Turn over a box of Advil and the pharmacy’s own ibuprofen next to it, and the first line of the Drug Facts panel reads the same on both: ibuprofen 200 mg. Same drug, same dose, and usually a smaller number on the shelf tag for the store version. That little white box settles more store-brand questions than any taste test.
Plenty of shoppers have already made the switch. Store brands hit a record $282.8 billion in US sales in 2025, according to the Private Label Manufacturers Association and the research firm Circana, and their share of units sold climbed to 23.5%. That’s close to one in every four items Circana tracked.
The cheaper label doesn’t win everywhere, though. It wins where the package lets you prove two products are the same, and it gets riskier where the package can’t tell you anything useful. Here’s how that sorts out aisle by aisle, starting with the math.
Do the unit price math yourself
Unit price tags are the fastest way to compare a 24-count box with a 100-count bottle, but you can’t count on them. No federal rule requires them. The National Institute of Standards and Technology says unit pricing is decided state by state, so some stores show it on everything, some on a few items and some not at all. Even where the tags exist, two products on the same shelf can be priced in different units, one per ounce and the other per count.
So do the division on your phone. A made-up example with round numbers: a name-brand bottle of 100 tablets at $10 works out to 10 cents a tablet, and a store-brand bottle of 300 at $15 works out to 5 cents. The bigger bottle looks more expensive on the shelf and costs half as much per dose. The reverse happens too. A name brand on sale with a digital coupon can dip below the store label for a week, so compare on the day you buy instead of from memory.
Medicine: match the ingredient and the amount
The FDA requires every over-the-counter drug to carry a Drug Facts label that names each active ingredient and how much of it is in each tablet, capsule or teaspoon. That’s the line to compare. Loratadine 10 mg is the Claritin dose, cetirizine 10 mg is Zyrtec, and fexofenadine 180 mg is the 24-hour Allegra. When the store box lists the same ingredient at the same amount in the same form, you’re holding the same medicine.
What can differ is the inactive stuff. The FDA says a generic has to match the brand in dosage form, strength, route, quality and performance, but it may use different colors, flavors and fillers. For most people that changes nothing. If you’ve ever reacted to a dye, read the inactive ingredients on both boxes before switching, which takes about ten seconds.
The real trap is trusting a brand name instead of the panel. Unisom SleepTabs contain doxylamine succinate 25 mg, while Unisom SleepGels contain diphenhydramine 50 mg, the same ingredient as Benadryl. One brand, two different drugs. A store’s “compare to” sticker points at one specific product, so check it against the exact box you used to buy.
Also watch the combination products. Many cold and flu formulas include acetaminophen, and poison control centers warn against taking two products with the same active ingredient. Store-brand multi-symptom packs are fine. Taking a store-brand nighttime liquid on top of extra-strength pain relievers is how people double up without noticing.
Pantry staples: one-word ingredient lists are easy calls
For single-ingredient basics, the ingredient line does the comparing for you. Granulated sugar, baking soda, cornstarch, plain salt: if the list is one word long and the words match, buy the cheaper package. Salt deserves a second glance, since iodized and non-iodized versions sit side by side.
Flour is where a name brand can earn its price, at least for bread. Protein content drives how much gluten forms, and King Arthur guarantees 11.7% protein in its all-purpose flour, near the top for supermarket brands. In Cook’s Country’s rundown of all-purpose flours, Gold Medal came in at 10.5% and Pillsbury at 10% to 11%. Store-brand bags rarely print a percentage, and the nutrition panel only lists protein in whole grams per quarter cup, which is too rough to tell close flours apart.
For cookies, pancakes and weeknight cakes, the store bag is fine, and the savings pile up over a holiday baking season. If you bake chewy loaves or pizza dough and care how they turn out, the guaranteed number on the name-brand bag is the thing you’re paying for.
Taste and texture: the store matters as much as the item
No label lists flavor, so for food you judge by taste, blind testing is the best evidence available. In a 2022 Consumer Reports test of 70 store-brand products from 10 retailers, 76% tasted as good as the name brand, at prices 5% to 72% lower per serving. Kroger’s creamy ranch beat Hidden Valley at about half the price, and Aldi’s condensed chicken noodle soup beat Campbell’s.
The same test doubles as a warning. Whole Foods’ ranch came out thin and sour, Trader Joe’s version barely tasted like ranch, and a few store brands cost more than the name brand beside them, with BJ’s peanut butter running 37% pricier in that comparison. “Store brand” covers a lot of different products. Each chain sources its own version, so a win at one store tells you nothing about the same item at another.
Batteries and cleaners: read the chemistry and the percentage
Batteries
With batteries, chemistry matters more than the logo. In YouTube tester Project Farm’s fan runtime test, Costco’s Kirkland alkaline AAs ran 7 hours 29 minutes against 8 hours 3 minutes for Energizer Max, close enough that Kirkland ranked higher once price was factored in. Consumer Reports’ past ratings also put Kirkland alkalines ahead of Energizer Max. Energizer’s lithium cells beat the alkalines in both sets of results.
So buy store-brand alkalines in the big pack for remotes, wall clocks and kids’ toys, and spend on lithium only for gear you use hard, like a flashlight that lives in the car. Check the date stamped on the pack either way. A cheap pack that sat in a warehouse for years has used up part of its shelf life before you open it.
Bleach and other cleaners
Bleach labels state the sodium hypochlorite percentage, and that number belongs in the price comparison. Household bleach long ran around 5.25% to 6%, some current bottles are 8.25%, and health departments publish separate dilution charts for each strength. A bigger, cheaper jug at a lower percentage can be less of a deal than it looks.
If you’re buying bleach to disinfect rather than whiten laundry, look for an EPA registration number and disinfecting directions on the label. Some thickened, splash-less bottles, name brands included, are labeled for laundry and household cleaning only. A store-brand jug with a registration number and the same percentage does the disinfecting job for less.
The same logic covers fluoride toothpaste and antiperspirant. Both are regulated as over-the-counter drugs and carry their own Drug Facts panels, so compare the active ingredient and its percentage exactly as you would with pain relievers.
Infant formula: same federal rules, one caution
Formula is one of the strongest cases for the store label. The FDA requires every infant formula sold in the US to meet the same federal nutrient requirements, and manufacturers have to notify the agency before marketing a new one. A store-brand formula is held to the same rulebook as the name brand it’s compared to.
The caution is about type rather than brand. Match the base (milk-based, soy, partially hydrolyzed) and the style the label compares itself to, and talk to your pediatrician before switching if your baby is on a specialty or prescribed formula.
Let the store’s guarantee pay for the experiment
The cheapest way to learn whether a store-brand coffee or cereal works for your household is to buy the smallest size and keep the receipt. Several chains back their own labels. Target’s owned brands, including up&up and Good & Gather, come with a full refund within one year with a receipt if you’re not satisfied. Aldi’s Twice as Nice Guarantee replaces an unsatisfactory Aldi-exclusive product and refunds your money, with restrictions the store spells out.
The cases where the name brand still makes sense are narrower than the price gap suggests. You need a spec the store label won’t print, like flour protein. A specific formula agrees with you and the store copy doesn’t. Or a sale plus a coupon makes the name brand cheaper per unit that week, which happens more often than store-brand loyalists admit.
A two-minute check at the shelf
- Compare unit prices in the same unit, and do the division yourself when the tags disagree.
- For medicine, fluoride toothpaste and antiperspirant: same active ingredient, same amount, same form.
- For bleach and disinfectants: same percentage, plus an EPA registration number if you need to disinfect.
- For food judged by taste: smallest size first, receipt in the bag, decision after one try.
- For anything with a spec you rely on, pay for the number printed on the bag.
If you change only one habit this week, start in the medicine aisle. The proof is printed on the back of every box, and the comparison takes less time than reading the front.
