What private label is
Private label is a product manufactured for a retailer and sold under that retailer's own brand instead of a national manufacturer's name. Costco's Kirkland Signature is the one everybody knows: it does well over $80B a year, which would rank it among the largest CPG companies on earth if it ever left the warehouse. Whole Foods sells 365, Target sells Good & Gather, Kroger sells Simple Truth and Private Selection. Same shelf, same category, different owner on the label.
The terms blur, so let me pin them. Private label, store brand, and own brand all mean the same thing: the retailer owns the brand. A national brand is the opposite, a manufacturer's brand sold across many retailers (think Annie's, RXBAR, Chobani). If you typed "private label meaning" because a buyer just told you they're putting a store-brand version next to yours, the rest of this page is the part you actually care about.
How private label and national brands compare
The reason retailers love private label is margin, and the reason brands fear it is the same number from the other side. A store brand skips the national brand's marketing spend and slotting demands, so the retailer keeps more of every dollar. Here's the same shelf, a 12 oz bag of tortilla chips, run two ways.
| Line | National brand | Private label |
|---|---|---|
| Shelf price (per unit) | $4.49 | $3.29 |
| Retailer cost (per unit) | $3.00 | $1.97 |
| Retailer gross profit ($) | $1.49 | $1.32 |
| Retailer gross margin (%) | 33% | 40% |
Look at what happens. The private label rings up $1.20 cheaper for the shopper, the retailer still pockets nearly the same gross profit dollars, and the margin rate jumps seven points. That gap is the entire business case for store brands, and it is why a buyer can be perfectly friendly to your face and still hand prime shelf space to their own label. They make more on it.
Where private label takes share
Private label runs around 20% of US grocery dollars overall, but the category average hides everything useful. The share swings hard by aisle. Commodity categories where the shopper sees no real difference between brands, milk, sugar, canned beans, trash bags, can run 40% private label or higher. Categories built on identity, formulation, or trust, premium beverages, supplements, pet food, run far lower, sometimes under 10%.
| Category | Private label share | Why |
|---|---|---|
| Milk | ~55% | Commodity, no perceived difference |
| Canned vegetables | ~40% | Price-driven, low brand loyalty |
| Salty snacks | ~18% | Brand identity matters, but eroding |
| Pet supplements | ~8% | Trust and formulation win |
For a national brand, the read is simple: the more your category looks like milk, the harder private label hits you. The more it looks like pet supplements, the more room you have. This is exactly the kind of call a buyer makes during a line review, which is why private label sits at the center of category management: the retailer is deciding how much of the shelf to give itself versus the brands.
Why private label matters to a brand-side analyst
When you read SPINS or Circana for your category, private label usually shows up as its own line, and ignoring it is a classic mistake. If your unit velocity is flat but private label in the category grew six points, you didn't hold serve, you lost share to the store brand and the category tailwind covered it. The headline number lied; the breakdown told the truth.
The other thing to track is the price gap. When a national brand's premium over the store-brand equivalent stretches past about 30%, switching tends to accelerate, especially in a soft economy. A brand that watches the gap between its shelf price and the private label sitting beside it, retailer by retailer, sees the switching risk building before it shows up in the sales line. By the time velocity drops, the shopper already moved.
Where Scout fits
Spotting private label gaining on you means reading your velocity and your share against the store-brand line in the same category, across every retailer, and not just at the total level where it averages out to nothing. Scout connects your SPINS or retailer data and lets you ask "where is private label taking my share" and "how wide is my price gap at each retailer" without rebuilding a pivot table every month. It measures the shift; it doesn't negotiate the shelf back for you. That part is still your job with the buyer.
The short version
- Private label (store brand, own brand) is a product made for and sold under a retailer's own name: Kirkland, 365, Good & Gather, Simple Truth.
- Retailers push it because it carries a higher margin rate while still delivering a lower shelf price to the shopper. That is the whole business case.
- Its share swings by category, near commodity levels in milk, single digits in pet supplements, so read it per category in syndicated data and watch your price gap before it costs you velocity.
