Avocado calories by size and portion

The number of calories in an avocado depends on the amount of edible flesh you eat. Avocado size can vary considerably, so the gram measurements below are estimates rather than fixed serving sizes.

Size / Portion	Edible weight	Calories
Thin slice	~20g	32 kcal
¼ avocado	~50g	80 kcal
½ small avocado	~75g	120 kcal
½ medium avocado	~100g	160 kcal
Small avocado (whole)	~100g	160 kcal
Medium avocado (whole)	~150g	240 kcal
Large avocado (whole)	~200g	320 kcal
Extra-large avocado (whole)	~250g	400 kcal

Calculations use an approximate value of 160 kcal per 100g of avocado flesh. The weight excludes the skin and stone. Added ingredients, such as oil or salt-based seasonings, are not included.

Avocado nutrition per 100g

Avocado contains mostly unsaturated fat, along with fibre, carbohydrates and a small amount of protein. The table shows approximate values per 100g and for a medium serving containing 150g of edible flesh.

Nutrient	Per 100g	150g serving
Calories	160 kcal	240 kcal
Total fat	14.7g	22.1g
— Saturated fat	2.1g	3.2g
— Monounsaturated fat	9.8g	14.7g
Carbohydrates	8.5g	12.8g
— Fibre	6.7g	10.1g
— Sugars	0.7g	1.1g
Protein	2.0g	3.0g
Potassium	485mg	728mg
Folate (vitamin B9)	81µg	122µg

These are reference estimates. Nutrient levels can vary with avocado variety, growing conditions and ripeness.

Why is avocado relatively high in calories?

Avocado is different from many other fruits because it contains a relatively high proportion of fat. Fat provides around 9 calories per gram, compared with about 4 calories per gram from carbohydrates and protein. This helps explain why avocado has more calories per 100g than fruit such as apples, oranges or strawberries.

Much of the fat in avocado is monounsaturated fat, including oleic acid, which is also found in foods such as olive oil. Avocado also provides fibre and a range of vitamins and minerals. Its calorie content does not make it inherently unhealthy; the amount you eat and your overall diet matter too.

Avocado calories compared with other fruits

Comparing calories per 100g is a useful way to see how avocado differs from other common fruits. The values below are approximate and may vary depending on the variety and ripeness.

Fruit	Calories per 100g
🥑 Avocado	160 kcal
🍌 Banana	89 kcal
🍇 Grapes	67 kcal
🍎 Apple	52 kcal
🍊 Orange	47 kcal
🍓 Strawberry	32 kcal

How to calculate avocado calories

If you know the edible weight of your avocado, estimating its calories is straightforward. Using the reference value of 160 kcal per 100g, multiply the weight in grams by 1.6.

Calories = avocado weight in grams × 1.6

For example, 75g of avocado contains approximately 120 calories, while 150g contains around 240 calories. This calculation uses the edible flesh only, not the skin or stone.

If you are making guacamole or avocado toast, remember to include the other ingredients separately. Bread, oil, cheese and other additions can significantly increase the total calories in the meal.

Frequently asked questions

How many calories are in half an avocado?

It depends on the size. Half a small avocado containing around 75g of flesh provides approximately 120 calories. Half a medium avocado containing 100g provides around 160 calories.

How many calories are in a whole avocado?

A whole avocado provides different amounts depending on its edible weight. Using 160 kcal per 100g, a small avocado with 100g of flesh has around 160 calories, while a medium avocado with 150g has around 240 calories.

Is avocado good for weight loss?

Avocado can fit into a weight-management plan. It contains fibre and unsaturated fats, but it is also relatively high in calories. Whether it supports your goal depends on portion size and your overall eating pattern, rather than on one food alone.

How many calories are in avocado toast?

The total depends on the bread and the amount of avocado. For example, one slice of bread containing 130–150 calories with 50g of avocado containing around 80 calories would provide approximately 210–230 calories before any extra toppings.

Does avocado contain protein?

Yes, but not a large amount compared with foods such as eggs, fish, beans or tofu. Avocado contains approximately 2g of protein per 100g and is better known for its unsaturated fats and fibre.

Is avocado high in carbohydrates?

Avocado contains around 8.5g of total carbohydrates per 100g, including approximately 6.7g of fibre in these reference values. The amount of digestible carbohydrate is therefore lower than the total carbohydrate figure.

Do I weigh an avocado with or without the stone?

For the most accurate estimate, weigh the edible flesh after removing the skin and stone. This calculator uses the weight of the flesh only.

Are avocado calories the same in guacamole?

Not necessarily. Plain mashed avocado has a similar nutritional profile to avocado flesh, but guacamole often contains other ingredients such as tomato, onion, lime juice or oil. Its calories per 100g depend on the recipe.
