A medium apple has about 95 calories. That’s for a whole apple with skin, roughly 3 inches in diameter and weighing around 182 grams. Most of those calories come from natural sugars and carbohydrates, with virtually no fat and only 1 gram of protein.
Calories by Apple Size
The 95-calorie figure applies to a medium apple, but apples obviously vary. A small apple (about 2.75 inches across, roughly 150 grams) lands closer to 77 calories. A large apple (3.25 inches or bigger, around 220 grams) pushes toward 115 calories. If you’re grabbing one from a grocery store, most fall in that medium range unless they’re noticeably small or oversized.
Apple variety matters less than you might expect. A Fuji and a Granny Smith of the same size are within a few calories of each other. Sweeter varieties have slightly more sugar, tarter ones slightly less, but the difference per apple is negligible.
What’s Actually in Those 95 Calories
A medium apple contains about 25 grams of carbohydrates, 19 grams of naturally occurring sugar, and 3 grams of fiber. That leaves roughly 22 grams of net carbs if you subtract the fiber. There’s zero fat and only 1 gram of protein. Apples are essentially a carbohydrate food, but the type of carbohydrate matters.
The 3 grams of fiber come mostly from the skin, which is why eating an unpeeled apple is worth it nutritionally. That fiber slows down how quickly the sugar hits your bloodstream. Whole apples have a glycemic index of 39 (out of 100) and a glycemic load of just 6, both considered low. For comparison, white bread scores around 75 on the glycemic index. So despite containing 19 grams of sugar, an apple doesn’t spike blood sugar the way processed sugary snacks do.
Apples vs. Apple Products
The calorie count changes significantly once you move away from a whole raw apple. A cup of unsweetened applesauce runs about 100 calories but lacks much of the fiber and feels less filling. A cup of apple juice contains around 115 calories with almost no fiber at all. Dried apple rings concentrate the sugar and calories into a much smaller volume, so a handful can easily exceed what a whole apple provides.
Research on satiety shows that eating apple slices lowers how much you eat at your next meal more effectively than applesauce or juice, even when the calorie, fiber, and weight of the portions are matched. The physical act of chewing a solid apple appears to send stronger fullness signals than drinking or spooning the same calories.
How Cooking Changes the Count
Baking or stewing an apple without added ingredients doesn’t change its calorie content. Heat breaks down cell walls and softens the fruit, but the total energy stays the same. What does change is volume: a baked apple shrinks as water evaporates, so it looks smaller and feels less filling than the raw version. The real calorie jump comes from what you add. A tablespoon of butter adds 100 calories, a tablespoon of brown sugar adds 50, and a standard baked apple recipe can easily triple the calorie count of the fruit itself.
Why Apples Work Well as a Snack
At 95 calories with 3 grams of fiber, a medium apple is one of the more filling options for its calorie cost. The combination of water content (apples are about 86% water), fiber, and the time it takes to chew through one means you feel more satisfied than you would from 95 calories of crackers or a granola bar. The low glycemic load also means you’re less likely to get a quick energy spike followed by a crash and renewed hunger.
If you’re counting calories or tracking macros, apples are straightforward to log because they come in their own natural portion size. One apple, roughly 95 calories, 25 grams of carbs. No measuring cup needed.
