Dunkin Latte Calories: Hot and Iced, Every Milk and Size
Dunkin latte calories come down to two choices: the milk and the size. A latte is espresso plus a lot of milk, so the milk you pick decides most of what's in your cup, including the sugar and the protein.
Below are the official numbers from Dunkin's US Nutrition Guide (updated September 21, 2026) for hot and iced lattes with every milk, plus flavored swirl lattes and the easiest ways to order lighter. To build any other drink, use our Dunkin drink calorie calculator.
How many calories are in a Dunkin' latte?
A plain Dunkin' latte has 70 to 230 calories, depending on the milk and size. Whole milk is the highest at every size; skim milk is the lowest.
Latte (hot or iced) | Small | Medium | Large |
Whole milk | 120 cal · 9 g sugar · 6 g protein | 170 cal · 13 g sugar · 9 g protein | 230 cal · 18 g sugar · 12 g protein |
Skim milk | 70 cal · 9 g sugar · 6 g protein | 100 cal · 14 g sugar · 9 g protein | 130 cal · 18 g sugar · 12 g protein |
Oat milk | 90 cal · 4 g sugar · 1 g protein | 130 cal · 5 g sugar · 2 g protein | 180 cal · 7 g sugar · 3 g protein |
Almond milk | Not listed | 100 cal · 15 g sugar · 1 g protein | 130 cal · 20 g sugar · 2 g protein |
Source: Dunkin' US Nutrition Guide, updated 2026-09-21. Plain lattes, no swirl. Standard recipes; hand-made drinks can vary. Almond milk is not listed for the Small size.
Are hot and iced Dunkin' lattes the same?
Yes. Dunkin's guide lists the same calories, sugar and protein for a hot latte and an iced latte with the same milk and size name. A medium whole milk latte is 170 calories either way.
The cups are different, though. Hot cups are 10, 14 and 20 fl oz (Small, Medium, Large), while iced cups are 16, 24 and 32 fl oz, because part of every iced cup is ice. We cover the iced cup sizes in more detail in our Dunkin iced coffee calories chart.
Which milk makes the lowest-calorie Dunkin' latte?
Skim milk makes the lowest-calorie latte: 70 calories in a Small, 100 in a Medium and 130 in a Large. Almond milk matches skim in a Medium (100) and Large (130).
• Skim milk: 70, 100 and 130 calories. The lightest choice, with the same protein as whole milk.
• Almond milk: 100 and 130 calories (Medium, Large), but the most sugar of any plain latte: 15 g and 20 g.
• Oat milk: 90, 130 and 180 calories, with the least sugar: 4, 5 and 7 g.
• Whole milk: 120, 170 and 230 calories. The creamiest and the highest in calories.
Switching from whole to skim in a medium saves 70 calories (170 to 100) without losing any protein. For a wider look at how milk changes coffee drinks, see Starbucks milk options and calories.
Which Dunkin latte has the least sugar?
An oat milk latte has the least sugar: 4 g in a Small, 5 g in a Medium and 7 g in a Large. That's less than a third of the sugar in the same size with almond milk.
Plain dairy lattes still contain sugar because milk has natural sugar (lactose): a medium has 13 g with whole milk and 14 g with skim. None of these plain lattes contain a sweetening swirl.
Which Dunkin' latte has the most protein?
Whole and skim milk lattes have the most protein: 6 g in a Small, 9 g in a Medium and 12 g in a Large. Oat and almond milk lattes have only 1 to 3 g.
If protein matters to you, skim is the efficient pick: a medium gives you 9 g of protein for 100 calories, versus 9 g for 170 calories with whole milk. Our guide to how much protein you need a day shows where a latte fits.
How many calories do flavored swirl lattes add?
A lot more than milk does. A medium Caramel Swirl Iced Latte with whole milk has 340 calories and 52 g of sugar, double the calories of a plain medium iced latte with whole milk (170 calories, 13 g sugar).
Medium iced latte | Whole milk | Skim milk |
Plain (no swirl) | 170 cal · 13 g sugar | 100 cal · 14 g sugar |
Caramel Swirl | 340 cal · 52 g sugar | 260 cal · 52 g sugar |
French Vanilla Swirl | 330 cal · 50 g sugar | 260 cal · 50 g sugar |
Source: Dunkin' US Nutrition Guide, updated 2026-09-21. Medium iced lattes. Standard recipes; hand-made drinks can vary.
The swirl adds 170 calories and 39 g of sugar to a medium whole milk iced latte, which is about 10 teaspoons of sugar. Flavor shots are unsweetened, so asking for a shot instead of a swirl keeps the flavor without that sugar.
Latte, cappuccino or macchiato: which is lightest at Dunkin'?
A cappuccino or macchiato is lighter than a latte of the same size and milk. With whole milk, a medium latte has 170 calories, while a medium cappuccino or macchiato has 120.
• Medium, whole milk: latte 170, cappuccino 120, macchiato 120 calories.
• Medium, skim milk: latte 100, cappuccino 70, macchiato 70 calories.
• Medium, oat milk: latte 130, macchiato 90 calories.
A cappuccino has more foam and less liquid milk, which is why it comes in lower. If you like a latte's texture, size and milk are still the bigger levers.
How do I order a lighter Dunkin latte?
Choose skim or almond milk, skip the swirl, and size down if you need to. Those three changes cover almost all the difference between the lightest and heaviest latte.
1. Switch to skim milk. A medium drops from 170 calories to 100.
2. Pick oat milk for less sugar. A medium oat milk latte has 5 g of sugar.
3. Use a flavor shot, not a swirl. You keep the flavor and skip the 39 g of added sweetness in a medium caramel swirl.
4. Size down. With whole milk, a Large is 230 calories, a Medium 170 and a Small 120.
5. Try a cappuccino. A medium whole milk cappuccino is 50 calories lighter than a latte.
