Smoothie Calorie & Macro Calculator
Add up the calories, protein, carbs and fat in a homemade smoothie from its actual ingredients.
How it works
Total = Σ (amount × nutrition per unit) for each ingredient, across calories, protein, carbs and fat
A smoothie’s calories come almost entirely from what you add, not the blending, so summing each ingredient’s contribution gives an accurate label. Fruit and juice drive carbs, yogurt and powder drive protein, and nut butter and whole milk drive fat and total calories fastest. Reference values here use common supermarket foods; a tablespoon of nut butter alone adds nearly 100 kcal, which is why smoothies can quietly become 600+ kcal drinks.
Worked example
One banana (105), 100 g berries (50), 150 g Greek yogurt (89), 200 ml milk (100), one scoop whey (120) and a tbsp of nut butter (94) total about 558 kcal, with roughly 51 g protein, 60 g carbs and 14 g fat.
Frequently asked questions
Does blending add or remove calories?
Neither — blending only changes texture. The calories equal the sum of the ingredients, whether you blend, chew or drink them.
Why does my smoothie have so many calories?
Liquid calories add up fast because you drink them quickly and they are easy to over-pour. Nut butter, full-fat milk, honey, juice and multiple fruits are the usual culprits — measure them rather than free-pouring.
What if I use a different milk or yogurt?
Swap the amount and it recomputes against the reference values shown. For a precise result with almond milk, skyr or plant powders, adjust to your product’s label since densities vary a lot.
