Frequently Asked Questions
How many calories are in a Signature Latte?
Calories depend on the size: Small (10 oz) 250, Medium (14 oz) 340, Large (20 oz) 440 calories (with the default milk). A Medium has 340 calories. Choosing nonfat or a plant milk, or skipping whipped cream, lowers the count.
How much caffeine does a Signature Latte have?
Dunkin' doesn't publish a caffeine figure for the Signature Latte; it varies with the number of espresso or coffee shots. Ask in store for specifics.
Is the Signature Latte vegan or dairy-free?
No. The Signature Latte contains dairy (in the milk and/or the syrup or sauce), so it can't be made fully vegan or dairy-free even with a plant-based milk.
How much does a Signature Latte cost?
Dunkin' doesn't publish national drink prices, and they vary by location, size, and any customizations. Check the Dunkin' app or your nearest store for current pricing.
Nutrition data compiled from Dunkin' public sources, as of 2026-07. Calories are for the plain/base drink from Dunkin official sources. Milk-based drinks use the whole-milk standard formulation from the official nutrition PDF; skim-milk options are lower. Where the live product page and the PDF conflict on a size, that size's calories are left null. Caffeine values are the official medium/default figure published on each Dunkin product page; Dunkin notes these are approximate and vary by brewing method and location. Small and Large caffeine are left null because the product pages only expose the medium value. Dunkin does not publish official national menu prices; prices are set by individual franchisees and vary by location. Prices are left out rather than estimated.
