How many calories in avocado?
Last updated: July 10, 2026
Short answer: a whole medium avocado (about 150 g) has240 calories, with 3 g protein, 12.8 g carbs, 22 g fat, and 10 g fiber. Half an avocado is roughly 120 calories, and 100 g is about 160. The fat is mostly heart-healthy monounsaturated, which is why avocados are so calorie-dense.
Avocados feel like a health food — and they are, packed with fiber, potassium, and good fats — but they are also one of the more calorie-dense fruits. That is not a problem; it just means the number on your plate depends heavily on how much you eat. Here is exactly what a whole one, a half, and 100 g cost you.
Avocado calories by serving size
| Serving | Calories | Protein | Carbs | Fat |
|---|---|---|---|---|
| Whole avocado (150 g) | 240 kcal | 3 g | 12.8 g | 22 g |
| Half avocado (~75 g) | ~120 kcal | 1.5 g | 6.4 g | 11 g |
| Per 100 g | 160 kcal | 2 g | 8.5 g | 14.7 g |
The whole avocado also delivers about 10 g of fiber, a big chunk of a day's target, and it is high in potassium — more per gram than a banana. Most of the 22 g of fat is monounsaturated, the same kind found in olive oil.
How avocado fits your calorie goal
Whether an avocado helps or hurts depends on your daily target. Find that number first with thecalorie calculator. If you are losing weight, avocado works well inside a calorie deficit because its fiber and fat are very filling — half an avocado at about 120 calories adds creamy satisfaction without blowing your budget. If you are building muscle or just eating at maintenance, a whole avocado is an easy way to add 240 quality calories and healthy fats.
Because fat carries 9 calories per gram, avocado is fat-heavy on the macro side: 22 g of fat is where most of those 240 calories come from, with only 3 g of protein. If you are tracking your split, see calories in protein, carbs & fat to understand how those grams turn into calories and how to balance the rest of your day around a fat-rich food like this.
Log your avocado in seconds
The tricky part with avocado is portion size — a "half" can easily become a whole one, and the calories double. Instead of guessing, the MyPlate app lets you log an avocado by snapping a photo or scanning the barcode on a bag of guacamole, and it fills in the calories and macros for you. Do the same for everything else you eat and checkcalories in common foods to see how avocado stacks up against the rest of your day.
Frequently asked questions
How many calories are in one avocado?
A whole medium avocado weighing about 150 g has roughly 240 calories. Along with those calories it gives you about 3 g of protein, 12.8 g of carbs, 22 g of fat (mostly heart-healthy monounsaturated fat), and 10 g of fiber. Avocados are calorie-dense because most of their weight is fat, and fat carries 9 calories per gram versus 4 for protein and carbs.
How many calories are in half an avocado?
Half a medium avocado has about 120 calories — half of the roughly 240 in a whole one. That half also carries about 1.5 g of protein, 6.4 g of carbs, 11 g of fat, and 5 g of fiber. Half an avocado is a common, satisfying serving that adds creamy texture and healthy fats to a meal without using your whole calorie budget.
Is avocado good for weight loss?
Avocado can absolutely fit a weight-loss plan. It is calorie-dense, so portion size matters, but it is also very filling thanks to its fiber and fat, which helps curb hunger between meals. It is naturally high in potassium and healthy monounsaturated fat. The key is to count it: half an avocado at about 120 calories works well in a calorie deficit, while eating two whole ones adds up fast.
What are the macros in an avocado?
A whole 150 g avocado has about 3 g of protein, 12.8 g of carbs, and 22 g of fat, with 10 g of that carb total coming from fiber. It is a high-fat, high-fiber, lower-protein food, and the fat is mostly monounsaturated — the same kind found in olive oil. Per 100 g, an avocado runs about 160 calories.
