What counts as COGS for a beauty brand

For measuring POAS, "cost of goods" means every cost that scales with each order you sell. Ad spend is not included, because it's the other side of the ratio. For a beauty brand, the formula can be a small part of what a unit really costs. The container, the extras in the box and the shipping can add up to more.

What goes in

Cost	Count it?	Why
Formula or bulk product from the lab or manufacturer	Yes	The base of unit cost
Primary packaging: jar, tube, pump, dropper	Yes	Per unit, and can cost more than the formula
Secondary packaging: carton, insert, shrink-wrap	Yes	Per unit and easy to leave out
Filling and assembly	Yes	Charged per unit or per batch
Inbound freight and duty	Yes	Part of landed cost
Samples, minis and gifts with purchase in the order	Yes	A cost of that order, not marketing
Pick, pack and outbound shipping you pay	Yes	Scales with orders
Payment processing fees	Yes	A share of every order
Stock written off at expiry or damaged	Yes, spread across units sold	Shelf life turns slow stock into a cost
Returns that can't be restocked	Yes, spread across all orders	An opened product can't be sold as new
Formula development and safety testing	No	Paid once per product, not per unit
Creator seeding and PR boxes	No	Marketing, not the cost of an order
Google Ads spend	No	It's what POAS divides by

Building one unit's cost

On a small order, shipping and extras can cost more than the product. That's why basket size matters so much for beauty POAS, and why a gift with purchase that makes sense above a spending threshold can lose money below it.

Three levels of accuracy

Selvra OS works with three tiers of cost data and shows which one a figure is based on.

T1: one flat margin (labelled "estimated")

One percentage for the whole catalogue. This is workable for a brand with a small range at similar price points. It misleads once the range mixes low-priced lip products with premium skincare, because the packaging and fill cost doesn't rise in line with the price.

T2: margin by category (labelled "approximate")

A margin per product type: skincare, makeup, fragrance, body, kits and sets. Kits and gift sets deserve their own category. They bundle several units' packaging into one price and can carry a very different margin from the products inside them.

T3: cost per product (labelled "verified" once synced)

Shopify's Cost per item field, per variant, read directly. Shade variants may share one cost; size variants won't. A travel size and a full size need their own cost entered.

Reading the benchmark above

The figure above is one listed company: e.l.f. Beauty's cost of sales was 29.3% of net sales in its fiscal year to March 2026. A company of that size buys formula and packaging at volumes a small Shopify brand can't match, so it is a reference point, not a target. What it does show is how much room a beauty product's margin can leave for the costs in the table above, and why those costs, not the formula, can decide whether an order makes money.

Common COGS mistakes in beauty

• Counting only the formula. Packaging and filling are per-unit costs too.
• Calling samples marketing. A sample in the box is a cost of that order.
• Ignoring expiry. Stock that runs out of shelf life is a cost of the stock that sold.
