Half an avocado typically contains about 80–120 calories , depending on the size and variety.

Quick Scoop: The Calorie Range

For most everyday situations, you can safely estimate:

  • Small half avocado (about 50 g): ~80 calories.
  • Average half avocado: ~120 calories.
  • Many forum and calorie-counting communities casually quote “about 80–90 calories” for half a small avocado.

So if you’re logging food, using around 100 calories for half an avocado is a practical middle-ground estimate.

Why The Numbers Differ

Calories in half an avocado vary because of:

  • Size and weight : A denser or larger half will obviously contain more calories; sources using 50 g portions report ~80 calories, while 75 g portions are closer to 120.
  • Variety and ripeness : Different avocado varieties and fat content slightly shift calorie counts, but the range still stays roughly in that 80–120 band per half.

Think of it like this: half a very small avocado is closer to a light snack, while half a big café-style avocado can edge toward the calories in a small handful of nuts.

Nutrition Snapshot (Beyond Calories)

Even though the question is about calories, what you get with those calories matters:

  • About 1–1.5 g protein per half.
  • Roughly 7–11 g fat, mostly heart-healthy monounsaturated fats.
  • Around 4–6 g carbs, with 3–5 g coming from fiber.
  • Helpful amounts of potassium, folate, vitamin K, and vitamin E.

That fiber and fat combo is a big part of why half an avocado feels so filling compared with other foods with similar calories.

Mini “Real Life” Example

Imagine you’re making toast and debating toppings:

  • Half an avocado on toast: ~100 calories, plus fiber, potassium, and healthy fats.
  • A small handful of nuts: often 160–200 calories for a similar “snacky” feel.

From a satiety-per-calorie perspective, half an avocado is a pretty solid deal.

TL;DR:
Most people can count half an avocado as roughly 80–120 calories , with ~100 calories being a good everyday estimate.
