Costco Strawberry Banana Smoothie Nutrition
Costco publishes nothing for it. Here is what the drink is actually made of, and how to rebuild it at home.
Costco strawberry banana smoothie nutrition comes down to the fruit and whatever you pour over it: the pack is strawberries and banana, frozen, with no liquid, dairy or sweetener in the bag. Costco publishes no nutrition figures for the smoothie, so there is no official number to quote. Made at home the drink runs 180 to 393 calories, and the gap is almost entirely what you pour over the fruit.

The thing most people are asking about is a bag of frozen fruit, and a strawberry banana pack is exactly that: strawberries and banana, no liquid, no dairy, no sweetener. So the bag’s own panel tells you very little. Whatever you pour over it — water, orange juice, whole milk, oat milk — is the single biggest lever on where the drink ends up, and the fruit stays identical either way.
Costco publishes nothing for the food court cup or the frozen packs, so any precise calorie count you find attached to its name came from a user-submitted database or a photo of an in-warehouse label. Your own pour, though, is answerable: same fruit five ways, changing only the liquid and the base. Our smoothie calorie calculator takes your proportions if they differ.
Strawberry banana, rebuilt five ways at home
One serving each, all starting from frozen strawberries and frozen banana. The water version and the orange juice version use identical fruit, so the only thing separating them is the pour.
What actually sets the number
A frozen strawberry banana pack is exactly what it says: fruit, frozen, in a bag. It contains no liquid, no dairy, no sweetener. That means the bag's own panel tells you almost nothing about the drink you end up holding. The number you care about is set after you open it.
Strawberries are mostly water. Banana is not. It is the dense, starchy-sweet part of the blend and it carries most of what the fruit contributes. Packs that lean banana-forward for texture land higher than packs that lean strawberry, even when the bag weight is identical.
Blended drinks sold ready-made usually start from a juice or fruit puree base rather than water, because it is sweeter, cheaper and pours consistently. Do the same at home, orange juice over the fruit instead of water, and the total moves before a single spoonful of anything else goes in.
Food court cups are sized for a warehouse, not a snack. A blend that is unremarkable per cup becomes a lot of drink once it is poured into something you carry with two hands. When you compare a homemade glass to a counter-bought cup, check the serving before you compare anything else.
Honey, agave, turbinado and fruit-juice concentrate all do the same thing to the total: they add sugar and nothing else. On an already-sweet strawberry banana base they are the easiest line to remove, and the one most likely to be there in a version somebody else made for you.
How to make it lighter without losing the drink
Measure the liquid the first few times. A cup of juice looks like nothing going into a full blender jug, and it is the easiest thing in the whole recipe to overpour without noticing you have done it.
Bulk frozen strawberries and a bag of frozen banana slices give you the same drink as a pre-mixed pack, with the ratio under your control. Freeze ripe bananas yourself in portions and you get consistency without paying for the packaging.
If the drink tastes flat on water, reach for a riper banana or more strawberry before you reach for honey. Fruit sugar arrives with fiber attached. A spoon of syrup arrives on its own.
Whole milk makes a smoothie creamy by adding fat. Plain Greek yogurt over unsweetened almond milk does the same job on texture and brings protein along with it. Same taste, more protein.
