Home › Menu & Prices › Dunkin' Donuts vs Starbucks: Prices, Cup Sizes & Caffeine Compared (2026)

Dunkin’ vs Starbucks comes down to a clear trade-off in 2026: Dunkin’ costs about 20% less on matched drinks, while Starbucks packs more caffeine into a hot brewed cup. A Medium Dunkin’ hot coffee is about $2.69 and a Starbucks Grande Pike Place is about $3.75. This guide compares prices, cup sizes in ounces, caffeine, calories and food for equivalent items, including the places where Starbucks comes out ahead. Prices are typical US prices and vary by location, because Dunkin’ is independently franchised and Starbucks does not publish a national price list.

Dunkin’ vs Starbucks Prices: Drink-by-Drink Comparison (2026)

In the Dunkin’ vs Starbucks prices comparison, Dunkin’ costs less on every matched drink at typical 2026 prices, about 20% less on average. The widest gap is hot brewed coffee, where a Dunkin’ Medium saves about $1.06 (28%), and the narrowest is cold brew at $0.76 (15%). Put the other way, Starbucks charges about 26% more for the closest equivalent.

The table pairs each Dunkin’ Medium with a Starbucks Grande, the nearest standard match, though the cups differ: a hot Medium is 2 ounces smaller than a Grande and an iced Medium is 8 ounces larger. Starbucks figures come from a May 2026 price survey, so treat them as typical rather than exact, and Dunkin’ prices are the typical figures used across our Dunkin’ menu with prices and Dunkin’ drinks menu. Franchise owners and city markets set their own prices, so check each app for your store.

Dunkin’ vs Starbucks Cup Sizes: Medium, Grande and Venti in Ounces

In any Dunkin’ vs Starbucks comparison, the cup names mislead, because a Dunkin’ Medium and a Starbucks Grande are different sizes. A hot Dunkin’ Medium holds 14 ounces and a hot Grande holds 16, but an iced Dunkin’ Medium holds 24 ounces, 8 more than an iced Grande. The cups line up cleanly in only a few places, which is why price per ounce is the fairer test.

Dunkin’ hot sizes run 10, 14, 20 and 24 ounces, and iced sizes run 16, 24 and 32. Starbucks uses Tall at 12 ounces, Grande at 16 and Venti at 20 hot or 24 iced, plus a 30-ounce Trenta for some cold drinks. Our Dunkin’ cup sizes chart lists every Dunkin’ size and which drinks come in each.

Cups That Match by Ounces

Four size pairs hold the same or nearly the same amount, so they make the fairest comparison. A Dunkin’ Small iced drink and a Starbucks Grande are both 16 ounces, a Dunkin’ Large hot drink equals a hot Venti at 20, and a Medium iced drink matches an iced Venti at 24. A Dunkin’ Large iced drink (32 ounces) is close to a Trenta (30).

Dunkin’ vs Starbucks Price per Ounce: Which Chain Gives You More Drink?

Dividing each price by the cup’s fluid ounces removes the size-name confusion, and Starbucks costs more per ounce in all four rows below. The premium runs from 16% on the pumpkin spice latte to 34% on the cold brew. Three of the rows compare cups of exactly the same volume, so those gaps come from price alone, not from a bigger or smaller cup.

The hot coffee row is the exception, because no verified Venti Pike Place price was available, so it pairs a 14-ounce Dunkin’ Medium with a 16-ounce Grande. That setup favors Starbucks, since a Dunkin’ Large at $2.99 works out to 15.0¢ an ounce against 19.2¢ for the Medium, yet Starbucks still charges 22% more. To rerun the math with local prices, use the sizes listed in Dunkin’ hot coffee prices by size, the iced coffee sizes and prices page and the Dunkin’ cold brew guide.

Dunkin’ vs Starbucks Caffeine: Which Coffee Is Stronger?

In the Dunkin’ vs Starbucks caffeine matchup, Starbucks wins the hot brewed cup: a Grande Pike Place has about 310 mg of caffeine, roughly 48% more than the 210 mg in a Dunkin’ Medium hot coffee. The result flips for iced coffee, cold brew and lattes, where Dunkin’s bigger iced cups and its espresso base carry more caffeine per cup. So the answer depends on which drink you order.

Caffeine scales with cup size, so the table below also shows milligrams per ounce and per dollar. Dunkin’ publishes only a 180–330 mg range for its hot coffee sizes and no caffeine figure for lattes, so the Dunkin’ numbers are third-party estimates. The Starbucks numbers are the chain’s own figures as cited by secondary sources, and our Dunkin’ coffee menu and Dunkin’ latte prices break down every Dunkin’ brewed and espresso option.

Caffeine per Dollar

Starbucks gets slightly more caffeine per dollar from hot brewed coffee, about 83 mg against 78 mg for a Dunkin’ Medium. Dunkin’ pulls ahead as soon as you size up or go iced: a Medium iced coffee gives 297 mg for $3.29, nearly the Grande Pike Place’s 310 mg for $0.46 less. The best value on the Dunkin’ menu is a Large iced coffee at about 107 mg per dollar.

How Much Caffeine Is Too Much

The US FDA cites 400 mg a day as an amount not generally linked to negative effects in healthy adults. A Starbucks Grande Pike Place uses about 78% of that and a Dunkin’ Medium hot coffee about 52%. A Dunkin’ Large iced coffee at 396 mg is close to the whole daily guideline in one cup. Anyone who is pregnant, nursing or sensitive to caffeine should ask a doctor what amount is right for them.

Pumpkin Spice Latte: Dunkin’ vs Starbucks in Fall 2026

In the Dunkin’ vs Starbucks pumpkin spice latte matchup, the price gap holds but the nutrition numbers tilt toward Starbucks. A Dunkin’ Medium Pumpkin Spice Signature Latte is about $5.19 with 420 calories and 55 g of sugar, and a Starbucks Grande is about $6.45 with 390 calories and 50 g of sugar. Dunkin’ is 20% cheaper per cup, though its hot Medium holds 2 fewer ounces.

Dunkin’s fall menu launched nationwide on August 19, 2026, and Starbucks brought back its Pumpkin Spice Latte on August 25, 2026. Both are limited-time drinks with no announced end date, and Dunkin’ has launched its holiday menu in the first week of November every year since 2020, so check the app to see whether your store still has it. The builds differ too: Dunkin’ tops its latte with whipped cream, caramel drizzle and cinnamon sugar, while the Starbucks figures are for 2% milk with whipped cream.

Per ounce the Dunkin’ latte is cheaper, but the Starbucks Grande has fewer calories per cup and per ounce and about 5 g less sugar. An unofficial estimate puts a Dunkin’ Medium made with skim milk and no whipped cream or drizzle at roughly 265 calories, the simplest way to close that gap. Our Dunkin’ pumpkin spice latte page and the Dunkin’ fall menu cover sizes, prices and the rest of the fall lineup.

Dunkin’ vs Starbucks Food and Full Orders: What Coffee Plus Breakfast Costs

Pastries carry a bigger Dunkin’ vs Starbucks prices gap than most drinks. A Dunkin’ butter croissant is about $2.74 at the midpoint of its $2.49–$2.99 range, and a Starbucks butter croissant is about $3.75, so Starbucks costs 37% more. A Starbucks blueberry muffin at $3.75 costs 48% more than the Dunkin’ midpoint of $2.54.

Starbucks calories for these pastries were not verified for this page, so the calorie column covers Dunkin’ only. A classic Dunkin’ donut at $1.49–$1.89 costs less than either chain’s croissant, and Starbucks has no direct match for it in our data. See our Dunkin’ croissant guide, the Dunkin’ muffin lineup and the Dunkin’ glazed donut page for Dunkin’ prices and calories.

A Realistic Drink-and-Pastry Order

Pairing a drink with a pastry shows the full Dunkin’ vs Starbucks prices gap. A Medium hot coffee and a butter croissant total about $5.43 at Dunkin’ and about $7.50 at Starbucks, a saving of $2.07. The totals use the Medium and Grande sizes from the first table and the Dunkin’ pastry midpoints.

When Dunkin’ Costs as Much as Starbucks (and When It Doesn’t)

The Dunkin’ vs Starbucks price gap is not guaranteed, because Dunkin’ franchise owners set their own prices. The highest reported price for a Dunkin’ Medium hot coffee ($3.69) is only $0.06 below a typical Starbucks Grande Pike Place ($3.75), so at a high-priced store the hot coffee gap nearly disappears. The pumpkin spice latte is the one drink where the ranges cross: Dunkin’ reaches $5.89, while a 2025 report found a Starbucks Grande selling for $5.75–$7.25 depending on location.

Starbucks does not publish prices either, so its figures are survey values that also move by city. High-cost metro areas push Dunkin’ up as well: one September 2026 survey of those markets listed a Medium hot latte at $5.09–$6.64, which overlaps the typical $5.45 Starbucks Grande. Where the ranges meet, compare both apps before you order.

Delivery Menus Narrow the Dunkin’ vs Starbucks Price Gap

Delivery-app prices run higher than in-store prices at both chains, and the markup narrows the gap. On one price site’s delivery-menu listings from July and August 2026, a Dunkin’ latte was $5.23 against $5.85 at Starbucks, and cold brew was $4.98 against $5.55. Those gaps of $0.62 and $0.57 compare with $0.96 and $0.76 at typical in-store prices, though the listings did not state cup sizes.

Dunkin’ vs Starbucks Rewards and Deals: Where Each Chain Saves You Money

Both chains run an app with a rewards program, so the menu price is not always what you pay. Dunkin’s $6 Meal Deal returned on March 4, 2026 and was still on the menu in October 2026, and Dunkin’ Rewards promos have included $2 for a 10-count MUNCHKINS and a $1 classic donut. Dunkin’ also dropped its non-dairy milk surcharge on March 5, 2025, so oatmilk or almondmilk no longer raises the price of a latte.

Current Starbucks reward rates were not verified for this page, so compare the two apps for the offers live in your area before you order. The Dunkin’ app shows your store’s exact prices and lets you order ahead, and the Dunkin’ coupons and deals page tracks which Dunkin’ offers are running now. Promotions are limited-time and participation varies by store.

Dunkin’ vs Starbucks Pros and Cons: Which Should You Choose?

The right pick in a Dunkin’ vs Starbucks decision depends on what you weigh most: price, caffeine per cup, calories or the size of the cup. Dunkin’ wins on price, iced cup volume and caffeine per dollar, while Starbucks wins on hot brewed caffeine, cold brew strength per ounce and pumpkin spice latte calories. The lists below tie every point to a number from this page.

Taste, roast style, seating and the distance to the nearest store matter as much as the numbers, and none of those can be measured here, so try a plain black coffee at each chain before price alone decides. The decision table at the end of this section matches common goals to a specific order. If cutting calories is the goal, start with the lowest-calorie Dunkin’ drinks and the Dunkin’ calorie chart.

Final Verdict: Dunkin’ vs Starbucks, Which Is the Better Value?

In the Dunkin’ vs Starbucks matchup, Dunkin’ is the better value for most orders: it costs about 20% less on matched drinks, Starbucks charges 16% to 34% more per ounce, and Starbucks pastries cost 37% to 48% more. The one clear exception is hot brewed coffee strength, where a Starbucks Grande has 310 mg against 210 mg in a Dunkin’ Medium and slightly more caffeine per dollar. Browse the Dunkin’ menu with prices to price your own order.

The smartest Dunkin’ buy for caffeine is a bigger or iced cup, since a Large iced coffee gives about 107 mg per dollar against 78 for a Medium hot coffee. The smartest Starbucks buy is the Grande Pike Place when strength matters more than cost. Check both apps first, because franchise pricing and high-cost markets can erase a small gap, and the Dunkin’ seasonal menu page shows which limited-time Dunkin’ drinks are running this season.

Dunkin’ Donuts vs Starbucks: Frequently Asked Questions

These are the questions people ask most about Dunkin’ vs Starbucks, answered with the same numbers used in the tables above. The most common mix-up is cup size, since a Dunkin’ Medium and a Starbucks Grande are not the same volume. Caffeine is the second, because the stronger chain changes depending on whether you order hot or iced.

Dunkin’ figures come from the same typical 2026 US prices and nutrition data used across this site. Starbucks figures come from a May 2026 price survey and secondary sources that cite the chain, so they are typical values rather than official ones. When your local menu differs, the app price at your store is the one to trust.
