Quick Answer
In a Starbucks vs Dunkin calories comparison, the two chains are closer than most people expect. Black coffee is about 5 calories at both. For a medium latte, Dunkin is slightly lower (about 190 calories) than a Starbucks Grande (about 190–210 calories). Dunkin’s flavored and frozen drinks often carry more sugar, while Starbucks Frappuccinos run higher in calories. The winner depends entirely on the drink — plain coffee is a tie, but customizations decide the rest.
Choosing between two coffee giants often comes down to taste, but if you are watching your intake, the Starbucks vs Dunkin calories question matters. The two chains structure their menus differently: Starbucks leans on syrups and sauces, while Dunkin leans on flavor shots and swirls. This guide compares their most popular drinks head to head so you know exactly what you are ordering.
Starbucks vs Dunkin Calories: Head-to-Head Comparison
Here is how the most common drinks compare at a medium size (Starbucks Grande 16 oz vs Dunkin Medium 14 oz for hot, 24 oz for iced). All figures are approximate for the standard recipe.
| Drink (Medium) | Starbucks | Dunkin | Lower |
|---|---|---|---|
| Black brewed coffee | 5 cal | 5 cal | Tie |
| Latte (whole milk) | 210 cal | 190 cal | Dunkin |
| Cappuccino | 140 cal | 120 cal | Dunkin |
| Caramel Macchiato | 250 cal | 260 cal | Starbucks |
| Iced Vanilla Latte | 190 cal | 200 cal | Starbucks |
| Mocha (whole milk) | 370 cal | 330 cal | Dunkin |
| Frozen/Frappuccino (caramel) | 380 cal | 670 cal | Starbucks |
| Hot chocolate | 370 cal | 320 cal | Dunkin |
The pattern: Dunkin edges out Starbucks on standard hot lattes and cappuccinos, but Starbucks wins big on frozen blended drinks. Use our Starbucks calorie calculator to check any custom Starbucks build.
3 Key Differences in the Calorie Math
1. Sugar Structure: Syrups vs Swirls
Starbucks uses two sweetening systems: sugar-based syrups (about 20 calories per pump) and sauces like mocha and caramel (about 25–30 calories per pump). Dunkin uses “flavor shots” (unsweetened, 0 calories) and “flavor swirls” (sweetened, about 150–160 calories for a medium). This is the single biggest driver in any Starbucks vs Dunkin calories comparison — a Dunkin swirl adds far more calories in one step than a couple of Starbucks syrup pumps.
2. Default Milk and Size
Dunkin defaults to whole milk; Starbucks defaults to 2% milk. That gives Starbucks a small edge on standard drinks. Sizes differ too — a Dunkin Medium hot is 14 oz versus a Starbucks Grande at 16 oz, so Starbucks holds slightly more liquid (and milk) per “medium.”
3. Frozen Drinks
This is where the two chains diverge most. Dunkin’s Frozen Coffee and Coolattas are blended with a high-sugar base, pushing a medium to 600–800 calories. Starbucks Frappuccinos, while still indulgent, typically land at 300–400 calories for a Grande. If frozen drinks are your go-to, Starbucks is consistently the lighter choice.
Black Coffee and Espresso: A Near Tie
| Drink | Starbucks | Dunkin |
|---|---|---|
| Brewed coffee (medium, black) | 5 cal | 5 cal |
| Americano (medium) | 15 cal | 10 cal |
| Espresso shot | 5 cal | 5 cal |
| Cold brew (medium, black) | 5 cal | 5 cal |
If you drink your coffee black, there is essentially no difference between the two chains on calories. Both brewed coffees are 5 calories, and both offer black cold brew at the same count. The Starbucks vs Dunkin calories gap only opens up once milk, sugar, and flavor enter the picture.
Iced Coffee Comparison
| Iced Drink (Medium) | Starbucks | Dunkin |
|---|---|---|
| Iced coffee, black | 5 cal | 5 cal |
| Iced coffee, cream + sugar | ~120 cal | ~170 cal |
| Iced caramel swirl/macchiato | 250 cal | 290 cal |
| Iced latte (2% / whole) | 130 cal | 150 cal |
| Iced signature/frozen | 380 cal | 670 cal |
On iced drinks, Starbucks tends to run slightly lighter, largely because of the 2% default milk and lower-calorie syrups. Dunkin’s iced signature and frozen drinks climb quickly due to the swirls. For the lightest iced options at either chain, see our low calorie Starbucks drinks guide.
Which Chain Is Better for Low-Calorie Orders?
Both chains can be very low-calorie if you order carefully. The key moves are the same at either one:
- At Starbucks: Order an Americano or cold brew with almond milk and sugar-free syrup, or a skinny latte. Easy to stay under 100 calories. See how to order Starbucks under 100 calories.
- At Dunkin: Order coffee with a flavor shot (0 cal) instead of a swirl, use skim milk, and add a sugar substitute. A medium hot coffee this way is about 25 calories.
The verdict on low-calorie ordering: Dunkin’s unsweetened flavor shots are a slight advantage for adding taste with zero calories, while Starbucks offers more milk alternatives (almond, oat, coconut). Both can deliver a satisfying drink under 100 calories.
Sugar Comparison: Starbucks vs Dunkin
| Drink (Medium) | Starbucks Sugar | Dunkin Sugar |
|---|---|---|
| Caramel flavored latte | 33g | 44g |
| Frozen/Frappuccino | 54g | 90g |
| Iced vanilla | 28g | 36g |
| Hot chocolate | 43g | 40g |
Dunkin’s swirl-based drinks generally carry more sugar than the syrup-based Starbucks equivalents. If sugar is your main concern, Starbucks flavored drinks tend to be the lower-sugar option, though both are high. For the lowest-sugar picks, see our sugar-free Starbucks drinks guide.
Caffeine: Starbucks vs Dunkin
Caffeine is separate from calories but often part of the decision. Starbucks brews a stronger cup: a Grande brewed coffee has about 310mg of caffeine, while a Dunkin medium has about 210mg. For espresso drinks the two are closer, around 150mg for a medium latte at both chains. If maximum caffeine per cup matters, Starbucks brewed coffee wins.
The Bottom Line
The honest answer to the Starbucks vs Dunkin calories debate is that neither chain is universally lighter — it depends on the drink:
- Black coffee: Tie (5 calories each).
- Standard hot lattes and cappuccinos: Dunkin is slightly lower.
- Iced and flavored drinks: Starbucks is usually lighter thanks to 2% default milk and syrup-based sweetening.
- Frozen blended drinks: Starbucks wins clearly — Dunkin’s frozen drinks are among the highest-calorie options at either chain.
- Sugar: Starbucks flavored drinks generally have less sugar than Dunkin swirl drinks.
Order black or lightly customized and the two are nearly identical. Order a frozen or heavily flavored drink and the differences become real. You can verify any Starbucks figure on the official Starbucks menu.
Frequently Asked Questions

Is Dunkin coffee higher in calories than Starbucks?
For plain coffee, no — both are about 5 calories. Dunkin’s flavored and frozen drinks are often higher because its “swirls” add 150 or more calories, while Starbucks syrups add about 20 calories per pump.
Which has more sugar, Starbucks or Dunkin?
Dunkin’s swirl-based flavored and frozen drinks generally have more sugar than the equivalent syrup-based Starbucks drinks. For example, a medium frozen Dunkin drink can have around 90g of sugar versus about 54g in a Starbucks Frappuccino.
Which has more caffeine, Starbucks or Dunkin?
Starbucks brewed coffee is stronger — about 310mg per Grande versus about 210mg for a Dunkin medium. Espresso drinks are closer, around 150mg at both.
What is the lowest-calorie drink at Dunkin and Starbucks?
At both chains, black brewed coffee, black cold brew, and an Americano are all under 15 calories. Adding a flavor shot at Dunkin or sugar-free syrup at Starbucks keeps them nearly calorie-free.
Why do Dunkin frozen drinks have so many calories?
Dunkin’s Frozen Coffee and Coolattas use a high-sugar blended base, pushing a medium to 600–800 calories. Starbucks Frappuccinos use a lighter base and typically land at 300–400 calories for a Grande.
Is a Starbucks latte or Dunkin latte healthier?
A Dunkin medium latte is slightly lower in calories (about 190 vs 210) because of size, but Starbucks defaults to 2% milk and offers more milk alternatives. Both are similar; customization matters more than the chain.
Can I order under 100 calories at both Dunkin and Starbucks?
Yes. At Starbucks, order an Americano or skinny latte with almond milk. At Dunkin, order coffee with a flavor shot, skim milk, and a sugar substitute. Both come in well under 100 calories.
Does Dunkin default to whole milk?
Yes. Dunkin uses whole milk by default, while Starbucks uses 2% milk. This gives Starbucks a small calorie edge on standard milk drinks unless you specify a lighter milk at Dunkin.
Which is better for weight loss, Starbucks or Dunkin?
Neither is inherently better — both offer very low-calorie options if you order black coffee, unsweetened drinks, or skinny/light customizations. The healthiest choice at either chain is plain coffee or an Americano with a splash of low-calorie milk.
