How many calories are in an avocado?
Quick answer: avocado has about 160 calories per 100 g of flesh. A serving on a nutrition label is usually one third of a medium avocado (about 50 g), which is around 80 calories.
Avocado calories by amount
Avocados vary a lot in size, so weight is the reliable measure. Using 1.6 calories per gram:
| Amount of flesh | Approx. calories |
|---|---|
| 30 g (a few slices) | 48 |
| 50 g (one third of a medium fruit) | 80 |
| 100 g (about half a large avocado) | 160 |
| 150 g | 240 |
| 170 g (a large avocado) | 272 |
The flesh of one avocado commonly ranges from about 100 g to 170 g, so a whole avocado is roughly 160 to 270 calories.
Where the calories come from
Avocado is unusual among fruit because most of its calories come from fat. Per 100 g, the USDA lists about:
- Fat: 14.7 g, most of it monounsaturated
- Carbohydrates: 8.5 g
- Fiber: 6.7 g
- Protein: 2 g
- Potassium: about 485 mg
That is why avocado has more than three times the calories of an apple by weight (see how many calories are in an apple) but very little sugar.
Is avocado high in net carbs?
No. About 8.5 g of carbohydrate per 100 g, with 6.7 g of that being fiber, leaves roughly 1.8 g of net carbohydrate. See net carbs vs total carbs for how the subtraction works and its limits.
Hass avocado vs other varieties
Nutrition tables for “all commercial varieties” are averages. Hass avocados, the small dark-skinned kind common in US shops, are richer in fat than some larger green varieties, so their calories per 100 g are a little higher. For calorie counting, the average figure is a fair estimate.
How to weigh avocado
Scoop out the flesh and weigh it without the skin and stone. Weighing the whole fruit overstates the calories. Convert grams to ounces with our grams to ounces converter.
Frequently asked questions
Is avocado fattening? Any food adds to your total calories, so portions matter. A third of an avocado is a modest addition, while a whole one on toast with other ingredients adds up.
How much avocado is one serving? One third of a medium avocado (50 g) on the US label.
