Dunkin' Peaks at 9 A.M. Starbucks Peaks at Noon. What Does That Say About Their Customers?

Dunkin' is busiest at 9 a.m. Starbucks is busiest at noon. That is the clearest difference between the two coffee chains in phone-location estimates for the year through July 2026.

Much else lines up with it. Dunkin' gets more of its visits on weekdays, its visits are shorter, and its card customers buy more often and spend less each time. Starbucks gets a larger share of its visits at the weekend and more of them after 5 p.m. The pattern fits a familiar split: Dunkin' as the cheaper weekday coffee on the way to work, Starbucks as more of a treat people make time for at the weekend. The data fit that pattern. They cannot show why people choose one or the other.

The two chains draw overlapping crowds. A third of Dunkin's card customers also buy at Starbucks in the same month, and the demographic profiles of their spending are close. Spending comparisons need care, because Starbucks customers pay a large share through prepaid cards and the Starbucks app.

When they go

Among 1,720 chains with at least 100 locations in the data, Dunkin' ranks in the top 4% for how much of its traffic falls in the early morning: 31.8% of its visits come between 5 and 10 a.m. Starbucks, at 19.8%, sits almost exactly at the median chain's 19.4%. Starbucks draws more of its visits later in the day: 23.7% come after 5 p.m., against 17.5% at Dunkin'.

Only 59 chains lean harder into the morning than Dunkin'. Tim Hortons is one of them, at 36.0%. Starbucks sits in the middle of the pack, next to Chick-fil-A and Panera.

Starbucks leans more on the weekend. Of its visits, 31.4% fall on a Saturday or Sunday, against 29.9% at Dunkin'. Saturday is the busiest day for both, bringing 17.0% of Starbucks visits and 15.9% of Dunkin's. Starbucks has the higher Saturday share in all 42 states where both chains have at least five stores, and the higher weekend share in 40 of them. Dunkin' gets 70.1% of its visits from Monday to Friday, against 68.6% at Starbucks.

That fits Dunkin' as the cheaper weekday routine, a coffee before work, and Starbucks as more of a weekend treat. The gap is small, and visit timing alone can't show why people go. The lower Dunkin' transaction and its more frequent purchases, further down, point the same way.

Dunkin' visits are also shorter. Of its visits, 87% last under five minutes, against 77% at Starbucks and 74% at all U.S. places. Only 5.3% of Dunkin' visits last 21 minutes or more, about half the Starbucks share of 10.0%. The gap holds within 41 of 42 states. Very short visits include drive-through stops and people passing by, so the comparison between the chains is more reliable than the levels.

How often they buy and what they spend

In store-level card data, a Dunkin' customer made 2.21 card purchases a month at the same store, against 1.67 at Starbucks. The average Dunkin' transaction was smaller, $9.22 against $12.47. Monthly card spending per customer ends up nearly equal: $20.35 at Dunkin' and $20.78 at Starbucks. An average transaction is not the price of a coffee, and card purchases do not count every café visit.

Regulars make the difference. At Dunkin', 9% of customers buy five or more times a month at one store, against 5% at Starbucks.

The gap is not a Northeast effect. Dunkin' customers made more card purchases in 38 of 42 states. Matched state by state, they make 1.33 times as many monthly purchases as Starbucks customers, about the same as the national ratio of 1.32. California is the clearest exception. Dunkin's average transaction is lower in 41 of the 42 states, at about 79% of the Starbucks figure. Hawaii is the exception.

How Starbucks customers pay

Starbucks card data need careful reading. Over the latest year, cardholders in ConsumerEdge's panel paid $748 million into Starbucks cards and apps, more than the $682 million recorded as direct café purchases. About 2.2 million panel cardholders made a reload. A reload is a payment to Starbucks, not a café visit, and purchases made later from that balance do not appear as new charges on a bank card.

Direct café card purchases alone make the two chains look alike. A Dunkin' cardholder made 11.0 purchases in the year at $10.56 each, $116 in all. A Starbucks café cardholder made 8.7 at $13.21, $115 in all. That comparison leaves out a major Starbucks payment channel, so it cannot show that the typical customer spends the same total at each.

Reloads also change the trend. Counting café purchases plus reloads, Dunkin' takes about 0.13% of tracked card spending and Starbucks about 0.47%, and Dunkin's spending has stayed at about 0.28 times Starbucks' every year since 2021. Counting café purchases alone, Dunkin' appears to gain ground, from 0.56 of Starbucks in 2022 to 0.60 in 2026. That is because reloads grew from 49% to 53% of Starbucks card spending over the period.

Traffic and seasons

An average Starbucks is about twice as busy as an average Dunkin'. It receives an estimated 3,360 visits a week, against 1,600 at Dunkin'. Starbucks also has more stores in the data, 17,360 against 9,550. Both sit well below McDonald's (4,720) and Chick-fil-A (6,260).

Dunkin's stores are concentrated in the Northeast, so the chains were also compared inside each state. The gap barely moves: a Dunkin' gets 55% of a Starbucks' weekly visits in the same state, against 48% nationally. Starbucks is busier in 41 of 42 states. Hawaii is the only state where an average Dunkin' is busier.

Store traffic has grown faster at Starbucks. Over the last 12 months, visits per store rose 2.8% from a year earlier at Starbucks and 0.7% at Dunkin'. In July 2026, same-store traffic was up 4.4% at Starbucks and 1.8% at Dunkin'. Card spending grew at about the same pace at both, 1.9% in the latest year.

Both chains have an autumn high in card spending. Starbucks peaks in September, 9% above its average month, and stays high through November. January is its low, 8% below average. Dunkin' is flatter. It peaks in October, 6% above average, and December is its weakest month, 7% below. Tim Hortons, the outlying gray line, peaks in summer in this U.S. panel.

Where the stores are

About 53% of Dunkin' stores in the data are in the nine Northeast states, against 13% of Starbucks stores. Dunkin' has more stores than Starbucks in all nine, plus Delaware and Maryland, and fewer everywhere else. Seven states in the data (Alaska, Idaho, Montana, North Dakota, Oregon, South Dakota and Washington) have no Dunkin' at all.

Customers cross between the chains. In July 2025, 32% of Dunkin's 2.1 million panel card customers also bought at Starbucks that month, and 23% of Starbucks' 1.7 million bought at Dunkin'. Across the year the shares ranged from 30% to 34% one way and from 21% to 24% the other. Each chain is the other's top coffee rival in these lists, and McDonald's, Walmart and Target head both. The lists are truncated to each store's top brands, so these are minimum overlaps.

When a rival opens next door

When a new Starbucks opened within a kilometre of a Dunkin', Dunkin's visits didn't measurably change over the next year, across 224 openings. Starbucks shrugged off new Dunkin' and Dutch Bros stores too. The rival it did notice was 7 Brew, the drive-thru chain: about 3% fewer visits nearby, though part of that dip may have started earlier.

Who goes

The customer divide is smaller than the difference in schedules. The two chains' spending profiles move together, with a correlation of 0.89 across 28 demographic groups in every year since 2022. Households earning more than $150,000 account for 33% of Starbucks' tracked spending and 29% of Dunkin's. Starbucks takes a little more from people under 35 (32% against 30%), and Dunkin' more from people over 55 (25% against 22%). These are shares of spending, not counts of customers.

Where visitors live points the same way. Starbucks visitors come from neighborhoods with more high earners: 11.9% of residents are in the top income bands, against 9.9% for Dunkin'. That gap survives within counties. Among visitors living in the same county, Starbucks' neighborhoods are richer in 63% of 2,215 counties.

Other national gaps do not survive. Dunkin' visitors' neighborhoods have more residents flagged Republican, 14.1% against 10.9%, and Starbucks' have more millennials and more people living in multi-family housing. Inside the same county, each of these comes close to an even split, between 49% and 53%. They follow where the stores are more than who each chain draws locally.

Phones seen at the two chains differ more. Of devices seen at Dunkin', 35% are iPhones, against 47% at Starbucks and 55% across all U.S. places. Starbucks ranks above three-quarters of chains; Dunkin' is in the lower 40%. Dunkin's iPhone share is lower in 39 of 42 states, at about three-quarters of the Starbucks share state for state.

The data leave room for both chains in the same person's week. What separates them most clearly is timing: Dunkin's weekday mornings and Starbucks' longer day and busier weekends.
