Your supplier’s unit price is only part of what a product costs to bring to market. Allocate shipment-level expenses across the units you can actually sell, then see the selling price needed to cover additional order costs and a target margin.
How to use this calculator
Enter purchased and unsellable units, the total product purchase cost, freight, verified duties and brokerage, insurance, and other shipment costs. Use one currency throughout. Add per-sale fulfillment and fees for price planning. Use this model for one product or a comparable batch.
Formula and assumptions
Landed cost per sellable unit = total entered shipment costs ÷ (purchased units − unsellable units). Break-even price = fixed per-sale costs ÷ (1 − percentage fee rate). Target price = fixed per-sale costs ÷ (1 − percentage fee rate − desired margin).
Worked example
A shipment costing $13,500 in total with 1,000 units purchased and 20 unsellable units has a landed cost of about $13.78 per sellable unit. Adding $5 fulfillment, $0.30 fixed selling fees, and 15% percentage fees gives a break-even price of about $22.44 and a 20% target-margin price of about $29.35.
Common questions
Does the calculator determine import duties?
No. Enter verified duty, brokerage, and nonrecoverable tax amounts yourself. Tariff classification, country rules, and tax treatment are outside this calculator.
How should I handle a mixed shipment?
Allocate shared freight and other costs using a reasonable basis such as weight, volume, or value before analyzing each SKU. Simply dividing a mixed shipment equally can misstate individual product cost.
