If you've ever wondered how many calories in an avocado before adding it to your toast or salad, you're not alone. The short answer: a whole medium avocado contains roughly 240 calories, while half an avocado comes in at around 120 calories. The USDA reports avocados at 160 calories per 100 g of edible flesh. Size, variety, and how much you actually eat all change the final count — so let's break it all down.
Calories in an Avocado by Serving Size
The FDA's official serving size for avocado is one-third of a medium fruit (about 50 g), which contains 80 calories. In practice, most people eat half or a whole avocado at a time — and the real-world numbers look quite different.
| Serving | Weight | Calories |
|---|---|---|
| 1 tablespoon (spread) | ~15 g | 24 kcal |
| 1/3 medium (FDA serving) | 50 g | 80 kcal |
| Half avocado (typical) | ~75 g | ~120 kcal |
| Half avocado (large half) | ~100 g | ~161 kcal |
| 1 cup cubed | ~150 g | ~240 kcal |
| Whole small avocado | ~130 g | ~208 kcal |
| Whole medium avocado | ~150 g | ~240 kcal |
| Whole large avocado | ~200 g | ~322 kcal |
The most accurate approach is to weigh the flesh after removing the skin and pit. If you track your intake with Caloria, you can also snap a photo and let AI estimate the portion and calories instantly.
Full Avocado Nutrition Facts
Calories tell only part of the story. Here is the complete nutrient profile for 100 g of raw avocado flesh, based on USDA FoodData Central:
| Nutrient | Per 100 g | % Daily Value |
|---|---|---|
| Calories | 160 kcal | — |
| Total Fat | 14.7 g | 19% |
| — Monounsaturated Fat | 9.8 g | — |
| — Saturated Fat | 2.1 g | 11% |
| Carbohydrates | 8.5 g | 3% |
| — Fiber | 6.7 g | 24% |
| — Sugar | 0.7 g | — |
| Protein | 2 g | 4% |
| Potassium | 485 mg | 10% |
| Folate (B9) | 81 mcg | 20% |
| Pantothenic Acid (B5) | 1.4 mg | 28% |
| Vitamin K | 21 mcg | 18% |
| Vitamin E | 2.1 mg | 14% |
| Vitamin C | 10 mg | 11% |
ℹ️ Potassium Powerhouse
Avocados deliver 485 mg of potassium per 100 g — nearly double what you get from a banana on a per-calorie basis. Adequate potassium supports healthy blood pressure and muscle function.
Nearly 67% of avocado's fat is heart-healthy monounsaturated fat, primarily oleic acid — the same fatty acid that gives olive oil its health credentials. The remaining fat is split between polyunsaturated and saturated.
Hass vs. Florida Avocado Calories
The Hass avocado (small, dark-skinned, creamy) accounts for about 95% of US avocado sales. Florida avocados (larger, bright green) are marketed as "Slimcados" — and the calorie difference is real.
| Variety | Calories per cup | Fat per cup | Standout Nutrients |
|---|---|---|---|
| Hass | 384 kcal | 35 g | Higher in folate, beta-carotene, Vitamin A |
| Florida (Slimcado) | 276 kcal | 23 g | Higher in Vitamin C, Vitamin E |
Florida avocados have roughly 28% fewer calories per cup — but also less of the creamy monounsaturated fat that makes Hass so nutritionally distinctive. If you're counting calories, Florida is the leaner choice; if you want maximum micronutrient density, Hass wins.
Why Avocados Are Calorie-Dense — And Why That's Okay
With 160 kcal per 100 g, avocados are among the most calorie-dense fruits you can eat. A medium apple sits at 52 kcal per 100 g by comparison. The explanation is straightforward: fat contains 9 kcal per gram — more than twice the energy density of carbohydrates or protein.
But calorie density alone doesn't tell the full story. As we explore in our guide on whether all calories are the same, the source of calories shapes how your body responds. Avocado fat is predominantly monounsaturated, which promotes fullness and slows gastric emptying. Research published in Nutrition Journal found that adding half an avocado to lunch significantly reduced hunger and the desire to eat over the next three hours compared to a control meal.
That satiety effect is significant — foods that keep you fuller tend to naturally prevent overeating later in the day.
Is Avocado Good for Weight Loss?
The evidence is encouraging. A 12-week randomized controlled trial published in Nutrients found that participants who ate one avocado daily lost a comparable amount of weight to the control group, while also seeing reductions in triglycerides and improvements in gut microbiota markers.
A 2022 systematic review and meta-analysis further confirmed that avocado consumption does not cause weight gain — even when added on top of an existing diet. And a long-term Harvard cohort study following roughly 111,000 participants found that eating two or more avocado servings per week was linked to a 16% lower risk of cardiovascular disease.
The practical takeaway: avocados fit well into a calorie-aware diet when portion size is considered. Half an avocado (120 calories) as part of a balanced meal delivers genuine nutritional value. Two whole avocados as a mindless snack is a different story — for more context, see our guide on calories and weight loss.

Frequently Asked Questions
How many calories are in half an avocado?
Half a medium avocado contains approximately 120 calories, assuming around 75 g of edible flesh. A larger half at 100 g provides about 161 calories. Weighing the flesh gives the most precise count.
How many calories are in a whole avocado?
A whole medium avocado (roughly 150 g of flesh) contains about 240 calories. Large avocados can reach 300–322 calories; small ones may fall between 160–210 calories.
Is avocado high in calories for a fruit?
Yes — avocados are among the most calorie-dense fruits because of their fat content. Most fruits provide 40–80 kcal per 100 g; avocados deliver 160 kcal per 100 g. That fat is predominantly monounsaturated and highly satiating, which is why avocados don't behave like typical high-calorie foods in practice.
How many net carbs are in an avocado?
Per 100 g, avocado has 8.5 g of carbohydrates minus 6.7 g of fiber, leaving just 1.8 g of net carbs. This makes avocado one of the best fruits for a ketogenic or low-carb diet.
How much avocado should I eat per day?
Most nutrition experts suggest half to one whole avocado per day for healthy adults. This delivers 120–240 calories, strong fiber and micronutrient coverage, and heart-healthy fats — all within a reasonable calorie budget.
Track Your Avocado Intake
Knowing that half an avocado has 120 calories is a useful starting point. Understanding how it fits into your full day's nutrition is where real results come from.
