How Many Calories Are in a Smoothie? USDA Counts for 24 Ingredients and 5 Common Blends
A homemade smoothie usually lands between about 200 and 350 calories for a 16-ounce glass made with fruit and milk, and it can pass 600 once nut butter, oats and yogurt go in. The number is simply the sum of what you put in the blender. Fruit and greens add little, the liquid sets the baseline, and spoonfuls of nut butter, seeds and sweeteners move it the most. Below are USDA figures for 24 common ingredients and five worked examples so you can count your own.
Why two smoothies of the same size can differ by 400 calories
A blender doesn't add or remove calories. Whatever goes in comes out in the glass, so a smoothie's calorie count is plain arithmetic. What makes smoothies hard to guess is that the ingredients look alike once they're blended. A cup of spinach and a quarter cup of peanut butter both disappear into the same pale green, but one adds 7 calories and the other close to 400.
Three groups of ingredients decide most of the total:
- The liquid. It's the biggest single ingredient by volume, and the range is wide: unsweetened almond milk is about 39 calories a cup, whole milk about 149 and orange juice about 122.
- The fats. Nut butters, seeds and avocado are dense. Two tablespoons of peanut butter add about 191 calories, more than the banana and the milk in many recipes.
- The sweeteners. A tablespoon of honey is about 64 calories, and it's easy to pour two.
Fruit sits in the middle. A cup of berries or a banana adds roughly 50 to 105 calories, along with fiber you don't get from juice or honey. Leafy greens barely register.
Calories in common smoothie ingredients
All figures are calculated from USDA FoodData Central (SR Legacy) values for the amounts shown. Cup measures are approximate. If you track closely, weigh the ingredients and use the grams.

Notes: the SR Legacy entry for chia seeds doesn't list sugar. Protein powders and flavored yogurts vary too much by brand to list, so read the Nutrition Facts panel on the tub. Ice and water add nothing.
Five common smoothies, counted
Each of these makes one large glass, about 16 to 20 ounces. The totals are the sums of the rows in the table above.
Strawberry banana with 2% milk: about 279 calories
One medium banana (105), a cup of frozen strawberries (52) and a cup of 2% milk (122). It has about 34 g of sugar, all of it from the fruit and the milk's lactose, and about 10 g of protein. This is the classic and a fair baseline for "a normal smoothie."
Green smoothie with almond milk: about 233 calories
A cup of spinach (7), a banana (105), a cup of pineapple (82) and a cup of unsweetened almond milk (39). Swap the almond milk for orange juice and it rises to about 316. Stir in a tablespoon of honey and it's about 297, and the honey alone brings 17 g of added sugar.
Mango yogurt with orange juice: about 325 calories
A cup of mango (99), a cup of orange juice (122) and a 6-ounce cup of plain whole-milk yogurt (104). It tastes like dessert, and it's the highest in sugar of the five, around 51 g, because both the mango and the juice are sweet. Using half juice and half water saves about 60 calories without changing the flavor much.
Berry flax with almond milk: about 212 calories
A cup of blueberries (84), a cup of frozen strawberries (52), a cup of unsweetened almond milk (39) and a tablespoon of ground flaxseed (37). It's the lightest of the five and still has about 9 g of fiber, roughly a third of what many adults aim for in a day.
Peanut butter banana breakfast: about 620 calories
A banana (105), 2 tablespoons of peanut butter (191), a 6-ounce cup of plain nonfat Greek yogurt (100), a cup of 2% milk (122) and a third of a cup of rolled oats (102). It also has about 37 g of protein and 7 g of fiber, so it can work as a full breakfast. As a side to a meal, it's a lot.

Where hidden calories come from
Most surprise totals come from a few habits, not from the fruit.
Free-pouring nut butter. A heaping spoonful from the jar is often 2 tablespoons or more, close to 200 calories. Level a measuring spoon for a week and you'll know what your scoop really holds.
Juice as the base. A cup of orange juice adds about 122 calories and almost no fiber. The Dietary Guidelines for Americans recommend that at least half of the fruit you eat come from whole fruit rather than 100% juice. A smoothie made with whole fruit and a lighter liquid follows that advice. Our smoothie vs juice guide explains what juicing leaves behind.
Sweeteners on top of sweet fruit. Ripe banana, mango and pineapple are already sweet. The Dietary Guidelines count honey and syrups as added sugars and advise keeping added sugars under 10% of daily calories. On a 2,000-calorie day that's 200 calories, or about 50 g, and one tablespoon of honey uses roughly a third of it. A Medjool date has a similar amount of sugar but comes with some fiber. Many smoothies need neither.
Bigger glasses. Café smoothies are often 20 to 32 ounces. Under FDA menu-labeling rules, chain restaurants with 20 or more locations have to post calories, so check the menu board before you order a large.
How to make a lighter smoothie that still fills you up
Cutting calories doesn't have to mean a thin, watery drink.
- Swap the liquid first. Going from whole milk to unsweetened almond milk saves about 110 calories a cup. Unsweetened soy milk saves about 70 and keeps most of the protein.
- Use frozen fruit for body. Frozen strawberries make a thick, cold smoothie at 52 calories a cup, so you need less ice and no ice cream. Our guide to making a smoothie thicker has more ways to add body without adding much.
- Measure the dense add-ins. One level tablespoon of nut butter instead of two saves about 95 calories and still tastes of peanut.
- Add greens freely. A cup of spinach or kale adds about 7 calories and a lot of color.
- Use protein that fills you up. Plain Greek yogurt adds 17 g of protein for 100 calories, which helps a smoothie hold you until lunch.

FAQ
How many calories are in a typical homemade smoothie? Most fruit-and-milk smoothies in a 16-ounce glass come to about 200 to 350 calories. Recipes with nut butter, oats, seeds and yogurt can reach 500 to 650.
Are fruit smoothies high in sugar? They can be. A smoothie with mango and orange juice can carry 50 g of sugar, mostly natural fruit sugar. Using whole fruit instead of juice, and skipping honey or syrup, keeps the sugar down and the fiber up.
What is the lowest-calorie liquid for a smoothie? Water and ice add none. Among milks, unsweetened almond milk is lowest at about 39 calories a cup in USDA data. Unsweetened soy milk is about 80, with much more protein.
Does blending fruit add calories? No. Blending doesn't change the number of calories in the fruit. The total is the same as eating the ingredients whole.
Can a smoothie be a meal replacement? A smoothie with protein, fiber and some fat, like the 620-calorie peanut butter banana breakfast above, can stand in for a meal. A 200-calorie fruit smoothie usually works better as a snack.
