per order = average order value − goods cost − fulfilment cost − payment fee − expected return cost. Break-even order value is the order value at which contribution reaches zero, holding every cost constant. Returns are treated as a handling cost only: lost margin on unsellable returns, refund of shipping, and restocking write-downs are not modelled. Also excluded: customer acquisition cost, overheads, duties on cross-border orders, and any tax treatment. You supply every input: this site holds no live freight rates, transit times, or duty tables, and never estimates them for you. Results are an orientation model, not a quotation, and not customs, tax, insurance, or financial advice. Confirm duty rates, VAT treatment, and carrier terms with the relevant authority or provider before relying on them.
