Gross Margin vs Markup for Baby Formula Retailers
Quick answer: markup and gross margin are not the same percentage. Markup compares profit with cost; gross margin compares profit with selling price. Retailers that confuse the two can set prices below the margin target they intended.
Gross margin vs markup
| Metric | Formula |
|---|---|
| Gross profit | Selling price − cost |
| Markup % | Gross profit ÷ cost × 100 |
| Gross margin % | Gross profit ÷ selling price × 100 |
Example: an 8-box case
Assume a retailer's effective cost is $30 per box and the planned retail price is $40.
- Gross profit per box = $10
- Markup = $10 ÷ $30 = 33.3%
- Gross margin = $10 ÷ $40 = 25%
The same transaction therefore has a 33.3% markup but only a 25% gross margin.
Use landed cost, not only product cost
For commercial planning, the relevant cost base may include more than the supplier's case price. Shipping, duties, payment costs and other buyer-side expenses can affect the effective landed cost.

Why case size affects working capital
A larger case can reduce unit cost but requires more cash up front. If the SKU sells slowly, a higher case quantity can also increase the risk of carrying stock too close to expiry.
Margin therefore needs to be considered alongside sell-through, shelf life and reorder frequency.
Set a target margin by SKU, not by brand
Different stages and products can have different landed costs and different local retail prices. Applying one fixed retail price rule across an entire brand can create inconsistent margins.
Retail margin checklist
- Calculate current product cost per box.
- Add allocated freight and buyer-side costs.
- Set the intended retail selling price.
- Calculate both markup and gross margin.
- Check whether the case quantity matches expected sell-through.
- Recalculate when supplier price or shipping changes.
Convert a target margin into a selling price
If a retailer starts with a target gross margin rather than a selling price, the calculation is:
Selling price = landed cost ÷ (1 − target margin)
For example, if landed cost is $30 and the target gross margin is 25%, the implied selling price is $30 ÷ 0.75 = $40.
Why promotions can compress margin quickly
A discount is applied to selling price, not to cost. If a $40 item with a $30 landed cost is discounted by 10%, the new selling price is $36 and gross profit falls from $10 to $6. Gross margin falls from 25% to about 16.7%.
This is why promotion planning should use the landed-cost model rather than a headline markup percentage.
Track contribution beyond gross margin
Gross margin is useful for comparing products, but a complete commercial model may also consider payment fees, fulfilment costs, returns, marketplace fees and customer-acquisition costs. Those items sit outside a simple product gross-margin calculation but can materially change profitability.
Frequently asked questions
Is 30% markup the same as 30% gross margin?
No. They use different denominators. A 30% markup produces a lower gross-margin percentage.
Should shipping be included in cost?
For a landed-cost calculation, yes: allocate the relevant order-level shipping and other buyer-side costs across the units.
Does gross margin include overhead?
Gross margin is usually calculated before operating overhead such as rent, payroll and marketing. Businesses may use additional profitability metrics beyond gross margin.
