Comparing Starbucks vs Dunkin calories, with Peet’s added into the mix, sounds simple until you actually try to do it, since each chain structures its menu differently. Starbucks leans heavily on syrups and sauces, Dunkin leans on flavor shots and swirls, and Peet’s leans on darker roasts with less customization built in by default. Comparing their most similar drinks head to head reveals some real, and sometimes surprising, differences that go beyond just brand loyalty. This guide walks through how the three chains actually stack up across the drinks people order most.
02
Why Direct Comparison Is Harder Than It Looks
Each coffee chain uses its own base recipes, portion sizes, and default customizations, which means a “medium latte” at one chain is not automatically equivalent to a “medium latte” at another. Starbucks uses tall, grande, and venti as its size names, while Dunkin and Peet’s use small, medium, and large, and the actual ounces behind those names do not always line up perfectly. To make a fair comparison, this guide matches drinks by ounce count as closely as possible rather than relying on the size label alone.
03
Black Coffee and Cold Brew Comparison
Plain black coffee is essentially calorie free at all three chains, and this is the one category where the comparison is genuinely simple.
| Chain | Drink (16 oz) | Calories |
|---|---|---|
| Starbucks | Grande Black Coffee | 5 |
| Dunkin | Medium Black Coffee | 5 |
| Peet’s | Medium Black Coffee | 5 |
All three land in the same place here, since black coffee is black coffee regardless of the brand behind it. The real differences start once milk, sugar, and flavoring enter the picture.
04
Latte Comparison
Lattes reveal more meaningful differences, largely driven by each chain’s default milk ratio and portion sizing.
| Chain | Drink (16 oz, 2% milk) | Calories |
|---|---|---|
| Starbucks | Grande Latte | 190 |
| Dunkin | Medium Latte | 200 |
| Peet’s | Medium Latte | 180 |
The three chains land within about 20 calories of each other for a straightforward latte, which is close enough that milk choice and any added flavoring matter more than which chain you happen to visit. Peet’s runs slightly lower here, largely due to a marginally leaner milk ratio in its standard recipe.
05
Starbucks vs Dunkin Calories: The Flavored Drinks Gap
Flavored drinks are where the three chains diverge the most, since each one uses different syrup formulations and default pump counts.
| Chain | Flavored Drink (16 oz) | Calories |
|---|---|---|
| Starbucks | Grande Caramel Latte | 250 |
| Dunkin | Medium Caramel Swirl Latte | 320 |
| Peet’s | Medium Caramel Latte | 230 |
Dunkin’s flavored lattes tend to run noticeably higher than the other two chains, largely because Dunkin uses a sweetened flavor swirl rather than a syrup added in controlled pump counts. Peet’s, by contrast, tends to run leanest on flavored drinks, since its default sweetness level is calibrated lower than either Starbucks or Dunkin.
06
Cold Foam and Whipped Topping Comparison
Starbucks made cold foam mainstream and still offers the widest variety of cold foam flavors of the three chains. Dunkin has its own version called Cold Foam as well, generally running a similar calorie range to Starbucks.
Peet’s offers whipped cream as its primary topping option rather than a dedicated cold foam program, which tends to add more calories per serving than a comparable cold foam topping would.

07
Iced Drinks and Refreshers
Starbucks has built out the largest refresher and iced tea lineup of the three chains, offering fruit-based options that generally run lower in calories than a flavored coffee drink. Dunkin offers a comparable Refresher line with similar calorie ranges. Peet’s has a smaller iced tea and lemonade selection, generally landing in a similar range but with fewer flavor options to choose from overall.
08
Which Chain Is “Healthiest” Overall?
There is no single winner across the board here, since each chain has categories where it performs better or worse. Peet’s tends to run leanest on flavored espresso drinks due to its more restrained default sweetness.
Starbucks offers the most customization options and the widest range of lower calorie swaps, like sugar free syrups and nonfat milk defaults, which gives customers the most control if they know what to ask for. Dunkin tends to run highest on flavored drinks by default, though ordering black coffee or a plain latte closes that gap significantly.
09
How to Order Lighter at Any of the Three
Regardless of which chain you prefer, the same core principles bring calories down across all three.
- Choose nonfat or a lower calorie milk over whole milk or cream
- Ask for sugar free syrup where available, especially at Dunkin where flavor swirls run high
- Request fewer pumps of syrup than the default recipe calls for
- Skip whipped cream toppings in favor of a lighter cold foam option where offered
- Stick to smaller sizes, since calories scale with cup size at every chain

Price Versus Calories: A Quick Note
While this guide focuses on calories, it is worth noting that Dunkin generally prices its drinks slightly lower than Starbucks or Peet’s, while Starbucks tends to sit at the higher end, particularly for heavily customized orders. Peet’s often lands in the middle. For anyone weighing both cost and calories together, our breakdown of Starbucks extras by cost and calorie looks at this tradeoff specifically for Starbucks customizations.
11
The Bottom Line on Starbucks vs Dunkin Calories
Black coffee is essentially identical across all three chains, and even standard lattes land within a narrow range of each other. The real differences show up once flavoring enters the picture, with Dunkin generally running highest on flavored drinks and Peet’s generally running leanest. Starbucks sits in between but offers the most customization flexibility of the three, which matters most for anyone willing to modify their order rather than take the default recipe as given.
