Calories and Caffeine in Dunkin' Coffee

There are 5 calories in a medium Dunkin’ Coffee. You can choose from a variety of dairy and flavor options at Dunkin’, including oat milk, coconut milk, skim milk, or whole milk.

Adding dairy increases the number of calories and slightly reduces the total caffeine as the amount of milk replaces the amount of coffee in the cup.

Dunkin’ Coffee Nutritional Information

There are only five calories in a cup of Dunkin’ hot brewed coffee before adding any sweetener, dairy, or flavoring syrup.

Adding Flavor Increases Calories

Flavor options include French Vanilla, Caramel Swirl, and Mocha Swirl. Each flavor option adds about 155 calories, based on a medium.

Here is a summary of total calories in a medium Dunkin’ Coffee based on the flavor added:

Medium coffee without flavor has 5 calories
Medium coffee with Butter Pecan Swirl has 170 calories
Medium coffee with Caramel Swirl has 170 calories
Medium coffee with French Vanilla Swirl has 170 calories
Medium coffee with Mocha Swirl has 160 calories

Amount of Caffeine in Dunkin’ Coffee

There are approximately 210 milligrams of caffeine in a medium size Dunkin’ Coffee drink.

Here is the amount of caffeine in a Dunkin’ Coffee without any flavoring or dairy, listed by size:

A Small Dunkin’ coffee has 180 milligrams caffeine
A Medium Dunkin’ coffee has 210 milligrams caffeine
A Large Dunkin’ coffee has 270 milligrams caffeine
An XL Dunkin’ coffee has 330 milligrams caffeine

The amount of caffeine is slightly higher when you enjoy your coffee black, without any dairy, oat milk, or other add-ins.

Why? Because flavor syrup and/or dairy takes up space in the cup. Without any of those add-ins, you have more coffee in your cup and thus more caffeine.
