A medium avocado contains roughly 225 to 320 calories, depending on the variety and exact size. The USDA lists a whole avocado weighing about 201 grams (7 ounces) at 322 calories, 29 grams of fat, 17 grams of carbohydrates, and 4 grams of protein. Smaller Hass avocados, the dark-skinned type you’ll find in most grocery stores, tend to land closer to 225 calories per fruit.
Why the Calorie Range Is So Wide
Avocados aren’t standardized like a can of soda. A “medium” avocado at one store might weigh 150 grams of edible flesh, while another weighs over 200 grams. The skin and pit account for roughly 25 to 30 percent of the total weight, so two avocados that look similar on the outside can differ meaningfully once you scoop out the flesh. If you’re tracking calories closely, weighing the edible portion gives you a much more accurate number than eyeballing it. Per 100 grams of flesh, avocado runs about 160 calories.
Hass vs. Florida Avocados
The variety matters more than most people realize. Hass avocados, the smaller ones with bumpy, dark skin, are higher in fat and calories. Per two-ounce portion, a Hass (often labeled “California”) avocado has about 80 calories and 8 grams of fat. The same portion of a Florida avocado, which is larger with smooth, bright green skin, has about 60 calories and 5 grams of fat.
That sounds like a small difference per serving, but it adds up across a whole fruit. A large Florida avocado can weigh twice as much as a Hass, yet its lower fat density means the total calorie count may be similar or even lower than you’d expect for its size. If you’re choosing between the two for calorie reasons, Florida avocados give you more volume for fewer calories. Hass avocados have a richer, creamier texture because of the higher fat content, which is why they dominate the market.
What a Standard Serving Actually Looks Like
Most nutrition labels and dietary guidelines don’t consider one whole avocado a single serving. The FDA and the California Avocado Commission define one serving as one-third of a medium avocado. That works out to roughly 75 to 80 calories, which is closer to what you’d spread on a piece of toast or slice into a salad. If you eat half an avocado at a time, you’re looking at about 110 to 160 calories depending on the size.
This serving distinction matters if you’re comparing avocado to other foods on a nutrition label. When a package of guacamole lists 50 calories per serving, that’s typically based on a two-tablespoon portion, not the amount most people actually eat in one sitting.
Where Those Calories Come From
Fat accounts for the vast majority of avocado’s calories. Of the roughly 29 grams of fat in a whole avocado, most is monounsaturated fat, the same type found in olive oil. This is why avocado now qualifies for the FDA’s “healthy” label despite being a high-fat food. The fat in avocado also slows digestion, which is part of why half an avocado can keep you feeling full for hours in a way that a similar calorie count from bread or fruit wouldn’t.
The 17 grams of carbohydrates in a whole avocado are misleading at first glance, because a large portion of that is fiber. A medium avocado contains roughly 10 grams of fiber, which your body doesn’t absorb as energy. That brings the net digestible carbs down to about 7 grams for the entire fruit, making avocado unusually low in sugar for something that grows on a tree. For context, a medium banana has about 14 grams of sugar. An avocado has less than 1 gram.
Calorie Counts for Common Portions
- One-third of a medium avocado (one serving): 75 to 80 calories
- Half a medium avocado: 110 to 160 calories
- One whole medium Hass avocado: 225 to 250 calories
- One whole large avocado (201g edible flesh): about 322 calories
- Two tablespoons of mashed avocado: roughly 45 to 50 calories
These numbers assume a Hass avocado. If you’re using a Florida variety, reduce the estimate by about 25 percent for the same weight of flesh.
