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.
