A medium apple has about 95 calories. That’s for a raw, unpeeled apple weighing roughly 182 grams, which is the size you’d typically grab from a grocery store display. Most of those calories come from natural sugars and carbohydrates, with virtually no fat.
Calories by Apple Size
Not all apples are the same size, and the calorie count scales proportionally with weight. A small apple (around 149 grams) has roughly 77 calories, while a large one (around 223 grams) comes in closer to 116. The differences aren’t dramatic, but they’re worth knowing if you’re tracking intake closely. As a quick rule of thumb, every 100 grams of raw apple contains about 52 calories.
What’s in Those 95 Calories
A medium apple packs 25 grams of carbohydrates, 19 grams of naturally occurring sugar, 4.4 grams of fiber, and less than half a gram each of protein and fat. It’s also about 86% water by weight, which is part of why apples feel so refreshing and filling relative to their calorie count.
The fiber number matters more than it looks. At 4.4 grams, a single apple delivers roughly 15 to 18 percent of the daily fiber most adults need. A good chunk of that fiber is pectin, a soluble fiber that forms a gel-like substance in your gut and slows digestion. The rest is insoluble fiber concentrated in the skin, which helps with regularity.
Why the Skin Changes the Equation
Peeling an apple strips away most of its fiber and a significant share of its beneficial plant compounds. The calorie count doesn’t change much when you remove the skin, but you lose the nutrients that make those calories worth eating. If you’re baking apples and leave the skin on, you retain most of the fiber. Peel them to make applesauce, and most of it disappears.
Apple Juice vs. a Whole Apple
A cup of apple juice runs about 114 calories, which isn’t far from a whole medium apple. The difference is what’s missing. Juice has almost no fiber, which means your body absorbs the sugar much faster. Blood sugar spikes more quickly after juice than after eating a whole apple, where the intact fiber slows everything down.
There’s also a volume issue. A whole apple takes time to chew, fills your stomach, and triggers fullness signals. A glass of juice goes down in seconds and leaves you ready to eat again shortly after. If you’re choosing between the two for a snack, the whole fruit is the better option calorie for calorie.
Apples and Fullness
Apples are one of the more filling fruits you can eat, largely because of their pectin content and high water volume. Pectin triggers the release of hormones in your gut that signal satiety to your brain. Research has shown a clear dose-dependent relationship: the more pectin consumed, the greater the increase in these satiety hormones and the less food eaten overall. In practical terms, eating an apple before a meal can take the edge off your hunger enough to reduce how much you eat at the table.
This is one reason apples show up so often in weight management advice. At under 100 calories with a solid fiber payload and high water content, they deliver a lot of chewing and stomach-filling volume for relatively few calories.
Raw vs. Cooked Calories
Baking or cooking an apple without adding sugar, butter, or other ingredients doesn’t meaningfully change its calorie count. What changes is the texture (softer, sweeter-tasting as sugars concentrate) and a drop in vitamin C, which breaks down with heat. If you cook apples with the skin on, you keep most of the fiber. The moment you peel, puree, or strain them, fiber content drops significantly.
Where cooked apple calories can climb fast is in preparation. A baked apple stuffed with brown sugar and butter, or apple slices in a pie, can easily triple or quadruple the calorie count. The apple itself isn’t the problem; the additions are. A plain baked apple with a sprinkle of cinnamon stays right around the same 95 calories as a raw one.
