Apple calories, by size
An apple with the skin is 52 calories per 100 g — the lowest calorie density of any common fruit on this site. USDA’s extra small is 101 g, about 53 calories, and the sizes climb from there.
Per 100 g, raw, with skin
| Serving | Weight | Calories | Protein | Carbs | Fat |
|---|---|---|---|---|---|
| 1 extra small (2-1/2" dia) | 101 g | 53 | 0.3 g | 13.9 g | 0.2 g |
| 1 cup slices | 109 g | 57 | 0.3 g | 15.1 g | 0.2 g |
| 1 cup, quartered or chopped | 125 g | 65 | 0.3 g | 17.3 g | 0.2 g |
| 1 small (2-3/4" dia) | 149 g | 77 | 0.4 g | 20.6 g | 0.3 g |
| 1 medium (3" dia) | 182 g | 95 | 0.5 g | 25.1 g | 0.3 g |
| 1 large (3-1/4" dia) | 223 g | 116 | 0.6 g | 30.8 g | 0.4 g |
With skin, core removed.
Against a banana, which is the comparison people make
| Per 100 g | Calories | Protein | Carbs | Fat |
|---|---|---|---|---|
| Apple, raw with skin | 52 | 0.3 g | 13.8 g | 0.2 g |
| Banana, raw | 89 | 1.1 g | 22.8 g | 0.3 g |
Per 100 g an apple is 52 calories against a banana’s 89, so nearly half as dense. Per piece the gap narrows, because apples are often larger. Both are fruit and both are fine; if you are choosing on calories, the apple wins by more than most people expect.
Variety changes taste, barely touches calories
Granny Smith, Gala, Honeycrisp and Fuji differ in sugar content by a few percent — enough to taste, not enough to log differently. USDA carries "apples, raw, with skin" as one record for good reason. Pick the one you like; the arithmetic does not care.
The skin, and juice
These figures include the skin, which carries most of the fiber (2.4 g per 100 g) for essentially none of the calories. Peeling is a straight loss.
Apple juice is a different food. Juicing removes the fiber and leaves the sugar, so a glass delivers the sugar of several apples with none of the fullness of one. That is not a moral point, it is a satiety one — the whole apple is the version that stops you eating.
Where the "apple" in your log went wrong
Rarely anywhere. At 52 calories per 100 g, misjudging an apple by 50 g costs you 26 calories. Like broccoli, this is a food where precision is not worth the effort. Spend it on the oil.

Common questions
About 53 for USDA’s extra small at 101 g, at 52 calories per 100 g with the skin. Larger apples scale from there.
Only marginally. Sugar content varies by a few percent between varieties — enough to taste, not enough to log differently.
Per 100 g, substantially — 52 against 89. Per piece the gap is smaller because apples are often larger.
It carries most of the fiber, 2.4 g per 100 g, for almost no calories. These figures include it.
