Unit cost is the number buyers ask about first and understand least. A manufacturer quotes USD 9.50 per unit and the buyer compares it to their retail price target of USD 49.99, calculates a 5x margin, and decides the economics work. But that calculation ignores freight, Amazon FBA fees, return rate, and the cost difference between a first order at 300 units versus a repeat order at 1,000 units. This guide provides the actual cost components behind that USD 9.50 number — what drives each element, how it changes with quantity, and what a realistic per-unit cost looks like at each MOQ tier from 300 to 5,000 units.

What Packaging Choice Does to Unit Cost

Packaging is the second-largest variable after order quantity. Most buyers underestimate how much box specification affects per-unit cost — and how much it affects the buyer's perception of brand positioning.

True Landed Cost: From EXW to Amazon FBA

The EXW unit cost is only the starting point. Buyers who build their P&L on EXW cost consistently underestimate their actual landed cost. Here is a complete cost build-up for a mid-range dual-motor device at 500 units, shipping sea freight to Amazon FBA US:

First Order vs Repeat Order Economics

The economics of your first private label order are materially different from a repeat order. Understanding this difference is important for setting your initial budget expectation correctly.

First order costs that do not recur: sample order (USD 50–200 for 1–3 units before committing to bulk); packaging artwork design (USD 300–800 for professional designer); packaging print setup fees if any premium finishes are used (USD 100–400 one-time); brand trademark registration in target markets (USD 700–1,400 for US and EU combined); pre-shipment inspection if using SGS or QIMA (USD 300–500).

These one-time costs add approximately USD 1,500–3,300 to your first-order budget that will not appear in subsequent orders. At 500 units, this represents USD 3.00–6.60 per unit in amortised first-order costs. Your second order will have better economics even at the same production cost.

How to Use This Data

Use the cost tables above to build your P&L before contacting a manufacturer. Know your target retail price, your target platform (Amazon, Shopify, wholesale), and your capital budget. Then work backwards: if your retail price is USD 49.99 and your target gross margin is 55%, your maximum allowable landed cost is USD 22.50. That ceiling tells you which product tier is viable at which quantity and which packaging specification you can afford.
