Some businesses depend on customers making an occasional large purchase. Others sell products that disappear from cupboards, bathrooms and refrigerators and then need to be bought again.

That difference matters. Toothpaste gets used up. Diapers are disposable. Laundry detergent eventually runs out. Snacks are eaten. Beverages are consumed. These products create opportunities for repeat purchases that cars, appliances and many other durable goods cannot match.

The five companies below are not a ranking, and repeat purchasing does not guarantee rising sales. Consumers can switch brands, buy cheaper alternatives, reduce consumption or respond to higher prices. But each company has built substantial operations around products that are consumed or replaced regularly.

Few large companies are as concentrated on everyday household routines as Procter & Gamble.

Its portfolio includes Tide and Ariel laundry products, Pampers diapers, Always feminine-care products, Charmin tissue, Crest toothpaste, Gillette razors, Head & Shoulders shampoo and Dawn dishwashing products. P&G itself describes its portfolio as being focused on categories where product performance matters to consumers, spanning fabric care, home care, baby care, feminine care, family care, hair care, skin and personal care, oral care, personal health care and grooming.

Those categories generated $87.0 billion in net sales in P&G's fiscal year ended June 30, 2026, up 3% from the previous year. Fabric and Home Care accounted for 35% of net sales, while Baby, Feminine and Family Care contributed another 24%. Together, those two groups represented roughly 59% of company net sales.

The important feature is not simply the size of those businesses. It is what happens after the sale. A bottle of detergent or package of diapers does not remain in use for years. It is gradually consumed and replaced.

That does not prevent demand from moving around. P&G reported that total company volume was roughly flat in fiscal 2026, while individual categories showed differing trends. Still, nine of its 10 product categories held or increased organic sales during the year. P&G's organic sales measure is a non-GAAP measure intended to show underlying sales performance after excluding certain effects that can obscure comparisons with the previous period.

The result is a business whose customers may encounter its products repeatedly throughout a normal week, from brushing their teeth and washing clothes to shaving and cleaning their homes.

A bottle or can of Coca-Cola is about as far from a durable product as a company can get. Once it is consumed, another sale is required to replace it.

That simple characteristic operates at enormous scale.

The Coca-Cola system sold 33.8 billion unit cases in 2025, compared with 33.7 billion in 2024. Coca-Cola defines a unit case as 192 U.S. fluid ounces of finished beverage, equivalent to 24 eight-ounce servings, with limited exceptions for some Costa products. Unit case volume includes products sold directly or indirectly by Coca-Cola and its bottling partners, so it is a measure of beverage volume across the broader Coca-Cola system rather than the company's reported revenue.

That distinction is important because Coca-Cola's $47.9 billion of net revenue in 2025 cannot be compared directly with the retail value of all beverages sold by its bottling system. Coca-Cola earns revenue through a mix of concentrate, syrup and finished-product operations, while independent bottlers account for a large part of the system that ultimately delivers drinks to customers.

More recent results continued to show substantial consumption. In the second quarter of 2026, global unit case volume increased 5% from the comparable quarter, calculated using average daily sales. Trademark Coca-Cola volume increased 5%, while water, sports, coffee and tea increased 6%.

Beverages are not necessities in the same way as some hygiene products, and individual brands still compete intensely for consumer spending. But Coca-Cola benefits from a fundamental feature of the category. Every drink represents a consumption occasion that ends quickly, creating the possibility of another purchase soon afterward.

PepsiCo extends that repeat-purchase model across both beverages and food.

Its portfolio includes Lay's, Doritos, Cheetos, Quaker, Gatorade, Pepsi-Cola and Mountain Dew. In 2025, 58% of PepsiCo's net revenue came from food and 42% from beverages, giving the company exposure to two large categories characterized by frequent consumption. Total net revenue reached $93.9 billion that year.

PepsiCo says its products are consumed more than one billion times a day across more than 200 countries and territories. That figure is a company description of consumption occasions, not a count of individual customers or retail transactions, but it illustrates the frequency associated with the portfolio.

The pattern remained visible in 2026. For the 12 weeks ended June 13, PepsiCo reported $24.18 billion in net revenue, up 6.4% from the comparable period. Its non-GAAP organic revenue measure increased 2.4%. The company said organic growth reflected both pricing and a contribution from organic volume growth.

PepsiCo's model also shows why repeat purchases should not be confused with automatic growth. Consumers can adjust how often they buy snacks, change package sizes or trade among brands as prices and household budgets change. North American performance has not always moved in the same direction as international markets.

Still, a bag of chips and a bottle of sports drink share one commercially useful trait. Neither lasts very long after it reaches the consumer. PepsiCo must keep winning new purchase occasions, but it operates in categories that continually create them.

Toothpaste offers perhaps the clearest example of a product that naturally generates replacement demand.

Colgate-Palmolive reported that Oral Care accounted for 44% of its worldwide net sales during the first six months of 2026. Personal Care contributed 17%, Home Care 17% and Pet Nutrition 22%. These percentages describe the composition of company net sales rather than the size of the broader markets in which Colgate operates.

The company's scale in toothpaste is especially notable. Colgate reported a 41.3% share of the global toothpaste market on a year-to-date basis in its second-quarter 2026 results, while its share of manual toothbrushes was 32.7%.

Those market-share figures need some qualification. Colgate calculates share primarily using consumption and market-share data supplied by third-party vendors, mainly Nielsen, together with internal estimates. The measure represents Colgate's percentage of the dollar value of category sales in countries where it competes and buys market data. Some channels, including certain e-commerce businesses, club retailers and discounters, are not fully covered, and the data normally trails the reporting period by one or two months.

Colgate-Palmolive's worldwide net sales reached $10.69 billion during the first six months of 2026, up 6.6% from the comparable period. The company reported 1.0% volume growth, 1.9% higher net selling prices and a 3.8% positive foreign-exchange effect. These components show why revenue growth should not be treated as a direct measure of how many additional products consumers bought.

What makes Colgate distinctive is the regularity of the underlying need. Toothpaste, soap, surface cleaners and pet food all eventually run out. Maintaining brand preference in those categories can therefore place a company in front of the same household repeatedly.

Kimberly-Clark operates in categories where repeat purchases are often built into the product itself.

Its portfolio includes Huggies diapers, Kleenex tissues, Scott and Cottonelle bathroom tissue, Kotex feminine-care products, and Depend and Poise adult-care products. In its 2025 annual filing, Kimberly-Clark described its business as operating across five global daily-need categories including Baby and Child Care, Adult Care, Feminine Care, Family Care and Professional products.

Kimberly-Clark generated $16.45 billion in net sales from continuing operations in 2025. Baby and Child Care was its largest principal product category at $6.77 billion, followed by Family Care at $4.06 billion. Adult Care generated $1.95 billion and Feminine Care $1.71 billion. These are company sales figures, not estimates of the total retail markets for those categories.

The company's latest results also demonstrate that a repeat-purchase business can still experience modest overall growth. Second-quarter 2026 net sales were $4.2 billion, up 0.6%, while the company said organic sales were broadly in line with the prior-year quarter. International Personal Care sales increased 4.0%, supported by currency movements and a 1.0% rise in organic sales.

Kimberly-Clark is also in the middle of a major corporate change. Its acquisition of consumer-health company Kenvue remained pending in the latest available company disclosures, with closing expected in the fourth quarter of 2026 subject to remaining regulatory approvals and other conditions. The historical sales figures discussed here therefore describe Kimberly-Clark before the proposed combination rather than the future combined company.

These five companies operate in different corners of consumer spending, but the economics of their products share an important feature.

The products are repeatedly consumed, depleted or discarded.

That gives the companies more frequent opportunities to sell to existing households than businesses that depend primarily on infrequent purchases of durable goods. A consumer may buy a refrigerator once in many years, while toothpaste, detergent, tissues, diapers, drinks and snacks can require replenishment again and again.

But recurring need belongs to the product category, not automatically to a particular brand. Consumers can switch from Tide to another detergent, Coca-Cola to another drink or Colgate to another toothpaste. Retailers can promote private-label alternatives. Higher prices can reduce volume. Demographics can change demand for products such as diapers, and health trends can reshape food and beverage preferences.

That is why the strongest evidence of repeat-purchase economics is not simply revenue growth in a single year. It is the combination of frequently replenished categories, large established brands, wide distribution and sustained consumer demand.

P&G, Coca-Cola, PepsiCo, Colgate-Palmolive and Kimberly-Clark have built enormous businesses around that combination. Their challenge is not creating another reason for consumers to eventually replace a durable product. It is persuading them to choose the same brand the next time an everyday product runs out.
