How to Calculate Landed Cost Per Unit
The price your manufacturer quotes is not your cost per unit. It is usually around two thirds of it. Add packaging, testing, freight, wastage and the holding cost of stock before you set a price.
Why Brand Owners Get This Wrong
This guide is for brand owners in India setting prices for manufactured products.
A manufacturer quotes a per-unit price. It covers the manufacturing they do: formulation, production, filling and usually primary packing with components you supply or they source.
What it typically does not cover is the per-batch testing divided across your units, the freight from factory to your warehouse, the wastage you will inevitably have, the cost of holding stock for the months it takes to sell, and the write-offs from expiry and damage.
A brand owner who prices off the quoted figure believes their margin is one number and discovers it is substantially lower. By then the price is in the market and distributor terms are set, both of which are hard to change upward.
Working out the real figure before pricing takes an afternoon and is worth doing properly once.
Everything That Belongs in the Number
Work through each line.
| Cost Element | How to Allocate It |
|---|---|
| Manufacturing price per unit | As quoted |
| Primary packaging | Per unit, if you source it separately |
| Secondary packaging and cartons | Per unit |
| Labels and printed material | Per unit, at actual order quantity |
| Per-batch release testing | Total testing cost divided by batch size |
| Raw material testing | Where you commission it, allocated per unit |
| Inbound freight | Factory to warehouse, divided by units |
| Insurance in transit | Where applicable |
| Warehousing | Monthly cost times expected months held, per unit |
| Wastage and rejects | A percentage allowance, from experience |
| Expiry write-off | A percentage allowance based on shelf life and turn |
| Damage in transit and handling | A percentage allowance |
| Returns | A percentage allowance where you accept returns |
| Working capital cost | The cost of money tied up from payment to sale |
| Applicable taxes and duties | With professional advice on treatment |
Testing divided by batch size is the line most often missing, and at small batch sizes it is significant. A fixed release panel spread across a small first batch can add meaningfully to unit cost.
The Allowances People Omit
Each is a real cost with a real number.
Wastage
Production yield is not 100 percent, and you will also lose units to samples, damaged packs and quality holds. Allow a percentage rather than assuming zero.
Expiry Write-Off
Any product with shelf life generates write-offs. The slower it sells and the shorter its life, the higher the percentage.
Holding Cost
Warehouse space costs money per month, and stock held for eight months costs eight times what stock held for one month does.
Working Capital
You pay the manufacturer before you are paid by customers. That gap has a cost, whether you are paying interest or forgoing other use of the money.
Set each allowance from your own experience once you have it, and from a conservative estimate before you do. Revising them downward later because reality was kinder is a pleasant surprise; revising upward is a pricing problem.
Doing the Calculation
A workable sequence.
- Start with the manufacturer’s quoted per-unit price at your actual order quantity.
- Add every packaging component you source separately, at your actual order quantity.
- Total your release testing panel cost and divide by batch size.
- Add any raw material testing you commission, divided by units.
- Add inbound freight and insurance, divided by units.
- Estimate months of stock holding from batch size divided by monthly sales.
- Multiply monthly warehousing cost by those months and divide by units.
- Add a wastage percentage.
- Add an expiry write-off percentage based on shelf life and turn.
- Add a damage and returns percentage.
- Calculate working capital cost over the payment-to-sale gap.
- Take professional advice on tax and duty treatment.
- Total it. That is your landed cost per unit.
- Recalculate at a larger batch size to see how the figure moves.
What the Number Tells You
Use it for more than pricing.
It tells you your real gross margin at any given selling price, which is the basis for deciding whether a product is viable at all.
It tells you how much room you have for distributor and retailer margins, and whether the channel you intend to sell through is affordable. A margin structure that works for direct sales may not survive a two-tier distribution chain.
It tells you how much scale would help. Recalculating at double the batch size shows which cost elements are fixed per batch and therefore how much unit cost falls with volume. That is the argument for or against a larger second order.
And it tells you where the cost actually sits, which is often not where you assumed. For many small-batch products, testing and holding cost together exceed the packaging cost, which changes where you look for savings.
Checklist
Before setting a selling price.
- Use the quoted price at your actual order quantity, not a volume quote.
- Add every separately sourced packaging component.
- Divide the full release testing panel by batch size.
- Add raw material testing you commission.
- Add inbound freight and insurance per unit.
- Calculate months of holding from batch size and realistic monthly sales.
- Add warehousing cost for that period.
- Add wastage, expiry, damage and returns allowances.
- Add working capital cost over the payment-to-sale gap.
- Take professional advice on tax and duty treatment.
- Total to get landed cost per unit.
- Check the margin at your intended selling price.
- Check whether the channel margin structure survives it.
- Recalculate at a larger batch size to quantify the scale benefit.
- Revisit the figure whenever batch size, pack or supplier changes.

Frequently Asked Questions
Why is the quoted price not my cost?
Because it covers manufacturing, not the per-batch testing divided across your units, inbound freight, wastage, the cost of holding stock for months, or write-offs from expiry and damage. Those typically add a substantial amount.
Which cost line is most often missing?
Per-batch release testing divided by batch size. At small batch sizes a fixed testing panel adds meaningfully to unit cost, and it is almost always left out of early calculations.
What allowances should I include?
Wastage, since yield is never 100 percent and units are lost to samples and quality holds; expiry write-off based on shelf life and turn; damage in transit and handling; and returns where you accept them. Estimate conservatively before you have your own data.
Why does holding cost matter?
Because warehouse space costs money per month and stock held for eight months costs eight times what stock held for one month does. Calculate months of holding from batch size divided by realistic monthly sales.
What else does the number tell me?
Your real gross margin, whether your intended distribution channel’s margin structure is affordable, and how much unit cost falls at larger volumes. Recalculating at double the batch size quantifies the scale benefit.
