How many calories are in an apple?
Quick answer

A medium apple weighing 180 grams (6.3 oz) delivers around 94 calories, according to USDA FoodData Central. Per 100 grams (3.5 oz) of apple flesh, that works out to 52 calories — one of the lowest values among everyday fruits.

    Nutrition facts and composition

    An apple is roughly 85 percent water, which explains its low energy content. Per the German BLS food database, 100 grams of apple flesh provide 13.8 grams of carbohydrate — including 10.4 grams of sugar, mostly fructose and glucose — plus 2.4 grams of fiber. Protein and fat content are negligible.

    Chart: How many calories are in an apple?

    Calories by apple size

    Size (with core)Calories
    Small (approx. 130 g / 4.6 oz)68 kcal
    Medium (approx. 180 g / 6.3 oz)94 kcal
    Large (approx. 220 g / 7.8 oz)114 kcal

    Differences between varieties

    Calorie density varies only slightly from one apple variety to the next. Granny Smith is the lowest-calorie common variety at around 48 calories per 100 grams, thanks to a lower sugar content and higher acidity. Sweeter varieties like Pink Lady or Fuji sit at the upper end with 55 to 58 calories per 100 grams. The difference per apple is usually less than 10 calories — not enough to matter for your calorie balance.

    The core accounts for roughly 10 percent of an apple's weight. If you eat around the core, you can subtract about 10 calories from a medium apple — in practice, that level of precision is rarely worth the effort.

    Apples as a snack

    With its high water content and moderate fiber, the apple counts as a filling snack with comparatively low calorie density, according to data from Germany's Federal Center for Nutrition (BZfE). A study by Flood-Obbagy and Rolls (2009) found that eating a whole apple before a meal reduced calorie intake at that meal by an average of 15 percent. The effect disappeared with pulp-free apple juice.
