Dunkin' Caffeine & Calories Guide by Drink (2026)
Quick Answer
A medium Dunkin' Iced Coffee has about 294mg of caffeine and only ~5 calories black, while a medium Frozen Coffee is the calorie king at 530. Here is the full Dunkin' caffeine and calorie breakdown by drink, ranked.
QUICK ANSWER
A medium Dunkin' Iced Coffee has about 294mg of caffeine, a Cold Brew about 260mg, and a Frozen Coffee about 295mg— the strongest drinks on the core menu. Espresso drinks are milder: a medium Latte is about 166mg. On calories, black coffee is nearly free at ~5 calories, a medium Latte is ~170, and the medium Frozen Coffee tops out at ~530. Dunkin publishes one medium caffeine figure per drink, so per-size caffeine is an estimate. The FDA cites 400mg per day as a safe ceiling for healthy adults.
“How much caffeine is in Dunkin'?” and “how many calories?” have very different answers depending on whether you order a plain iced coffee or a blended Frozen Coffee. The two numbers do not move together: the leanest drinks on the menu are also among the strongest, while the richest drinks are only middling on caffeine. This guide gives you both figures for every core Dunkin' drink, ranks the strongest and the lowest-calorie orders, and flags exactly where Dunkin's official numbers are precise and where they are estimates.
Key Takeaways
- A medium Iced Coffee (~294mg) and Frozen Coffee (~295mg) are the most caffeinated core drinks; Cold Brew is ~260mg.
- Black coffee is ~5 calories — hot Original Blend, Iced Coffee, and Cold Brew are all nearly calorie-free before milk or sugar.
- The medium Frozen Coffee is the calorie king at ~530; a large Signature Latte is ~440; a plain medium Latte is ~170.
- Dunkin publishes only a single medium caffeine figure per drink, so small/large caffeine numbers are estimates that scale with ounces.
- The FDA cites 400mg/day as a safe ceiling for healthy adults — about one medium Iced Coffee plus a Cold Brew.
How much caffeine is in Dunkin' coffee by drink?
Iced and brewed coffee carry the most caffeine at Dunkin'; espresso drinks are roughly half. The single biggest driver is whether the drink is brewed or iced coffee or an espresso beverage. Iced and cold brew steep a large amount of coffee, so a medium reaches 260–294mg, while a Latte built from measured shots lands near 166mg. The table below lists the official medium (default) caffeine figure Dunkin publishes for each core drink. Because Dunkin only exposes the medium value, treat small and large as scaling roughly with the ounces.
| Drink | Type | Caffeine (Medium) |
|---|---|---|
| Frozen Coffee | Frozen | ~295mg |
| Iced Coffee | Iced brewed | ~294mg |
| French Vanilla Iced Coffee | Iced brewed | ~294mg |
| Americano | Espresso | ~284mg |
| Caramel Iced Macchiato | Iced espresso | ~284mg |
| Cold Brew | Cold brew | ~260mg |
| Original Blend Hot Coffee | Brewed | ~210mg |
| Latte | Espresso | ~166mg |
| Cappuccino | Espresso | ~166mg |
| Iced Latte | Iced espresso | ~166mg |
Treat every number as a careful estimate. Dunkin notes that caffeine varies with the brewing method and the specific location, which is why we publish the official medium figure rather than false per-size precision. To order any of these, the Dunkin' store locator finds a nearby shop, and our Dunkin' hours guide covers when they open and close.
Which Dunkin' drink has the most caffeine?
A medium Frozen Coffee (~295mg) and Iced Coffee (~294mg) are the most caffeinated core drinks, followed by the Americano and Caramel Iced Macchiato (~284mg) and Cold Brew (~260mg). Iced and brewed coffee dominate because they steep far more coffee per serving than an espresso drink. The ranking below compares core drinks at the medium size, strongest to weakest, so you can pick your buzz level at a glance. Sizing up to a large pushes these figures higher.
| Rank | Drink (Medium) | Caffeine |
|---|---|---|
| 1 | Frozen Coffee | ~295mg |
| 2 | Iced Coffee / French Vanilla Iced | ~294mg |
| 3 | Americano / Caramel Iced Macchiato | ~284mg |
| 4 | Cold Brew | ~260mg |
| 5 | Original Blend Hot Coffee | ~210mg |
| 6 | Latte / Cappuccino / Iced Latte | ~166mg |
Note that Dunkin does not publish a caffeine figure for the Signature Latte, so it is left off the ranking; as an espresso drink, expect it near the standard Latte at about 166mg. For a cross-brand comparison, our Starbucks caffeine chart shows how these numbers stack up against the other big chain, and the caffeine hub ranks the strongest drinks across every brand we cover.
How many calories are in Dunkin' coffee drinks?
Black coffee is about 5 calories; milk-and-sugar drinks climb from ~120 to over 500. This is where the numbers flip: the most caffeinated drinks (black iced coffee, cold brew) are also the leanest, while blended and sweetened drinks pile on calories from milk, swirls, and sweet bases. Unlike caffeine, Dunkin publishes calories per size, so the table below lists small, medium, and large for the core lineup.
| Drink | Small | Medium | Large |
|---|---|---|---|
| Original Blend Hot Coffee (black) | 5 | 5 | 5 |
| Iced Coffee (black) | 5 | 5 | 5 |
| Cold Brew (black) | 5 | 5 | 5 |
| Americano | 5 | 10 | 10 |
| Cappuccino | 80 | 120 | 160 |
| Caramel Iced Macchiato | — | 90 | — |
| French Vanilla Iced Coffee | 110 | 170 | 220 |
| Latte | 120 | 170 | 230 |
| Iced Latte | 120 | 170 | 230 |
| Signature Latte | 250 | 340 | 440 |
| Frozen Coffee | — | 530 | — |
A dash means Dunkin does not publish that size, usually because the live product page and the nutrition PDF conflict on the figure. Milk-based drinks here use the whole-milk standard formulation; choosing skim milk lowers them. For prices on all of these, see our Dunkin' menu prices 2026 guide, and the calories hub compares low-calorie orders across every chain.
What are the lowest-calorie drinks at Dunkin'?
Black hot coffee, black Iced Coffee, and Cold Brew are the lowest-calorie drinks at Dunkin', each about 5 calories, followed by the Americano at 5 to 10. The calories in a Dunkin' coffee come almost entirely from what you add, not the coffee itself. That makes the drink easy to tailor: order it black or with a splash of skim milk and an unsweetened flavor shot to stay under about 30 calories while keeping the flavor.
- ~5 cal: black Original Blend, black Iced Coffee, black Cold Brew.
- 5–10 cal: Americano (espresso and hot water).
- Swap to cut calories: unsweetened flavor shot instead of a sweetened swirl; skim milk instead of whole; skip the whipped cream on Signature drinks.
- Watch out: Frozen Coffee (~530), Signature Latte (up to ~440 large), and full-sugar swirls add the most.
The key difference from a Latte is the milk: a medium Latte is about 170 calories, while black iced coffee with the same caffeine range is a fraction of that. If you want the caffeine without the calories, iced coffee and cold brew are the clear winners.
How much caffeine is in Dunkin' Cold Brew vs Iced Coffee?
A medium Dunkin' Iced Coffee is about 294mg and a medium Cold Brew about 260mg — both higher than any espresso drink on the menu. The two taste different despite similar strength. Iced Coffee is brewed hot at double strength and flash-chilled over ice, giving a brighter, more traditional coffee flavor. Cold Brew is steeped in cool water for many hours, producing a smoother, lower-acidity cup. Both are served black at about 5 calories, so the choice comes down to taste rather than caffeine or calories.
Because Dunkin only lists a medium value, a small of either is lower and a large higher, scaling with the ounces of coffee. If you are deciding between the two brewing styles across chains, our cold brew vs iced coffee guide breaks down the difference in detail.
How much Dunkin' caffeine is safe per day?
The FDA cites 400mg of caffeine per day as an amount not generally associated with negative effects for healthy adults. In Dunkin' terms, that is roughly one medium Iced Coffee (~294mg) plus a small coffee, or a single medium Cold Brew with room to spare. Because a large Iced Coffee can approach the ceiling on its own, iced-coffee drinkers should keep an eye on their total, especially if they order more than one a day.
Tolerance varies. Pregnant people, teens, and anyone sensitive to caffeine should aim well below 400mg and consult a doctor; the FDA’s guidance on caffeine notes that effects like jitteriness and a fast heartbeat appear at different doses for different people. Dunkin publishes per-drink caffeine and full nutrition on its official Dunkin' nutrition pages, which are authoritative if you need an exact figure for a specific or customized order.
Frequently asked questions
How much caffeine is in a medium Dunkin' Iced Coffee?+
A medium (24 oz) Dunkin' Iced Coffee has about 294mg of caffeine, which makes it one of the strongest standard drinks on the menu. Iced coffee is brewed double-strength and served over a large volume of ice, so it carries more caffeine than most espresso drinks. A medium hot Original Blend, by contrast, is about 210mg in a smaller 14 oz cup. If you want the exact figure for your size, Dunkin publishes a medium value on each product page and notes it varies by brewing method and location.
Which Dunkin' drink has the most caffeine?+
Among core menu drinks, the medium Frozen Coffee (~295mg) and medium Iced Coffee (~294mg) top the list, followed closely by the French Vanilla Iced Coffee (~294mg), Americano and Caramel Iced Macchiato (~284mg each), and Cold Brew (~260mg). Brewed and iced coffee generally beat espresso drinks because they steep far more coffee per serving. A medium Latte or Cappuccino sits much lower at about 166mg. If maximum caffeine is the goal, a large Iced Coffee or Cold Brew will push even higher than the medium figures shown here.
How many calories are in Dunkin' black coffee?+
Dunkin' black coffee is nearly calorie-free. A hot Original Blend, an Iced Coffee, and a Cold Brew are all about 5 calories in any size before you add anything. The calories arrive with cream, whole milk, flavor swirls, and sugar, which can add 100 to 300 calories depending on the order. An Americano is similarly light at roughly 5 to 10 calories. If you are watching calories, ordering coffee black or with a splash of skim milk and an unsweetened flavor shot keeps the drink under about 30 calories.
How many calories are in a Dunkin' Frozen Coffee?+
A medium (24 oz) Dunkin' Frozen Coffee has about 530 calories, making it the highest-calorie coffee drink on the core menu. It is blended with milk, coffee, and a sweet base, so it drinks more like a milkshake than a brewed coffee. It also carries a high caffeine load of about 295mg. Sizing down, cutting the sweetener, or asking for skim milk reduces the calories, but a Frozen Coffee will always land well above a plain iced coffee. Treat it as an occasional treat rather than a daily driver.
What is the lowest-calorie drink at Dunkin'?+
The lowest-calorie Dunkin' drinks are black hot coffee, black Iced Coffee, and Cold Brew, each about 5 calories, along with a plain Americano at 5 to 10 calories. Adding an unsweetened flavor shot (rather than a sweetened swirl) keeps the drink essentially calorie-free while adding flavor. Skim milk adds only a few calories, whereas whole milk, cream, and swirls add the most. For a genuinely low-calorie order, ask for iced coffee with skim milk and an unsweetened shot of vanilla.
How much caffeine is in Dunkin' Cold Brew?+
A medium (24 oz) Dunkin' Cold Brew has about 260mg of caffeine. Cold brew is steeped slowly in cool water for an extended time, which produces a smooth, high-caffeine concentrate. It sits just below Iced Coffee (~294mg) but above most espresso drinks like the Latte (~166mg). Because Dunkin only lists a medium value, a small cold brew is somewhat lower and a large somewhat higher, scaling roughly with the ounces of coffee. It is one of the strongest ways to get your caffeine at Dunkin'.
Does a Dunkin' Latte have less caffeine than iced coffee?+
Yes. A medium Dunkin' Latte or Cappuccino has about 166mg of caffeine, roughly half the ~294mg in a medium Iced Coffee. Espresso drinks are built from a measured shot or two, while iced and brewed coffee steep a much larger bed of grounds. The trade-off is calories: a medium Latte is about 170 calories from the milk, versus about 5 for black iced coffee. So a Latte is the milder, creamier option, and iced coffee is the stronger, leaner one.
Why does Dunkin' only show one caffeine number per drink?+
Dunkin' publishes a single medium (default) caffeine figure on each product page and notes that the amount is approximate and varies by brewing method and location. The product pages do not break caffeine out by small and large, so any per-size caffeine numbers you see elsewhere are estimates that scale with the ounces of coffee. We show the official medium value and label it clearly. For calories, Dunkin does publish per-size figures, which is why the calorie tables in this guide list small, medium, and large.
How much Dunkin' caffeine is safe in a day?+
The U.S. Food and Drug Administration cites 400mg of caffeine per day as an amount not generally associated with negative effects for healthy adults. At Dunkin' that is roughly one medium Iced Coffee (~294mg) plus a small coffee, or a single medium Cold Brew with room to spare. Pregnant people, teens, and anyone sensitive to caffeine should aim well below 400mg and consult a doctor. Because a large Iced Coffee can approach the ceiling on its own, it pays to track your total across the day.
Are Dunkin' Signature Lattes high in calories?+
Yes. A Dunkin' Signature Latte is one of the higher-calorie drinks on the menu, running about 250 calories for a small, 340 for a medium, and 440 for a large, because it adds whipped cream, drizzle, and sweet flavor on top of the milk and espresso. A plain Latte, by comparison, is about 170 calories in a medium. Dunkin does not publish a caffeine figure for the Signature Latte, but it is espresso-based, so expect it to be in the same range as a standard Latte (~166mg medium).
Bottom line:a medium Dunkin' Iced Coffee is about 294mg of caffeine and only ~5 calories black, a medium Cold Brew about 260mg, and a medium Latte about 166mg with ~170 calories. The Frozen Coffee is the calorie king at ~530, and the leanest, strongest pick is a black iced coffee or cold brew. Keep your daily caffeine under the FDA’s 400mg guideline and use the tables above to match the buzz and the calories to what you want.
