Contract Manufacturing Cost Calculator

True landed cost per unit.

Calculate contract manufacturing landed cost per unit including production, tooling, shipping, and import duty. Free educational tool.

What this tool does

Landed cost per unit from a contract manufacturer combines manufacturing, tooling amortised across the order, shipping, and import duty into a single per-unit figure. You enter the order quantity, per-unit manufacturing cost, tooling allocated per unit, shipping per unit, and import duty percentage. The calculator then estimates your total landed cost and breaks it down to a cost per unit. Manufacturing cost typically has the largest impact on the final figure, though tooling and duty can shift the result meaningfully depending on order size and supplier location. This calculation is useful for comparing quotes from different manufacturers or modelling how order volume affects unit economics. The result assumes duties apply only to the manufacturing component and does not account for brokerage fees, local taxes, or storage costs that may apply in your situation.

Contract manufacturing cost is more than the factory quote. Landed cost includes per-unit manufacturing, amortized tooling, ocean/air shipping, and import duties. Most product founders focus only on unit cost and get surprised when landed cost runs (commonly cited at 30-60%) higher than the factory quote due to shipping and duties.

5,000 units at 8/unit manufacturing + 2/unit tooling amortization + 1.50/unit shipping = 11.50/unit before duty. Import duty typically 3-12% depending on product category, applied to manufacturing + shipping value. At 8% duty: 0.76/unit extra. Total landed cost 12.26/unit. Most factory quotes show only 8/unit - the 4+ gap is where founders go wrong on margin math.

Tooling amortization matters for small runs. 20,000 tooling for 5,000 first order = 4/unit. Second order of 5,000 uses same tooling = 0/unit more. So first order true cost much higher; subsequent orders drop significantly. Factor this when pricing first-run vs re-order to avoid either overpricing first run or underpricing re-orders.

Run it with sensible defaults

Using units per order of 5,000, per-unit manufacturing cost of 8, tooling per unit of 2, shipping per unit of 1.5, the calculation works out to 12.14. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Units per Order, Per-Unit Manufacturing Cost, Tooling per Unit, Shipping per Unit, and Import Duty % — do not pull with equal force.

How the math works

Base = units × (mfg + tooling + shipping). Duty = units × mfg × duty %. Total = base + duty. Per-unit landed = total ÷ units.

What to do with a low result

A disappointing result is information, not a judgement. Pick the single input that dragged the figure down most and focus the next quarter on that one factor. Breadth-first improvement rarely works; depth-first on the worst input usually does.

What this doesn't capture

The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.

Example Scenario

5,000 units × (££8 + ££2 tooling + ££1.5 ship) + 8% duty = 12.14.

Inputs

Units per Order:5,000
Per-Unit Manufacturing Cost:£8
Tooling per Unit:£2
Shipping per Unit:£1.5
Import Duty %:8
Expected Result12.14

This example uses typical values for illustration. Adjust the inputs above to match a specific situation and see how the result changes.

Sources & Methodology

Methodology

Base = units × (mfg + tooling + shipping). Duty = units × mfg × duty %. Total = base + duty. Per-unit landed = total ÷ units.

Frequently Asked Questions

Why is landed cost so much higher than factory quote?
Factory quotes exclude shipping, customs, duties, inspection fees, payment processing. For cheap products (1-5 factory), landed cost is often 2-3x factory quote. For expensive products (50+ factory), landed cost is usually 10-20% higher.
Tooling cost per unit?
Tooling 5k-50k typical for simple products. Amortized over first order only if single-use; over expected lifetime orders if reusable. Many founders wrongly put first-order tooling in 'per unit cost' making subsequent orders look artificially cheap.
How to reduce import duty?
Design around lower-duty HS codes where possible. Use trade preference programmes has with many countries post-Brexit). First Sale valuation (declare factory price, not importer's price) can reduce duty 10-20% but needs documentation.
Ocean vs air shipping?
Ocean 0.50-2/unit depending on volume, 4-6 weeks transit. Air 2-10/unit, 3-7 days transit. Ocean for predictable sales, air for launches/reorders where speed matters. Many businesses ship 80% ocean, 20% air to balance.
