Lowest-Calorie Dunkin Drinks: Every Size, Milk and Swirl (2026)

By NutriCalc Hub. Published October 28, 2026. 7 min read.

Low calorie Dunkin drinks are easy to find once you know where the calories come from. Plain coffee, cold brew and espresso are close to zero. Milk adds a little, and sweetened flavor swirls add the most. This guide ranks low calorie Dunkin' drinks by size using Dunkin's official US Nutrition Guide, updated September 21, 2026, and shows how to keep your usual order light.

Dunkin' cup sizes are bigger than many people expect: an iced Medium is 24 fl oz and a hot Medium is 14 fl oz. So every number below names the size. You can check any order in our Dunkin' drink calorie calculator.

What are the lowest calorie drinks at Dunkin'?

The lowest calorie drinks at Dunkin are black coffee, cold brew and Americanos, at 5 to 10 calories in a Medium. Milk drinks such as cappuccinos and macchiatos with skim milk stay at 70.

Here are the lowest calorie drinks at Dunkin' in a Medium, from lightest to heaviest:

Every one of these low calorie Dunkin drinks is 100 calories or less in a Medium. Dunkin' doesn't publish caffeine in its nutrition guide, so we don't list caffeine for any Dunkin' drink.

Which lowest calorie drinks at Dunkin' have the most protein?

Among the lowest calorie drinks at Dunkin, milk-based espresso drinks with skim milk give the most protein. A Medium Latte with skim milk has 9 g for 100 calories, and a Medium Cappuccino or Macchiato with skim milk has 6 g for 70.

Dunkin' flavor shots vs swirls: the biggest calorie difference

The short answer to Dunkin' flavor shots vs swirls: flavor shots are unsweetened, and flavor swirls are sweetened and creamy. That single choice can turn a 5-calorie coffee into a 170-calorie one.

A Medium Caramel Swirl Iced Coffee has 165 more calories and 38 g more sugar than the same coffee black (170 − 5; 38 − 0). That's about 9.5 teaspoons of sugar from the swirl alone (38 ÷ 4).

When people compare Dunkin' flavor shots vs swirls, the practical rule is simple: choose a flavor shot when you want flavor without sugar, and treat a swirl as a dessert-style add-in. Dunkin's guide lists flavor shots as unsweetened, but doesn't publish a calorie figure per shot in our dataset, so we don't give one.

How do Dunkin' flavor shots vs swirls change a latte?

The difference is just as big in a latte. A Medium Latte with skim milk has 100 calories and 14 g of sugar; a Medium Caramel Swirl Iced Latte with skim milk has 260 calories and 52 g of sugar. On Dunkin' flavor shots vs swirls in a latte, the swirl adds 160 calories (260 − 100).

Low calorie Dunkin' iced coffee: every milk and size

A low calorie Dunkin' iced coffee starts at 5 calories black in every size. Skim milk keeps it at 15 to 25 calories, and cream raises it to 60 to 120, depending on the size.

The best low calorie Dunkin iced coffee with milk is skim, at 20 calories in a Medium. Cream and sugar take the same Medium to 190 calories. For every combination, see our full guide to Dunkin' iced coffee calories by size and milk.

Is cold brew a low calorie Dunkin' iced coffee option?

Yes. Black Cold Brew has 5 calories in a Small or Medium, and 30 calories with oat milk in a Medium, the same as a low calorie Dunkin' iced coffee with oat milk. Our comparison of cold brew vs iced coffee explains how the two drinks differ.

Hot coffee follows the same pattern: black is 5 calories and skim milk adds only a little. See Dunkin' hot coffee calories for every size, including the Extra Large.

Low calorie Dunkin' latte: which milk is lightest?

The lowest calorie Dunkin' latte is made with skim or almond milk, at 100 calories in a Medium. Oat milk is 130 and whole milk is 170.

Skim and almond milk tie on calories, but skim gives 9 g of protein against 1 g. Oat milk has the least sugar, 5 g, but more calories. So the best low calorie Dunkin' latte depends on your goal: skim for protein, oat for the least sugar.

A Small skim latte is lighter still, at 70 calories. For every size and milk, see our guide to Dunkin' latte calories. If you want a low calorie Dunkin' latte with flavor, add an unsweetened flavor shot instead of a swirl.

Low sugar Dunkin' drinks

Black coffee, cold brew and Americanos are the low sugar Dunkin' drinks with 0 g of sugar. Among milk drinks, the Medium Shakin' Espresso with Sugar Free Vanilla and Almondmilk has just 3 g, and an oat milk Macchiato has 4 g.

Here are good low sugar Dunkin' drinks in a Medium:

• Iced Coffee, Hot Coffee or Cold Brew (black): 0 g of sugar.

• Americano or Iced Americano: 0 g of sugar, 10 calories.

• Iced Coffee with cream: 1 g of sugar, 90 calories.

• Shakin' Espresso with Sugar Free Vanilla and Almondmilk: 3 g of sugar, 70 calories. See all versions in our Dunkin' Shakin' Espresso calories guide.

• Macchiato with oat milk: 4 g of sugar, 90 calories.

• Latte with oat milk: 5 g of sugar, 130 calories.

Low sugar Dunkin drinks matter because sweetened drinks add up fast, and most of them are also low in calories. A Medium Iced Coffee with sugar has 26 g, and a Medium Iced Chai Latte with skim milk has 41 g. The American Heart Association suggests limiting added sugar to about 36 g a day for most men and 25 g for most women.

Not all sugar on the label is added: milk has natural sugar too. That's why low sugar Dunkin' drinks made with skim milk still show 9 to 14 g of sugar.

How to order low calorie Dunkin' drinks

Start with a black coffee, cold brew or espresso base, then add milk and flavor shots rather than cream and swirls. That keeps most low calorie Dunkin' drinks under 100 calories.

1. Pick a zero-calorie base: Iced Coffee, Hot Coffee, Cold Brew or an Americano.

2. Choose skim or almond milk for the fewest calories, or oat milk for the least sugar; that's how a low calorie Dunkin' latte stays at 100 in a Medium.

3. Use flavor shots, not swirls: shots are unsweetened; swirls are sweetened.

4. Size down: a Small iced coffee is 16 fl oz, the same size as a Starbucks Grande.

5. Skip "with sugar": it takes a Medium black iced coffee from 5 to 110 calories.

The best low calorie Dunkin drinks are black coffee, cold brew and Americanos at 5 to 10 calories, followed by skim milk cappuccinos and macchiatos at 70 and skim or almond lattes at 100 in a Medium. Choose flavor shots over swirls, pick your milk on purpose, and check your exact order in the Dunkin' calculator before you go.
