Calories in Starbucks Decaf Iced Latte with low-fat milk match the lactose-free version exactly, running from 90 in a Tall to 140 in a Venti.
A Grande comes to 128 calories with fat at 4.4g and sugar at 11.9g, saving roughly 40 calories over the whole milk version at this size. Since decaf espresso doesn’t change the calorie count, these numbers mirror standard low-fat Caffe Latte served over ice.
