How many calories are in an apple?
A medium apple has about 95 calories. USDA's medium apple is about 3 inches (7.5 cm) across and weighs 182 g, eaten with the skin. Nearly all of it is carbs, about 25 g, including 4.4 g of fiber. Protein and fat are tiny.
USDA puts an apple at about 86 % water (Apples, raw, with skin), which is why such a big piece of fruit stays under 100 calories.
Apple calories by size
USDA FoodData Central lists a raw apple with skin at 52 calories per 100 g and gives a standard weight for each size (USDA FoodData Central, Apples, raw, with skin). Calories, carbs and fiber are calculated from the per-100 g values and rounded.
| Size | Diameter | Weight | Calories | Carbs | Fiber |
|---|---|---|---|---|---|
| Extra small | 2½ in (6.5 cm) | 101 g | 53 | 13.9 g | 2.4 g |
| Small | 2¾ in (7 cm) | 149 g | 77 | 20.6 g | 3.6 g |
| Medium | 3 in (7.5 cm) | 182 g | 95 | 25.1 g | 4.4 g |
| Large | 3¼ in (8 cm) | 223 g | 116 | 30.8 g | 5.4 g |
| 1 cup, sliced | 109 g | 57 | 15.1 g | 2.6 g | |
| 1 cup, chopped | 125 g | 65 | 17.3 g | 3.0 g |
Why some labels say 130 calories
The FDA's nutrition poster for raw fruit lists one large apple at 130 calories (FDA raw fruits nutrition facts). Its "large" apple weighs 242 g, heavier than USDA's large apple of 223 g. At 52 calories per 100 g, 242 g works out to about 126, and labels round to the nearest 10.
So neither number is wrong. They just picture different apples. Variety matters too: a small snack apple and a big one from the supermarket can be 100 g apart.
How to weigh it
The quickest check is to weigh the whole apple once. Multiply the grams by 0.52 and you have the calories. Your scale counts the core and stem too, which most people don't eat, so you'll land slightly high. That's fine for an everyday estimate. Do it a few times and you'll know your usual apple by eye.
Good to know
Apple with peanut butter is a classic snack. The apple is the light part; two tablespoons of peanut butter add more than the apple itself, so check that page before you log the pair. Comparing fruit? A medium banana has about 105 calories.
Track it the easy way
Weighing every apple gets old fast. With Calorie AI, just say what you ate, for example "a large apple with peanut butter," and the app estimates the calories and macros for you. It's an estimate, so "small" or "large" helps when you know it.
